Factors affecting the quality of crusher dischargeWhen we buy a crusher, there are many factors that need to be considered. One of the very important points is the quality of the crusher's output, because the super-high output quality is what every user hopes to achieve, because the crusher's output Quality directly affects the interests of enterprises, so what factors affect the quality of the crusher's output?
1. Crushing ratio
The crushing ratio is what everyone should know, it refers to the ratio of the particle size of the imported material to the crushed finished material, so the larger the ratio, the larger the crushing ratio and the higher the crushing quality, and vice versa. Shows that the lower the crushing quality. The crusher refers to the high needle-like content of the crushed material. When the crushing ratio is small, not only the quality of the output is low, but also the internal circulation of the crusher increases, and the wear of the crusher increases, which will reduce the production efficiency.
2. Feed size
The feed particle size also affects the output quality. When the feed particle size is reduced from 100mm to 50mm, the needle-like flake content in the finished material decreases by 38%, and the output quality of the crusher will also decrease.
3. Cycle load
The operation of the crusher will form a closed loop system. If the discharge port is increased at this time, the load in the circulation will be increased, and the shape of the stone particles will become better. In this process, the increase in the circulation load will also cause the system The wear of each equipment increases, but when the discharge port is enlarged, the load of the main crushing motor can be reduced, and the finished material grains will be better.
4. Open and closed loop
Those who are familiar with the production performance of the crusher know that in the secondary crushing process, the cycle separates the circuit and the closed circuit. The open circuit is called the first screening and then the crushing, and the closed circuit is called the first crushing and then the screening, the first screening and then the crushing refers to The material after the primary crushing is screened through the finished product screen and then enters the secondary crushing feed inlet for crushing. In this way, the output of the finished material will increase and the content of needle flakes will also increase. Crushing first and then screening means that all the first-level crushed materials enter the feed port of the second-level crusher, and then enter the finished product screen for screening after re-breaking. Since the entire system is a closed system, there is no loss of crushed materials during this period. Although the cycle load is relatively large, the product has good grain shape and high quality of discharge.
