SBM is committed to the powder industry's ultrafine mill machinery and equipment more than 10 years of innovative and substantial development. In the market there are many loyal customers and considerable sales. High-quality ultra-fine grinding to customers with high efficiency, high yield, high yield of production, many processing enterprises are the only choice. In the production of ultra-fine grinding, after the bulk material is crushed to the required particle size of about 1cm by jaw crusher, the material is sent to the storage hopper by the hoist, and then the material is evenly and continuously sent to the main mill room for grinding by the electromagnetic vibration feeder. The grinded materials are sent to the powder feeder for classification by the air flow of the fan. Under the action of the impeller of the powder feeder, the materials that do not meet the fineness requirements fall into the grinding chamber for re-grinding, and the materials that meet the fineness requirements enter the cyclone powder collector through the air flow, are separated and collected, and are discharged into the finished powder through the discharge device. If the ground material contains a certain amount of water, The amount of heat that is generated when you grind, the gas in the mill chamber evaporates and expands to change the gas flow rate of the system, In addition, the problem of sealing at the junction of the feed port and the pipes causes the air flow in the system to lose balance. For this reason, the ultra-fine powder mill guides the excess gas into the bag filter through the exhaust pipe valve arranged at the air outlet of the fan, and discharges the excess gas after being purified, so as to realize the environmental protection production while adjusting the air flow balance of the system. SBM adopts high-quality materials and design principles for the processing of wear-prone parts such as grinding rolls and rings. In the work, the grinding roller of the ultrafine mill is not in contact with the grinding disc, and has less wear and long service life. The grinding roller can be turned out to the outside of the casing for inspection and repair, and the roller sleeve can be replaced, the lining plate is convenient and fast, and the shutdown loss can be reduced. Single lubricating station is used for roller lubrication, and double pump-mdash is used for single roller circuit. The mode of pumping and working at the same time not only makes the roller bearings lubricated and cooled, but also avoids the leakage of oil stored in the roller bearing chamber. What are you hesitating about with such material processing equipment? Ultra-fine grinding is worth more than that. When the right equipment is selected for you, SBM will tailor you to the quality of the production program, ultra-fine grinding will also shine.

With the development of China's cement industry, the performance requirements of milling equipment are getting higher and higher. Ordinary ball mills are forced to make improvements because of some problems. At the same time, the vertical roller mill with superior performance has gradually gained market recognition, but vertical roller mill also has defects. So some people proposed to use vertical grinding and ball milling, what will happen? The combined grinding of the vertical roller mill and the ball mill is a new grinding process in which the vertical roller mill is connected in series with the ball mill. The vertical roller mill first pre-grinds the clinker and the mixed material. After the clinker is pre-grinded, the mill is set to be inclined. The inner screening device, the escaped bulk material is blocked by the screening device, and returned to the vertical roller mill for grinding and grinding. The smaller material passes through the sieve, and the fine powder after the screening enters the ball mill; the material is crushed and sheared and pulverized, the particle size becomes very small, and there are many cracks, of which 30% is less than 80um, and the mixture enters the ball mill. In the future, the ball mill is made with good grinding conditions; the top of the vertical roller mill is designed as an O-Sepa separator with a small air inlet, and the powdered layer on the vertical grinding disc is reduced by strong ventilation, and the powder is qualified after the powder selection. The material enters the finished product warehouse, and the coarser material enters the mill to continue grinding, and the material is secondly ground by the ball mill, such as the finished product warehouse. The process characteristics of the combined grinding process are mainly as follows: 1) The vertical roller mill first pre-grinds the clinker. After the clinker is pre-grinded, the granules are rolled and sheared, and there are many cracks. After the mixture enters the ball mill, it produces a good grinding condition for the ball mill, which greatly improves the system grinding ability. 2) The vertical roller mill adopts a static and dynamic ring to ensure the thickness of the layer. 3) According to the characteristics of the grinding efficiency, the gap of the sieve can be conveniently selected to determine the particle size entering the ball mill, thereby increasing the output of the ball mill. 4) The sorting system is different from the ordinary high-fine grinding screen. The main difference is: it belongs to dynamic active sorting, the sorting efficiency and precision are higher, the adjustment is convenient and reliable, and the ventilation area inside the mill is not affected. 5) This combined grinding makes the cement particle size distribution and particle morphology tend to be reasonable, solves the key common technical problems of particle characteristics and surface energy, mechanical energy and chemical energy, and greatly improves the gelation efficiency. The mechanical energy activation of siliceous, silico-aluminum industrial solid waste is combined with chemical energy activation. Milling equipment is an important machine equipment in cement production. The energy consumption of traditional milling equipment accounts for more than 70% of the total electricity consumption in total energy consumption. Therefore, the improvement of existing equipment is imperative. The combination of ball mills and vertical roller mills will inevitably promote the vigorous development of the cement industry.

