History Of Double Roll Crusher
Roll crusher appeared in 1806, it has been two hundred years of history. There is a saying called: natural selection of the fittest. Roll crusher after two hundred years of development, but also used by people without being eliminated, we can see its value. On the roll crusher for feed particle size less than 80mm, -20mm finished 50 mesh size requirements of crushing operations, its excellent crushing crushing effect is any one crusher can not be compared. So far on the roll crusher in the crushing industry has a certain influence. After two hundred years of development, the roller crusher is no longer before the kind of heavy, uneven fineness crusher broken up. Roll crusher after many technological innovations and structural transformation, it has crushing more granular, more processing power, simple operation, wide application, long service life, the particle size can be adjusted, unanimously endorsed by the majority of customers and favor.
Roll crusher is also known as a double roll crusher. Shanghai SBM has 30 years of manufacturing experience double roll crusher, regardless of appearance or from the performance are very good. The machine is mainly applied to the chemical, power, cement, metallurgy, building materials, refractories and other industrial sectors crushing medium hardness material, such as slag, coke, limestone, coal, slag and other materials in the debris and crushing operations.
Roll crusher is the use of the roller surface friction material will be crushed into bite, so bear squeeze or split and crusher machinery. Mainly used for material crushing operation. When used in crushing or need to increase the crushing ratio, often make the teeth or grooves in the roll surface to increase the splitting role of this crusher is called double roll crushers. When you need a finer end product, the greater the yield, crushing ratio greater device, use the four-roll crusher.
Double roll crusher suitabled for materials
Roll crusher has reliable, easy maintenance, low operating costs, the discharge grain size is adjustable. Rollers can be divided according to the number of double roll crusher and four roller crusher, according to different forms of the roll surface can be divided into smooth roll crusher and toothed roll crusher .
Double roll crusher can be used for mineral processing, chemical, cement, building materials and other industrial sectors and tertiary crushing all kinds of medium hardness ores and rocks following purposes. Such as: river pebbles, calcite, quartz, marble, pebbles, bentonite, iron ore, bluestone, rocks, slag, limestone, weathered sand, diabase, granite, basalt and so on.
Advantage of double roll crusher
In recent years, double roll crusher is also widely used in crushing slag, through to the roll out of the slag crusher, to a large extent reduces the grinding mill cost and improve the economic efficiency of slag election field. In some manufacturers have adopted the double roll crusher for sand, crushing stone if you are relatively hard, we recommend that you first consider the double roll crusher for crushing. Because wearing parts double roll crusher is rarely, except roll skin, no other wearing parts. However, other crushing equipment at the higher hardness of materials crushing, did not have to change a few days wearing parts, greatly increases the time and economic costs. My company's double roll crusher used in high manganese steel casting roll skin overall, all roll skin have been heat-treated. This produced the roll skin compared to ordinary life and thus produced was prolonged for two to three times.
