Roller Vibrating Screen: Versatile, Efficient Screening Solutions

Roller Vibrating Screen

A roller vibrating screen, also known as a roller sieve, is a type of vibrating screen that utilizes cylindrical rollers instead of traditional screen panels to separate and classify materials.
  • Description

A roller vibrating screens are versatile and efficient screening solutions used in a wide range of industrial applications. Their robust design, high screening capacity, and versatility make them suitable for processing various bulk materials with precision and reliability.

Roller Vibrating Screens Structure

It consists of a box, a lining plate, a wearing disc, a drive shaft, a speed-regulating motor, a motor pedestal, a reducer, and a bracket. The box body is welded by Q345 steel plate, and the strength and rigidity have been tested many times and meet the requirements. Liners and discs are made of wear-resistant materials, which are durable and have a long service life. Refer to the manual for the use of the motor. The motor pedestal must be fixed so that the equipment can work stably. The reducer drive the wearing discs to move.

Roller screen vibrating screens working principle

The whole equipment is composed of a box, the screen surface is composed of a plurality of rollers, and there are discs on the rollers. When the equipment is started, the mud-rock mixture is fed by the chain conveyor, the motor drives the roller to rotate, the roller drives the disc to rotate, so that the material on the screen surface moves forward, and the soil falls out by the belt conveyor. , the stone can go to the next process. Frequency conversion speed regulation, almost no blockage.

Roller Vibrating Screens Features

Cylindrical Rollers: The main components of a roller vibrating screen are cylindrical rollers arranged horizontally or inclined at a slight angle. These rollers are typically made of steel or other durable materials and are mounted on shafts or supports.

Vibration Mechanism: The roller vibrating screen is equipped with a vibration mechanism, usually consisting of eccentric weights or unbalanced flywheels attached to the shafts of the rollers. When the motor rotates, it generates vibrations in the rollers, causing them to move in a circular or elliptical motion.

Material Separation: As the material is fed onto the roller vibrating screen, the vibrations of the rollers cause the particles to move along the screen surface. Larger particles tend to roll over the rollers, while smaller particles fall through the gaps between the rollers. This process effectively separates the material into different size fractions.

Adjustability: Operators can adjust various parameters of the roller vibrating screen, such as the amplitude and frequency of vibration, to optimize the screening performance for different types of materials and particle sizes. They can also adjust the angle of inclination of the rollers to control the material flow and screening efficiency.

Screening Efficiency: Roller vibrating screens are known for their high screening efficiency due to the rolling motion of the rollers, which promotes effective material stratification and particle separation. This results in improved screening capacity and reduced blinding or clogging of the screen surface.

Versatility: Roller vibrating screens are versatile and can be used for a wide range of applications, including screening of dry or wet materials, scalping ahead of crushers or grinding mills, dewatering, and classification of various particle sizes.

Low Maintenance: Despite their complex design, roller vibrating screens require relatively low maintenance compared to other types of vibrating screens. They are equipped with durable components and are designed to withstand the rigors of continuous operation in industrial environments.
