UHMWPE Impact Bars

Impact bar is used in the loading area of the belt conveyor to replace the traditional cushion rollers. The loading zone of a conveyor is a critical area. The type and size of material as well as height of drop are the main factors causing damage not only to belt but also the rubber rings and bearings of the conventional impact idler rolls. 

The impact bar is a combination of three different layers. The top layer is made of UHMWPE for smooth movement of belt, thanks to its low dynamic co-efficient of friction. The middle layer is of rubber to cushion the impact load while the lower layer is made of aluminum, which acts as a fastening device with the main support frame or cradle. The cradlers are custom built to suit specific applications. The installation of impact bar is made is such a way that the belt is not in touch with the bar when running empty. The belt comes in contact with the bar only when it is running under loaded condition.

Features:

1. Surface contact between impact and belt let stress evenly spread on belt;smooth surface of UHMWPE board makes friction lowest, effectively weaken damage to belt, dramatically reduce daily maintenance coat and increase production rate

2. Effectively eliminate the spillage and scattering of the material caused by uneven stress on the belt

3. Guiding angle on UHMWPE board of impact bar guarantee belt running smoothly

4. Ultra elastic rubber can absorb impact in maximum

5. Each part of impact bar is closely jointed by hot vulcanization

UHMW-PE (ultra high molecular weight polyethylene) is an extremely tough and abrasion resistant thermoplastic that is used for applications that require durability and/or abrasive wear resistance.
    UHMW plate is often used for lining chutes and hoppers in order to protect metal surfaces and promote the flow of solid materials such as sand, wood chips, or coal.

UHMW (aka UHMW-PE) (PE1000) offers a combination of excellent properties – outstanding abrasion resistance, superior impact resistance, non-sticking and self-lubricating properties and excellent mechanical properties, even in cryogenic conditions. UHMW Sheet, Rod, Tube and Profiles reduces noise from impact & vibration. It is a self-lubricating material that is chemical, corrosion, and wear-resistant. UHMW is also available in several filled grades including higher-temperature, ceramic-filled, conductive and ESd versions. 

1.         Extremely tough and durable

2.         Low friction

3.         Excellent abrasion resistance

4.         Good chemical resistance

Conveyor rubber impact bar for belt conveyor loading point is a fusion of three different layers:

      •UHMW  pe cap

      •Cushioning rubber or urethane

Alumimium insert or steel insert.

An impact bar is a special mechanical device that distributes the load of an impact over a wide surface area. The bar is made with a special rectangular design that forces any impacted weight to be distributed of the entire surface area of the bar. These types of bar designs are often used in safety equipment for automobile doors, bumpers, and roll cages. They are also used as weight support for conveyor belts.

 Many cars and trucks include impact bars throughout the passenger compartment. These safety devices enclose the occupants with bars in the doors, bumpers, and roof. The bars make the car safer for collisions and rollover accidents. 

An automobile bumper is typically based on an impact bar design. Bumpers reduce damage to the car and occupants by limiting the explosive effects of a collision. The bar has in internal rectangle cut-out area that is designed to spread the load of impact across the entire beam. This makes it easier to support heavy loads during crashes.

 Impact bars are available in many types of material. The most frequently used are rubber, metal, or hardened urethane. The type of material determines the weight and distributed load the barcan support. An impact bar made from hardened urethane is considered one of the most durable because it is more resistant to wear.

1. Avoids the damage to the belt through the contact between the bar and surface of belt. 

2. The conveyor belt is stressed evenly in the loading area, which will reduce the daily maintenance cost. It effectively eliminates the spillage or scattering of the material caused

by inequality of the stress on the belt.

3. The UHMW polyethylene surface has outstanding sliding properties, to reduce the frictional resistance to the minimum.
