Profile Liners

Profile liners from Multotec are engineered to return the angle of impact to as close to 90° as possible – the optimal angle of impact for rubber.This works to maximise the energy absorption effects of the rubber to significantly reduce wear rates to increase liner life.. This optimal angle can often be achieved without having to modify the steelwork of the chute.

Effect of combined ferrous burden composition and ore-coke …

Under different combined ferrous burden compositions, the particle flow velocity at the chute outlet, the flow trajectory, the fall radius, and the burden profile do not change considerably. The distribution of ferrous burden mass in the ore layer is consistent with the combined ferrous burden composition as the mass fraction of lump ore increases.

The iron ore bulk density is about 2.5 times lignite, and is to be taken care accordingly. This means material momentum component creating sticking as well as its component resisting sticking, both will be 2.5 times. If you are handling iron ore (-) 100 mm then solution can be similar to lignite (use appropriate liner to withstand more abrasion).
