The series roller crusher can be applied in industrial sectors such as ore dressing ,chemical industry, cement, refractory, abrasive and building materials to break to pieces ores and rocks of various high and medium rigidities, and particularly applied in the building material industry to produce pisolitr and pea gravel, with better effect than ordinary crushers, the series crusher has characteristics of reliable working, simple repair, low operating cost and adjustable marking granularity.

Roll crusher Working principle: 

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.

Feature

1 . Equipment in the grinding system PDG-II to roll crusher, grinding equipment production capacity can be fully tapped , and can increase production by 30% -40 % of the total energy consumption can be reduced by 20 % -30 %.

2 compact structure, light weight, small size , the same capacity for grinding system requirements , equipment PDG-II to roll crusher can save significant investment.

3 simple structure, small footprint, operation and maintenance more convenient .

4 Dust board installed inside , good sealing performance , avoiding the Young tiny splash crushed material , less dust , low noise , greatly improved work environment .

5 . Abrasive roller weight to optimize the design of new equipment does not need to change the use of the mill roll body for life , while old roller machine for one year would need to open repair, replace the roller body .

6 fitted with replaceable wear liners on the roll crusher roller, wear- resistant liner using advanced materials, has a long life , not damaged, and easy maintenance . Life of up to one year of continuous wear serious, remove the lid can be replaced . Small amount of maintenance , and low cost , which is any other type of domestic crushers are unmatched .

7 on the roll crusher equipped with safety guards, when there is an accident metallic iron into the crushing chamber , the guard action, iron leakage normal operation of equipment .

8 abrasive roll crusher roller body roll gap between the 1mm ~ 20mm adjustable , according to the requirements of the particle size after crushing a good tune roll gap , broken particle size can be reliably controlled , all in an ideal particle size discharged from the bottom of the crushing chamber .

9 simple and reasonable structure, low operating cost , smooth operation, high efficiency, high crushing efficiency , the particle size is adjustable.

10. The roll crusher is a low- speed and high pressure rollers squeeze works. Material from falling into the upper vertical crusher crushing chamber , the strong pressure generated by the squeeze between two rollers under the crushing majority of the material has become powdery , granular material inside the remaining small portion has produced a lot of cracks. In the further process of crushing , grinding can greatly reduce energy consumption and improve yield.
