Description

The specifications of the grinding disc of the plastic pulverizer can be divided into separate or whole-piece grinding discs;
The material of the grinding disc of the plastic mill is made of alloy steel with HRC up to 63, such as SKD-11; D2; DC53;
Plastic pulverizer disc blades can be plated with TiAlN or W to increase hardness and wear resistance.

In the grinding disc mill, there are two grinding discs in the grinding chamber. The opposite surfaces of the grinding discs are covered with grinding teeth. The moving disc is driven by the motor to rotate at a high speed, and the static disc is stationary to cause relative motion, and large particles are sheared inside. Cut and centrifugal impact to complete the refinement.
A1: The moving plate and the static plate can be completely parallel, stepped, or partially inclined;
The grinding teeth on the moving disc are sheared relative to the grinding teeth on the stationary disc under high-speed rotation. Entering, it is thrown to the edge of the grinding disc by centrifugal force, and it is cut and thinned. Since the bearing on which the moving disc moves at high speed is not completely unbiased, axial runout will occur, so the gap between the dynamic and static grinding discs should not be too small, otherwise there will be a mechanical accident where the two discs collide and damage the grinding teeth, especially in the Run under empty machine without plastic. Because of the existence of the reaction, the entry of coarse plastic particles will cause the separation force between the moving and static disks.
The grinding chamber is the most important part. At present, the shape of the grinding chamber of the grinding disc mill is rectangular, circular and hexagonal.

A2: The grinding tooth is the core part of the grinding disc, and the grinding tooth has the following structures. According to the number of working faces, it is divided into single working face, double working face and 3 working face;

A2-1: Grinding gear distribution on a single working surface, with scattering shape, straight line uniform distribution, and grid shape;
For a grinding tooth, its side view can be pagoda type, right angle type, sawtooth type;

A3: The key factors of the grinding disc of the grinding disc mill are the thickness of the teeth, the running accuracy of the grinding disc, and the hardness of the grinding material. The coarse teeth are suitable for grinding coarse powder (20 mesh), with long service life and convenient processing; Harder plastic, wide processing range and long service life, mainly depends on metal materials and heat treatment; the grinding disc has high running precision, and the particle size distribution of the ground powder is uniform;
