Vertical mixing machine

The friction materials of brake pads are composed of phenolic resin, mica, graphite and other raw materials, but the proportion of each raw material is different with different formulations. When we have a clear raw material formula, we need to mix more than ten kinds of materials to get the required friction materials. The vertical mixer uses the rapid rotation of the screw to lift the raw materials from the bottom of the barrel from the center to the top, and then throw them away in an umbrella shape and return to the bottom. In this way, the raw materials roll up and down in the barrel for mixing, and a large number of raw materials can be mixed evenly in a short time. The spiral circulation mixing of vertical mixer makes the raw material mixing more uniform and fast. The materials in contact with the equipment and raw materials are all made of stainless steel, which is easy to clean and avoid corrosion.

Compared with the plough rake mixer, the vertical mixer has higher working efficiency, can mix raw materials evenly in a short time, and is cheap and cost-effective. However, due to its simple mixing method, it is easy to break some fiber materials during work, thus affecting the performance of friction materials.
