Description

The RC jaw crusher is used in the first process of crushing various minerals and rocks. It can process various ores with a compressive strength not higher than 320MPa to a medium particle size at one time. It is often used with cone crushers, impact crushers, and sand making machines. Together, it forms a complete set of sand and gravel production lines, which are widely used in mining, metallurgy, chemical, building materials, electric power, water conservancy, transportation and other fields.

Features

1. High-quality material finishing. The jaw plate and side guard plate are made of high manganese steel, the bracket plate is made of gray cast iron, and the eccentric shaft is made of high-strength forged steel. They are made through multiple precision machining, heat treatment and flaw detection, and have sufficient rigidity and strength.

2. The discharge port adopts double-jack hydraulic adjustment method, which makes the adjustment faster and more labor-saving.

3. Can withstand strong impact. Split welded cast steel frame, simple structure, strong impact resistance; heavy-duty eccentric shaft and bearing ensure the impact resistance of the movable jaw assembly; a heavy-duty guard plate is installed above the movable jaw to withstand the strong impact of materials.

4. Using finite element analysis technology, the movable jaw assembly is composed of high-quality cast steel parts, the heavy-duty eccentric shaft is processed from forging blanks, and the bearing seat is made of integral cast steel structure, which improves the equipment strength and operation stability while reducing the quality. .

Advantages

1. Overload protection mechanism. When the equipment is working, materials exceeding its crushing capacity may enter. These materials will adversely affect the operation of the equipment, or even damage the equipment. At this time, the bracket will break by itself to protect the equipment from damage.

2. Large size bearing with larger bearing capacity,which can be longer service life.

3. When the non-crushed material enters the crushing chamber, the bracket breaks to protect the valuable parts of the equipment from being damaged; the hydraulic cylinder has an overload protection function. When overloaded, the reverse flow valve discharges the hydraulic oil in the hydraulic cylinder, and the wedge moves outwards, and the discharge port Get bigger.

4. Easy to operate and maintain. Gasket-type discharge adjustment device, centralized lubrication system, easy to operate and easy to maintain; the jaw plate has a symmetrical structure, which can be used up and down after being worn, which increases the life cycle and saves replacement costs.

Working Principle

RC Jaw crusher is mainly composed of frame, eccentric shaft, large pulley, flywheel, side guard, toggle, toggle back seat, clearance screw, return spring, fixed jaw and movable jaw.

The crushing method of the jaw crusher is a curved extrusion type. When working, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate closer to the fixed jaw plate, and the material passes through the two jaws. The squeezing, rubbing, and grinding between the plates realize multiple crushing; when the movable jaw moves down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the pull rod and spring, and the material has been crushed Under the action of gravity, it can be discharged freely through the discharge port at the lower part of the jaw cavity. With the continuous rotation of the motor, the movable jaw is periodically crushed and discharged to realize mass production.
