Customized Double Roller Crusher 1TPH-200TPH Two Roll Crusher

Double Roller Crusher

1.Product Introduction

The double-roll crusher is a mechanical device that crushes materials by applying pressure through two sets of counter-rotating rollers. It is primarily used in industries such as coal, metallurgy, mining, chemicals, and building materials, and is widely applied in the medium and fine crushing stages of medium to low hardness materials.

2.Application

Its applications are extensive, primarily covering the following fields:

• Mining and Mineral Processing
  As the initial stage of mineral processing, crushing ore to the required particle size.

• Building Materials and Metallurgy
  Crushing construction materials such as sand and stone, or reducing material particle size to meet processing requirements.
• Coal Industry
  Particularly suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants.
• Other Fields
  Applicable in cement, chemical, power, and other industries for coarse and medium crushing of brittle materials. Suitable materials include river pebbles, limestone, iron ore, quartz sand, potassium feldspar, and various other raw materials.

3.Working Principle

The double-roll crusher primarily consists of rollers, support bearings, a compression adjustment mechanism, and a drive unit. Its core operating principle involves two cylindrical rollers rotating in opposite directions. Material is drawn into the crushing chamber formed between the rollers through friction, where it is crushed by compression and shearing forces. ‌The discharge particle size is controlled by adjusting the gap between the two rollers: the wedge device alters the gap size by raising or lowering the wedge block via an adjustment bolt, while the shim device achieves adjustment by adding or removing shims or varying their thickness.‌ When encountering excessively hard or non-crushable objects, the movable roller automatically retreats under spring or hydraulic force, increasing the gap to expel the foreign object and providing overload protection.‌

4.Advantages

• Simple and reliable structure
  Compact equipment design ensures easy operation and convenient maintenance.

• Controllable crushing size
  Adjusting the roller gap regulates maximum product particle size, achieving uniform particle distribution with low over-crushing rates.

• High crushing efficiency
  Features a large crushing ratio (up to 5-8), effectively reducing materials to smaller particles.

• Low operating costs
  Reliable operation, low noise levels, and easy maintenance. The tooth roller crusher also boasts low energy consumption and relatively low wear rates.
• Protective features
  Equipped with overload protection devices that automatically respond to non-crushable objects, safeguarding equipment integrity.
