Material Testing Equipment

We are engaged into providing Material Testing Equipment which are made out of the materials steels that delivers the best quality. These Material Testing Equipment are very helpful in grinding and crushing. The variety of Material Testing Equipments which can be found under this category are Lab Pulverizer, Lab-Jaw Crusher, Roll Crusher and Coal Jaw Crusher.

Laboratory Pulveriser

Rajco Laboratory Pulverizer is a disc type grinder, designed for grinding material to produce a fine mesh sample in one operation. It is a self contained grinder furnished with a rotating disc having a planetary movement in a vertical plane. This feature gives added life to the wearing parts and delivers a product to uniform fineness. The pulverizer will reduce 1 pounds sample of quartz type material to 100 mesh in 1 minute. Maximum feed size is ΒΌ inch Grinding is done between two discs one of which is stationary and the other revolving eccentrically at high speed. The apparatus is supplied with heat treated disc of 7 inches in diameter Adjustment of size of product may be made by use of a convenient hand wheel while the machine is in operation or at rest. A self locking device holds the hinged grinding chamber in place and affords easy and quick access to the grinding chamber for removal of ground samples and for cleaning.The pulverizer is supplied complete with a 3 H.P. motor, starting switch, V-belt pulley drive and mounting Electrical requirements are 440 volts, 3 phase A.C.

Laboratory Jaw Crusher

The RSEP Laboratory Jaw Crusher is designed to speed up the crushing of aggregate, ores, minerals, Coal, Coke, Chemicals and other similar materials. It is compact and of rugged construction for general laboratory or small pilot plant operations.Two jaws of manganese steel are provided in the jaw crusher. The movable jaw produces two blows for every revolution thus reducing over sizing to a minimum. A combination of forward and downward and strokes with a rocking action exerts pressure on the coarse material, yet permits the finished material to pass through the jaws. A hopper is provided at the top for feeding materials. The smooth jaws ensure a uniform product and easy cleaning is possible.

Technical Specification

Jaw Size : 100 x 150 mm
Max. Size of feed : 30 mm (approx)
Product discharge size : 6mm to 18mm (adjustable)
Capacity : 250 kg/hr (approx) (based on material)
Operation on : 440V, 3 Ph, 50Hz, A.C. complete with a 3 H.P. Motor, a starter V belt Pulley drive and mounting.

Roll Crusher

Roll Crusher comprise of two hardened alloy steel rollers with 100 mm. faces and 250 mm diameters. The rollers are fitted to a steel shaft and are mounted on heavy duty gunmetal bearings. The outside bearings are provided with heavy duty compression springs, which help in increasing the space between the rolls, when a piece of material cannot be crushed. Square threaded holts are provided to adjust the gap between the rolls. The drive is by a heavy duty motor, through V belts to a set of gears and further to the rollers. A hopper is provided for feeding the material. The whole arrangement is mounted on a fabricated steel frame. Supplied complete with a 3.0 H.P. motor, and strarter following sizes available.

(a) Size : 4 x 10 with motor 3 HP, 3PH
(b) Size : 6 x 10 with motor 3 HP, 3PH
(c) Size : 6 x 12 with motor 5 HP 3PH
(d) Size : 10 x 12 with motor 5 HP 3PH

Technical Specification

Size : 4
Motor : 3 HP
Diameter : 250 mm
Material : Alloy steel
