Roll Crusher: Technical Parameters, Working Principles, and Applications | Comprehensive Guide to Efficient Crushing Equipment

The roll crusher is a highly efficient and reliable crushing device widely used in industries such as metallurgy, building materials, and refractory materials. This article provides a detailed analysis of the technical parameters, working principles, features, and application fields of roll crushers, helping you gain a comprehensive understanding of this equipment.

A roll crusher is a mechanical device that crushes materials by using two counter-rotating rollers. It is primarily used for crushing medium-hard and soft materials and is widely applied in industries such as mining, metallurgy, chemicals, and building materials. It is particularly suitable for crushing coal, limestone, cement clinker, and other materials.

The technical parameters of roll crushers are crucial references for users when selecting equipment:

• Feed Size: ≤30 mm
• Discharge Opening: 2-10 mm
• Processing Capacity: 5-110 t/h
• Roller Width: 250-600 mm
• Features: Uniform crushing of materials, simple structure, reliable performance, and cost-effective durability.

The core components of a roll crusher are two parallel cylindrical rollers. The roller surface can be smooth, toothed, or grooved, depending on the material properties.

• Roller Structure:
  • One roller is fixed to the frame, while the other is a movable roller that can move slightly on the frame.
  • The roller surface is covered with special wear-resistant materials to ensure high durability and long service life.
• Crushing Process:
  • Materials enter the crushing chamber through a “choke-fed” method.
  • Materials are compacted under the action of the rollers, reaching 85% of their true density, and are crushed under high pressure.
  • The crushed product has a wide particle size distribution, containing more fine particles, and is discharged in the form of flakes.

Roll crushers offer the following advantages due to their unique design and functionality:

• High Crushing Ratio: An adjustable crushing bar can be installed below the rollers to achieve a larger crushing ratio.
• Simple Structure: Modular design allows for separate or combined installation, facilitating transportation and maintenance.
• Low Over-Crushing Rate: The combination crushing method, as opposed to impact or striking, reduces secondary crushing phenomena, resulting in a lower over-crushing rate.
• Environmental Performance: Low noise and minimal dust emissions comply with environmental requirements.

Roll crushers play an important role in various industries, including:

• Metallurgical Industry: Used for crushing coke, sintered ore, etc.
• Building Materials Industry: Used for crushing limestone, cement clinker, and other construction materials.
• Refractory Materials: Used for crushing raw materials for refractory products.
• Environmental Industry: Used for processing construction waste and scrap materials, enabling resource recycling.
