The chassis of the crusher is an important part of the crusher, and it undertakes the important task of supporting and stabilizing the equipment. However, due to long-term use, material aging or external impact, chassis breakage is a common problem. This article will introduce the treatment methods of the broken chassis of the crusher to help you solve the problem in a timely and effective manner and ensure the normal operation of the equipment.

1. Stop the machine immediately

When the chassis of the crusher is found to be broken, the operation of the equipment should be stopped immediately to avoid further loss. At the same time, notify the relevant personnel to handle it on site.

2. On-site inspection

After the shutdown, conduct a comprehensive inspection of the crusher to understand the cause and extent of the chassis breakage. If necessary, the equipment can be disassembled for further inspection.

3. Formulate a treatment plan

According to the results of the on-site inspection, formulate a corresponding treatment plan. Generally speaking, chassis breakage can be divided into two situations: partial breakage and full breakage. In case of partial breakage, welding, grinding and other methods can be used for repair; in case of full breakage, a new chassis needs to be replaced.

4. Implement the treatment plan

Repair or replace the chassis of the crusher according to the formulated treatment plan. During this process, attention should be paid to ensuring the stability and safety of the equipment.

5. Trial operation and debugging

After repairing or replacing the chassis, trial operation and debugging should be carried out to ensure that all indicators of the equipment meet the requirements. If there are any abnormal conditions, adjustments and processing should be made in time.

6. Re-entry into production

After the above steps, the problem of broken chassis of the crusher is solved and it can be put into production again. During the production process, the maintenance of the equipment should be strengthened to prevent similar problems from happening again.

There are many industries in the industrial field that are developing rapidly with the social and economic growth, such as construction, roads, railways, water conservancy, etc. These industries have driven the demand for sand and gravel, so sand and gravel plants are currently ideal investment projects. When many users understand the sand and gravel production line, they have many questions about the configured equipment, such as jaw crusher (referred to as jaw crusher). The operation process of the sand and gravel production line is feeding-primary crushing-secondary crushing-screening. Among them, the equipment selected in the primary crushing stage is basically jaw crusher. Why is this? Can't other equipment be selected? Let's analyze the specific advantages of jaw crusher and its unique application.

The "charm" and irreplaceability of jaw crusher

The jaw crusher has a history of more than 100 years since its birth. It can now be widely used in major industries such as mining, sand and gravel, and building materials. It itself has a certain irreplaceability. Let's look at it from the following aspects.

1. Working method

Each type of crusher has a different working method, resulting in different applicable materials and scopes. The working method of the jaw crusher is a driven extrusion type. The movable jaw plate and the fixed jaw plate of the crushing chamber form an angle. Driven by the motor, the movable jaw moves up and down, and the angle with the fixed jaw plate changes back and forth, thereby achieving the effect of crushing the material. The structure is relatively simple, but the crushing force and crushing ratio are both large. It is suitable for processing materials with high hardness and large particle size. As we all know, the particle size of general ores is large after being mined.

Jaw crusher is a commonly used crushing equipment used to crush large pieces of stone and other materials into smaller particles. However, in the process of using jaw crusher, sometimes there will be problems of jamming and failure to discharge, which will cause the equipment to fail to work properly and affect production efficiency. This article will discuss the reasons for jaw crusher jamming and failure to discharge, and provide corresponding solutions.

I. Causes of jaw crusher jamming and failure to discharge

1. Material is too hard or too large: Material is too hard or too large is a common cause of jaw crusher jamming and failure to discharge. When the hardness of the material is too high or the particle size is too large, the crushing capacity of the jaw crusher is difficult to meet the crushing requirements, resulting in material accumulation in the crushing chamber, forming a jamming phenomenon.

2. Equipment design problems: Design problems of the jaw crusher may cause jamming and failure to discharge. For example, poor matching between the jaw plate and the toggle plate, incorrect dimensions of the jaw plate and the toggle plate, unreasonable position of the tooth seat, etc., may all lead to jamming and failure to discharge.

3. The transmission belt is loose or worn: The transmission belt is the power source of the jaw crusher. Its looseness or wear will affect the normal operation of the jaw crusher. When the transmission belt is loose, the driving ability of the motor will decrease, affecting the crushing effect; when the transmission belt is severely worn, it will increase the resistance during the transmission process, causing the material to accumulate in the crushing chamber, resulting in a jam.
