How to adjust the roller skin of the briquetting machine

The roller skin of the briquetting machine is an important part of the briquetting machine. It is located outside the roller core of the briquetting machine. It is usually a cylindrical component with a ball socket on its surface. The shape and size of these ball sockets are designed according to the pressed material and the required product shape. The adjustment of the roller skin of the briquetting machine is a key step to ensure the normal operation of the briquetting machine and improve the product quality.

Briquetting Machine Roller Adjustment

1. Adjustment method

Gap adjustment:

The gap of the roller skin determines the filling amount and molding pressure of the material. The appropriate gap can ensure that the material is evenly distributed between the roller skins and avoid molding problems caused by uneven pressure.

The gap between the roller skins is usually adjusted by adjusting the adjusting nut of the machine. The gap size needs to be adjusted according to the nature of the material and the molding requirements. 

In general, the smaller the gap, the denser the molded balls, but too small a gap may cause the equipment to jam or block the material; too large a gap will cause the molding accuracy to decrease.

Parallelism verification:

Use tools and measuring equipment to check the parallelism of the roller skins and make fine adjustments until the two roller skins are completely parallel over the entire length. The guarantee of parallelism helps the material to be evenly stressed between the roller skins and improve the molding quality.

Pressure adjustment:

The pressure of the briquetting machine is usually achieved by adjusting the hydraulic cylinder or mechanical transmission system. The size of the pressure should be adjusted according to the nature of the material and the molding effect. Too low pressure will result in poor spherical quality, while too high pressure may increase the equipment load and energy consumption, and even damage the machine.

Tilt angle adjustment:

The tilt angle of the roller skin is also an important factor affecting the quality of the pressed product. The adjustment of the tilt angle can be achieved by adjusting the height of the roller skin bracket. Generally speaking, the larger the tilt angle, the greater the density and smaller the size of the pressed product. However, it should be noted that the adjustment of the tilt angle should be carried out according to specific production needs to avoid blind adjustment.

Surface treatment:

The surface hardness and smoothness of the roller skin affect the adhesion of the material and the surface quality after molding. If necessary, the surface of the roller skin can be hardened or polished to improve its performance.

2. Precautions

Safe operation: Before adjusting the roller skin, the machine must be shut down and the power must be cut off to ensure that the equipment is in a safe state.

Comply with all safety regulations to prevent accidents.

Keep the machine clean: Keep the machine clean and prevent the adjustment nut and other parts from being disturbed by debris. 

Moderate force: When adjusting the roller skin, pay attention to moderate force to avoid excessive force causing damage to the machine. 

Test verification: After adjusting the roller skin, it is necessary to test to verify whether the adjustment effect meets the requirements. 

This helps to find and solve problems in time to ensure production efficiency and product quality. 

Regular inspection and maintenance: Regularly inspect and maintain the roller skin, including checking the degree of wear, cleaning residual materials and impurities. 

This helps to maintain the normal operation of the equipment and extend its service life. 

Professional operation: Operations such as roller skin adjustment and replacement should be performed by professionals to ensure the accuracy and safety of the operation. 

By following the above methods and precautions, the roller skin of the briquetting machine can be effectively adjusted and maintained to ensure the normal operation of the equipment and improve product quality.
