Separating equipment for the magnetite iron sand

Separating equipment for the magnetite iron sand

Brief

CTB Wet Drum Separator is newly developed iron ore concentrating equipment under wet conditions. It has been designed by engineers having a wealth of knowledge and data, gained over many years of wet drum applications and experience.

We offer a complete service to mining and mineral industries. Our wide and competitive wet drum separators allow us the freedom to select the correct size and type to meet precisely your process needs in the best technical and cost effective manner.

This kind of magnetic separator can prevent the final product from the secondary contamination because of the washing action adopted in the processing. It is equipped with a respective spray pipe for feed and concentrates, and water amount can be adjusted so as to assure suitable density of the concentrate. It can be equipped with co-current, counter-rotation and counter current tanks, and equipped double drums or three drums according to requirements of customers.

Features

Magnet System

This is the most critical part of any wet drum design, ours reflect many years of experience and development.

Our products adopt squeezed multiple-pole magnetic circuit, which can make magnetic field distributed so stable and reasonable that it can not only save energy, but also separate and purify the feed more efficiently.

The magnetic separation zone is comprised of stationary permanent magnet, with ferrite/cerimac magnet or rare earth magnets(NDFeB).

Drum Construction

The main cover is in stainless steel, as is the replaceable wearing cover----the drum can be covered with wearable rubber. Stainless steel end flanges have inner and outer seals ensuring the cover and flange joints are watertight. Sealed for life proprietory, flange bearings have grease nipples fitted and are protected from the slurry running down the flange .The magnet yoke and drum position can be easily adjusted to optimized mass recovery and process performance. The magnet yoke position can be adjusted I + 20 degree by a lever mounted at the end of the drum shaft. The bottle neck (gap between tank and drum surface) can be adjusted vertically by shims and horizontally by slotted holes, bringing the magnet poles as close as possible to the media and ensuring maximum magnetic field strength.

Applications

used for the first stage rough concentration in the ore dressing plants. Increase recovery and reduce the load of the second-stage grinding by rejecting waste minerals.

used for concentrating next stage, increase concentrate grade and recovery rate;

used for separation of iron sand under wet conditions, reject excess silica ,mud and other low-magnetic minerals, increase the grade efficiently.

used before strong magnetic operation, remove iron magnetic minerals and prevent magnetic block;

used for recovery of iron ore in coal dressing plant.
