Product Introduction

The dewatering screen is mainly used for the dewatering, desliming, and medium removal of various materials. It can be used for washed-sand processing in sand and aggregate plants, coal slime recovery in coal preparation plants, and dry tailings discharge in mineral processing plants. Accordingly, it is also known as a sand and aggregate dewatering screen, mining dewatering screen, coal slime dewatering screen, or tailings dewatering screen.

The equipment mainly consists of a screen box, vibration exciter, support system, and motor. It is driven by either dual vibration motors or exciters powered externally by two conventional motors rotating synchronously in opposite directions. This causes the screen body to perform periodic reciprocating linear motion, thereby achieving material classification and dewatering.

Performance Advantages

Screen media options include manganese steel woven wire mesh, stainless steel slotted screens, perforated screen plates, bar-type screen decks, polyurethane screen panels, cast screen plates, and more.

Tongxin dewatering screens use ultra-high-molecular-weight polyurethane screen panels, which offer excellent impact resistance, low-temperature resistance, wear resistance, chemical corrosion resistance, self-lubricating properties, and impact energy absorption. They provide outstanding impact resistance and superior wear resistance compared with materials such as PTFE, nylon, and carbon steel.

Product Features

1. 1.The screening machine is installed horizontally, while the screen deck is set at a negative inclination angle to ensure effective forced dewatering.

2. A variety of screen media options are available to meet different operating requirements.

3. The vibration frequency can be adjusted at any time through a variable frequency drive (VFD) to achieve optimal dewatering performance.

4. The dewatering screen is driven by a self-synchronized, liquid-lubricated vibration exciter. The screen frame incorporates special noise-reducing materials and is connected with high-strength bolts, ensuring reliable operation while reducing operating noise.

5. 5.The feed section of the dewatering screen is equipped with a curved screen deck to improve dewatering efficiency. A feed box is also provided to ensure uniform distribution of material across the screen surface.

Dewatering screens can be classified into the following types according to their applications

1. Coal Slime Dewatering Screen

The coal slime dewatering screen is specifically designed for desliming, medium removal, and dewatering in coal preparation plants. It can be used to recover coal slime with a particle size of less than 9 mm and is specifically designed for coal slime dewatering applications. It is widely used for coal slime recovery, coarse-particle removal prior to filter pressing and filtration, as well as the dewatering and recovery of other fine materials.

2. Sand and Aggregate Dewatering Screen

The sand and aggregate dewatering screen is mainly used for washed-sand processing. It is commonly integrated with sand washing machines in wet sand production lines but can also operate independently. After being washed by a sand washing machine, the material undergoes hydraulic classification, desliming, and fine sand recovery through the dewatering screen. This helps achieve an appropriate particle size distribution while reducing the mud content to below 0.7%.

3. High-Frequency Dewatering Screen

The high-frequency dewatering screen is designed to facilitate the environmentally responsible recovery and utilization of waste materials. It features high processing capacity and excellent dewatering performance and is suitable for material dewatering and screening under high-frequency, high-intensity vibration conditions.

4. Tailings Dewatering Screen

The tailings dewatering screen is widely used for dry tailings discharge, tailings dewatering, and related applications. It is particularly suitable for processing fine mineral particles and can be used for automatic solid-liquid separation and dry tailings discharge. It can also be combined with a hydrocyclone to form an integrated tailings dewatering and recovery system, providing high dewatering efficiency.

Selection Guidelines

1. Dewatering vibrating screens are available in single-deck and double-deck configurations, with either left-hand or right-hand installation.

2. Available screen media include slotted screens, perforated screen plates, woven wire mesh, polyurethane screen panels, and other options. Custom designs are also available to meet specific operating requirements.

3. 3.To meet screening efficiency requirements, the screen deck may be installed at an inclination angle of 2°–10° to the horizontal when necessary. When placing an order, please specify the screen media type (woven, perforated, slotted, polyurethane, etc.), aperture size, processing capacity, and feed particle size.
