The machinery manufacturing methods of Hongxing roll crusher and jaw crusher has always been a mystery in machinery manufacturing industry. Hongxing roll crusher has been awarded three national patents. Now, let Hongxing experts share their patent technology with us.
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..
Finally, the transmission part should be installed safety cover by actual requirements for safety.
Double roll crusher introduction
Double roll crusher has teeth on the face of the roll, and it is designed with high capacity. The connecting method about motor and speed reducer adopts hydraulic coupler. The equipment is mounted with overloading protective device to ensure operation. The gap width between the rolls can be changed by hydraulic adjustment system.
The equipment featured with small volume, big reduction ratio (5~8), low noise, high output, high crushing efficiency and convenient maintenance, etc. It is suitable for crushing minerals in mining industry, metallurgy industry, building industry and so on.
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.
The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotate inward simultaneously. The materials are extruded, crushed and ground, then the end products comes out from the bottom of this crusher.
