Polygonmach Crushing, screening, and washing plants utilize a variety of different types of equipment based on the specific needs of the operation and the type of material being processed.

Crushers: Polygonmach Crushers are used to reduce the size of the raw material that is being processed and are often the first step in a multi-stage process. Different types of crushers are used for different types of materials and specific applications. Some commonly used types of crushers include:

  1. PJC Jaw Crusher: A heavy duty machine that uses compressive force to crush rocks into a fine gravel.
  2. PC Cone Crusher: It utilizes a rotating piece of steel against a stationary piece of steel to reduce material. It is often used for secondary or tertiary crushing.
  3. PPI Impact Crusher: Uses impact to crush materials. This can be used for primary, secondary, or tertiary crushing.
  4. PVSV Vertical Shaft Impact Crusher: A type of impact crusher that uses a high speed rotor with wear resistant tips.

PVS Screeners: After the material has been crushed, screeners are used to separate the crushed rock into various sizes. Different types of screeners used include:

  1. Vibratory Screens: These machines use vibration to separate and move large quantities of dry materials like rock, gravel, and sand into different sizes.
  2. Rotary Screens: These use a rotating cylindrical screen to separate and size material.
  3. Grizzly Screens: These are heavy-duty screens that are used to handle large rocks before they are fed into the primary crusher.

Polygonmach Washers: After the material has been crushed and sized, it is often washed to remove any dust, dirt, or impurities. There are several different types of washers:

  1. Coarse Material Washers: Used to remove a limited amount of dirty material from a coarse aggregate.
  2. Fine Material Washers: Also known as sand screws, used to wash, classify, and dewater smaller particles.
  3. Log Washers: Ideal for scrubbing difficult materials such as tough insoluble clays, conglomerates, soft stone, and cemented aggregate.

The choice of equipment will depend on the nature of the raw material and the desired size and quality of the final product. Different types of crushers, screeners, and washers may be combined in a single plant to achieve the desired result.

The selection of crushers, screeners, and washers largely depends on the type of raw material, the size of the input material, the desired output size, and the final application of the product.


  1. Vibrating Inclined or Horizontal Screens: Suitable for a wide range of materials, including rock, gravel, sand, and others.
