Jaw Crusher Troubleshooting Guide: From Cause to Solution-Vanguard Machinery Tech

 Jaw crusher, also known as jaw stone crusher, is mainly suitable for crushing various ores and rocks with medium hardness and below. It is widely used in industries such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical engineering. When using a jaw crusher, it is necessary to comply with relevant safety operating procedures, regularly inspect and maintain the equipment, and periodically replace wearing parts to ensure that the equipment operates normally and stably.

Common causes and solutions for jaw crusher faults are as follows:

1. Failure phenomenon: feed inlet blockage.

Failure reason 1: Excessive or uneven feeding, resulting in material blockage at the feeding port.

Solution: To avoid excessive input at one time, control the reasonable amount of material input. Adjust the feeding method to ensure that materials are fed evenly.

Failure reason 2: It can also easily cause blockages at the feeding inlet when the feeding material is too large or too hard

Solution: The materials are coarsely crushed or screened in advance to make them meet the processing capacity of the jaw crusher; If the material has a higher hardness, you can consider using more wear-resistant jaw plates and hammerheads.

Failure reason 3: The design of the feed port is unreasonable. The width of the feed port is too small or the shape is not suitable for material flow, which can also easily cause blockage.

Solution: Optimize the design of the feed port to ensure appropriate width and smooth shape, which is conducive to the smooth flow of materials; Clean the feed port regularly to avoid clogging due to long-term use.

2. Failure phenomenon: The jaw plate is loose or damaged

Failure reason 1: The fixing bolts of the jaw plate are loose, causing the overall jaw plate to become loose.

Solution: Check the condition of the jaw plate fixing bolts and tighten them to the specified torque; Regularly check the tightening condition of the jaw plate fixing bolts, and tighten them in time if they are found to be loose.

Failure reason 2: The jaw plate is severely worn and cannot complete the crushing task normally.

Which Parts of the Impact Sand Making Machine Need to be Replaced Frequently?-Vanguard Machinery Tech

 The sand making machine is suitable for medium and fine crushing various ores and rocks with different hardness levels, providing advantages such as high production efficiency, large reduction ratio, good quality of the final crushed sand, and uniform particle size. It is widely used in industries such as construction, highways, railways, water conservancy, and chemical industry. When using the sand making machine, it is necessary to pay attention to safe operation and follow the instructions and maintenance regulations of the equipment. Regularly inspect and maintain the sand making machine to ensure the normal operation and service life of the equipment. In addition, choosing the type and configuration of the sand making machine reasonably can also improve production efficiency and sand quality.

The following components of the impact sand making machine may need to be replaced frequently during use:

The throwing head rotates at high speed, collides with the feed material and generates impact on the force. Therefore, it is necessary to frequently check and replace worn or damaged ejection heads during use.

2. Impeller: The impact block is fixed on the crushing plate of the impeller, typically made of wear-resistant materials, and has strong impact resistance and wear resistance. When the raw material passes through the crushing cavity, the impact blocks are crushed by the impact force. During long-term use, the impact block will lose its crushing ability due to wear and tear, therefore it is necessary to timely replace the worn impact block to ensure the normal operation of the sand making machine.

3. Distributing tray: The distribution tray is usually located above the feed port of the impact sand making machine. Its function is to evenly disperse the feed material into the crushing cavity. The design of the material distributing tray can adjust the distribution and flow rate of the feed to ensure that the materials are evenly impacted and broken in the crushing cavity. The distributing tray needs to be adjusted and maintained according to the nature of the material and feeding requirements to ensure a good crushing effect.

4. Flow plate: The flow plate is located in the upper and lower parts of the impeller, and plays a role in guiding and protecting the material when it passes through the crushing cavity. The design of the flow plate can control the flow route of the material and avoid excessive crushing or blockage. Due to the impact and wear of materials, the flow channel plate is susceptible to wear and tear, so the worn flow channel plate needs to be checked and replaced regularly to ensure the stable operation and effective crushing of the sand making machine.

5. Peripheral protective plate: The peripheral protective plate is usually fixed on the crushing cavity wall of the impact sand making machine, which can protect the crushing cavity wall, reduce direct impact and wear, and extend the service life of the crushing cavity wall. The design of the surrounding guard plate can affect the flow and collision mode of materials in the crushing cavity, thereby improving the crushing effect of materials and increasing crushing efficiency and capacity. Because the peripheral protective plate is inside the impact sand making machine, it is easily affected by the impact and wear of materials. Therefore, it is necessary to regularly check the wear of the peripheral protective plate and replace worn parts in time to maintain the normal operation and crushing effect of the sand making machine.

When using the impact sand making machine, the operator can understand the equipment operation and maintenance methods and replacement cycle according to the guidance and equipment maintenance manual provided by the manufacturer, ensure the uniform feeding of materials and the normal operation of the crushing cavity, and improve the efficiency of the sand making machine. Production efficiency and sand quality. Under normal circumstances, the replacement cycle of the ejection head and impact block of the sand making machine is generally more than half a month. The distribution tray and flow channel plate are used for a long time, which is 2-3 times that of the ejection head and impact block. The board replacement cycle is approximately one year.

When using an impact sand making machine, follow the operating manual and manufacturer's recommendations to ensure the safe operation of the equipment and operator safety. Here are some common considerations:

1. Follow the operation manual: Before the operation, carefully read and understand the operation manual of the impact sand making machine, and operate the equipment correctly according to the requirements. Do not modify or ignore the operating steps without authorization.

2. Connect the power supply correctly: Ensure that the power supply wiring of the device is correct, the voltage is stable, and the grounding is reliable to prevent electrical faults and the risk of electric shock.

3. Check the wearing parts: Before use, check and maintain the wearing parts of the impact sand making machine to ensure that they are in good working condition.

4. Smooth feeding: When feeding the impact sand making machine, the feeding should be kept even and continuous to avoid overloading to avoid equipment damage or blockage.

5. Pay attention to safety protection: During use, operators should correctly wear personal protective equipment such as safety helmets, work clothes, and protective glasses to prevent dust, splashes, or other hazards from harming personal safety.

6. Regular inspection and maintenance: Regularly inspect key components of the equipment, such as motors, belt drives, bearings, etc., and perform timely maintenance and replacement to ensure the reliability and stability of the equipment.
