Introduction about Coal Crusher Coalcrusher have present in the
mining industry since the man needed to obtain energy sources.
The equipment employed in concentrate and recovery coal has
suffered some changes and must be mentioned that each piece of
separation equipment used in coal recovery has a specific range
of applicability in terms of particle size. Consequently,
determination of particle size and techniques for its control
are very interesting parameters to be considered at the moment
of selecting any equipment. Now, there are various crushers and
the crushers can be classified into extrusion type, impact type,
shear type according to the main crushing force. Extrusion type
crushing machine mainly comprises jaw crusher, rotary crusher,
cone crusher, roll crusher and so on. Its working principle is:
materials crushed by the extrusion, splitting and bending force
between the crushing mechanism fixed tooth plate and the movable
tooth plate. This kind of crusher mixedly crush materials in the
crushing cavi
