With the development of PVC extrusion processing in the direction of scale, advanced material pretreatment system is essential, which is the primary condition to ensure the realization of high yield, high quality and low price. This paper introduces the technology and characteristics of PVC automatic mixing system in detail.

In the PVC extrusion processing industry, the traditional PVC mixing automatic system methods are: hot mixing, cold mixing, manual mixing and transportation. With the continuous expansion of enterprise production scale, this method can no longer meet the needs of mass production.

At present, a better solution is to take the computer-controlled automatic batching system as the core, supplemented by pneumatic conveying, and combined with hot and cold mixers to form a complete PVC batching and mixing production line. Compared with traditional methods, the new scheme has many obvious advantages, including:

1. The automatic batching system controlled by computer improves the batching accuracy and solves the problems of the complexity of manual batching, material loss and chemical hazard to operators.

2. The efficient pneumatic conveying system has replaced the heavy labor in the process of handling a large number of materials and improved the production efficiency.

3. The material handling process is completely carried out in closed pipes, avoiding the pollution of dust to the workshop environment and the harm to workers.

4. The material preparation and processing process is more centralized and efficient, and the output is higher, which can completely meet the needs of mass production.
