PC**0x**0 hammer mill (hammer
crusher)is mainly applied to low abrasion materials with
medium hardness and compression strength not exceed **0Mpa. Such as
coal, salt, chalk, gypsum, bricks, tiles, limestone, etc. It is
also used to crush wood chips with strong fiber structure and
tenacity, and the waste from asbestos cement to recycle asbestos
fiber, etc. In addition, hammer crusher can be not only applied in
crushing line and sand production line, but also applied instead of
cone crusher.
Performance and
features:
Hammer
crusher(hammer mill) has the advantages of high product capacity,
high crushing ratio, low power consumption, uniform products
partial size, simple structure, compact and light, low investment
cost, easy to management, etc. The defects are: when crushing very
hard materials, it will cause greater wear of hammer and grate and
consume more metal; it needs more maintenance time and uniform
feeding of materials; when crushing soft-moist materials, the
capacity will become significantly lower and even stop because of
material jam. In order to avoid jam, the moisture content of
materials should be less than *0%**5%.
Working
principle:
Hammer
crusher(hammer mill) mainly consists of frame, rotor, trapezoidal
iron plate, bar grate, etc. And the frame consists of the upper
part and the lower part, which are made of welded cut armor plate,
while other parts are connected into one by bolts. High manganese
steel liners are mounted in the frame and can be replaced after
wearing out.
There are several sets of hammers equipped on
the main shaft of the hammer crusher in regular distribution. They
constitute the rotor with dial and hammer shaft. Driven by the
motor and V-belt, the main shaft rotate with rotors. And the rotors
spread to the surrounding extensions under the centrifugal force
brought from rotating. So when big materials fall into the crushing
cavity of hammer crusher, they will be broken into pieces by high
speed rotors. The qualified materials after crushing will be
discharged from the gap of grate at the bottom, while those
unqualified ones will still stay in the crushing part and then
discharged when they reach the acceptable size after repeated
actions of hammers and trapezoidal iron plates.
