Idler rollers (also known as guide rollers or anti-runoff rollers) are key components in belt conveyor systems. Their primary function is to correct belt misalignment, ensuring stable belt operation and reducing wear and tear and downtime risks. They are widely used in mining, port, power plant, and building materials industries, serving as an important guarantee for efficient and safe conveyor operation.
The top roller is a core supporting component of the belt conveyor, installed below the carrying section of the conveyor belt. It is used to support the weight of the material and the belt, reduce frictional resistance, and ensure the smooth operation of the belt. According to different structures and functions, it can be divided into types such as parallel rollers, trough rollers (35°, 45°), and buffer rollers.
The bottom roller is a supporting component installed in the return section (the unloaded part below the belt) of a belt conveyor. Its main function is to support the weight of the belt and maintain its stable operation, preventing the belt from sagging, running off track, or accumulating material. Based on structure, it can be divided into types such as parallel bottom rollers, V-shaped bottom rollers, and inverted V-shaped rollers.
Buffer idler rollers are crucial components in belt conveyor systems. Their primary function is to mitigate the impact of falling materials, protecting the conveyor belt and frame structure, and extending the service life of the equipment. They are widely used in mining, metallurgy, power, port, and building materials industries, playing a key buffering role, especially in scenarios with high drops, large materials, or high-speed conveying.
Friction idler rollers (also known as "self-aligning friction idler rollers") are automatic belt conveyor alignment devices. Through friction and an automatic adjustment mechanism, they effectively prevent conveyor belt misalignment and ensure stable operation of the conveying system. They are widely used in conveying systems in industries such as mining, ports, power plants, and building materials, especially suitable for long-distance, high-capacity, or high-speed conveying scenarios.
Conical rollers are key components of belt conveyors, mainly used in conveyor turning sections or deviation adjustment areas. Their unique conical structure can automatically correct belt deviation, ensuring stable conveyor operation. They are suitable for bulk material conveying systems in industries such as mining, ports, power plants, and building materials.
Tri-roller stringers are key components in conveyor systems. They consist of three rollers connected in series via bearings and shafts, forming a flexible load-bearing unit. They are mainly used in conveying bulk materials (such as in mines, ports, and building materials) or conveying piece goods, suitable for long-distance, high-load, and complex working condition conveying scenarios.
1. Bearings use Harbin, Wafangdian, and Luoyang brands. 2. Material: high molecular weight polyethylene. 3. When the belt conveyor is operating at full load and speed in sections with non-metallic low-noise rollers, the noise level in resident sensitive areas must meet Class 2 standards (60dB during the day, 50dB at night). The conveyor's operating noise meets acceptance requirements. 4. Non-metallic low-noise rollers must be manufactured and supplied according to the attached drawings or with a superior structure.
