Low Price Teeth Roll Crusher Used For Metallurgy Coal

Application:                                                                                                                      

Double roller coal crusher (double teeth coal crusher) is widely used in middle and small sized mines for intermediate and fine crashing of the brittle and soft ores of intermediate hardness like coal and coke.

Working principle:                                                                                                            

The particles are drawn into the gap between the rollers by their rotating motion and a friction angle formed between the rollers and the particle, called the nip angle. The two rollers force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rollers.
