Structural features of HPGR:
1. New type stud roll surface technology
It adopts high-quality hard alloy studs with high hardness and good wear resistance. The stud arrangement is designed by computer simulation, and the arrangement is reasonable, which can form a uniform material layer between the studs, effectively protecting the studs and roll surfaces, and improving the service life of squeezing roll. The studs are installed with imported special adhesives for easy replacement.

Separation technology of roll bushing and main shaft
The main body of the squeezing roll is made of high-quality forged steel, and the roll bushing is forged with high-quality alloy steel. The main shaft and the rolls are made of different materials, which improves the toughness of the main shaft and the rigidity of the roll bushing. The service life of the shaft bushing is greatly improved. The replacement of the roll bushing is convenient.

Bearing quick mounting and dismounting technology
High-quality tapered hole bearings are adopted and high pressure oil tank is preformed. The bearing can be easily dismounted through high-pressure oil pump, greatly reducing the difficulty of replacing the bearing and improving the maintenance efficiency.

Multiple combined sealing technology
The bearing seal adopts a variety of J-type plus V-type and labyrinth seals, and the combined sealing technology effectively ensures the sealing effect of the bearing.
