Limestone machine

Limestone machine general introduction:

Mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production.

Limestone machine working principle:

This limestone machine 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.

Limestone machine main features and benefits:

Some major advantages of limestone machine are that they give a very fine product size distribution and they produce very little dust or fines. Limestone machine 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. Except limestone, coal is probably the largest user of this machine. Usually, these crushers will have teeth or raised forms on the face of the roll. (Limestone crushers used for minerals and metal ores have smooth faced rolls.)
