Six Factors to Choose the Crusher

The crushing of materials is an indispensable technological process in the production of products in many industries, such as metallurgy, mining, building materials, chemicals, ceramics, etc. Due to the difference in the physical properties and structure of the materials, the selection of the crusher machine should also analyze in detail.

Based on the consideration of product performance, crushing could divide into coarse crushing, medium crushing, fine crushing, etc. And various types of crushing equipment have been prepared accordingly.

Common crusher machines

In daily production, we use the most crushers: jaw crusher, cone crusher, vertical shaft impact crusher (also known as sand making machine), impact crusher, hammer crusher, etc. There are many crushing equipment on the market. Choosing a suitable crushing equipment can not only reduce the crushing time and reduce the waste of materials.

What factors should be considered when choosing a crusher?

The reasonable choice of crushing equipment can help users solve many problems. But when choosing a crushing equipment, one reason we should consider, but multiple considerations. Crushing equipment mainly affect by the type and hardness of materials, water content, degree of cleavage, and particle size of incoming and outgoing materials. In addition, the construction site and output should also be considered.

Material type and hardness

Material type and hardness are an important principle for choosing a crusher. The hardness of different materials is not the same, usually Mohs hardness use to indicate the hardness of the material. The Mohs hardness is divided into 10 levels. The greater the Mohs hardness number, the harder the ore and the greater the difficulty of crushing, and vice versa.

The water content of the material

Material moisture content will also affect the choice of crusher. When the water content is too large, the fine-grained material will agglomerate or stick to the coarse-grained material due to the increase in humidity, thereby increasing the viscosity of the material. This will reduce the rate of material discharge and reduce productivity. In severe cases, it may even cause blockage of the discharge port, affecting the normal production.

The degree of cleavage of the material

The degree of cleavage of the ore also directly affects the productivity of the crusher. When the ore material is broken, it is easy to break along the cleavage surface. Therefore, the production rate of the crusher is much higher than that of the ore with compact structure.

Inlet and outlet particle size

The granularity of incoming and outgoing materials is used to determine the type and level of crushing equipment required.

If the content of coarse particles (greater than the size of the discharge port) in the crushed material is high or the ratio of the largest block to the width of the ore is large, the crusher needs to achieve a large crushing ratio, so the productivity reduce. When the content of fine particles in the crushed material is large or the ratio of the largest block of the ore feed to the width of the ore feed is small, the crushing ratio to achieve is small. So its productivity is increased accordingly.

Construction site

The size of the construction site is also one of the factors that people consider when choosing a crusher. In addition, the placement of crushing equipment also affects the choice of crusher.

Output of the crusher

The output is also an important indicator that determines the selection of crushing equipment. The conventional understanding is that the higher the output requirement, the larger the size of the crushing equipment required. And the corresponding input and output will increase.
