Introduction
HLPMF series crusher is a kind of new fine crusher invented by our
company with advantages of high efficiency, energy conservation and
environmental protection, intelligent, etc. Mainly suitable
for materials of the compressive strength value≤*0Mpa, particle
size ≤*0mm, such as coal, coal gangue, slag, carbon, etc. It can
directly break materials to 8 mm below (more than *0%). It has the
advantages of great capacity of crushing, small unit energy
consumption and wide application. Mainly used in electric power,
mining, coal chemical industry and other industrial department. It
is one of the best choices for crushing coal
for circulating fluidized bed boiler in power plant,
pulverized coal furnace, coking plant, iron-works, etc.
Operating
Principle
Two motors drive rollers of the first and second level in the
opposite direction. All teeth are the same. When materials comes
into the first crushing level by the distributor. Interlaced teeth
crush the materials from *0mm to *5mm and below. Then, materials
come into the second crushing level for further crushing from *5mm
to 8mm and below. The characteristics of the ore class material are
that generally the compressive strength is higher than the tensile
shear strength, thus, the shear tensile broken way is easier and
more energy is saved than the extrusion way. At the same time, the
material itself in the presence of lattice defects and micro crack
causes that different directions resistance broken ability is not
identical. If we can find out the most fragile directions of
crushing, the energy consumption needed for crushing will be
lower.
Main
Features 1. Single
crusher still has high output and the size is even. The size can be
arbitrary adjustable in the range of 8 to *5mm.
2. Air eddy offsets each other,
meanwhile, the leeway of the feeding and discharging hoppers is
approximately equal, which leads to no dust rising. Theres no need
for installing special dust removal equipment.
3. The adopting of a special
kinematic principle makes the crusher no sticks and stop-up and no
particular moisture requirement of the materials.
4. The toothed plate is forked tail
type which adopts sliding lockers to fasten the plate and achieves
easy removal of it.
5. The design takes fully advantages
of pull crushing theory and kinetic energy principle to reduce idle
work. Thus, its energy assumption is *0%**0% of same types ring
hammer crusher.
6. Change lubricating oil
automatically to protect the bearing and prolong its usage
life.
7. New escaping structure of the
pull crusher makes use of lever principle to increase range springs
stiffness and extend range spring group so that escaping distance
of single side reaches ****0mm, ability of passing through hard
things for the crusher has improved and displacement adjusting
becomes convenient.
8. Each toothed roller's vibration
frequency is different, but they cancel each other. Vibration and
noise greatly reduce (without damping platform), and live load is
1.3 times of dead load with small impact on the building.
9. Equipped with special open device, the first
and second door can be opened convenient. It is easy to remove
quick-wear parts.
