MF-800 Plastic disc PET pulverizing milling machine with vacuum loader

PET pulverizing machine is mainly used to grind PET (polyethylene terephthalate) materials into powder. For example: PET grinding machine can grind waste plastics, such as mineral water bottles, carbonated drink bottles, white medicine bottles, etc., into powders of different specifications, which can be used for the production of recycled plastic products, such as plastic bags, plastic bottles, plastic containers, etc. . At the same time, it is widely used in packaging, fiber and other fields.



PET pulverizing machine mainly consists of the following parts:
A1. Feeding device: used to feed materials into the grinding chamber. Common feeding devices include vibrating feeders and screw feeders. These devices usually have continuous and stable characteristics and can ensure uniform feeding of materials.
A2. Grinding chamber: The grinding chamber is the core part of the grinding mill, used to accommodate abrasives and materials. The interior of the grinding chamber is usually composed of grinding discs, grinding rollers and grinding rings, and has a certain structure and shape.
A3. Grinding disc: This is the main component in the grinding chamber for grinding materials. Grinding discs are usually made of high-hardness, wear-resistant materials that can withstand the friction and impact of larger abrasives and materials. The shape and size of the grinding disc can be selected and adjusted according to different materials and grinding requirements.
A4. Powder discharge device: The powder discharge device is used to discharge the ground powder from the grinding cavity. The powder discharge device usually consists of two methods: pneumatic powder discharge and mechanical powder discharge. Pneumatic powder discharge blows the powder out by wind force, while mechanical powder discharge pushes the powder out through mechanical devices.
A5. Main machine: The main machine is the driving part of the grinding mill, usually consisting of a motor and a transmission device.
A6. Frame: The frame is the supporting part of the grinding mill. It usually adopts a combined structure of upper steel plate welding and lower cast iron bracket to make the grinding stress self-sustaining, which is beneficial to maintaining stable rolling distance and reducing noise.
A7. Electrical control system: used to control the operation of the grinding mill, including start, stop, speed adjustment and other functions.
