What is Jaw Crusher?

Designed to crush a wide range of materials, the jaw rock crusher in crushing applications such as medium rock, hard rock, reinforced concrete and asphalt. Jaw crushers are ideal for contractors and quarry operators.

Stone jaw crusher machine is the earliest crushing equipment that appeared. Because of its simple structure, solidity, reliable operation, easy maintenance and overhaul, and relatively low production and construction costs, it is still widely used in metallurgy, chemical industry, building materials, electric power, In industrial sectors such as transportation, it is used for coarse, medium and fine crushing of various ores and rocks with a compressive strength of 147-245MPa. In recent years, our factory has specially developed a jaw crusher machine to meet the needs of industrial sectors such as metallurgy, mining, and construction for crushing high-strength, high-hardness microcarbon ferrochrome.

Jaw crusher working principle and structure

Working Principle

The working mode of this series of crushers is drive extrusion type. Its working principle is: the motor drives the belt and pulley, and the movable jaw moves 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 The movable jaw plate approaches the fixed jaw plate, and at the same time, the material is crushed or chopped to achieve the purpose of crushing; when the movable jaw moves downward, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate moves under the action of the pull rod and the spring. down, leaving the fixed jaw plate, and the crushed material will be discharged from the lower opening of the crushing chamber. As the motor continuously rotates, the movable jaw of the crusher makes periodic movements to crush and discharge materials, thus realizing mass production.

Structure Composition:
Jaw crusher machine mainly consists of frame, eccentric shaft, large pulley, flywheel, movable jaw, side guard plate, elbow plate, elbow plate back seat, clearance screw, reset spring, fixed jaw plate and movable jaw plate, etc., of which the elbow plate also plays the role of insurance. The whole equipment has a compact structure and works stably and reliably.

Application of Jaw Crusher

Jaw rock crushers is widely used in the crushing operation of various ores and rocks, such as limestone, river pebbles, basalt, iron ore and so on. At the same time, it is also suitable for crushing and recycling of construction waste, as well as aggregate production in the construction of highways, railroads, water conservancy and other infrastructures. Whether for large-scale mining or small-scale gravel quarry production, the jaw crusher can provide stable and reliable crushing solutions.

The following is the analysis and suggestion of the combination of jaw crusher and different production lines:
·Sand and gravel production line:
·Combination: Jaw crusher + cone crusher/impact crusher + sand making machine + sand washing machine + screening equipment
·Suggestion: Firstly, use jaw crusher for coarse crushing of large stone, then use cone crusher or impact crusher for medium crushing, then use sand making machine for fine crushing and shaping, and finally get sand and gravel products with different granularity through sand washing machine and screening equipment.
·Ore crushing production line:
·Combination: Jaw crusher + Cone crusher/impact crusher + Vibrating screen + Belt conveyor
·Recommendation: Jaw crusher is responsible for the initial crushing of the ore, followed by cone crusher or impact crusher for medium and fine crushing according to the hardness and size requirements of the ore. Vibrating screen is used to screen different size of ore, and belt conveyor is responsible for material transfer.
·Construction waste treatment production line:
·Combination: Jaw Crusher + Impact Crusher/Hammer Crusher + Magnetic Separator + Vibrating Screen + Belt Conveyor
·Suggestion: The construction waste is first roughly crushed by a jaw crusher and then further crushed using an impact crusher or hammer crusher. Magnetic separator is used to separate the metallic materials and vibrating screen is used to screen the aggregates with different particle size. Belt conveyor plays the role of material transfer in the whole production line.
·Mobile crushing line:
·Combination: Mobile Jaw Crushing Plant + Mobile Cone Crushing Plant/Mobile Impact Crushing Plant + Mobile Screening Plant
·Suggestion: For crushing tasks that require frequent transfer or complex site environment, mobile crushing plant can be chosen. The mobile jaw crushing plant is responsible for coarse crushing, the mobile cone crushing plant or mobile impact crushing plant for medium and fine crushing, and the mobile screening plant for screening and classification.

Product Advantage

The jaw crusher machine is designed with careful details and the improved structure ensures good operating results. It gives the equipment the following advantages and brings greater value to users.
1. Strong feeding capacity
The deep crushing cavity meets larger feeding needs and improves crushing efficiency.

2. High-strength steel plate toggle plate
It is light in weight, easy to replace, and bends when overloaded, which avoids damage to the conveyor belt when the traditional cast iron toggle plate breaks and falls.

3. Hook wedge key
It is used to connect the flywheel and the spindle to facilitate disassembly and assembly.

4. Flywheel counterweight system
The careful design of the position of the flywheel counterweight improves the performance of the entire motor balance system.

5. Reserved structure
The design is lightweight and small in size, saving space and making installation and transportation more convenient.
