subject: What Impinges On The Compound Crusher [print this page] Compound crusher is widely used in the field of various minerals, cement, refractory material, bauxite clinker, silicon carbide, glass raw material etc. that belong to dead-hard or ultra hard materials applied in secondary and tertiary crushing. Our combination crushers are ideally suitable for primary and secondary crushing, with low power consumption and easy maintenance. Every feature of these machines has been carefully designed to provide superior quality and performance. Compound crusher has a bigger reduction ratio that the biggest one can reach the degree that discharging granularity can be regulated arbitrarily unaffected by the plate hammers and liners abrasion. No-diagrid design, high crushing water content, not easy to be blocked when materials possess big mud content; adoption of elastic adjusting mechanism enables the uncrushing materials to discharge automatically that avoid the damage to the equipment; placed horizontally, long lifespan, able to crush high-temperature materials(cement clinker).
1. The composition of the materials to be crushed. The more the sand content and powder content of the materials, the easier for the materials to adhere to the normal input of the conveyor in the process of the delivery of material. The workload of the crusher increases, however, the output does not. Therefore, the workers should understand the fineness of the raw materials and reduce the sand content and powder content of the materials if necessary.
2. The nature of the materials, including the hardness, the composition, the viscosity and the moisture content of the raw materials, the particle size and fineness the products require, and so on. The higher the hardness of the raw materials, the more difficult of the crushing work. The crushing ability lowers and the crushing work progress slows down. The longer the raw materials stay inside the machine, the higher the wear and tear of equipment. Therefore, relatively speaking, the crushing efficiency of materials with low hardness is higher than the materials with great hardness, with the yield of the former is also higher. In the crushing production line, if the production materials are uncertain, the workers should try to choose those raw materials with middle hardness, which can improve the crushing progress and product yield in an easier way.
3. The moister content of the materials also affects the productivity of the compound crusher. When the materials contain large amount of water, they are easy to form the adhesion phenomenon in the crusher, causing obstruction in the process of feeding and nesting and reducing the crushing capacity. As for the materials with high moister content, the workers could take certain measures to control the water content.
All these above factors influence its working efficiency.
Materials fall vertically from the machine into high-speed rotating impeller, impacting and smashing with those scattered around in the form of an umbrella shape. After mutual impact, they would impact, rub and smash with each other under eddy current formed by the materials between impeller and chassis and then discharged directly from the lower part. A closed multi-circulation has been formed and the screening equipment controls it to get to the demanded granularity of the finished products.
