Pebble crusher

The pebble crusher is commonly used for primary or secondary crushing in mining material crushing. The pebble crusher adopts the most advanced international crushing technology and manufacturing level, and is the preferred high-efficiency product for crushing hard and highly abrasive materials.

summary:

Mainly used for crushing hard rocks such as pebbles, with a specification of about 3-7 centimeters, and the hardness of the crushed materials is relatively high. Compared with traditional crushers, the pebble crusher has unparalleled advantages in terms of service life, maintenance rate, and failure rate. Compared with the use of stone shaping machines, the cost is also relatively low. This series of pebble crushers is mainly used in industrial sectors such as metallurgy, mining, chemical industry, cement, construction, refractory materials, and ceramics to crush medium and fine pebbles or rocks of equivalent hardness. It is a high-quality crusher.

working principle:

The pebble crusher mainly includes a machine base, a fixed jaw, a moving jaw, and an eccentric shaft. The fixed jaw is fixed with a fixed jaw toothed plate, which is fixed to the moving jaw through a connecting rod. The two sides of the moving and fixed jaw toothed plates are equipped with side guard plates, and the upper end of the moving jaw is fitted on the eccentric shaft. There is a bearing chamber between the moving jaw and the eccentric shaft, and the top of the moving jaw toothed plate is about 80-250mm higher than the fixed jaw toothed plate. The structure is simple and reasonable, and the raised movable jaw teeth plate provides good protection for the movable jaw and bearing chamber, while ensuring smooth feeding and avoiding material blockage and machine jamming. It is safe and reliable. In addition, this utility model simplifies the production of the movable jaw, with good sealing and operating performance of the movable jaw bearing chamber, no oil leakage, and improves the overall use of the machine. It has low noise, smooth operation, and obvious energy-saving effects, which is conducive to promotion and application. It is widely used in mining, building materials, silicates, metallurgy, road construction, chemical industry raw materials and other fields, especially suitable for crushing medium hardness materials such as rock, ore, cement clinker, etc.

Structural composition:

The pebble crusher mainly consists of a frame, an eccentric shaft rotating part, a crushing chamber working part, a safety device, and a discharge port adjustment device.

1. Rack section: composed of side panels, front box components, rear box weldments, etc.

2. Eccentric shaft rotating part: mainly composed of rotor, eccentric shaft, bearing, bearing seat, pulley, etc. It is the main part of transmitting power.

3. The working part of the crushing chamber is mainly composed of fixed jaw plate, moving jaw plate, side lining plate, protective plate, etc., which are the working parts for crushing materials.

4. Safety device: composed of elbow plate, elbow plate seat, spring, spring pull rod, etc., it is a part of the crusher that plays a safety role under abnormal conditions.

5. Discharge port adjustment device: This device is used to adjust the size of the discharge port and control the particle size of the discharge. It mainly consists of adjusting the fixed inclined block, adjusting the sliding inclined block, top screw bolt, sliding block locking rod, etc.
