Automatic Dosing Mixing System and Pneumatic Conveying System for PVC Cable Extruder Line

Raw materials and additives → automatic batching → high-speed mixing → internal mixing → double-roll open refining → water cooling → drying → pelletizing → screening & magnetic separation → precise dosing → automatic packaging.

This process ensures excellent plasticization, uniform dispersion of additives, and superior pellet quality.

Raw materials and additives → automatic batching → high-speed mixing → cooling mixing → single-screw extrusion → hot-face cutting → air cooling → screening & magnetic separation → precise dosing → automatic packaging.

Designed for continuous production, this solution offers high output, stable operation, and consistent granule quality.

1. Main material weighing system

This system is inspired by advanced Japanese and German technologies and introduced by our company. Our R&D team has independently developed the Smart High-Precision Chemical Batching System, designed for accurate dosing and batching of granular, powder, and flake materials. It is widely used in industries suchs as rubber, cable polymers, silicone, friction materials, plastics, and pigments.

The system supports multiple feeding methods, including electromagnetic vibrators, single or double screw feeders, belt conveyors, self-cleaning screw feeders, vibrating screw feeders, and continuous stepless speed-controlled smart devices. Multiple electronic scales operate independently to meet diverse user requirements, enabling automatic control and management of the material weighing and batching process while ensuring consistent and precise batching accuracy. The system also features comprehensive environmental protection measures and fully automated bag-making and material-handling equipment.
