How to solve the problem of excessive vibration and noise of the mill?
The main component of limestone is calcium carbonate. Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and burned into quicklime. Lime includes quick lime and hydrated lime. The main component of quicklime is CaO, which is generally massive, pure white, and light gray or light yellow when containing impurities. Quicklime absorbs moisture or adds water to become slaked lime, slaked lime is also called slaked lime, and its main component is Ca (OH) 2. Slaked lime is formulated into lime mortar, lime paste, lime mortar, etc., which is used as coating material and tile adhesive. Limestone can be used in many aspects after being ground by mill equipment, such as plastics, rubber, sealing adhesive materials, paints, paper, ink, etc. Shanghai SBM Machine Co., Ltd. is a mill manufacturer specializing in the development and production of crushing and milling engineering technology products. It specializes in grinding and crushing of limestone, calcite, dolomite, mica and other ore materials. Pioneering and innovative development strategy, facing the main battlefield of economic construction, according to the domestic and foreign market demand, the introduction of advanced foreign high-end technology, research and development of Raymond mill, overpressure mill, high-pressure suspended roller mill, strong pressure mill Machines, high-pressure mills, Raymond mills, desulfurization mills, sand and gravel production lines and other series of equipment have the domestic advanced level, some products have reached the international advanced level, and have been rated as excellent "Raymond mill manufacturers", excellent "Crusher manufacturer". We all know that the mill equipment runs empty before feeding, the sound is very loud, part of it is the sound made by the motor, and the other is that when the grinding roller rotates in the grinding cabin, a loud metal mill Pressure sound, so these are normal. When the ground material enters the grinding chamber, the noise will gradually decrease as the grinding roller rolls the material. This is because the grinding roller is rolling the material, and the noise is not so loud. When crushing the material, the blade of the Raymond mill will throw the material up and squeeze and grind it by the grinding roller of the mill to achieve powder formation. The finished powder will be blown up by the fan and enter the pipeline through the analysis machine , And then fall into the powder accumulator. During the decades of production and operation of SBM Machinery Co., Ltd., it has been a painstaking effort to develop and improve the milling machine. Through the return visits to the company's users, many users report that the milling machine is really good. If the powder machine equipment takes a little longer, some equipment will have some vibration and noise. In response to these problems reflected by users, the company immediately held a technical meeting to study the cause of this problem, and issued a military order. Within five working days This problem is solved and the user is given a satisfactory answer. If the main vibration of the mill is severe, it should be stopped and checked. First check whether the materials are accumulated and not discharged, and then the vibration caused by the mill, and then check whether the grinding roller and grinding ring of the mill are damaged. This is also the cause If the cause of vibration and noise is as described above, replace the grinding roller or grinding ring; this way the fault is removed. Another reason can also cause vibration, that is, the anchor bolts, the loosening of the anchor bolts, and the main unit of the mill cannot be fixed properly. When the material enters, the rotation of the motor will cause the main unit to swing, causing a large vibration failure. When this happens, you should stop immediately and tighten the anchor bolts. The operability of the mill is very important. It should be carried out in strict accordance with the operation manual. If a fault occurs, it should be repaired immediately. The mill with faults must not be forced to work to avoid greater losses. These are the experiences summed up by SBM Machinery Co., Ltd. during the sales return visit. Regardless of whether or not you buy a SBM Machine Co., Ltd. mill, SBM will answer your questions. Welcome friends to come to SBM Machine Co., Ltd. Crusher base visit!

Analysis of the causes of uneven fineness of Raymond mill
As a modern milling equipment, Raymond mill itself will encounter various problems in the production process, such as performance degradation and wear of wearing parts. Recently, some customers have reported that the fineness of the milling of the Raymond mill is uneven. Then, Shanghai SBM Heavy Industry made an analysis, the specific contents are as follows: 1. Hardness of raw materials For different materials, the hardness is different. The hardness directly affects the grinding difficulty and fineness of the Raymond mill, so the harder the material, the greater the degree of grinding. In the process of using Raymond mill, reasonable ingredients should be used to ensure that the size of the material is uniform and the fineness of the mill. 2. Opening height and size of classifier During the installation of the Raymond mill, if the size of the opening of the classifier is not adjusted properly, it will affect the grinding operation and the fineness of the grinding. Therefore, in the installation and production process of Raymond mill, it is necessary to pay attention to check the opening size and height setting of the classifier. 3. Damage of the impeller blade of the analyzer During the grinding of materials by Raymond Mill, if the blade of the analyzer is seriously worn, the fineness of the material after grinding will become coarse, which will affect the quality of the grinding. At the same time, if the blade of the analysis machine is seriously worn, it will affect the overall performance of the equipment, so as to shorten the use time of the equipment. 4. Wear of grinding roller and grinding ring In the production process of Raymond mill, the grinding roller and the grinding ring are in direct contact with the material. In the long-term grinding process, different degrees of wear will occur. Once the grinding roller and the grinding ring are seriously worn, it will affect the fineness of the equipment degree.
