Working Principle

Working Principle of High Pressure Roll Mill

The gap between the two rolls of the machine can be freely adjusted from 1 mm to 20 mm. Once the roll gap is preset, the crushing particle size can be reliably controlled, and all materials are discharged from the lower part of the crushing chamber at the ideal particle size.

The High Pressure Roll Mill can be used for sand making from the following materials:

It can produce sand from over 200 types of materials, including river pebbles, cobblestone, bluestone, quartzite, volcanic rock, iron ore, weathered rock, limestone, granite, sandstone, marble, and gypsum.

Materials Suitable for High Pressure Roll Mill in Sand Making

The High Pressure Roll Mill is suitable for fine crushing in mineral processing:

Fine crushing of various ores, including gold ore, silver ore, tungsten ore, tin ore, magnetite, copper ore, manganese ore, lead-zinc ore, iron ore, graphite ore, chromite, phosphate ore, metallurgical silicon, etc.

Materials Suitable for High Pressure Roll Mill in Mineral Processing

The double roll sand making machine process flow:

The double roll sand making machine can be used as sand making equipment in sand production lines without wear parts, and also as fine crusher in mineral processing lines to crush metal ores, achieving doubled output.

High Pressure Roll Mill and high-pressure High Pressure Roll Mill on the production site

In sand production applications：

The High Pressure Roll Mill is used as a sand making machine, offering advantages such as no wear parts, low maintenance cost, adjustable sand particle size, high output, and excellent sand particle shape, making it widely used in the sand making industry.

Application of High Pressure Roll Mill in Sand Making

In mineral processing applications：

The High Pressure Roll Mill or high pressure grinding roll (HPGR) is used for fine crushing. They are typically located upstream of the ball mill, capable of crushing ore particles of 2-3 cm down to below 1 mm, thereby significantly improving the operating efficiency of the ball mill and increasing overall production capacity.

High Pressure Roll Mill in Mineral Processing Applications

High Pressure Roll Mills are available in large, medium, and small models. The following is a classification based on different models:

Three models of High Pressure Roll Mill

1. Small spring High Pressure Roll Mills, such as models 2PGT400×250, 2PGT400×400, and 2PGT610×400, with an hourly output of approximately 2-20 tons. These models are ideal for investment and use in small and medium-sized sand plants.

2. Medium spring High Pressure Roll Mills, including models 2PGT750×500 and 2PGT800×600, with an hourly output of 10-50 tons.

3. Medium hydraulic High Pressure Roll Mills, such as models 2PGY750×500, 2PGY800×600, 2PGY800×800, and 2PGY1000×800, producing 20-80 tons per hour. These hydraulic models are more intelligent, offer higher output, and save costs.

4. Large flagship series CNC hydraulic High Pressure Roll Mills, including models 2PGY1000×1000, 2PGY1200×1200, 2PGY1500×1000, 2PGY1800×1000, and 2PGY2000×1000, with an hourly output of 80-400 tons. These models are suitable for medium and large sand plants.
