Peripheral drive thickener is a new type of thickener developed by our company by introducing foreign technology. It combines the advantages of traditional central drive thickener and peripheral drive thickener, and is an updated product of traditional thickener. It is widely used to treat thick and heavy industrial slurry, such as coal, metal dressing water, metallurgical wastewater, chemical slurry, etc.
Application of Peripheral transmission thickener
Used for：Mine Ore dressing slurry tailings, metallurgical wastewater, chemical slurry, coal slurry

More Introduction
Main features
1. The central deep feeding, horizontal flow sedimentation, reduces the settling height, reduces the kinetic energy of solid particles. In addition, the rake frame is a connecting rod structure, which reduces the interference of particle sedimentation, accelerates the concentration and deposition process, and the processing capacity can be increased by 30-50%. If flocculants are added, the processing capacity can be greatly improved.
2. The peripheral drive device driving the bridge rotation has large torque, high strength and stepless speed regulation to meet the requirements of different production conditions; Rack or rubber wheel drive can be selected according to the site working conditions.
3. The three angles at the bottom of the tank facilitate the scraping and collection of settling materials, improve the underflow concentration, and have good civil engineering economy.
4. It can be equipped with a central mixing device to prevent the materials in the central cone pit from hardening and damaging the equipment.
5. Lift the rake hydraulically in sections. The lifting action is reliable, and the rake can be lifted above the liquid level to facilitate equipment maintenance.
6. The machine can be operated automatically and manually to clean the pool after a long shutdown or in case of failure, without waterproof and affecting production.
7. The whole machine adopts PLC program control to realize overload alarm indication, automatically control rake lifting and rake lowering (use sensors to detect operating pressure), and can be controlled automatically, manually or remotely.
8. The power collecting device is fully sealed, which is reliable, safe and has a long service life.
9. The main torque bearing parts are made of high-strength materials to improve the mechanical strength and avoid equipment operation failures.
10. The main supporting parts are imported *, joint venture or domestic brand products with reliable quality.
11. The national production and manufacturing standards for this type of thickener are drafted and formulated by our company.
