Detailed explanation of the gap adjustment method of jaw crusher

1. Overview of jaw crusher

The jaw crusher is a commonly used crushing equipment, widely used in construction, highway, railway, water conservancy and other engineering fields. It consists of a body, feed port, discharge port, rotor, impact plate and other parts, and relies on high-speed rotating rotors to crush materials. Its crushing is relatively fine, suitable for crushing processing in industries such as ore, cement, chemicals, and building materials.

2. Preparations before adjusting the crusher

Before adjusting the gap of the jaw crusher, the following preparations need to be made:

(1. Confirm that the machine is in a shutdown state, and the power and gas are cut off;

(2. Install protective covers and safety protection equipment to ensure personnel safety;

(3. Prepare tools, including reflectors, rulers, screwdrivers, etc.;

(4. Confirm the location of the gap adjustment.

3. Steps to adjust the gap of the crusher

01. Adjust the gap of the lower shell

(1) Remove the screws of the lower shell, reverse the lower shell, and place the inspection roller on its inner side;

(2) Use a reflector to check the roller gap and adjust the base screws. The initial adjustment range is generally 0.1-0.3mm, which is adjusted according to the manufacturer's requirements;

(3) After the adjustment is completed, use a ruler to measure the roller gap to see if it meets the requirements.

02. Adjust the gap of the upper shell

(1) Remove the screws of the upper shell, reverse the upper shell, and place the inspection roller on its inner side;

(2) Use a reflector to check the roller gap and adjust the base screws. The initial adjustment range is generally 0.05-0.15mm, which is adjusted according to the manufacturer's requirements;

(3) After the adjustment is completed, use a ruler to measure the roller gap to see if it meets the requirements.

4. Precautions

(1. When adjusting the gap of the crusher, pay attention to the safety of the machine to prevent accidental injuries;

(2. The adjustment of the crusher gap should be continued until it is stable to avoid failures and safety hazards in production;

(3. After each gap adjustment, the error material should be cleaned up in time to avoid affecting the crushing effect;

(4. Before adjusting the gap of the crusher, you should check the instructions and operation manual and follow the manufacturer's operating requirements.

[Conclusion]

As an important mining machinery and equipment, the jaw crusher needs to be constantly maintained and repaired. Adjusting the gap of the crusher is one of the important steps. This article introduces the specific operation methods and matters that need to be paid attention to to help users better perform machine maintenance and repair work.
