Advantages

1、Flat roll surface model is suitable for the fine crushing operation with feed size less than 80mm and finished product size 0.5-10mm, such as the use of cobblestone, construction waste artificial sand; mining industry, fine crushing of iron ore, quartzite; ceramics industry, crushing of raw materials; metallurgical industry, crushing of coke, quicklime; coking plant, fine crushing of coal powder; chemical industry, crushing of all kinds of raw materials and so on, or crushing occasions similar to those mentioned above.

2、The roll face model is suitable for the medium and fine crushing operation with the feed size less than 150mm and the finished product size 3-30mm. Such as cement industry mill before pre-crushing cement clinker, limestone and composite materials; coal water slurry industry into the mill before the pre-crushing coal; iron ore industry into the mill before the pre-crushing steel slag, iron ore, silica ore; brick factory crushing all kinds of ores to do free-burning bricks; thermoelectric power plant crushing coal; or with the above similar crushing occasions.

Working Principle

Roller grading machine is the use of two high-strength wear-resistant alloy crushing rolls, the relative rotation of the high squeeze to crush the material, the material enters the gap between the two rolls (V-type crushing chamber), by the relative rotation of the two crushing rolls of the squeeze and shear force, in the squeezing, shear and under the crushing of the material into the required particle size from the discharge port discharge.

Application Area

Roll crusher is a kind of crushing equipment which is widely used in the industrial field, and its application fields mainly include the following aspects:

Mines and Quarries: Roll crusher is widely used in mines and quarries for crushing various ores and stones. It can crush large raw materials into the required size for subsequent processing and utilisation.

Construction and infrastructure: In the construction and infrastructure sector, roll crushers are commonly used to crush materials such as concrete, bricks and stone. It can crush waste construction materials into reused gravel for road construction, filler materials and other uses.

Metallurgy and Chemical: In metallurgy and chemical industry, roll crusher is commonly used to crush various ores, slag and chemical raw materials. It can crush raw materials into the required particle size for subsequent smelting.

Energy and environmental protection: In the field of energy and environmental protection, the roll crusher is commonly used to crush materials such as tailings and sand return materials, which can be crushed into suitable particles and improve the efficiency of energy utilisation.

Sand making plant, chemical plant, electric power, coal, construction, water conservancy engineering, highway engineering and other various fields: roll crusher will be used in these fields to complete the fine crushing operation of materials.
