Impurity Removal System
Process Overview:
The primary objective of chemical refining is to remove impurities and contaminants from materials, which necessitates physical treatment. This typically involves processes such as grinding, screening, centrifugation and volatilization. During grinding, impurities are pulverized to increase surface area, thereby accelerating subsequent processing steps. Screening selectively removes oversized impurity particles, while centrifugation and volatilization separate solid or liquid contaminants from the raw material, resulting in purified products.

Screening Machine
The rotary screener is widely used in industries such as food, chemicals, artistic textiles and pharmaceuticals. Both small bakeries and industrial-scale ones utilize the screening machine at grain silo or bagging stations for screening. The equipment can be used as a part of the pneumatic conveying system for fully enclosed operations.

Vibrating Screen
The equipment consists of a hopper, oscillation chamber, coupling and motor. Inside the oscillation chamber are an eccentric wheel, rubber flexible connectors, main shaft and bearings. The adjustable eccentric counterweight, driven by the motor, transmits force to the main shaft’s centerline, generating centrifugal force under an unbalanced state. This alters the material’s intensity, creating an orbital vortex motion within the screen. The amplitude of the counterweight regulator can be adjusted based on different materials and screen meshes. The entire machine features a compact structure, small footprint, dust-free operation, low noise, high-quality output, low energy consumption and easy mobility for maintenance.

Scraper Filter
The scraper filter is an innovative and high-efficiency filtration system that automatically removes particulate contaminants from the inner surface of filter elements through mechanical scraping action, enabling continuous online filtration operation.
