Wear Liners in Iron Ore Pellet Chutes

 · I am in search of good wear liners for chutes handling iron ore, iron ore pellets. We need liners which are easily installable and give a life of six months at least. Our conveyors handle @ 1000 tph. We would like to avoid bolted liners due to the risk of liners getting losetned and falling on the belt. I am told "Hardox liner " is good for such applications.

Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the ...

Effect of Bentonite on the Pelleting Properties of Iron

2017-3-13 · The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.

The pressure resistance of pellets formed by activated calcium bentonite addition is much lower than the pellets formed with Karben Sodium Bentonite. Also, when Activated Calcium Bentonite is used as a binder alone, the wet pellet efficiency is also reduced. Karben Pellet Bentonite is specially prepared for Iron Ore Pelletizing....