How to realize the cement ball mill high yield when we are in the use of cement cement mill output amounted to less than our request we should how to solve it, and without harming the material on the basis of quality, in order to be able to make cement ball mill can meet customer satisfaction standards, we elaborate discussion finally developed solutions, here we come right away a detailed introduce you. First of all, reducing the grain-size of grinding materials in the past few years, cement grinding grain-size has not been paid attention to by cement enterprises. In recent years, cement grinding technology has raised the grain-size of cement into an important position. More wear and tear; "Has been recognized by the industry; More wear and tear; That is to change the original into the mill 30mm material particle size under 3mm. At this stage, the production of crusher manufacturers have launched a high fine hammer crusher, screen rolling crusher, roller press and so on. According to the actual situation of the enterprise, the author changed the original jaw crusher into the ultra-fine hammer screen crusher, and the grinding particle size decreased from the original 30mm to below 5mm, thus improving the output of the mill. After that, the author used a roller press to reduce the grain size of the grinding machine to below 2mm and increase the output by more than 50%. Before the unit began to produce cement is open circuit system, cement fineness is not easy to control, fluctuations. For this reason, the unit invested hundreds of thousands of yuan, changed the open-circuit pulverizing system to closed-circuit pulverizing system, added a high-efficiency rotor powder selecting machine, updated a high-efficiency cloth bag dust collector, so as to improve the specific surface area of cement and increase the strength of cement. SBM juki adopts roller press, scatter grading machine, Ф 3.8 x 13 m grinding system of cement mill, ball millproduction was from 60 ~ 70 t/h, up to 100 ~ 120 t/h. Thirdly, controlling the water content of grinding materials and controlling the integrated water content of grinding materials by 1.5% at the temperature are the basic requirements to ensure the high quality and high yield of the ball mill. If the water content of grinding material is too high, it will cause the roll press to squeeze material cake too solid, not easy to break up; At the same time, it is easy to cause poor ventilation in the mill, blocking the compartment plate, grate plate, paste ball, paste lining plate, dews of the dust collector. The author of the unit of the mixing material into the plant moisture, material production process drying moisture strict control, serious assessment, and the temperature into the grinding material strictly control in the range of technological requirements, to ensure the normal operation of the mill.

Nowadays, machine sand has been widely recognized as the main source of construction sand. The use of sand making machine equipment to make cobblestone, granite, bluestone, limestone, stone, scraps and scraps into machine-made sand can not only turn waste into treasure, liberate the occupied space, but also create high economic benefits. A good deed. So what are the advantages of machine sand processed by sand making machine? First, the standard of construction sand is 4.75mm or less, but different engineering has different requirements on the fineness modulus of sand. The mechanism sand equipment can process the coarse sand of the building and can also process the fine sand of the building, which can meet the fineness modulus. It is more flexible than the river sand, and the application is more extensive;  Second, the standardized mechanism sand production line is generally a mode of sand powder separation, low soil content, through the quantitative mixing of stone powder, fine sand, coarse sand, it is easier to adjust the fine aggregate of reasonable particle size, can be well filled a gap of coarse aggregate; Third, the mechanism sand can usually be produced nearby, so it may be more advantageous in price than river sand because it has a lot less transportation costs. Fourth, the particle shape of the mechanism sand is close to the river sand. Through the optimization of the cavity structure of the sand making machine, the material is made into sand and the impact and friction are also subjected to many angles, which can form a good shape.

1. In order to prevent whiteness in stainless steel casting, besides technological measures, it is necessary to make the wall thickness not too thin (some data point out that when the wall thickness is more than 15 mm, rounded corners must be used at the corner of the casting with metal mould. 2. Because of the non-yielding nature of the metal and core, in order to facilitate the removal of castings and withdrawal moulds, the casting inclination of stainless steel castings should be larger than that of sand castings, which should generally be 30%-50%. 3. The thickness of inner wall and inner rib of stainless steel castings should generally be 0.6-0.7 of the zhuguangzhi.37ix.com.cnjinyinzhi.37ix.com.cnsekazhi.37ix.com.cn tongfengg.37ix.com.cnshusongdaih.07858.netshusongdaif.07858.netthickness of the connecting outer wall. Otherwise, because the inner wall (rib) is cooled slowly, cracks are likely to occur at the junction of inner and outer wall when the castings shrink. 4. The minimum wall thickness of stainless steel casting should be larger than that of sand casting because of the fast heat dissipation of metal mould, and the minimum wall thickness of various casting alloys and different sizes of casting.

