Manufactur standard Standard Sieve - square tumbler vibrating screen for Quartz sand – Trufiner

Working principle

The working principle of the square rocking screen is: after the rocking screen is started, the equipment rocking body, that is, the screen box, reciprocates back and forth under the action of inertial force, and the screen box and the screen surface are connected periodically to shake, so that the material on the screen surface will follow. The screen box makes a directional jumping motion together.

The square rocking screen can also be called a reciprocating vibrating screen. The vibration force generated by the motor drive device is an inertial force that changes in a certain direction around a fixed axis. The essence is the reciprocating inertia formed by the rotation of the eccentric wheel around the fixed axis. force. According to the structural characteristics and working principle of the R series square rocking screen, the screen surface is generally arranged horizontally or slightly inclined (the inclination angle is 0°~5°). The working principle of the R series square rocking screen is: after the rocking screen is started, the equipment rocking body, that is, the screen box, reciprocates back and forth under the action of inertial force, and the screen box and the screen surface are connected periodically to shake, so as to make the screen surface The material moves in a directional jumping motion with the screen box. During the period, the material smaller than the sieve hole falls to the lower layer through the sieve hole and becomes the under-sieve material, and the material larger than the sieve hole diameter is discharged from the discharge port after continuous tumbling and jumping motion, thus completing the screening work. It can be seen from the working principle of the R series square rocking screen that the eccentric wheel distance of the transmission mechanism has an important influence on the movement trajectory of the material and the residence time of the material on the screen surface, that is, it has an opposite effect on the processing capacity of the screen and the screening efficiency influence. In actual screening operations, we can make trade-offs in terms of production capacity and screening efficiency according to specific circumstances.

Product advantages 

● Using the principle of plane rotation to improve the distribution of materials on the screen and effectively improve the utilization rate of the screen Higher screening accuracy.

● Suitable for irregular materials such as cylindrical and flakes, the screening accuracy is as high as 98%, which is several times or higher than that of ordinary vibrating screens

● Keeping clean throughout the work process can reduce pollution to the environment

● It can be used in single layer or multi-layer, each layer of screen is equipped with a comb-type cleaning device, which has a large screening capacity and a unique multi-layer classification design. .

● Fully enclosed structure, no dust flying, small vibration and low noise of the screen machine, which meet the requirements of environmental protection.

● Flexible screening, the acceleration is 4-5 times lower than the ordinary vibrating screen, and the service life is increased, thereby reducing the maintenance cost.

● It is more convenient to change the net, the operation is simple, firm and reliable.

● Large-scale electrostatic spraying process, the equipment is more beautiful, wear-resistant and rust-proof.

● Rotary reverse screening: The material is screened by fine→medium-fine→medium→coarse, and the coarse material plays a certain role in cleaning the mesh.
