How to prevent plough mixer material residue?

Here are some ways to prevent plough mixer material residue:

1. Choose the right equipment design

Reasonable barrel structure: Choose a plough mixer with a smooth barrel interior and no dead corners. For example, an elliptical or round barrel can be used to avoid material accumulation in the corners of a square barrel. At the same time, the gap between the barrel and the plow shaft should be uniform and as small as possible to prevent material from being retained here.

Optimize the discharge port design: The size and shape of the discharge port should be designed according to the material characteristics and output to ensure smooth discharge. A large-diameter discharge port or multiple discharge ports can be used to reduce the residue of materials near the discharge port. In addition, the position of the discharge port should be set at the lowest point of the barrel so that the material can be completely discharged by gravity.

2. Correctly select and use mixing components

Appropriate plow shape and size: Choose the appropriate plow shape and size according to the characteristics of the material. For example, for sticky materials, a plow with wide blades and large angles can be used to better promote the flow of materials and reduce the adhesion of materials to the plow. At the same time, the installation angle of the plow blade should be reasonable to ensure that the material can be effectively transported to the discharge port.
Regularly check and replace the plow blade: the plow blade will gradually wear during use, and the worn plow blade may not be able to effectively push the material clean, resulting in material residue. Therefore, it is necessary to regularly check the wear of the plow blade and replace the severely worn plow blade in time.

3. Optimize the operation process
Reasonable material addition sequence: According to the characteristics and mixing requirements of the materials, a reasonable material addition sequence should be formulated. Generally speaking, a large amount of material is added first, and then a small amount of material is added, so that the material can be fully mixed during the mixing process and the material can be reduced. Adhesion to the wall of the cylinder and the plow blade is reduced.
Thorough cleaning procedure: After each mixing operation, the mixer should be cleaned in time. It can be cleaned with water, compressed air, or a special cleaning fluid to ensure that there is no material residue on the inside of the cylinder, the plow blade, and the discharge port. For materials with strong viscosity, hot water or an aqueous solution with a cleaning agent can be used for cleaning, which will have a better effect.

4. Choose the right material handling technology
Pre-treat the material: Pre-treating the material, such as drying, screening, etc., can reduce the viscosity and humidity of the material, making it easier to flow and reducing the possibility of material residue.
Adding flow aids: Adding a proper amount of flow aids to the material, such as talcum powder, magnesium stearate, etc., can improve the fluidity of the material and prevent the material from adhering to the inner wall and parts of the mixer.
