In the crushing process in the chemical, pharmaceutical, food,
rubber, wood and other industries, due to the different original
shapes of the materials, it is impossible to complete the crushing
process at one time for many materials, and often need to go
through coarse crushing, fine crushing, and ultra-fine crushing.
Waiting for the process. According to this situation, we
comprehensively analyzed the characteristics of various raw
materials and the existing crushing equipment, and carefully
developed the WS -type universal coarse crusher.
The machine has the advantages of simple structure, small size and
reasonable, convenient operation, low power consumption, good
crushing effect, uniform particles, etc. It is an ideal equipment
for coarse crushing, and it is ready for ultra-fine crushing.
This machine is suitable for pharmaceutical, chemical, food,
rubber, wood and other industries. It is a supporting equipment for
the pre - process of micro-grinding processing. It is not
restricted by the viscosity, hardness, softness and fiber of the
material, and can have a good pulverizing effect on any material.
The machine can also pulverize Chinese herbal medicine rhizomes,
corn stalks and Forage with a certain amount of moisture.
The coarse crusher has a horizontal crushing structure. The
material enters the crushing chamber from the feed hopper, and is
crushed by the impact and shear of the rotating knife and the fixed
knife. The material automatically flows to the outlet under the
action of the rotating centrifugal force. The machine is designed
according to the "GMP" standard. The whole machine is made of
stainless steel. It has simple structure, easy cleaning and low
noise. It is the most ideal equipment among the coarse crushers at

VI. installation, debugging and use
1. After unpacking, carefully check whether the equipment is
damaged during transportation.
2. Check whether there are any overly hard debris in the crushing
3. Check whether the fastening screws are loose, adjust the
distance between the movable knife and the fixed knife according to
the required particle size, and select the corresponding screen.
4. Turn on, start the motor to confirm the direction of rotation,
no noise, that is, feed from the feed port for processing and
5. When the production is normal, the machine will run normally
after five minutes of trial operation.
6. During the production process, if you need to replace the
screen, just unscrew the fixing screw of the discharge hopper, then
turn the discharge hopper back, unscrew the fixing screw of the
fixed knife, and take out the screen from under the fixed knife. .
VII: matters needing attention and maintenance
1. The material should not contain excessively hard debris such as
metal. Once it enters the crushing chamber, it will cause serious
damage to the cutter.
2. The steering of the motor complies with the required steering.
3. During the production process, you should always pay attention
to the noise of the crushing chamber. If there is an abnormal
situation, it should be shut down immediately for inspection. You
can continue working after troubleshooting.
4. Always pay attention to the abrasion of the cutters, and perform
tough-grinding exchanges too severely. The abrasion of the cutters
will have a greater impact on the output of crushed materials.
5. If the discharge port has fine particles and the discharge is
too slow, check whether the screen is blocked and clear it
