Factors affecting the quality of jaw crusher discharge

When we buy a jaw 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 discharge quality is what every user hopes to achieve, because the discharge quality of the jaw crusher directly affects the interests of the enterprise, then what factors affect the discharge quality of the jaw crusher?
1. Crushing ratio
The crushing ratio is something that everyone should know. It refers to the ratio of the particle size of the imported material to the crushed finished material. Therefore, the larger the ratio, the larger the crushing ratio.The higher the crushing quality, on the contrary, the lower the crushing quality.The jaw 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 jaw crusher will also decrease.
3. Cycle load
The operation of the jaw crusher will form a closed loop system. If the discharge port is enlarged at this time, the load in the circulation will increase, and the stone grain shape will become better.In this process, the increase of the cyclic load will also increase the wear of the equipment in the system.But when the discharge opening is enlarged, the load of the main crushing motor can be reduced, and the finished material particles will be better.
4. Open and closed loop
People who are familiar with the production performance of the jaw 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.Screening first and then crushing refers to the material that has been crushed in the first stage after being sieved through the finished product screen and then enters the second crushing feed inlet for crushing. In this way, the output of finished materials will increase,the pin flake content also increases.Crushing first and then sieving means that all the first-level crushed materials enter the feed port of the second-level jaw crusher, and then enter the finished product sieve for screening.Since the entire system is a closed system, there is no loss of crushed materials during the period. Although the cycle load is relatively large, the product has good grain shape and high quality of output.