Why the screening process in the gravel production line is critical
The finished product of the sand and gravel production line includes both small-grained sand and large-granularity stone. The sieving of the raw material of the finished product is mainly carried out by the round vibrating screen of the sand and gravel production equipment. The production of sand and gravel materials is divided into links such as crushing, screening and VSI Crusher. The quality control of sand and gravel aggregates is mainly based on the particle size and grading requirements of concrete aggregates. Advanced and mature crushing equipment, vibrating screens and standard aperture drying are used to ensure The grading quality standards and regulations determined by the produced concrete aggregate composite specifications. 1. Screen size control: The screen for screening coarse aggregates can be a square mesh screen made of polyurethane material. The size of the mesh is divided into 5mm, 10mm, 20mm, 40mm, 80mm and other specifications according to the aggregate gradation. The production process Except for the gravel inspection, every month or every 20,000-30,000 cubic meters of production needs to be inspected and repaired once to ensure the integrity of the production equipment. In water conservancy and hydropower projects, multi-layer screening and classification are commonly used. In small projects, because of the small amount of dashi used, drum screens can be used for individual production as needed. Second, the screen removal of impurities: the inclination angle of the screen and the amount of raw materials that need to be screened are strictly controlled, and a reliable and stable washing system is equipped for it. The layout of the water spray holes should be uniform, and the water pressure should be adjusted to the appropriate pressure during washing. The purpose is to keep the water uniformly covering the entire screen and keep the screen tools clean at all times. Therefore, after the stone material is crushed, it is also very important and key to do a good job of sieving the stone material, because the sieving of the finished material directly affects the particle shape of the subsequent finished product, and thus affects the quality of the finished product.
Facing the price and quality of Raymond mill, what choice have you made
When buying a Raymond mill, you have a dilemma in terms of equipment price and quality. It is difficult to choose. The better the price is, the more expensive it is. In the current market, price has become the key word to measure the quality of things. According to the current market conditions, the economic status quo in recent years reflects that many customers want to change the original production model and are facing a situation of tight economic conditions. Therefore, I would like to remind you whether you have counted the relationship between price and quality. First of all, low price is the current transaction method for everyone, and seemingly simple requirements are difficult to achieve. For example, buying a Raymond mill is an example. If a customer wants to find a suitable buyer in Shanghai to reach a cooperative relationship, then There are countless large and small manufacturers in Shanghai. More than half of the ideal cooperation is found in many manufacturers, just like finding a needle in a haystack. Then, the grinding customers face the following difficult choices. Secondly, there are many manufacturers of Raymond mills, which is dazzling and difficult to judge the strength of the manufacturers and the quality of the equipment. And the manufacturers are divided into three, six, nine, etc. Even if the strength of the manufacturers is to be figured out, they still need to face selection difficulties, because it is difficult to make a judgment on the price. Third, the type of Raymond mill manufacturers, their small-scale enterprises, their own strength is not good, the technology is not hard enough, and the main equipment price is relatively low. Medium-sized enterprises have their own average scale, low level of enterprise strength, not cheap product prices, and focus on professional and technical levels. Its large enterprises have strong comprehensive strength, but are expensive, focusing on service strategies of all aspects of quality and service. However, there is a contradiction between purchasing Raymond mill equipment and economic strength, and it is difficult to choose. At the same time, I don't know much about the actual situation of several manufacturers in the phase, and I'm afraid of being cheated. Finally, according to the above situations, as a manufacturer can understand, the above two points are also summarized. The price and quality concerns of Raymond mills are based on their own judgment, and the quality is controlled by the manufacturer. If you need users of Raymond mill equipment, you can call for detailed consultation.
Matters needing attention for vertical mill parts cleaning
Cement vertical mill is a new type of vertical roller mill developed by our company for the final grinding process of cement clinker. It integrates grinding, drying and classification.

Application of SBM vertical slag mill in slag fine powder production line
The ore powder produced by our company's vertical roller mill can be used in the field of cement. Not only can the ore powder be widely used, but it can also ensure the quality of the cement, and also obtain great economic benefits. The vertical mill has a large output and low energy consumption, which fully meets the measurement requirements for the construction of large-scale milling stations. Vertical mill production process, slag fine powder production line, a large number of slags will be generated during the opening of the crushing yard and ore mining. After long-term accumulation, the number of slags generated will be innumerable. If they are not used, they will waste recycling resources. Therefore, in recent years, the rational treatment of slag has become one of the problems that have been solved. With the development of the domestic economy and the continuous improvement of related technologies, slag has also been effectively solved. The vertical mill is a necessary equipment for processing high-hardness ore, and it is also a necessary equipment for slag processing. This equipment is a deep processing equipment developed by SBM for industrial waste processing, making it well used in slag deep processing applications. To achieve the goal of zero pollution and zero emissions, this equipment can fully meet all the requirements of slag processing, and has not brought large profits to investors. The following is the structure principle of SBM heavy machinery slag vertical mill: The raw slag of the slag vertical mill enters the feeding bin through the grabber, and is fed by the conveyor belt into the screw feeding device and fed into the SBM roller vertical mill. After the measurement, the material rotates with the grinding disc from the center to the center under the action of centrifugal force. The edge moves. After the process of compaction, deaeration and grinding, the material is taken up by the hot air entering from the air ring on the edge of the grinding disc and dried instantly. The finer particles are taken to the classifier for sorting, and the coarse powder is returned. Grind the disc again. The qualified fine powder is taken into a bag dust collector, and the air powder is separated after the finished product is collected. After the finished product is collected, it is transported into the finished product bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Some difficult-to-grind large-grain materials (and iron knobs and iron slag) enter the external circulation system through the slag outlet at the wind ring. After removing iron, they are fed into the mill by the hoist and ground again.
