SBM is really a experienced producer of ore beneficiation machines and rotary kiln tools and we’ve been granted to be the well-known and superb solutions manufacturer. Our Iron Ore Crusher Price tools is sold to locations all over the nation and also other countries and has been well acquired with its superior high quality, most competitive costs and our experienced and favorable services.

Short Introduction: Because of the substantial amount of lean ore (accounting for 97.5% of the total reserves) and complete ore which associated with other parts (accounting for one-third on the complete reserves) in our country, many of the iron ore needs dressing process ahead of smelting. In 1996, the selected iron ore was 214.97 million tons which accounts for 85.2% in the amount of undressed ore manufacturing of 252.28 million tons.

Following, we will give a detailed introduction to its beneficiation technology and gear utilized in this procedure.

1. Rock crushing:

The dressing plants in our nation frequently use this kind of three sections of crushing method as coarse, medium and fine breaking to crush it. For your coarse crushing, 1.2m or one.5m spinning back crusher is applied; 2.one m or two.2 m common cone breaker for medium breaking, and 2.one m or two.two m short-headed sort cone crusher for fine crushing. The ore soon after coarse breaking has beneath 1m of lumpiness, after which by medium and fine grinding, it will likely be screened for completed merchandise with granularity significantly less than 12mm and after that transported towards the grinding slots.

2. Rock grinding:

Almost all of the grinding technologies in our country employs two paragraphs approach and for smaller and medium-sized concentrator, they use one particular stage method.

3. Ore beneficiation technologies:

(1) Magnetite Dressing technology

It is actually largely utilised for dressing magnetite with minimal taste. For the reason that the rocks have a sturdy magnetism and easy to grinding, a lot of the magnetic ore-dressing plants adopt a single stage and many phases course of action for its crushing and grinding. Later on, our country independently researched and developed eternal magnetization technology for that magnetic separator. Following the 1960s, the brand new engineering of fine screening and grinding once more helps make the focus grade increase to about 66% from 62%, therefore realizing the necessity from the Ministry of Metallurgical Industry that the focus grade needs to be enhanced to 65%.

(2) Multi-metal connected ore beneficiation:

This type of rocks have complicated element and diversified forms, in order that the procedures, products and production method are different. One example is, In Panzhihua, plants there gained about 53% ferrovanadium focus by magnetic separation, plus the gangue is disposed via light porcelain scavenging, double beneficiation, flotation and drying electricity assortment and in the long run, titanium and cobalt concentrate are acquired.
