The rotary drier is driven by a chain. (chain drive)
A manual lubrication of supporting rollers and rings by oil or fats is required.
Dust, rain, pollution, manual lubrication is time consuming, pollution from dropping lubricant
Costs for new rolls are about € 14.000, -.
According to the width of the rollers 2 sets of dry lubricating blocs HG04515 are mounted on the supporting rollers.
Due to the dry lubricants we reach a maintenance-free, ecological, dry and water resistant lubrication. (up to 2 years!!!)
The rotary drier is driven by rollers. (friction drive)
By force of permanent abrasion the operating life of rollers and the ring is only about 350.000 tons.
There is no wear protection on driving rollers and rings.
Costs for new rollers are about €19.000, -.
According to the width of the rollers 2 sets of wear protective adhesive blocs are mounted on the driving rollers.
By the application of wear protective adhesive blocs the operating life of driving rollers and rings is doubled!!!
Dry lubricating blocs HG04515
The maintenance-free lubrication with a friction coefficient of about 0.05 is ensured by the constant run along of lubricating blocs on the metal surfaces (compare electric carbon brush). A manual lubrication with the disadvantages and expenditure is no longer needed, reduced wear on running surfaces.
Wear protective adhesive blocs 10035
lubricate the metal surfaces with a very hard, solid and dry protection coating of about 0,01 mm. This coating is set to maintain the existing friction (friction coefficient 0.3-0.5) and to protect against wear (driving rollers/ wheels).
According to width 1 set is mounted per roller:
Roller width 120-150mm - set with 2 blocs
Roller width 180-205mm - set with 3 blocs
Roller width 245-280mm - set with 4 blocs
All sets are completely pre-finished, lubricating blocs and mountings with visual consumption display, according to rollers width 2 to 8, frame with quick-change system.
For the application the cutout on the cover of the rollers has to be 20mm bigger than the frame dimension.
Mount angle (50mmx50mm) - welded frame
