Medium sized powder machine

1、 Basic concepts

It is usually used to crush or grind various materials (such as wood, straw, plastic, etc.) to achieve the desired particle size or shape.

2、 Structural characteristics

Knife disc and blades: The diameter of the knife disc and the number of blades of the crusher usually vary depending on the specific model and purpose. For example, the diameter of the disc of a wood crusher may be 420mm, with 4 blades, used for effective cutting of wood.

Hammer and sieve: Some crushers, such as wood crushers, use a dual crushing function of hammer cutting and high-speed airflow impact collision. Hammer and sieve are their main vulnerable parts, used for fine sorting and processing of materials.

Feed inlet and spindle: The size and shape of the feed inlet are usually related to the type and size of the crushed material, while the spindle speed determines the crushing efficiency

3、 Working principle

Material input: Send the material to be crushed into the crusher through the feeding port.

Crushing process: The material is crushed into the required particle size by the cutting, impact, and grinding action of blades, hammers, or grinding discs inside the crusher.

Screening and output: The crushed materials are screened through a sieve, and the qualified materials are output from the discharge port, while the unqualified materials are returned for further crushing

4、 Application Fields

Wood processing: used to crush wood, branches, bark, etc. into sawdust, sawdust, etc., for use in papermaking, biomass energy and other fields.

Plastic recycling: used to crush waste plastics into particles for easy recycling.

Agriculture and Feed: Used to crush crop straw, grass, etc. into feed to improve feed utilization efficiency.

5、 Maintenance and upkeep

In order to ensure the normal operation and extend the service life of the crusher, regular maintenance and upkeep are required, including:

Check and replace vulnerable parts: Regularly inspect the wear and tear of vulnerable parts such as blades, hammers, and screens, and replace them in a timely manner.

Cleaning and lubrication: Regularly clean the residual materials and dust inside the crusher to keep the machine clean; At the same time, lubricate the lubrication parts to ensure flexible operation of the machine.

Adjustment and Calibration: Adjust the feeding port size, spindle speed, and other parameters of the crusher according to usage to ensure stable crushing effect.

In summary, as an important mechanical equipment, crushers play a crucial role in multiple fields. Understanding its structural characteristics, working principles, and application fields can help to better use and maintain the equipment.
