Product Overview

Excessive focus on screening accuracy often comes at the cost of output, while pursuing high output tends to reduce accuracy. The rectangular gyratory sifter is a high-efficiency screening equipment specially designed to solve the above problems, featuring both high precision and large capacity. It is widely used in chemical, metallurgical, non-ferrous metal, non-metallic mineral, food, abrasive and other industries.

Features & Applicable Industries

Excellent self-cleaning screen effect

Chemical industry (fertilizer, resin, melamine, soda ash, etc.)

High screen utilization rate and long service life

Food industry (starch, salt, granulated sugar, milk powder, etc.)

Good sealing performance

Metallurgy, non-ferrous metals, non-metallic minerals, magnetic materials, etc.

Working Principle  Technical Parameter

Judging from the motion trajectory of the vibrating body (screen box), the rectangular gyratory sifter is also known as a reciprocating sifter. The vibration force generated by its drive unit is an inertial force that changes regularly around a fixed axis, essentially a reciprocating inertial force formed by the rotation of an eccentric wheel around the fixed axis.

Based on its structural characteristics and working principle, the screen surface is generally arranged horizontally or slightly inclined (with an inclination angle of 0–5 degrees). When the sifter starts up, the screen box performs reciprocating back-and-forth motion under the action of inertial force, driving the screen surface to shake periodically. As a result, materials on the screen surface move directionally and jump along with the screen box.

During this process, particles smaller than the screen openings pass through to form the undersize product, while particles larger than the screen openings are discharged from the outlet after continuous rolling and jumping, thus completing the screening operation.
