PG series Double Roller Crusher for sale

♥ Usage and Application of double roller crusher :

The roll crusher has many advantages such as reliable working condition, simple repair and maintenance, low operational cost and adjustable discharging granularity. According to the number of the rotor, it can be divided into double roll crusher and four-roll crusher, and it has wide application in processing all kinds of crisp and tenacious materials in refractory materials, cement, metallurgy, power station and coal and other industries.

♥ Features of double roller crusher :

Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)

♥ Woring principle of double roller crusher :

A roller crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.
