The process of jaw crusher crushing granite slab into gravel can be summarized in detail as follows:
The jaw crusher is mainly composed of a fixed jaw plate and movable jaw plate. The movable jaw plate is connected to the drive device through the eccentric shaft, which enables it to move up and down.
Movement principle:
When the movable jaw plate moves downward, the material (i.e., the granite slab) is placed in the crushing chamber and is subjected to the extrusion force between the fixed jaw plate and the movable jaw plate.
With the periodic movement of the movable jaw plate, the material is subjected to the combined effects of crushing, splitting and bending, thereby crushing into smaller particles.
Crushing process:
When the movable jaw plate moves downward, the material is subjected to the extrusion force and gradually crushed into smaller particles.
The slit between the jaw plates gradually narrows, causing the material to be subjected to increasing pressure, and the pressure is concentrated in a smaller area, thereby crushing the material.
Movement cycle:
After completing a downward movement, the movable jaw plate will move upward through the eccentric shaft to discharge the material from the crushing chamber.
Then, the movable jaw plate moves downward again to start the next crushing cycle.
2. Advantages of crushing granite slabs
Strong applicability: Jaw crusher is a well-known coarse crushing equipment in the sand and gravel industry, which can coarsely crush materials with hardness and particle size, such as granite slabs.
High efficiency and high yield: Its feed particle size can reach 1280mm, and the output range is 160-1510t/h, so it can efficiently crush granite slabs into the required gravel.
Simple structure: The structure of the jaw crusher is relatively simple, easy to maintain and operate.
3. Operation process
• Preparation: Check the appearance and working condition of the crusher, clean the residue and impurities inside the crushing chamber, and ensure that the lubrication system is sufficient.
• Start the crusher: Turn on the power switch, start the motor, and wait for the crusher to run normally and reach the set speed.
• Feeding: Open the feed port, evenly feed the granite slab into the feed port, and control the speed and uniformity of feeding.
• Adjust the discharge port: Adjust the size and position of the discharge port as needed to control the particle size of the crushed gravel.
• Monitor the operating status: Continuously observe the operating status of the crusher, pay attention to whether there is any abnormal sound or vibration, and check the current and voltage regularly.
• Shutdown: Stop feeding, turn off the power switch, clean and maintain the crusher.
The jaw crusher performs well in crushing granite slabs into gravel due to its high efficiency, high yield, and strong applicability. Through reasonable operation procedures and maintenance, the normal operation of the crusher and the high-quality output of gravel can be ensured.
