Corsar R-190 Universal shredder

The Universal shredder is designed for crushing (shredding) by cutting method industrial waste, plant raw materials, and food products, namely: chunks and sheet plastics of all kinds, wood, cardboard and paper, glass, rubber, foam, textiles, animal bones, roots, branches, bark, medicinal herbs, berries, dried fruits, rusks, etc.

In accordance with the type of processed raw materials, the basic model of the shredder can be equipped with an aspiration system for removing light impurities from the shredded product (roots, medicinal herbs, tree bark, berries, etc.) or a pneumatic discharge system for forcibly removing the shredded product prone to doming (foam, film, etc.) from the working chamber.

The base model of the universal shredder (crusher) consists of a frame, on which the following components are mounted:

• housing with a rotor inside;
• receiving hopper;
• electric motor with drive;
• control cabinet.

The feed hopper is designed for loading raw materials and feeding them into the grinding chamber. Depending on the type of raw material, hoppers of various designs can be installed:

• for bulk materials – a standard hopper;
• for voluminous materials – an enlarged hopper with a manual forced feed system.

To feed voluminous low-density raw materials to the working bodies, the shredder can be equipped with a mechanical forced feed unit (feeder).

The housing is a welded construction with three stationary knives mounted on the inner surface. Inside the housing, a rotor is installed on bearing supports, with three movable knives attached to it. A calibration screen is installed in the lower part of the housing, the hole size of which determines the fineness of the shredded product.

The basic model of the shredder is equipped with one calibration screen with hole sizes as required by the customer.

The input material from the feed hopper enters the working chamber, where it is shredded (crushed) between the movable and fixed knives. Particles smaller than the holes in the calibration screen pass through and fall into the discharge chute. Larger particles are carried by the rotor in a circular motion and undergo further shredding.

• The shredder features an adjustable gap between the movable and fixed knives, improving the cutting quality and preventing material from jamming between the knives.
• The rotor is equipped with a flywheel that ensures smooth operation. During the rotor’s idle time, energy is accumulated, which is then used during the cutting process.
• The cutting edges of the movable and fixed knives are positioned at a specific angle to each other, creating a guillotine effect. This significantly reduces the cutting force required and, consequently, the energy consumption. The specific energy consumption of the universal shredder is 0.015 – 0.044 kW/kg.
• The shredder utilizes a minimal number of structural elements, each of which is multifunctional. This design ensures easy maintenance, enhances the reliability and durability of the universal shredder, and provides a compact structure.
• The product line also includes machines whose working parts and internal surfaces are made of stainless materials to meet higher standards for contact with food products.

• Versatility (ability to work with various materials).
• High shredder productivity per unit of power consumed (low energy consumption).
• Absence of impact (cutting) loads.
• Ability to be installed in any production premises without the need for foundation construction.
• Compact design and high reliability.
• High level of ergonomics and accessibility for sanitary and hygienic processing.
• Ability to be upgraded for new emerging production tasks.
