Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive. As a most commonly used equipment, roll crusher has high developmental potentials in mining industry.
With the advent of spring, the infrastructure construction in our country has also experienced fast growing. Therefore, the need of construction materials increases with each passing day, which makes crushing machines pillar equipment in this industry.
Firstly, from a historic point of view, it has a long history of more than two hundred years. It is also named double roll crusher invented in 1806. With the advance of science and technology, the national famous crushing enterprise Hongxing Machinery integrates the advanced technology at home and abroad and develops roll crushers which are widely applied in electric, mental, mining, port construction, grain storage, chemical industry, etc. This machine is characterized with reasonable structure, sophisticate parts, high yield, low consumption and easy operation.
Secondly, it is simple in structure which makes it high efficient and energy saving. This series of roll crushers are mainly composed of the roller, the roller support bearings, compacting and regulating devices and drive components. Hongxing roll crusher has reasonable structure with low operational cost and high yield. For instance, the grinding roller is equipped with replaceable wear liner, wear-resistant linings which adopt domestic advanced wear-resistant materials. It has a long life and is difficult to damage, easy to maintain.
Thirdly, the crusher can do both crushing and grinding work. This is because the smooth surface of rollers in roll crusher. As the raw material enters the crushing chamber, it has to bear the crushing of turning the roller axis and is compelled to go through the two rollers. Meanwhile, the material is squeezed and grinded and begins to crack. Therefore, the small particles that satisfy the required size are thrown out of the machine while some larger particles are driven back to the crushing chamber to re-crush until they reach the required size.
Fourthly, this crushing machine is a good company in coal mining industry. Roll crusher can not only be widely used in cement producing, mental processing, electric and coal mining industry to process fragile and hard raw materials, but also be used in ore beneficiation and construction industry to crush mineral rocks with medium hardness.
