Blind Drilled Press Roll For Paper Mill
Description:
Blind drilled press roll is an important part for paper machine. Drilling surface covered with a hole diameter of 2mm, 12-15mm deep blind hole. Can also drill different shades of blind holes between two rows of white, blind hole press roller opening rate of about 25% to 30%, the eyelet volume than about 5 times the pressure roller, it can accommodate more press water.
Specification:
1. Material: The roller is made of cast steel(iron)and the surface is covered by rubber(the thickness is 20-25mm)
2. Shaft: alloy cast iron HT300; Bulkhead: 45# round steel
3. Diameter:500-2000mm
4. Face length: 1000-10000mm
5. The largest line pressure is 300kg/cm.
Advantage:
1.Liner pressure can reach 380KN/m. The surface of the coated area has 21%-23% tapping.
2.The speed is about 1000m/min; special bonding system ensures the safe operation under high speed and high linear pressure.
3.The water entering the blind hole can be thrown out by the compressed air after the pressure is released.
4.Good wear resistance, reduce the wear of the felt.Effective dehydration,stable hardness.
