What is the difference between tumbler screen and rectangular gyratory sifter ?
The swing screen is a device for manual screening action, and this series of equipment can be divided into tumbler screen and rectangular gyratory sifter according to the shape. What is the difference between these two devices?
Different Operating Modes
The tumbler screen is a low-frequency vibro sifter that imitates artificial shaking. It combines planar circular motion ─ sieve and upward parabolic motion ─ bumps to form a non-linear three-dimensional tumbling motion, the materials are evenly dispersed from the center to the outer edge on the screen surface, that is, the materials are dispersed from the center with an involute spiral motion to complete the screening operation.
The shaking body of rectangular gyratory sifter means that the sieve box reciprocates back and forth under the action of inertial force,the sieve box and the sieve surface are periodically shaken, so that the materials on the sieve surface make a directional jump movement along with the sieve box.During the period,the material smaller than the screen hole falls to the lower layer through the screen hole and becomes the sieve. The material larger than the screen hole diameter is discharged from the discharge port after continuous tumbling and jumping movement to complete the screening work.
The tumbler screen can effectively screen the materials that are spherical, cylindrical, flake, and even irregular shapes that are easy to block the net and require precise screening.
The rectangular gyratory sifter can effectively screen powder materials such as fertilizer, starch, metallurgy, non-ferrous metals, non-ferrous metals, magnetic materials, etc.
Different Net Cleaning Devices
The net cleaning device of the tumbler screen can have three types of net cleaning devices: bouncing ball, rotating brush and ultrasonic wave, and the corresponding net cleaning device can be selected according to the characteristics of the material.
The rectangular gyratory sifter is designed with an inclination angle of 0°~5°, so it does not need an additional net cleaning device.
