factors affecting the crushing efficiency of the crusher

During the production process of rock crusher, the crushing efficiency is not only affected by its performance, but also affected by several other factors. Knowing the factors affect stone crusher crushing efficiency can help investors improve the production rate. In the following part, we focus on factors affect the production efficiency of rock crusher.

Different types of crushers have different working principles. The physical properties like hardness and fragility of raw material will all affect the crushing efficiency of a stone crusher. If we adopt the proper type of crusher to process proper raw material, the crushing efficiency of the crusher is high. On the contrary, while being used to crush raw materials with high hardness or viscous material, the crushing efficiency will reduce.

If the moisture content of raw material is too high, it will also reduce the crushing efficiency of a rock crusher. This is because during the crushing process, too wet raw materials will adhere to the crushing cavity and other parts, reducing the volume of the crushing cavity and the crushing efficiency.

During the working process of stone crusher, crushing cavity directly contact raw materials, making it the main wear-resistant part in the crusher. In different crushers, the crushing cavities are formed by different parts. In jaw crusher, the crushing cavity is formed by fixed jaw plate and movable jaw plate and in cone crusher, the crushing cavity is formed by concave and mantle.

If the crushing cavity is seriously damaged, the crushing force will reduce, which will lead to the reduction of crushing efficiency. Besides, the abrasion of the crushing cavity will also make the final products size increases, affecting the crushing effect.

The production efficiency of the rock crusher has great influence on the efficiency of the whole crushing plant. Operators should pay attention to the above 4 factors during the working process of rock crusher and solve the problems in time in order to improve the production efficiency.

During the using process, if the worker operates and maintains the crusher according to correct standards, it will have great significance in normal production, output, quality, service life, working efficiency and the prevention of accidents, etc.

At present, the common cone crushers are mainly the single toggle cone crusher and compound cone crusher (Symons cone crusher). Although both types of cone crushers are totally different, they have the same operation procedure.

The operation procedure of cone crusher can be divided into four stages: before the start, at start-up, at run time and turning-off time. All conditions should be paid attention in each stage, and the potential problems can be found and solved timely and the service time can be prolonged.

Turn on the lubricating oil pump to run for three to five minutes. After everything runs well, turn on the crusher as required. After the crusher idles for one to two minutes, confirm that all things are well, and feed the rocks or stones.

During the crushing process, there is a great impact on the concave which makes the filled zinc layer be out of shape. Therefore, the U-type bolt should be tightened frequently to make the concave fix and avoid concave from deformation.

The mantle is fixed by the upper bolt of the main shaft. The looseness of the bolt can make the mantle unstable, even the filled layer may fall off to cause downtime. Hence, the bolts should be often checked and fixed to avoid looseness.

The spherical bearing should be installed in the borehole of crusher closely. After a long period of working, the tightness of crusher' parts can be broken. The tightness of spherical bearing must be checked frequently, and the oil gallery of the spherical bearing should be kept clean.

Water seal is the equipment for preventing crusher from dust, which is very important to the normal operation of cone crusher. Therefore, daily maintenance and checking its integrality are very necessary.

Through the study of this article, you must have a deeper understanding of the operation and maintenance of the cone crusher. In the case of the above-mentioned failure of the crusher, the problem is analyzed and solved by referring to the method given in this article.