In the process of producing stainless steel castings, the problem is that the castings have shrinkage defects. In order to deal with this problem, many experts have conducted research. Now, Solitaire Casting has summarized the following points for dealing with the shrinkage of stainless steel casting: 1. Altering the orientation of the casting runner; 2. Reasonable process planning. The sprue in the sprue is located at the opposite side of the casting, and is scattered for a few times. The metal liquid that first enters the thick wall is first condensed, and then condensed at the thin wall, so that the ground reaches equilibrium and condensation. For machine tool castings with uniform wall thickness, multiple ingates and vents are used. There are many internal gates, scattered and evenly distributed to balance the total heat. The venting holes are fine and numerous, that is, the exhaust gas is clear and has a heat dissipation effect; 3. In the thick part and the hot section of the stainless steel casting structure, rapid condensation is realized, and the fundamental balance of the temperature field of the casting is artificially formed. Choose cold iron in the table, some use zircon sand, chromite sand or special paint with large heat storage.

The jaw crusher has the advantages of large production capacity, low energy consumption per unit of output, long life of the liner and large crushing ratio. The mass of a single hammer head is large, and the moment of inertia of the hammer head is large, which overcomes the weakness of the hammer head of other crushers and the high loss of wearing parts, and has the characteristics of large grain size, high crushing ratio and low maintenance cost. Applicable to the crushing of mining, cement, road, railway, coal, metallurgy, building materials and other industries. This series of crushers is becoming the first choice for the crushing industry. When the materials enter the crushing chamber, the bulk materials are piled up on the special middle strips in the machine. After crushing, the particle size is larger than the required material along the tangential direction of the new materials along the hammer. The counter-attack plate is broken again, so that the coarse and medium-breaking pieces are in one step, and finally the materials that meet the requirements are discharged through the integration of the raft plates.

When the jaw crusher enters the unbreakable material (such as iron balls, iron blocks, etc.) in the crushing chamber, the back thrust plate is used as the safety component of the crusher to protect the main components of the equipment from damage. As the tooth plate continues to wear, the discharge port becomes larger and the product becomes thicker. In order to obtain a qualified product grain size, the size of the discharge port needs to be adjusted regularly. Jaw crusher thrust plate (also known as the bracket), in addition to transmitting power to make the moving plate to swing back and forth, but also has a safety insurance function, changing its length can also play a role in regulating the discharge port. When the jaw crusher enters the unbreakable material (such as iron balls, iron blocks, etc.) in the crushing chamber, the back thrust plate is used as the safety component of the jaw crusher to protect the main components of the equipment from damage. The back thrust plate is generally cast into a whole with cast iron, and a groove or a plurality of small holes are opened in the middle portion to reduce the strength of the section; or two pieces can be cast, and then connected by screws (or rivets) to form a combined thrust plate. When the unbreakable material enters the crushing chamber, the equipment is overloaded, and the huge crushing force is transmitted to the thrust plate, causing the thrust plate to be broken or the screw of the combined thrust plate to be cut, and the machine stops working and plays an insurance role. As the tooth plate continues to wear, the discharge port becomes larger and the product becomes thicker. In order to obtain a qualified product size, it is necessary to periodically adjust the size of the discharge port. There are two main methods for adjusting the discharge port: (1) Gasket adjustment, that is, a set of gaskets is placed between the backrest of the backrest plate and the rear wall of the frame to increase or decrease the number of gaskets or change the thickness thereof, so as to adjust the discharge port. The method is compact in structure and reliable in regulation, and the large and medium-sized jaw crusher often uses this adjustment method. 2) Wedge adjustment is made by two wedges placed between the rear seat of the thrust plate and the frame, suitable for small crushers.

The sand making machine is the main crushing equipment in the sand and gravel production line, and the loss is also very large. Many customers have doubts about the wear of the sand making machine, and it is suspected that it is a quality problem of the sand making machine. Some are caused by improper use during use. Only by paying attention to the maintenance and maintenance of the sand making machine can the sand making machine fully play its role, prolong the service life of the sand making machine equipment, and solve the problem of tight sand and stone materials more effectively. . The following SBM Heavy Industry introduces the maintenance and maintenance of the sand making machine. The bearings of the sand making equipment are the most prone to wear, and the parts bear most of the load when the equipment is in operation. Therefore, we need to use good lubricants in our work, and keep them clean at all times. If the lubricating oil is not clean, it will increase the wear between bearings, bearings and other parts. In addition, it should be noted that the bearing cannot be overheated, and the overheating will cause the running efficiency of the bearing to decrease, which will affect the normal operation of the equipment. The transmission of the sand making machine equipment, the V-belt should be properly adjusted to ensure that the V-belt is evenly stressed. When driving with a dual motor, it should be properly distributed and the same strength. Maintenance of the transmission gear, long-term friction loss between the transmission gear will also affect the life of the machine. Lubricants used in response to previous bearing problems are also an important one. After using for a period of time, the hatch should be opened to see the inside of the sand making machine, the silo, the lining of the impeller, the wear level of the wear-resistant material, if it is found that the wear should be replaced in time to ensure the work of the sand making machine effectiveness.
