Description
A dewatering screen is a device that quickly separates the moisture in the mixture from the solids. It is used in coal preparation, mineral processing, power generation, sugar, salt, and other industrial departments for dry-wet screening, dewatering, desliming, and desliming of medium and fine-grained materials. The dewatering screen structure consists of a screen box, an exciter, a support system, and a motor. The screen material is polyurethane, which has high dehydration efficiency and long service life, and the screen holes are not easily blocked.
The function of the dewatering screen is to improve product dryness, reduce energy consumption, and improve production efficiency. Dewatering screens are widely used in mining, metallurgy, environmental protection, and other fields, such as:
- The coal industry:Used in coal slurry dehydration, wet coal drying, and other fields.
- Mining industry:Used in mineral, sand, metallurgical, and other fields.
- Environmental protection industry:Used in solid-liquid separation, sludge dehydration, and other fields.
Advantages
- High wear-resistant screen plate, long life, modular assembly design, easy replacement, cost savings, and screen mesh size, can be selected according to requirements.
- V-screen design, screen surface slope dewatering screen with low water, high efficiency, large capacity per unit area.
- Waterproof proper frequency dedicated motor, double motor-driven self-synchronization technology , to achieve of dewatering.
- Small investment,simple process and small area.
- The dehydration effect is good,safe and reliable.
Principle
The dewatering screen adopts dual-motor self-synchronization technology, a universal eccentric block, and an adjustable amplitude vibrator. The screen mainly comprises a screen box, vibrator, support system, and motor. Two vibrators that are not connected run in synchronous and reverse directions. The centrifugal forces generated by the two sets of eccentric masses are superimposed along the vibration direction, and the reverse centrifugal force is offset, thereby forming a single exciting vibration along the vibration direction, making the screen box reciprocate naturally linear motion.
