An impact roller is a component designed to absorb the energy generated when heavy or irregularly shaped materials fall onto a conveyor belt, thereby mitigating the impact on the belt.
These rollers are typically mounted on devices known as idlers and installed at points where conveyed materials fall, such as hoppers or chute outlets. By dispersing the impact force, impact rollers help extend the overall lifespan of the conveyor system. Additionally, rubber impact rollers not only cushion the impact but also reduce noise and vibration associated with loading. They are also referred to as impact idlers.
Impact rollers are used to cushion the impact on conveyor belts and prevent damage. They are designed to absorb the shock from falling materials. With their high impact absorption capability, they reduce the risk of damage and abrasion to the conveyor belt, extending its life even under harsh operating conditions. Key installation points for impact rollers include:
Conveyor systems are utilized across various industrial applications to streamline production, packaging, and distribution processes. In the logistics industry, they are used for efficient sorting, loading, and unloading of parcels. In manufacturing, their primary use is for transporting parts, materials, and products.
In the automotive industry, conveyor systems are used on assembly lines to move car bodies between processes, efficiently supplying necessary parts for assembly. In mining, they transport ores from extraction sites to processing facilities, reducing production costs and improving operational efficiency. In food processing plants and packaging lines, conveyor systems are essential for automated transportation and packaging of food items. They are used in processes such as washing, heating, and packaging, contributing to improved production efficiency and hygiene management.
Impact rollers are effectively utilized in these industrial scenarios. For example, in mining, they are used to absorb the impact of handling ores and other heavy materials. In manufacturing, impact rollers are used on assembly lines to smoothly move parts and products. Additionally, impact rollers prevent slipping and smooth out vibrations, ensuring the safe and efficient movement of items during packaging processes. In the transportation sector, impact rollers aid in managing heavy loads, enabling efficient and safe transport. Specifically, they are used in baggage handling systems at airports and shipping facilities.
Impact rollers are manufactured by bonding a rubber coating onto a steel tube roller. This bonded rubber coating prevents surface separation and cushions the impact from falling materials. Impact rollers are attached to parts called idlers and used at necessary points on conveyor systems to mitigate impact.
Some impact rollers are equipped with rubber rings. These rubber rings, made from high-quality, durable rubber, enhance the roller’s impact absorption capabilities. The flexibility and elasticity of the rubber rings allow effective shock absorption even under heavy loads. This prevents damage to the conveyor belt and enhances its durability.
Impact rollers come in various diameters and lengths to match the width of the conveyor belt and the material handling capacity. The required impact roller varies depending on factors such as the type of conveyed materials, conveyor speed, and load capacity. Selecting the appropriate product minimizes belt impact, abrasion, and damage.
Rubber-coated impact rollers cushion transported materials, reduce the impact on the conveyor belt, and minimize operational noise. Some specialized rubber impact rollers include:
Polyurethane impact rollers are known for their durability, wear resistance, and low noise. They offer excellent resistance to abrasion, chemicals, and harsh environmental conditions, making them suitable for demanding applications.
