Analysis of the reasons for the failure of the crusher discharge
#1
For the production process of the Jaw Crusher For Crushing, whether it is the occurrence of failure, the analysis of the cause of the decline in production, or the resolution of unreasonable discharge, it is an important operation in production, and the operation in these aspects is to ensure the production. Benefits, different phenomena are caused by different reasons. Here is to introduce the causes of the phenomenon that the discharge is not up to standard.
Reason one, the crush ratio
The crushing ratio refers to the ratio of the particle size of the imported material and the finished product after crushing. The larger the ratio, the larger the crushing ratio, and vice versa. For the production process of the crusher, the pinch-like content increases when the crushing ratio is large. Therefore, in production, the adjustment of the crushing ratio is an important measure to ensure the discharge. Of course, the crushing ratio is too small, which will result in a decrease in the output of the whole system, an increase in the internal circulation, and an increase in the wear of the Cone Crusher. Selection needs to be appropriate;
Reason two, feed granularity
For the crusher, the feed size can be processed by different types or different models. If the feed size is not suitable, the discharge quality will not be up to standard. For example, when the feed size is When the 100mm is reduced to 50mm, the needle-like content in the finished material is reduced by 38%, so the feed size should meet the requirements of the production equipment;
Reason three, cyclic load
The working process of the crusher is carried out in a closed loop. The discharge opening is adjusted to increase the load in the circulation. The shape of the stone will become better. During the whole process, the wear of the equipment in the system will increase due to the increased cyclic load. Increase, but when the discharge opening is adjusted, the load of the main crushing motor can be reduced, and the grain shape of the finished product becomes good. Therefore, in the production, the adjustment of the cyclic load is very important;
Reason four, open circuit and closed circuit cycle
In the production of crusher, the cycle is divided into road circulation and closed circuit circulation. The former is called first sieve and then broken. The latter is called first crushed and sieved. The first sieve and crushed means that the first crushed material passes through the finished sieve. After sieving, it enters the secondary crushing feed port to be crushed, so that the output of the finished material increases, and the needle-like content also increases. The first crushed and sieved means that all the first-stage crushed materials are fed into the secondary crusher feed port. After the re-breaking, the product is sieved into the finished product. The whole system is a closed system. There is no broken material loss and the circulation load is large, but the product has good grain shape. In the actual production of the crusher, it can be produced according to the production requirements. The choice of open circuit or closed circuit;
