Product Introduction
The jaw crusher is one of the earliest types of crushing equipment. Due to its simple structure, robustness, reliable operation, ease of maintenance and repair, and relatively low production and construction costs, it remains widely used today in various industrial sectors such as metallurgy, chemical engineering, building materials, power generation, and transportation. Jaw crushers are primarily used for medium-sized crushing of diverse ores and large-sized materials, and are extensively employed in industries including mining, smelting, building materials, highways, railways, water conservancy, and chemical engineering.

The crusher employs a toggle-jaw crushing mechanism. When the electric motor drives the belt and pulley, the eccentric shaft causes the moving jaw to oscillate up and down. As the moving jaw rises, the angle between the toggle plate and the moving jaw increases, thereby pushing the moving jaw plate closer to the fixed jaw plate. At the same time, the material is crushed, rolled, and rubbed, achieving the desired crushing effect. When the moving jaw descends, the angle between the toggle plate and the moving jaw decreases, and under the action of the tie rod and spring, the moving jaw plate moves away from the fixed jaw plate. The crushed material then falls out through the discharge opening at the bottom of the crushing chamber, driven by its own weight. As the electric motor continues to rotate, the moving jaw of the crusher performs periodic crushing and discharging cycles, enabling continuous batch production.
Product Features
1. Overall riveted assembly: Overcomes the drawback of welded frames being prone to stress concentration, making it more robust and reliable.
2. Heavy-duty eccentric shaft forging and machining: Ensures exceptional reliability for jaw crushers.
3. Hydraulic Control: The jaw crusher, equipped with a hydraulic oil station, facilitates easy cavity cleaning and ensures that the machine’s lubrication system supplies oil to all components requiring lubrication, thereby guaranteeing safe operation of the machine. Moreover, when the crusher stops under load, the hydraulic cavity-cleaning system can quickly clear the crushing chamber, significantly reducing downtime.
4. V-Shaped Structure: The “V”-shaped crushing chamber and toothed guard plate design of the jaw crusher are more rational, ensuring consistency between the actual feed size and the theoretical feed size. This effectively increases the crushing area, prevents material blockage within the crushing chamber, maximizes the crushing efficiency and output, and enhances the utilization rate of the jaw plates.
5. Wedge Device: The quick-adjusting crusher employs a wedge-type discharge opening adjustment system, enabling the machine to set the discharge opening to the predetermined value within just a few minutes—even when running at no load.

The maximum feed particle size is 0.8 times the dimension of the feed inlet. The output outside the machine also depends on factors such as the mud content, moisture content, bulk density, and crushability of the material.
