Development: double roll crusher has a development history of more than two hundred years.
Double roll crusher is also called roller crusher which is researched and developed in 1806 and has a development history of more than two hundred years. With the constant advancement of science and technology, Henan Hongxing Mining Machinery Co., Ltd. combines the advanced technology in foreign and domestic market, and the roller crusher manufactured by our company is widely used in power station, metallurgy, mine, wharf, granary and chemistry. This equipment has many advantages of reasonably structure, good manufacturing, high output, low energy consumption and convenient operation. Advanced production and test equipment, strong technical power, mature technology and scientific management provide guarantee for the stability and reliability of product quality and good corporate reputation.
Structure: simple, reasonable, highly efficient and energy saving
This series of double roll crusher is mainly made up of roll wheel, supporting bearing of roll wheel, pressing and adjusting device and driving device.
The double roll crusher of Hongxing Machinery is featured with simple and reasonable structure, low running cost and high efficiency and energy conservancy. On the grinding roller of the equipment, there is changeable anti-abrasion lining board which uses advanced anti-abrasion materials, so this lining board has the advantages of long service life, small abrasion and convenient maintenance. Even when the abrasion is serious, only moving he machine cover can change the lining board, so that the maintenance work is easy and the cost is low.
Working principle: the roller has the effects of both crushing and grinding.
Since the roller of the double roll crusher is smooth, it not only has the effect of crushing, but has the function of grinding. After going into the crushing chamber of the machine, under the cutting force of the rotary roller, the materials are forced to go through the two rollers, and at the same time, under the pressing and grinding of the rollers, the materials will break. The small broken particles will go through the gap between the two rollers along the tangent direction of the rotation of the rollers and are thrown to the lower part of the machine.
Application: double roll crusher is good partner of the coal industry.
Double roll crusher can not only process crisp and tenacious materials in cement, metallurgy, chemistry, power station and coal industry, but crush rocks and ores with below medium hardness in ore beneficiation plant, chemistry, cement, building material and other industrial departments. Especially in the coal industry, when using this crusher to crush raw coal, it is only necessary to remove iron, foreign matters before crushing the raw coal. The crushed materials is even in granularity and low in over-crushing rate, thus simplifying the coal dressing process and reducing the investment and production cost.
