A high-efficient and environmental crushing equipment can improve the efficiency of the whole production line and increase the income of an enterprise. The following factors can help users choose suitable crusher. The basic principles of crusher selection.
Factors to consider when choosing a crusher
When selecting the crusher, the type, hardness, inlet and outlet particle size, and output and construction site of the crushed material should be fully considered.
The hardness of the material
Different types of materials have different hardnesses. In general, the greater the hardness, the higher the fracture difficulty coefficient. For crushing hard or medium hard stone materials, the jaw crushing equipment should be selected as the first-stage crushing equipment. When crushing medium hard or soft stone, the cone, counterattack or hammer crusher can be directly used.
Material specifications
If the material size is large, the jaw crusher can be used as the first-stage crushing; when the stone size is small and needs to be composed of a certain grade of stone, it is necessary to use the combined crushing and screening equipment, such as the jaw crusher. Combined crushing equipment consisting of cone or counterattack and hammer crusher.
Material humidity
The water content of the material will also affect the choice of the crusher. When the water content is too large, the fine material will agglomerate or stick to the coarse material due to the increase of humidity, thereby increasing the viscosity of the material and reducing the rate of discharge. Productivity has declined. In severe cases, it may even cause blockage of the discharge port, which affects the normal production.
The degree of ore hair removal
The degree of hair removal of the ore directly affects the productivity of the crusher. Since the ore is easily broken along the cleavage plane when it is broken, the ore of the haircut is broken, and the productivity of the crusher is correspondingly higher than that of the compacted ore.
Cost and quality of wear parts:
The Cost and Quality of Parts Can Vary: this can be due to a number of factors such as the material used in the parts including manganese, steel, chrome or ceramic, if they are genuine parts, and the quality of manufacture.
Ease of maintenance:
Some Jaw Crushers have Removable Engines: which can ensure that when located remotely from the crushing plant it will reduce dust and vibration levels, as well as facilitate easy maintenance access.
Some Jaws Have a Reversible Jaw Drive: that allows material like asphalt to be 'fluffed' and in the case of oversized or sticky material; quickly unblock the unit and continue crushing. Both of these features assist in managing WHS.
