Introduction

Hammer mill can grind sawdust and other materials. It has special design for fiber raw materials, moist or oily materials and fine grinding. This kind of hammer mill, is welded by thicken plates. The interior part of grinding chamber and the parts contacted with materials are all made of wearable and replaceable components and double wear-resisting plate. Rotors of motor and hammer mill are installed on the same heavy base. Using straight coupling transmission, the rotor is checked by the dynamic balance test, and can work clockwise or anti-clockwise. and hammer piece for symmetry. This machine is simple in structure, durable in fastening, safe and reliable, easy to install, simple in operation, small in vibration and high in productivity. The hammer plates are arranged symmetrically. This machine is simple in structure, durable in fastening, safe and reliable, easy to install, simple in operation, small in vibration and high in productivity.

Note: the above indicators meet the following conditions: raw material varieties, wood chips, moisture content shall not be more than 13%, and the capacity shall not be less than 0.72t /m3. The hole diameter of the screen plate of the hammer mill is Φ 10, and the hole ratio is not less than 33%. The hole diameter/ ratio of screen plate affects the output.


Vulnerable Parts List

Base: The heavy base plays the role of connecting and supporting various parts of the hammer mill to reduce vibration, increase reliability and prolong service life.The ground material is discharged from the lower outlet of the base.

Rotor: It is composed of main shaft, hammer frame plate, pin shaft, hammer pieces, bearing, bearing seat and other parts, and is the main moving parts of the hammer mill. The rotor rotates fast, so the rotor must be checked by dynamic balance test in the case of no hammer.

Operation door: it is necessary to open the operation door when changing the screen plate or hammer pieces. The special pressure screen mechanism makes it very convenient to change the screen plate in short time.

Wear-resisting Plate: The part in contact with the material in the grinding chamber is wear-resisting board. The wear-resisting plates of the superior hammer mill are all designed as replaceable parts. When the abrasion reaches a certain degree, it must be replaced in case of damage, falling off or other accidents.

Upper Casing: It connects wear-resisting plate and seals the grinding chamber with the operation door closed.

Feeding Guide Mechanism: According to the rotation of the rotor, the material enters the grinding chamber from the left or right (see figure 5).

 

The Working Process

The material to be ground is fed into the grinding chamber from the top of the feeding port through the feeder equipped with the machine, and enters the grinding chamber from the left or right through the feeding guide plate. The material is gradually ground under the impact of high-speed rotating hammer and friction of the screen plate, and is discharged from the base outlet through the screen hole under the action of centrifugal force and air flow.
