Circular Motion Screen

Circular Motion Screen is known for low profile, efficient protection of support structure from vibrating masses and virtually noiseless operation. The various versions of Circular Motion Screen allow wet and dry screening, coarse and fine separations. Circular Motion Screen is widely used in steel mills, mineral Beneficiation plants, chemical, mining, food and Fertilizer industries, coal preparation plants, and many others.
Product Structure
The vibrating screen consists of screen box, supporting device, vibration exciter, transmission part. The barrel-type vibration exciter is installed in the middle part of the machine. During normal operation, the vibration of exciter will drive the screen mesh fixed on the screen box vibrate, and then materials will be screened.
Applications
This machine are mainly used in chemical industry, power station, steel works, coal plant, mine, building sites, etc,. Our scalping screen can be customized to meet various requirements. High-quality and safe operations. With single or multiple screen decks. Sand and gravel, building materials minerals, ores, pellets, sinter coal, coke, lignite, limestone, dolomite, chemical products, fertilizers.
Vibrator Unit
The vibrator Unit is a steel shaft, completely housed in a protective steel tubular casing which in turn is provided with an easily replaceable rubber cover to resist damage and abrasion. Balance Weights are keyed to shaft. The bearings are specially designed for the use on screens and are a high capacity self aligning double roller type.
These bearings have special tolerances and improved lubrication facilities to give extended bearing life under their ardous working conditions. Labyrinth type grease sealings are provided to prever dust getting into bearings. A deep groove V-belt Pully is bored eccentrically to ensure true running arn to obviate the belt whip.
Technical Data
The Circular Motion Screens are bolted single or multi deck structure with a substantial and rigid design. The screen body consists of the two side plates with bolted transverse supports and screen mounts. The screen box is based on an open design. Drive shaft with its eccentric weights runs in heavy duty self-aligning roller bearings. The throw of the vibrating screen is varied by adjusting the eccentric weights.
The drive is either direct or through cordon shaft and v- belts. The vibrating screen is supported above the substructure by means of helical coil compression springs. The screen installation angle can be varied to suit the application. There are several options for lubrication, oil or grease, which can be used without modification. Selected bearing seals ensure a long service life.
Structures
A Type Circular Motion Vibrating Screen is consisted of Screen box, Screen, Vibrating motor, Reducing setting and Base plate. The angle of the screen could be changed by the adjustment of the height of the base plate. Usually the vibrating motor is fixed on the right side of the screen frame. We have all sorts of screens for our users to choose.
Working Principle

• The two same vibrating motors which rotate synchronously in different directions, making the screen body do periodical to-and-fro linear moving to achieve screen classification purpose.
  
• The crossbeam and side boards of screen are made of stainless steel plate or heat-resisting plate and connected by the rivets to decrease internal stress and make good fastness.

• Quick changing of screen mats and of the specially developed removable names, to allow lengthwise tensioning using simple screw connections.
  
• The machine is economically Equipped to customer's requirements with screen decks made of spring steel wire perforated sheet wire Perforated sheet metal, rubber or polyurethane optimum untilization of the screening area by a deck arrangement which is adapted to suit the grain size concerned, namely longitudinal, transverse, inserted and laid linings.
  
• Low noise level with grease lubricated circular drive units which run extremely quiet and are of a stable design with low harmonic oscillation.
  
• High availability and operational reliability is the result of a highly Developed design and quality Standard.
  
• Low maintenance costs resulting from a direct drive using a normal commercial motor and maintenance free card an shaft.
  
• Easy, quick installation and removable of worn and replacement parts by the use of screw connections.
