Impactalum is an impact resistant alumina ceramic and rubber composite by Halley & Mellowes Group’s Greenbank Terotech. The alumina is exposed to the material flow and is fully embedded into a specially designed rubber backing. Impactalum is excellent for applications of high impact and extreme wear. The alumina provides a very smooth surface for material flow and actually reduces its resistance to friction with service life.
The rubber backing of Impactalum also helps to reduce noise levels within the plant and is engineered to resist the size and type of impact experienced for each individual project. The rubber is pressed around the alumina combining a process of high pressure heat and a superior bonding agent, which makes removal of the alumina from the rubber, virtually impossible.
Although standard panels are available, individual projects can be engineered. The fastening methods are:
- rubber bond
- studs M20 x 50 long
- captive socket
- plug weld
The applications are:
- raw material feed head chute liners rock boxes
- impact curtains skirt cards
- chute liners bucket liners
The backing plates are made of :
- plain rubber with captive studs
- mild steel
- 3 cr12
- stainless steel
