Product Description

Roller Screen

Owing to our wide experience in this domain, our company is counted among the foremost manufacturers and exporters of Roller Screen. With the support of our well qualified team of professionals, we are competent in manufacturing wide assortment of screens for our diverse clients. Offered Roller Screen is widely demanded in various industries such as pit & quarry industry, cement, coal processing plants and various other industries. Our clients can avail this roller screen from us at very reasonable price.


Field of Application

Roller Screens are suitable for classifying coarse, moist or clayey raw materials. They are used for primary screening as well as for classifying (after crushing). Roller Screens are used in coal processing plants, in the cement, pit and quarry industries as well as around coal power stations.

Feed Materials
Hard coal and lignite, limestone, gypsum and similar materials.

Mode of Operation

  • Roller Screens sort feed materials with rotating rolls that are driven in parallel. The rolls are equipped with discs which may vary in shape. The size reduction of over-sized parts separated at the screen overflow is carried out by Double Roll Sizer or Hammer Mills.

  • For sorting into specific grain sizes the rolls are arrayed at a set distance. Thus, square or rectangular screen apertures are formed, allowing the passage of feed material with the desired dimension. Feed material that does not pass through the screening rolls is discharged and conveyed to the downstream crusher. Due to the even rotation of the Roller Screen rolls, the feed material is subject to a harmonic rolling motion and gently classified. In case of very moist, sticky or clayey raw materials the rolls are fitted with scrapers which clean the bottom of the roll to ensure efficient classification. The scrapers are individually adjustable and can be heated for extreme tasks.


Depending on the application, various machine designs and/or accessories can be used:

  • Roller Screen with horizontal arrangement

  • Roller Screens with inclined arrangement

  • Firmly installed adjustable scrapers

  • Heated Scrapers (steam-heated)

  • Surrounding scrapers being linked via band chain

The Swivel - Arm Crusher - Simultaneous Crushing And Classifying
Swivel-Arm Crushers combined with Roller Screens are mainly used for lignite processing in power plants. When compared to other crushing systems, the Swivel-Arm Crusher is not installed after the Roller Screen but integrated above the screening surface. This option offers the significant advantage of simultaneous crushing and classifying of feed materials. the swivel-arms are connected in parallel and fitted with driven crushing discs to reduce the crushable constituents contained in the feed material. In case of foreign particles the slewable arm is automatically raised to allow separate passing of the parts to the overflow.

Feed material specification and throughput capacity determine machine size, shape of the discs as well as distance and speed of the rolls. Rollers Screens are arranged either horizontally or inclined. In most cases, each shaft is individually driven.


  • High specific throughput capacity at low power requirements

  • Low spare parts requirement

  • Smooth and quiet run

  • Adequate primary screening machine for downstream crusher (i.e. Double Roll Sizer, Hammer Mills and similar)

Scope of Applications

  • Feed Size: Up to approx. 250mm

  • Product Size: Up to approx. <1mm depending on the feed material and its size

  • Capacity: Up to approx. 300 t/h

  • Max. required power: Approx. 200kW


  • Automatic gap adjusting device for the secondary crushing stage

  • Automatic grease lubrication system

  • Roll Turning lathe
