2GYP Hydraulic Roller Crusher

Hydraulic roller crusher adopts two horizontally arranged rollers rotating in opposite directions, dynamically adjusting the pressure and gap between rollers (usually 1-20mm) through hydraulic system, utilizing high-pressure extrusion and shear force to crush the materials, and the finished products are in the form of cubic shape with even particle size (low over-crushing rate), suitable for medium and fine crushing of medium and low hardness materials, such as coal, limestone, iron ore, etc. The advantages of this roller crusher include high precision of full hydraulic control, automatic protection, convenient adjustment of discharge, and support for wet material processing, which is widely used in the fields of mineral processing, building materials, refractory materials and so on. Its advantages include high precision of full hydraulic control, automatic protection, convenient adjustment of discharged material, and support for wet material processing, which is widely used in the fields of mineral processing, building materials, refractory materials and other fields of the demand for precise regulation of particle size.


Product Advantage

Product Advantage

1. Precise particle size control

   Through the hydraulic system to dynamically adjust the roller gap (1-20mm), the output particle size is uniform and can be accurately set, with a low rate of over-crushing (powder accounted for less than 5%), especially suitable for the finished product particle uniformity requirements of the scene, such as coke crushing, concrete aggregate preparation.  


2. Energy efficient

   Low energy consumption: the hydrostatic crushing principle reduces useless impacts, reducing energy consumption by 20-30% compared with traditional crushers;  

   High productivity: double rolls rotate in opposite directions at high speed, the processing capacity can reach 5-300 tons/hour, with strong continuous operation capability.  


3. Strong adaptability

   Moisture tolerance: it can handle sticky and wet materials with moisture content ≤15% (such as lignite and sludge), and the anti-clogging design guarantees continuous operation;  

   Hardness coverage: applicable to medium and low hardness materials (Mohs hardness ≤ 5), covering coal, limestone, gypsum and other diversified raw materials.  

4. Intelligent and reliable  

   Overload protection: the hydraulic system automatically senses abnormal pressure and instantly releases the roller gap to avoid equipment damage;  

   Automation integration: support PLC control, real-time monitoring of roller pressure, temperature and other parameters, to achieve unattended and fault warning.  


5. Convenient maintenance  

   Modular design: core components such as rollers and bearings can be quickly disassembled and replaced, reducing downtime;  

   Long-life components: the roller surface is made of high chrome alloy or surfacing wear-resistant layer, which extends the service life by 2-3 times compared with ordinary materials.  


6. Environmental protection and low noise

   Closed structure: inhibit dust spillage, supporting dust removal interface is easy to dock the environmental protection system;  

   Low vibration noise: operating noise <85dB, in line with the environmental standards of industrial places.  


7. Multi-functional expansion  

   Multi-purpose: By replacing the roller surface texture (tooth, groove, etc.), it can be adapted to the needs of coarse crushing, fine crushing or material shaping;  

   Flexible layout: supports fixed or mobile installation, adapting to various scenarios such as mines and construction sites.  

These advantages make it an ideal choice in the fields of coal sorting, cement production, metallurgy and coking, and solid waste recycling, taking into account efficiency, cost and environmental protection.

Working Principle

Working Principle

Hydraulic double roller sand making machine mainly utilizes triangle belt or universal joint coupling to transfer and adjust the gap between the rollers. The material enters evenly between two horizontally parallel arranged rollers through the feeding device, and the rollers rotate in opposite directions driven by the hydraulic system, and the material is subjected to initial extrusion and friction in the nipping area of the rollers to form pre-crushing. When encountering extremely hard or unbreakable materials, the rollers can automatically retreat under the action of the hydraulic cylinder, thus reducing the gap between the two rollers. After the gap becomes larger, the hard or unbreakable material falls naturally to ensure that the machine will not be damaged. There is a specific gap between the two oppositely rotating rolls. By changing the gap, the product discharge size can be controlled.
