Groove roller Note groove roller for conveying bulk materials, groove angle of 30 °; groove roller conveyor Caution: 1, to prevent the conveyor belt load starts. 2, the conveyor belt deviation occurs, should take timely measures to correct. 3 different types, specifications floors conveyor belt should not be together, the joint best glued. 4, the buffer roller type, structure, size, number of layers should be based on the conditions of use reasonable choice. 5, the speed of the conveyor belt generally should not be greater than 2.5 m / s, large blocks, abrasive materials and unloading device fixed pears should be adopted in low speed. 6, the relationship between the roller conveyor drive roller diameter and the conveyor belt fabric layer, the drive roller, enhance the matching of machine to bend pulley the roller groove angle requirements should be based on the design requirements of the transport aircraft, reasonable selection. Should shun the running direction of the conveyor belt feeding direction, should be adopted to reduce the impact of the whereabouts of the material conveyor chute, reducing the material gap distance; conveyor belt by feeding section, shorten the distance between rollers and buffer roller for the drain material conveyor belt to conform to moderately soft blocking plate, so as not to the backgauge board excellent, scratch conveyor belt surface. 8, the friction roller when in use, if any roller missing, should be added and repaired; roller covered by material, resulting in rotation problems, to prevent leakage of material stuck between the tapered roller tape, pay attention to the conveyor belt activities lubrication of the part, but not the oil belt. 9, to avoid the conveyor belt suffered the rack pillars or bulk materials block, to prevent the misfortune to scratch the tear, bucket elevator conveyor local damage, rayon timely repair, so as not to expand. The nylon rollers Introduction nylon roller: low coefficient of friction, wear-resistant, not easy to damage the belt. Self-lubrication, use, no oiling can operate under harsh environmental conditions, easy to get stuck, there is a better anti-magnetic properties. Corrosion resistance, aging resistance, corrosion resistance to weak acid, weak base and an organic solvent, is not toxic and does not pollute able to withstand repeated shock and vibration. Nylon rollers, light weight, only one-third of the metal parts, easy installation, low maintenance, low noise, smooth operation, energy saving, can improve the life cycle nylon rollers dustproof, waterproof performance is good, more than dust and environment use, not water. Nylon rollers features a nylon rollers with high wear resistance, low coefficient of friction, easy to wear the belt; 2, with excellent self-lubricating nylon rollers, without oiling, easy to get stuck in harsh conditions ; 3, nylon rollers with anti-static, anti-smoldering, anti-aging, anti-corrosion chemical (acids, alkalis and organic solvents); 4, can withstand repeated impact, vibration; nylon rollers use of ambient temperature range of : -40 ° C to 80 ° C; excellent mechanical properties, light weight, easy installation, no maintenance; 7, nylon rollers (3-7DB) low noise smooth operation, long life (metal roller life 3-5 X)
