Product Profile of Heavy Duty Jaw Crushers
Supertech manufactures Heavy Duty Jaw Crushers. Supertech supplies variety of Cement Machines, Phosphate Fertilizer Plants, etc. The Jaw Crushers are heavy duty double toggle machines designed for long life service and minimum of maintenance for hard tough and/or abrasive materials. In the Heavy Duty Jaw Crushers, the pitman shaft/eccentric shaft mounted in pitman imparts motion to moveable jay plate mounted on hinged swing lever/ swing jaw by means of toggle plates. The location of swing lever hinge point is correctly located to do crushing without rubbing.
Key Features of Heavy Duty Jaw Crushers
- Frame [Body]: The frame is made of heavy steel plates with reinforcing members welded in place. It is fabricated as a unit with all bearing seats in place and stress relieved.
- Swing Jaw [Swing Lever]: The swing jaw is either M.S. Fabricated or C.I. and machined to accommodate swing jaw bearings and front toggle seat.
- Swing Jaw Pin & Suspension: The swing jaw pin is made of medium carbon steel. It is seated and clamped to the main frame. The swing jaw is freely pivoted on the shaft.
- Pitman: Pitman is fabricated from M.S. Plates alternatively in one piece casting duly normalized. The pitman is machined to receive large size antifriction bearing and provision is made for grease lubrication. Sealing covers are provided to retain grease and exclude dirt. Recesses are provided in the bottom for centre toggle seats.
- Pitman shaft: The pitman shaft or eccentric shaft is special steel [Railway Axle] and machined all over to suit the bearings. The ends are key seated for fly wheel and fly wheel sheave.
- Pitmen shaft bearings and block: Pitman shaft bearings are double row spherical roller bearings. These blocks are clamped to the frame and provision is made for grease lubrication. Covers are provided to retain lubricant and exclude dirt.
- Jaw Plates: Jaw plates are of non-choking design reversible and of Manganese steel containing 12 to 14% manganese conforming to IS 276. They are clamped in position.
- Side Plates: M.S. side plates are machined and are provided to act as protection for main frame against any wear due to material being crushed in crusher mouth
- Toggle system: The toggle system is of four bearing type. Front and rear toggle plates are of steel and ride in machined M.S. bearings seated in the swing jaw, pitman and toggle block.
- Tension system: A system of rod/rods and spring is attached to the bottom of the swing jaw and crusher body/frame to keep the swing jaw and toggle system tight.
- Product size setting: By advancing rear toggle plate by lowering wedge bloc the setting can be reduced.
- Fly wheel and fly wheel sheave: The components are made of C.I. and keyed to the pitman shaft. The wheels are statically balanced.
- Lubrication: Crusher is arranged for grease lubrication. Provision for lubricating bearings is provided.
- Drive: The drive to crusher is by means of one set of `V` belts, prime mover can be electric motor/diesel engine
