Do you know what is the reason why the crusher is not up to standard? Let's take a look at it. The crushing ratio

refers to the ratio of the particle size of the imported material to the finished product after crushing. The larger the ratio, the larger the crushing ratio, and vice versa. For the crusher production process, the larger the crushing ratio, the higher the needle flake content, so in production, the adjustment of the crushing ratio is to ensure the weight of the discharged material. To take measures, of course, the crushing ratio is too small is not feasible, which will cause the reduction of the overall system output, increase the internal circulation, making the crusher wear increased, so the choice of crushing ratio needs appropriate;

reason 2, feed size

for crushers, different types or different models can be processed. Feed size is different, if the feed size is not appropriate, it will also cause the quality of the discharged material is not up to standard, for example, when the feed size is reduced from 100 mm to 50 mm, the needle flake content in the finished product is reduced by 38%, so the feed size must meet the requirements of production equipment; Reason 3,

, cycle load 88811; 1. The working process of the crusher is carried out in a closed-circuit cycle. By adjusting the discharge port and increasing the load in the cycle, the grain shape of the stone will be better. In the whole process, the wear and tear of the equipment in the system will be increased due to the increase of the cyclic load. But when the discharge port is increased, the load of the main crusher motor will be reduced and the grain shape of the finished product will be changed. Good, therefore, in production, the adjustment of cyclic load is very important;

reason 4, open and closed cycle

in the production of crushers, cycle separation cycle and closed cycle, the former is called first screening and then crushing, the latter is called first crushing and then screening, first screening and then crushing refers to the crusher after the first crushing of the material into the first. Screening and then into the secondary crushing inlet for crushing, so that the output of finished materials increased, the content of needle flakes also increased, first crushing and then screening refers to the first crushing all the materials into the secondary crusher inlet, re-breaking and then into the finished product screening, the entire system is a closed system, no crushing material. In the actual production of crusher, the choice of Open-Circuit or closed-circuit cycle can be made according to the demand of production;

or more is the reason that the crusher discharges not up to the standard, hope to help everyone. Eight hundred and eighty-eight thousand one hundred and eleven
