The roller is an important component of belt conveyor, a large number of species. It accounts for 35% of the total cost of the belt conveyor in a bear more than 70% of the resistance, so the quality of the roller is particularly important. The idler role to support the conveyor belt and the weight of the material. Roller operation must be flexible and reliable. Reduce the conveyor belt with a friction roller, accounted for more than 25% of the total cost of the conveyor belt life plays a critical role. Roller belt conveyor is a smaller part of the structure is not complicated, but the roller manufacturing high-quality is not easy. Basic information is an important component of belt conveyor roller, the large number of species. It accounts for the total cost of a belt conveyor 35, roller bear more than 70% of the resistance, the idlers quality is particularly important. The idler role to support the conveyor belt and the weight of the material. Roller operation must be flexible and reliable. Reduce the conveyor belt with a friction roller, accounted for more than 25% of the total cost of the conveyor belt life plays a critical role. Roller belt conveyor is a smaller part of the structure is not complicated, but the roller manufacturing high-quality is not easy. Determine the the roller quality standards were the following: the roller radial runout; roller flexibility; axial runout. Roller classified material into the rubber roller, ceramic roller, nylon rollers and insulated roller. 2, the main trough idlers, all kinds of parallel idlers, all kinds of self-aligning roller group, various types of buffer roller group. (1) trough roller ordinary roller, forward roller, roller bearing type quick-change hanging roller, the three chain roller, reversible roller, variable groove angle idlers, transition idlers, V-roller; (2) parallel to the roller ordinary roller, the comb roller, forward roller, steel glue roller, spiral roller, etc.; (3) self-aligning roller Universal friction reversible roller, powerful roller, taper roller, spiral roller combination roller, etc.; (4) buffer spring plate type idler roller, roller buffer ring type, strong buffer roller, adjustable elastic roller, hanging roller; nylon rollers nylon rollers: 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. Wing Mato roller production the nylon rollers specification model is complete, can produce diameter, length, special specifications can be customized. The nylon rollers the nylon rollers characteristics: 1, nylon rollers with high wear resistance, low coefficient of friction, easy to wear the belt; 2, with excellent self-lubricating nylon rollers, without oiling in harsh conditions easy to get stuck; 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 The ambient temperature range: -40 ° C to 80 ° C; excellent mechanical properties, light weight, easy installation, no maintenance; nylon rollers voice (3-7DB) smooth operation, long life (metal roller life 3-5 times)
