Elephant Rubber chute liners protect the structural steel of transfer chutes from the impact and abrasion of falling ore and bulk materials. Soft natural rubber (NR) compound at impact zones absorbs energy elastically —?preventing both liner wear and structural damage. Harder SBR compounds at sliding zones resist abrasive wear from flowing ore.
