When choosing a crusher, it is necessary to fully consider the type, hardness, humidity, specification, particle size of incoming and outgoing materials, output and construction site of the crushed material. The hardness of the material. Different types of materials have different hardness, the greater the hardness, the more difficult it is to crush. To crush hard or medium-hard ores, select jaw crushers as primary crushing equipment. For crushing medium-hard or soft ores, select cone or impact crushers. The specification of the material. If the size of the material is relatively large, the jaw crusher will be ideal choice. When the size of the stone is relatively small, it is necessary to use other crushing equipment for combination, such as using a jaw crusher anda cone or impact crusher. Humidity of the material. When choosing a crusher, pay attention to the moisture content of the material. A large moisture content will lead to an increase in the humidity of the material, thereby increasing the viscosity of the material, reducing the discharge speed of the material, and reducing the production line rate. In severe cases, it may cause blockage of the ore discharge port, cause material blockage of the crusher, and affect the normal operation of the sand making production line. The degree of cleavage development of ore. The degree of ore cleavage development will affect the production capacity of the crushermachine. Because the ore is broken along the cleavage plane when it is broken, the production efficiency of the crusher will be higher for the ore with well-developed cleavage. The granularity of incoming and outgoing materials. One of the most important factors in choosing the model and grade of crushing equipment is the particle size of the incoming and outgoing materials. If the input particle size is large, but the output particle size is small, it is necessary to use two or more stages of crushing. Production requirements. The output requirement of the production line is an important indicator to determine the crushing equipment. If the production output is required to be large, the size and type of crushing machinerequired will be larger, and the capital investment and output of the production line will increase. Construction Site. The size of the construction site, such as the production line site, and the specific location of the crushing equipment installation are the most direct factors affecting the selection of crusher equipment.
