Difference of Rotary and Linear Vibrating Screen

May 13, 2022 Vibro Screen Separator

Rotary vibrating screen is also called three-dimensional vibrating screen. Through the operation of the driving equipment of the vibrating motor, the material forms a three-dimensional movement on the screen surface to achieve the purpose of screening.

The linear vibrating screen is also called a rectangular vibrating screen. The motion trajectory of the screen box is a straight line or close to a straight line. It has two axes, so it is also called a dual-axis vibrating screen.

Features Difference

Rotary vibrating screen
①High efficiency, exquisite design, easy to change the screen, simple operation, easy to clean.
②The new screen structure with long service life, and it only takes 3-5 minutes to change the screen.
③It takes up small space and is easy to move, and the discharge port can be rotated 360 degrees at will.
④Fully enclosed structure, no dust flying, no clogging of mesh, and screening can reach 500 mesh.

Linear vibrating screen
①Simple structure, convenient installation and easy maintenance.
②Low energy consumption, high output, single-layer and multi-layer screens can be used, and the service life is long.

Working Principle Difference

Rotary vibrating screen

Through the eccentric hammer installed up and down the vertical vibration motor, the rotary motion of the motor is transformed into horizontal, vertical and inclined three-dimensional motion, and then this motion is transmitted to the mesh surface, changing the phase angle of the upper and lower weights of the motor can change the material movement direction.

Linear vibrating screen

Driven by dual vibration motors, the two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the self-gravity of the material, the material moves forward in a straight line on the screen surface in a jumping style.

Application Difference

Rotary vibrating screen

Mainly used in chemical industry, food, metal metallurgy mining, pollution treatment, etc.
Chemical industry: resins, coatings, industrial medicines, etc.
Food industry: powdered sugar, starch, salt, rice flour, etc.
Metal metallurgy and mining: aluminum powder, lead powder, copper powder, manganese dioxide, etc.

Linear vibrating screen

Mainly used in plastics, abrasives, medicine, building materials, food, fertilizer and other industries.
Such as: powder, granules, etc.
