Lab Scale Mixer PVC Plastic Powder Mixing Equipment Description:
The laboratory scale PVC plastic powder mixer is a small device designed specifically for laboratory testing, suitable for mixing, coloring, drying, and pre-treatment of various resins such as PE, PP, PVC, engineering plastics such as ABS, PC, and phenolic resins before molding and processing. Its core function integrates hot mixing and cold mixing: after heating and mixing, the material automatically enters the cooling mixer, synchronously discharges residual gas to avoid agglomeration, and ensures processing quality. It is an ideal equipment for plastic mixing laboratory testing.

Lab Scale Mixer PVC Plastic Powder Mixing Equipment Features:
The laboratory scale PVC plastic powder high-speed mixing unit adopts three-dimensional negative pressure mixing technology to achieve efficient and uniform dispersion of raw materials in multiple dimensions; Equipped with imported PLC intelligent control system, supporting fully automatic operation and fault self diagnosis, ensuring batch stability; The blades have undergone precision dynamic balancing treatment, resulting in stable operation and significantly improved durability of the transmission system; The combination of spiral jacket cooling structure and blind spot design results in high cooling efficiency and precise control of discharge temperature; The equipment supports modular linkage, is compatible with downstream equipment such as extruders, meets international standards and CE certification, and has a single batch processing capacity covering small-scale to pilot scale requirements, helping to shorten the research and development cycle and improve product quality.

1. The container lid and the container between the use of concave and convex double channel sealing method, compared with the traditional single channel flat seal, the sealing effect is better.
2. The spindle seal is a three-layer skeleton oil seal made of imported durable rubber with an oil injection device, which has a good sealing effect and long service life.
3. The discharge valve adopts a plunger-type material door plug. The inner surface of the door plug fits tightly with the inner wall of the container so that there is no dead zone for mixing, and the material is mixed evenly. The material door plug adopts the end seal method, the seal is reliable. The temperature measuring point is located in the container, which is in direct contact with the material, so the temperature measurement is accurate. The paddle of the cold machine adopts a large inclination paddle, forcing the material to rise along the inner wall of the container, and then back down through the cooling jacket to achieve the purpose of cooling.
4. The wall of the container is equipped with a cooling sandwich, and the cooling sandwich adopts a spiral waterway to make the cooling water flow according to the set route. Uniform cooling, fast cooling speed and good cooling effect. The container is equipped with an inverted cone-shaped inner cooling jacket, which increases the cooling area and speeds up the cooling speed.
5. The cold machine introduces foreign deceleration technology to adopt direct deceleration device, which overcomes all the shortcomings of using decelerator and makes its operation more stable. The lid of the container of the cold machine is equipped with an exhaust device, which fully excludes the gas generated by the hot mix in the cooling process and improves the quality of the products.
6. The inner wall of the container of this unit is made of stainless steel plate, which increases the service life of the equipment.
7. The electrical control system is temperature and time double control, and other components are made of products of famous enterprises to make its performance reliable and more sensitive to ensure the performance of the whole machine.
