Impact rollers
Impact rollers are manufactured as a steel shell with surrounding rubber discs. Impact idler frames and rollers are used at conveyor loading and transfer points for added protection from lump material dropped from height during the transfer process, which can cause damage to the belt.
Main features:
1. Solid design, most suitable for heavy lifting.
2. The bearing housing and steel tube are assembled and welded with a concentric automatic,welding machine.
3. Cutting of the steel tube and bearing is performed with the use of a digital auto device/ machina/equipment.
4. The bearing end is constructed to ensure that the roller shaft and bearing can be firmly connected.
5. Fabrication of the roller is effected by an auto device and 100% tested for its concentricity.
6. Roller and supporting components/materials are manufactured to DIN/AFNOR/FEM/ASTM/CEMA standard.
7. The casing is manufactured with highly composite, anti corrosive alloy.
8. The roller is lubricated and free from maintenance.
9. Working life expectancy is up to 30,000 hours or more, depending on usage.
10. Vacuum sealed with: inner-seal, 3 slot labyrinth seal, V shape rubber ring and eccentrically autocleaning body which has withstood anti water, salt, snuff, sandstone and dust proof experiments.
raw materials and specifications
lt contains threelayers of dust proof structure each fabricated with long lasting rubber seals which can effectively prevent penetration by dust and water.lt generates a high volume,high speed,conveyor belt system resulting.In the design of multiple components.
Welded quality
Roller and bearing housing are welded using an advance,automatic, circular welding machine. The welding process can effectively prevent dust and water from entering the spaces /gap between roller and bearing housing.Also,the smooth surface left by the weld can minimize belt damage.
Bearing and Bearing Housing
All rollers use high quality ball bearings with deep grooves.The bearing housing is shaped through various stages of precision stamping(pressing,forging),to efficiently connect to the bearing cover part.lt needs only to be assembled once,with the various sealed components,which increases the effectiveness of the seal whilst,at the sametime,decreasing the(spinning)impediments to theroller.(enhancing concentricity)
Dynamic Balancing
Our automatic manufacturing and assembling technique has succeeded in accurately balancing the unit to reduce all deviation,therefore both minimizing impact whilst the bearing works at high speed, consequently extending its life span.
Seal
Bearings of the roller are protected by internal and external sealing systems.These help to prevent the deterioration of the lubricating oil and protect the bearings from external dirt infiltration.
The sealing system fabrication incorporates:
* An anti corrosive,protecting shield firmly covering the roller to prevent the penetration from impurities.
* A rubber sealed cover which protects the lip line and prevents penetration by external liquids.
* A steel cover with shell as a guard to protect the bearing from external infiltration.
* A labyrinth seal with lubricating oil as the final stage of protection of the bearing even from dust molecules which may have by-passed the preceding levels of protection.
Examining and Testing
All rollers are subiect to extensive quality control testing and has gone through appropriate standards compliance.
Free from Maintenance
The labyrinth type of inner sealing is manufactured as a lubrication-free device avoiding the need for costly maintenance.
Typical applicatios:
Mining---coal, iron ore,gold,Coal process plants,Coal fired power stations,Import/export terminals,Steel plants,Fertilizer plants,Cement plants,Gravel plants,Quarry.
