Guidance and Instructions for New Mining Crushers Users

In the global mining industry, commonly used crushing machines include jaw crusher, hammer crusher and cone crusher, etc.   Each kind of crushers haw their own competitive characteristics and advantages.   They cover various crushing levels, which makes the crushing machinery industry of rapid development.

Used for raw materials of coarse jaw crusher mainly, in preparation for the secondary crushing.   Jaw crusher is suitable for crushing hard materials or hardness of the raw material, not suitable for broken soft hardness of raw material, the requirement for the moisture content of material should be no greater than 10%, the raw material moisture content is exorbitant, jaw plate materials, impact crushing efficiency.   In particular, when using jaw crusher should pay attention to two points: one is in front of the material into the crusher, should advance to sieve out powder particles in the material, the use efficiency of crusher abilities has great significance, because these powders can fill jaw edges between the slot, make the effective height of the rib reduce, jaw broken out between the material only with stress.   It is another point that should be paid attention to the jaw crusher feed should ensure as far as possible along the whole inlet on the width of the material, to ensure uniform feeding, special feeder can be used when necessary.

Hammer crusher according to the structure points are vertical, horizontal, such as single rotor and dual rotor type, discharging place most equipped with fixed screen, the user can according to your own needs to choose suitable aperture sieve to control the discharging granularity.   Fighter has this kind of crusher is suitable for crushing brittle materials, such as coal, shale, etc., for a very hard material or adhesive material is not applicable, list of rotor broken than normal in 10 to 15, double rotor can be up to 20 a, it is very strict with the moisture content of raw materials, should not be commonly more than 8%,...
