Industrial screening machine 

Product description
The direct discharge screen is a commonly used screening equipment. Its overall structure mainly consists of a screen box, a screen mesh, a vibrating motor, a base, etc. The vibrating motor generates an excitation force, causing the materials to move in a straight line on the inclined screen surface. During the movement, materials smaller than the screen mesh aperture pass through the screen mesh to become under-screen materials, while materials larger than the screen mesh aperture are discharged along the screen surface in a straight line. It can achieve the classification and screening of materials of different particle sizes, featuring high screening efficiency, large processing capacity, compact structure, and simple operation and maintenance. It is widely used in the material screening operations of the chemical, food, building materials and other industries.
 
Working principle
The direct discharge screen is a common screening equipment. Its working principle is as follows: The direct discharge screen is mainly composed of a vibrating motor, a screen box, a screen mesh and other components. The vibration motor serves as the power source. Through the high-speed rotation of the eccentric block, it generates excitation force, causing the screen box to vibrate at a high frequency. After the materials enter the screen box from the feeding port, they are rapidly dispersed under the action of vibration and move in a straight line on the screen. Material particles smaller than the size of the screen holes pass through the screen mesh and are discharged as under-screen materials. While the material particles larger than the sieve hole size continue to move forward on the screen and are eventually discharged from the discharge port, thus achieving the screening and classification of materials of different particle sizes. This linear motion screening method enables the material to stay on the screen surface for a relatively short time, has a large processing capacity, and is less likely to clog the screen holes, effectively improving the screening efficiency and quality.
 
Product Features

High-efficiency screening: By using the high-frequency vibration generated by the vibrating motor, the material moves rapidly in a straight line on the screen surface, which can quickly separate materials of different particle sizes, has a large processing capacity and high screening efficiency.

Not prone to clogging: The linear motion mode shortens the residence time of materials on the screen and increases the vibration intensity, making it less likely for materials to clog the screen holes and ensuring the smooth progress of the screening process.

Simple structure: It is mainly composed of basic components such as a vibrating motor, a screen box, and a screen mesh. The overall structure is simple, making it easy to install, maintain, and operate. The equipment has high reliability, a low probability of failure, and relatively low maintenance costs.

Strong applicability: According to different screening requirements, screens of different pore sizes can be replaced. It is suitable for screening various industries and types of materials, such as granular and powdered materials in the chemical, food, pharmaceutical, building materials and other industries.

Good sealing performance: The screen box is usually designed with a good sealing structure, which can effectively prevent the leakage of materials during the screening process, avoid material waste and environmental pollution, and is especially suitable for handling toxic, harmful or dust-prone materials.
