The trough roller groove roller Features: 1. Groove roller with anti-corrosion characteristics: acid salt corrode it. 2. The groove roller hardness: wear resistance. 3. The sealing: groove roller sealed at both ends with plastic labyrinth seals, slick oil will not leak to the scroll axis long-term; running groove roller in a sealed state. 4. The groove roller ceramic surface: forming an oxide film, a smooth surface does not adhere to the material in contact with the belt friction coefficient is small, reducing the winch driving force. 5. Groove roller Long life: groove roller steel roller 2-5 times a long time, and can reduce belt wear, belts do not run side to extend the service life of the belt. 6. Low operating costs: that groove roller belt conveyor can reduce costs, reduce maintenance worker. Groove roller widely used in large open-air dust, corrosive environments, such as mines, power plants, steel mills, stones factory, cement plants, coal washing plant, Salt Plant, soda plant, fertilizer plants, terminals and other all shipping options Often groove roller. Scope mine roller: ordinary roller: food, loading transporter groove roller: coal, cement, power, groove-aligning roller: metallurgy. Mining, electricity, cement, chemicals, building materials, steel, transportation equipment drum-type roller: metallurgy, chemical, coal, building materials to roll: field of application of mining gear roll, vertical roll: Scope hanging conveyor roller: for range check of belt conveyor idlers: the applicable field of metallurgy. Mining, electricity, cement, chemicals, building materials, steel roller belt conveyor radial runout runout range prescribed by the state, you can keep the tape machine running smoothly, otherwise it will make the belt conveyor tape resonance beating, causing the material spilled, polluting the environment, the more the benefits of a small amount of runout in the case of belt speed higher. China's national standard of 0.7 mm, 0.5 mm Japanese JIS standards for. Roller flexibility in the running of the belt conveyor belt conveyor idlers flexibility is very important, if the roller poor flexibility, rotary drag coefficient is high, the entire belt conveyor system have pay a higher power, consume more power, and sometimes cause the tape to tear and the motor burned more serious can cause a fire. Therefore, the selection of rotational resistance coefficient (preferably less than 0.020) roller belt conveyor design, selection. Axial movement of the belt conveyor belt conveyor more and more advanced manufacturing technology, the axis traverse or a need to focus on the subject, because China's current tape manufacturing technology, belt conveyor installation techniques and advanced countries of the world there is a large gap, often appear belt run, If idlers large amount of axial movement, it will cause the roller earlier damage. General axial runout control better than 0.5-0.7 mm.
