The definition and types of shredders and pulverizers and their working principles

Definition of shredder and pulverizer:

Shredder: A shredder is a mechanical device specially used to shred and break large pieces of materials, waste or other irregularly shaped items. It usually uses one or more pairs of rotating blades, hammers or other crushing tools to tear, cut or crush raw materials through high-speed rotation to make them easier to handle, transport or recycle.

Pulverizer: A pulverizer is a piece of equipment used to break materials into smaller particles or powder. It can crush raw materials through mechanical force, electric power or hydraulic force, using rotating blades, hammers, rollers and other tools. The purpose of a grinder is to make raw materials easier to handle, transport, store or process, and are widely used in waste treatment, recycling, food processing, pharmaceutical manufacturing, chemical industry and other fields.

working principle:

How the shredder works: The shredder shreds raw materials into smaller pieces through rotating blades or hammers. The material is usually located in the feed area of the shredder, where the rotating blade or hammer rotates or vibrates at high speed to tear and cut the raw material into smaller parts. The shredded materials are discharged through the discharge port, and the size of the discharge port can be adjusted as needed to obtain fragments of different sizes.

How the pulverizer works: The pulverizer squeezes, impacts or cuts the raw materials through rotating blades, hammers or rollers to break them into smaller particles or powder. The raw materials are put into the feed port of the crusher, and after passing through the crushing area, the resulting powder or granules are discharged through the discharge port. The design and working principle of grinders vary according to different types and uses, and can be adapted to different types and sizes of raw materials.

There are many types of shredders and grinders, and their design and purpose vary depending on the type of material being processed and the target particle size. Here are some common types of shredders and shredders:

Types of shredders:

Single-shaft shredder: Uses a blade or hammer on a single rotating shaft to shred, suitable for processing larger materials, such as abandoned cars, furniture, etc.

Dual-shaft shredder: Contains two rotating shafts, each with a blade or hammer, providing stronger shredding power and suitable for scrap metal, waste wood, etc.

Four-axis shredder: It has four rotating axes, providing higher shredding efficiency and stability, and is usually used to process waste electronic equipment, etc.

Types of crushers:

Jaw crusher: Uses the squeezing force between two jaw plates to break materials into smaller particles, suitable for harder raw materials.

Hammer crusher: Uses a rotating hammer head to impact materials to break them into particles. It is widely used in ores, construction materials and other fields.

Cone Crusher: Materials are squeezed and crushed through a cone-shaped crushing chamber, suitable for medium-hardness materials, such as ores, rocks, etc.

Roller crusher: It consists of two or more rollers and crushes materials into particles through extrusion. It is suitable for processing soft materials such as coal, fly ash, etc.

These machines can be customized and adjusted according to the needs of different fields to accommodate different types and sizes of raw materials, providing an efficient and precise shredding or crushing process.
