The MAGQUIP HEMASORT is a high gradient rare earth permanent roll separator for dry processing of coarse-grained lump hematite ores (HEMASORT) and chromite (CHROMSORT) up to 50 mm in particle size.

This Iron Ore separator is easily deployed in applications and environments where high-grade lump and direct shipping ore deposits can be mined and processed dry and in situ without costly communition circuits and at high volumes.

The separator employs a large diameter roll arrangement (300mm diameter) for high capacity feeding of large particles on a short belt conveyor system with integrated vibrating feeder for uniform feed across the 1500 mm roll width.

The HEMASORT can be supplied as single stage separator or alternatively as a two-stage separator with magnetics re-treat, non-magnetics re-treat with optional middling product configurations.

Material is fed from the hopper and vibrating pan feeder at a controlled rate on to the short belt conveyor. The ore travels along the conveyor belt towards the large diameter rare earth magnetic roll, particles are then influenced by competing centrifugal and magnetic forces.

Hematite or any other weakly magnetic iron oxide particles are pinned to the roll and travel around the roll periphery held in by the magnetic force.

Non-magnetic particles not influenced by the magnetic forces are thrown from the belt on their normal trajectory at a position on the roll where the centrifugal force overcomes the magnetic forces.

The magnetic roll consists of a series of rare earth permanent magnet rings sandwiched between carbon steel disks with optimal magnet and pole thickness configuration based on large particle sizes and is driven directly by a shaft mount geared motor which also drives the speed adjustable (VSD) conveyor belt.

The MAGQUIP HEMASORT separator will separate and upgrade dry, coarse weakly magnetic and material such as hematite and chromite.

The HEMASORT / CHROMESORT can handle feed rates of up to 200 tph depending on layer depth and bulk density.

The advantages of the MAGQUIP HEMASORT / CHROMESORT Separator include:
