Unique structure features of roll crusher

There are many kinds of minerals. Based on the nature of mineral and industry uses, ores are classified into metal ore, nonmetalliferous ore and flammable machine rock. According to the types of metal containing, ores can be divided into the single metal ore, multi-metal composite ore. Ore mining usually through the following steps: crushing and screening, grinding and classification, material separation, concentrates and residue processing, dressing conduction, etc.
Crushing and screening equipment
At present, the medium and small ore mining factories adopt second paragraph or three-stage crushing process; Large scale ore mining enterprises adopt three-stage crushing process; As the block of undressed ore is too big, some large factories also use four sections of broken open process. The typical crushing and screening equipments in ore mining plant are jaw crusher, impact crusher.
Unique roll crusher structure
First of all, driving system works like this: two motors drive rollers through triangle belt transmission. The two rolls force the ore particles between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls .
Secondly, the granularity out of the equipment can be adjusted. The particles are drawn into the gap between the rolls by their rotating motion, a wedge block formed between the rolls and the particle, called adjusting device. Adjustment bolts are fixed on the top of wedge block. When bolts pull wedge block up, the wedge block push moving roll away from fixed roll, the gap become bigger, and the discharging granularity become bigger. And vice versa.
Finally, the transmission part should be installed safety cover by actual requirements for safety.
The growing sophistication of biological science and technology provides another big platform for Henan dressing equipment and mining equipment companies, we believe that theseroll crusher manufacturers and impact crusher manufacturers will seize the opportunity to create another brilliant!
