The classification and characteristics of idlers are as follows: 1. **Classification of Idlers:** - **Conventional Idlers:** These are the most common type used in belt conveyors, designed to support the belt and material load. - **Impact Idlers:** Used in areas where the material is loaded onto the belt, they help absorb the impact and reduce wear on the belt. - **Training Idlers:** These are used to keep the belt aligned and prevent it from drifting off track. - **Return Idlers:** Positioned on the return side of the conveyor, they support the empty belt as it returns to the loading point. - **Special Idlers:** These include various designs for specific applications, such as self-cleaning idlers or those designed for high-speed operations. 2. **Characteristics of Idlers:** - **Material:** Idlers can be made from various materials, including steel, rubber, or plastic, depending on the application and environmental conditions. - **Durability:** High-quality idlers are designed to withstand heavy loads and harsh conditions, ensuring a long service life. - **Maintenance:** Some idlers are designed for easy maintenance, allowing for quick replacement of worn parts. - **Efficiency:** Properly designed idlers contribute to the overall efficiency of the conveyor system by reducing friction and wear on the belt. - **Noise Level:** Certain idler designs can help minimize noise during operation, which is important in many industrial settings.
The role of the roller is to support the weight of the conveyor belt and materials. The operation of the roller must be flexible and reliable. Reducing the friction between the conveyor belt and the roller plays a key role in the lifespan of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small component in the belt conveyor and its structure is not complex, manufacturing high-quality rollers is not an easy task.
1. Rollers are classified by material into rubber rollers, ceramic rollers, nylon rollers, and insulated rollers.
2. The main types include groove rollers, various parallel roller sets, various self-aligning roller sets, and various buffer roller sets.
(1) Groove rollers include ordinary rollers, forward-tilting rollers, quick-change bearing rollers, hanging rollers, three-chain rollers, reversible rollers, variable groove angle rollers, transition rollers, V-shaped rollers, etc.;
(2) Parallel rollers include ordinary rollers, comb rollers, forward-tilting rollers, steel-rubber rollers, spiral rollers, etc.;
(3) Self-aligning rollers include general type, friction reversible rollers, heavy-duty rollers, cone rollers, spiral rollers, combination rollers, etc.;
(4) Buffer rollers include spring plate rollers, buffer ring rollers, heavy-duty buffer rollers, adjustable elasticity rollers, hanging rollers, etc.;
