For the development of construction waste crushers, the technology is constantly being carried out, but at any time, in the production of materials, the machine will inevitably need to adjust the discharge port, and the adjustment process will be on the equipment. The particle size of the finished product and the efficiency of the equipment have an impact, but this adjustment is inevitable for better production. For the construction waste crusher currently used on the market, the measurement and adjustment of the discharge port is convenient because of the simplification of its structure, the advancement of technology and the realization of intelligence, but in the early days when the machine was used, the technology was still Not too developed, the structure of the equipment is also more complicated, what is the method used for the measurement of the discharge port? By querying the data, it can be found that the method used for the early measurement of the discharge of the construction waste crusher is relatively simple - put the shot (or lead and lead) into the empty crusher and measure the discharge of the crusher. The size of the pressed shot, lead and lead columns to identify the size of the discharge port is relatively primitive. Although the size of the discharge port can be measured, it is more troublesome and less convenient than the current measurement standards. In actual production, the purpose of measuring the discharge port of the construction waste crusher is to accurately adjust the parameters in the production and ensure the balance between the finished product and the production capacity. These are important for the production process. In addition, the size of the discharge port of the same type of construction waste crusher can only be adjusted within a specific range. If it exceeds this range, it will cause changes in the efficiency of production, etc., at any time, The law of change. The article mainly introduces the early measurement method of the discharge port of the construction waste crusher. On this issue, we introduce in detail the measurement method and the significance of the measurement - better adjustment of equipment parameters to meet the demand for production capacity and finished products. Then it is analyzed that in the production, the adjustment of the discharge opening needs to be controlled within a certain range, and the adjustment process cannot be carried out arbitrarily, and it needs to be strictly carried out according to the production requirements.
