Roller crushers, as indispensable crushing equipment in modern industry, play a vital role in numerous industries thanks to their unique structural design and efficient performance. They can handle a wide range of materials to meet diverse production needs, and excel in crushing medium-hardness, brittle materials.

 

Roller Crusher For Processing Materials 

 

Roller crushers are suitable for processing a variety of medium-hardness, brittle materials, including but not limited to limestone, dolomite, gypsum, and coal gangue. These materials maintain a good particle shape during the crushing process, with low overcrushing rates, making them ideal for the production of building materials and chemical raw materials. Roller crushers are also effective for processing coal and coke, reducing large lumps of coal to a particle size suitable for washing or direct use. They also produce minimal pulverized coal, minimizing resource waste and dust pollution.

Recommended Dahua Heavy Industry Roller Crusher

 

1. Toothed Roller Crusher (PGQ Series)

 

Our company's roller crushers primarily include high-performance double-roll crushers, quadruple-roll crushers, and double-toothed roll crushers.

 

Working Principle: Special wear-resistant toothed rollers rotate at high speed to split and crush the material, achieving higher productivity compared to traditional low-speed extrusion methods. The drive mechanism is driven by dual motors via a V-belt, allowing the rollers to rotate in opposite directions to crush the material. Suitable for fine crushing of materials such as steel slag and manganese oxide.

 

Advantages: Simple structure, easy maintenance, adjustable discharge gap, and low operating costs.

 

2. High-Pressure Roller Mill (DHM Series)

 

Working Principle: Hydraulic cylinders and accumulators apply constant high pressure to opposing crushing rollers, achieving efficient fine and ultra-fine crushing of materials. Widely used in construction aggregates, mining, metallurgy, and other fields, it is particularly suitable for processing hard rock and metallurgical slag.

 

Feed size: 18-36mm.

 

Roller speed: 21.1-30.1rpm.

 

Production capacity: 70-630t/h (such as the DHM series steel slag-specific model).

 

Applicable Materials: Hard rock, extra-hard minerals, and metallurgical slag, producing a finer product size.

 

Technical Features: Automatically adjusts the roller gap to maintain constant crushing force and improve product shape; highly wear-resistant alloy roller liners offer a long lifespan without requiring machine disassembly and replacement; and the hydraulic control system includes iron overload and overload protection.
