It all comes down to delivering the most tons of material, the most cost effectively. Built to deliver a low cost per ton, the M. R. Engineers Single Toggle (MST Series) jaw crusher is designed for exceptionally heavy and continuous applications.

Utilizing the latest technology, this crusher delivers high production, infinite setting adjustment and large feed opening. This crusher is engineered to handle hard rock, ores and demolition concrete for the quarrying, mining and recycling industries

Jaw crusher benefits

Main Frame
Extra Heavy duty, welded by sophisticated welding techniques, thermally stress relieved, high strength steel frame withstands the constant pressures of crushing. Body is ribbed by thick plates to give adequate strength. Repairable crusher construction.

Eccentric Shaft
Massive, oversized, heat-treated shaft forged of special alloy to provide an exceptionally large eccentric throw and to handle overloads and hard materials. Jaw crusher eccentric shaft is also ultrasonically tested.

Our heavy duty, premium quality, grease lubricated self aligned spherical roller bearings offer substantially more bearing life and feature true rolling motion and ability to carry severe radial and thrust loads.

Toggle Plate
It is a safety System designed to shear protecting crusher components if non-crushable object is introduced to crusher.

Bearing Housings
Made of Graded Cast Steel IS:1030. Removable bearing housings make servicing easier and guard against contamination. Long life Bearing Housing and less maintenance.

Fly Wheel
Made of Solid Cast Iron Grade – 20 driven by V- Belt or Flat Belts. Extra large diameter, counter Weight to balance the eccentric load of the Machine and heavy split hub flywheels for smooth operation even in tough conditions which helps to reduce power consumption.

Jaw Stock
Jaw Stock (Pitman) designed to handle severe crushing conditions.It can be removed from the frame as an assembly. Mild steel fabrication and precision machined for greatest strength with minimum weight. It achieves its movement through the eccentric machining of the flywheel shaft.

Tension Rod
Without the tension rod & spring the bottom of the pitman would just flop around as its not connected to the toggle plate, rather just resting against it in the toggle Bearing. The tension rod system tensions the pitman to the toggle plate.

Side Plates
It helps to protect the Crusher Body made of high-strength manganese steel Grade – III.

Movable Jaw Plate and Fixed Jaw Plate
These jaw plates move regularly and crush the input materials to required fineness. Deep pitch gripped jaws for maximum reduction. The jaw-faces are fully reversible. All the Jaw Plates are cast with high strength manganese steel Grade- III enriched with Chromium.

Close running annular/labyrinth seals protect the bearings from dust and water.

Toggle Bearing
They protect the wearing of the toggle block and the lever Assembly. These Toggle Bearings are cast in special grade steel.

Toggle Block
It is supported by adjustable screws and allows horizontal setting of the toggle block. It is used for fine adjustment of the closed side settings.
