Product details
Product Features
Deep cavity jaw crusher is an early type of crushing equipment, which is widely used in various industrial sectors such as metallurgy, chemical industry, building materials, power, transportation, etc. due to its simple and sturdy structure, reliable operation, easy maintenance and repair, and relatively low production and construction costs. It is used for crushing coarse, medium, and fine ores and rocks with compressive strength ranging from 147 to 245 MPa. In recent years, our factory has specially developed a powerful jaw crusher to meet the needs of crushing high-strength and high hardness micro carbon chromium iron in industrial sectors such as metallurgy, mining, and construction. The E-type crusher is mainly used for medium particle size crushing of various ores and bulk materials, and is widely used in industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical engineering. The high compressive strength of the crushed material is 320MPa.
Performance advantages
Performance characteristics of deep cavity jaw crusher:
1. The crushing chamber is deep and there is no dead zone, which improves the feeding capacity and production of Hubei.
2. Its crushing ratio is large, and the product particle size is uniform.
3. The gasket type discharge port adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment.
4. The lubrication system is safe and reliable, with easy component replacement and minimal maintenance workload.
5. Simple structure, reliable operation, and low operating costs.
6. Equipment energy saving: Single unit energy saving of 15% to 30%, system energy saving of more than twice.
7. The adjustment range of the discharge port is large, which can meet the requirements of different users.
8. Low noise and minimal dust.
Structural composition
Structure composition of deep cavity jaw crusher:
The deep cavity jaw crusher is mainly composed of a frame, eccentric shaft, large pulley, flywheel, side guard plate, elbow plate, elbow plate rear seat, gap adjusting screw, reset spring, fixed jaw plate and movable jaw plate, among which the elbow plate also plays a safety role.
Precautions for the operation of deep cavity jaw crusher
Before using the deep cavity jaw crusher, it is necessary to check whether there are any foreign objects in the crushing chamber. If there are some foreign objects present, they should be cleaned up in a timely manner before starting the machine. Otherwise, the motor will be damaged due to excessive load during startup.
The fear of deep cavity jaw crusher is that the feeding amount is uneven during the feeding process, especially when the feeding amount suddenly increases, it will burn out the motor due to excessive load.
When production needs to be stopped, the feeding should be stopped first, and then the operation of the jaw crusher should be stopped. Because if the operation is stopped first, there will be a large amount of unprocessed ore materials stored in the machine, which will cause damage to the machine parts, and at the same time, it will overload the machine when restarted.
When using a deep cavity jaw crusher for production, it is necessary to promptly detect any abnormal sounds or other abnormal situations in the machine. After discovery, the cause should be promptly identified and repaired, and the machine should not be allowed to work with defects.
Working principle
The crushing method of the deep cavity jaw crusher is a curved extrusion type, and the operating principle mainly simulates the movement of the two jaws of animals. When working, the motor drives the belt and pulley, and the movable jaw moves up and down through an eccentric shaft. When the movable jaw rises, the angle between the elbow plate and the movable jaw increases, thereby pushing the movable jaw plate closer to the fixed jaw plate. The material is crushed multiple times through squeezing, rubbing, and grinding between the two jaw plates; When the movable jaw descends, the angle between the elbow plate and the movable jaw decreases, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. The crushed material is freely discharged through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the electric motor, the moving jaw performs periodic crushing and discharging, achieving mass production.
