SIEVING EQUIPMENT SIEVE SHAKERS The Sieve Shakers are designed for intermittent dry sieving of bulk materials according to particle size. The Sieve Shaker consists of a vibration drive with a set of sieves installed, a tray, a cover and a device for fastening the sieves. The type of vibration drive, the number of sieves, and the intermediate rings and trays are selected depending on the order and according to the size of the mesh or the apertures in the perforated plate. Sieve Shaker А 12 on base VPS Sieve Shaker А 20 on base VP 30T

SIEVING EQUIPMENT CIRCULAR VIBRATORY SCREENERS AND CIRCULAR VIBRATORY SCREENER UNITS ON BASE PG The Circular Vibratory Screeners are designed for sieving bulk materials according to particle size classes. The operating principle of the Circular Vibratory Screeners is similar to the operating principle of the analyzer, except that supply of the material to be sieved and discharge of the separate classes from the surface of the sieve and tray are continuous. Circular Vibratory Screener GR 30 Circular Vibratory Screener GR 40

SIEVING EQUIPMENT ADVANTAGES OF CIRCULAR VIBRATORY SCREENERS UNITS: The distance traveled by the material particles during screening exceeds the diameter of the sieves installed, which improves sieving efficiency; Dust discharge is eliminated; The Circular Vibratory Screeners is equipped with corrugated discharge hoses and plastic receiving containers; Efficient screening using reciprocating helical vibrations of platform; Supply of elastic discharge hoses that do not distort the vibrations, for connecting pipes to receiving containers Pipe and skirt of sieve GR 50

SIEVING EQUIPMENT ADVANTAGES OF GR UNITS WITH PG: Uniform feed of material to upper sieve of Screener; The material feed rate is adjusted by: o moving the slide gate in the feed hopper; o changing the amplitude of the feed tray vibrations making it possible to change the thickness of the material layer in the tray. Sealed connection of feeder, sieving elements and receiving containers; Increased output of Circular Vibratory Screeners GR 40 and GR 50 through simultaneous loading of material into several identical sieves on one sieving column.

SIEVING EQUIPMENT TRAYS Material particles that have passed through all sieves of the sieving column are discharged to the analyzer trays. Intermediate trays are designed for the installation of several identical sets of sieves in one sieving column. The sieve shaker trays are designed for continuous discharge into the receiving container of the material that has passed through the lower sieve. Trays for sieve shakers GR 30 and GR 50 Trays with diameter of 120, 200, 300 and 500 mm

SIEVING EQUIPMENT COVERS The Sieve shaker and Circular Vibratory Screeners covers are designed to reduce the dust level; in addition, the Circular Vibratory Screeners covers are designed for loading material into the top sieve. There are four designs for the GR 30, GR 40 and GR 50 covers: with a funnel for portioned loading of material; with a pipe for sealed connection of an elastic hose; with a membrane for loading material through a rigid hose; with a water supply for wet sieving. Covers with diameter of 120, 200, 300 and 500 mm GR 30 cover with pipe and membrane, GR 50 cover with funnel

SIEVING EQUIPMENT SIEVE FASTENERS The sieve fastener UKS is designed to secure a sieve column of arbitrary height on a vibration drive platform. In addition to the sieve fastener UKS. UKS knob Sieve fastener UKS ADVANTAGES OF UKS: Use of industrial fittings that ensure convenient use and durability of the sieve fasteners; The main element of the sieve fastener, the cross piece, has two guide bushes that reduce the likelihood of it skewing; The cross piece has a square cross section to prevent deformation; The UKS knobs do not have continuous threads, but rather beveled threads, which eliminate the need to twist the knobs on the threaded pegs and reduce the time required to secure the sieve column when its height is changed.

SIEVING EQUIPMENT SIEVE HOLDERS The S 50 cassette is designed to store five А 50 or GR 50 sieves. ADVANTAGES: Compact storage of А 50 and GR 50 sieves, trays, covers and intermediate rings; Wooden inserts prevent the sieves from coming into contact with metal parts of the cassette; A handle and rollers are provided to move the cassette Cassette S 50
