Square swing screen

Square Swing Screen

Product introduction

The fine shaker, also known as the square shaker, adopts a hanging structure and is a high-efficiency screening equipment with high precision and large output. During use, the user can meet the screening requirements of different materials by increasing or decreasing the spindle speed and the size of the exciting force within a certain range. The screen machine adopts a fully enclosed structure, and the screen mesh is usually fixed by tensioning on both sides, which is convenient for installation. It is usually 5-layer and 3-layer design, which can screen 6 or 4 kinds of materials at one time, or install a layer of screen for use.

Product application

Application areas: suitable for mining, casting, abrasives, building materials, cement, chemical industry, fertilizer, medicine, light industry, papermaking, food, sugar, salt, grain and other industries.

Equipment advantages: 1. Reasonable design, simple structure and stable operation;

2. Each layer of screen has a screen anti-blocking cleaning device. The screening machine continuously cleans the screen under working conditions to ensure that the screen does not block holes and prolong the operation period;

3. Good sealing effect, low noise, no dust, improve the working environment of the workshop;

4. The reciprocating and rotating movement method quickly disperses and sieves the materials;

5. There is no vertical vibration, the dynamic load to the foundation is small, and the screen mesh has a long service life.

Working principle: From the perspective of the movement trajectory of the screen box, that is, the screen box, the square rocking screen is also called a reciprocating screen. The vibration force generated by the driving device is an inertial force that changes around a fixed axis and in a certain direction. Its essence is The reciprocating inertial force formed by the rotation of the eccentric around the fixed axis. According to the structural characteristics and working principle of the swing screen, the screen surface is generally arranged horizontally or slightly inclined (the inclination angle is 0°~5°). The working principle of the gyratory screen is that after the screen machine is started, the shaker of the screen machine, that is, the screen box reciprocates back and forth under the action of inertial force, and the screen box drives the screen surface to periodically shake, so that the materials on the screen surface follow the screen box. It is a plane rotary motion together, during which, the material smaller than the sieve surface aperture falls to the lower layer through the sieve hole and becomes the under-sieve material, and the material larger than the sieve surface aperture is discharged from the discharge port after continuous tumbling and jumping motion to complete the screening work.
