IMPACT ROLLER
for belt conveyors
A complete range of impact rollers for all sectors
The impact roller is a key component of a belt conveyor, as it absorbs the movement of materials on the belt. The impact roller is installed at the material infeed and outfeed points to reduce impact on the belt and improve its service life. This type of handling roller is widely used in the metallurgy, mining, port, chemical, electrical, cement, coal and steel industries. The ROLLDRUM conveyor belt impact roller is adapted to meet the requirements of every application: sealing, extreme climatic conditions, heavy loads, high speed.
The impact rollers are made up of steel rollers of classic design, which are fitted with absorbent rings designed to withstand the pressure caused by the impact of materials on the belt. These support rollers are positioned under the belt’s support strand, at the loading point where the product falls.

Impact roller function
Used as secondary support, impact rollers are positioned according to load points, where pieces of material falling onto the belt can damage the conveyor belt. To limit the impact of the material on the transport rollers, these are covered with a series of rubber rings of appropriate thickness and strength. The impact rollers are subjected not only to the load of the material, but also to dynamic forces as the load falls onto the belt.
ROLLDRUM impact rollers are fitted with steel tubes from 3 to 6.3 mm thick. The impact roller is rubberized from Ø108 to ø245 with a hardness of 65 Sh, pressed and fixed onto the steel tube casing. The faces are welded to the flat roller shell. Depending on the model, the impact roller is fitted with 6204 C3 to 6310 C3 bearings.
The advantages of the impact roller :
Impact rollers offer several advantages:
– Resistance: The materials used for the impact rollers are optimized for strength and resistance. They are resistant to wear, impact and weather conditions. This sturdiness guarantees a longer service life.
– Safety: Shock absorption is not just a question of noise. Impact rollers protect the belt itself and the conveyed material. This protection avoids all possible risks. As shocks and vibrations are minimized, there is less risk of damage to the material being transported, ensuring better end-product quality and less waste.
– Cost-efficiency: This strength advantage not only optimizes production by reducing maintenance downtime, but also lowers long-term costs.
– Low-maintenance: rollers are lubricated for life, and the sealing system is designed to operate in dusty, damp environments.
