Industrial screening machine 

Product description
The straight-row sieve is a compact and easy-to-move screening equipment. It is mainly composed of a sieve box, sieve screen, vibration motor, vibration damping device and frame. Through the excitation effect of the vibration motor, the materials move on the sieve surface to achieve screening. It has the characteristics of large processing capacity, high efficiency, low energy consumption, high screening accuracy, easy cleaning and maintenance, good sealing performance, and quiet operation. It is widely used in the screening and impurity removal of powder particles in industries such as food, chemical, pharmaceutical, and metal powder.
 
Working principle
The straight-through vibrating screen uses one or two horizontal vibrating motors as the excitation source, with the vibrating motors placed on both sides of the machine body. The vibrating motor converts the rotational motion into a multi-force superposition of horizontal, vertical, inclined and centrifugal forces through two sets of unbalanced eccentric blocks at the upper and lower ends of the shaft, and then transmits it to the screen surface. By changing the phase angle and weight of the upper and lower eccentric blocks, the magnitude of the excitation force and the movement trajectory of the material can be altered, enabling the material to perform an elliptical movement trajectory on the screen surface, quickly and reciprocally completing the over-net action. At the same time, the vibration force can continuously exert the effects of stripping, breaking up and reorganizing on the material, thus allowing the material to quickly pass through the screen. Materials that cannot pass through the screen are discharged from the upper discharge port of the screen according to the movement trajectory of the equipment, completing the screening process.
 
Product Features

1. Large processing capacity: The large flow outlet at the bottom enables rapid discharge, with a high output. It is 2-5 times that of a regular round screen. The material stays on the screen for a short time, allowing for quick screening and discharging processes.
2. High efficiency and low energy consumption: Utilizing the efficient vibration excitation of the vibration motor, the material moves and passes through the mesh quickly on the screen. It has low energy consumption and can be continuously produced 24 hours a day. It has a high degree of automation and saves labor costs.
3. High screening accuracy: It can be used in single or multiple layers. By setting different-sized holes or openings on the screen to control the particle size classification during screening, it enables multiple-level screening in one process, suitable for rough screening and precise screening of granular and powder materials.
4. Compact structure: Small in size, it does not occupy space, is easy to move, and is convenient for installation and layout. It can be flexibly adjusted in position according to on-site needs.
5. Easy cleaning and maintenance: Easy to disassemble and assemble, easy to clean both inside and outside, without any hygiene dead corners, in line with food-grade GMP standards, and the external structure of the vibration motor is easy to maintain.
6. Good sealing performance: Adopting a fully enclosed structure, it is rigorous in sealing, with no leakage of liquids and no dust flying. It ensures a clean working environment and prevents material leakage and pollution.
7. Silent design: Ultra-low noise design, with low noise during operation, reducing noise pollution to the working environment.
