G Series High-Pressure Grinding Rolls

Product Description

G Series High-Pressure Grinding Rolls


G Series High-Pressure Grinding Rolls are suitable for fine and ultra-fine crushing of materials with a compressive strength not exceeding 250MPa and humidity below 8%.

Featured by simple structure, reliable performance and low over crushing ratio, these rollers are applied in the sand-making industry and useful for adjusting machined sand fineness modulus.

The materials can be put into production by high pressure grinding rollers only after irons and impurities are removed from them.


Working Principle


G Series High-Pressure Grinding Rolls is mainly composed of two rollers which rotate in opposite directions.

The materials enter the two highly wear-resistant rollers with the same size through the feeding device. Press the materials into compact pies, which are crushed into particles with requisite size and discharged through a hopper. In the next step, the material pies are further dispersed or ground into powder.

 

G Series High-Pressure Grinding Rolls Features


Hydraulic Protection System

The hydraulic system makes it more convenient and easier to adjust roll gap while protecting safety of the whole machine;

High Yield And Low Energy Consumption

The productivity of grinding system increases by 20% to 30%, and power consumption declines by 15% to 35%. Energy consumption is reduced by more than 20% as a whole. Hence, the economic benefits are substantial.

Occupation Of A Small Area

With compact structure and high reliability, the roller occupies a small area and can be flexibly configured.

Longer Service Life Of Roll Surface

The roll surface of the high pressure grinding roller is made of alloy steel embedded with hard alloy studs or cast high manganese steel. This significantly extends service life of the roll surface, which is up to more than 20,000 hours at maximum;

High Environment-Friendliness

The use of roller cover reduces dust pollution and increases environment-friendliness;

Low Maintenance Cost

The simple and reliable structure makes it convenient to replace parts and accessories. It reduces maintenance costs.

Q: What are High-Pressure Grinding Rolls (HPGR)?

High-Pressure Grinding Rolls (HPGR) are advanced crushing equipment that uses two counter-rotating rolls to apply high pressure and compress materials into smaller particles. G Series HPGR is designed for fine and ultra-fine crushing applications, featuring high efficiency, low energy consumption and reliable performance for sand making, mineral processing and material reduction.

Q: What materials can G Series HPGR process?

G Series High-Pressure Grinding Rolls are suitable for processing materials with a compressive strength of up to 250 MPa and moisture content below 8%. Typical applications include: Hard rocks Sand-making materials Mineral materials Aggregates Other materials requiring fine crushing Before feeding into the HPGR, materials should be screened to remove iron and impurities to ensure stable operation and extend equipment service life.

Q: What are the advantages of High-Pressure Grinding Rolls compared with traditional crushing equipment?

Compared with traditional crushing equipment, HPGR provides more efficient size reduction through high-pressure compression crushing. Key advantages include: Lower energy consumption Higher processing capacity Reduced over-crushing ratio Improved material utilization Lower maintenance costs The compact structure and high reliability of G Series HPGR make it suitable for large-scale crushing and material processing applications.

Q: What applications are G Series High-Pressure Grinding Rolls used for?

G Series HPGR is widely used in applications requiring fine crushing and particle size optimization, including: Manufactured sand production Aggregate processing Mineral processing Fine crushing systems Large-scale material processing projects It can also help adjust the fineness modulus of manufactured sand and improve the quality of final products.

Q: How do I choose the right HPGR model for my project?

The selection of High-Pressure Grinding Rolls depends on several factors, including: Material characteristics Feed particle size Required processing capacity Final product size requirements Production conditions Dahongli provides professional equipment selection and customized crushing solutions based on project requirements. Our engineers can recommend suitable HPGR models and integrate them into complete crushing and screening systems.
