SQUARE TUMBLER VIBRATING SCREEN FOR QUARTZ SAND

The working principle of the square tumbler screen is: after the tumbler 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 tumbler screen can also be called a gyratory 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 tumbler 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.
