Iron ore beneficiation begins with the milling of extracted ore in preparation for further operations to recoveriron values. Milling operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high.
For this reason, economics plays a large part in determining the use of crushing equipment and thedegree of crushing and grinding performed to prepare ore for further beneficiation.
Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches. Oversize material is passed through additional secondary crushers and classifiers to achieve the desired particlesize.
Secondary crushing, if necessary and economical, isaccomplished by using standard impact crusher or cone crushers followed by short head cone crushers. Gyratory crushersmay also be used.
In iron ore beneficiation operation, the raw iron ore materials will be first reduced to small particle size. It may require crushing the material tomaximize the production of minus 2mm. According to SBM’s experience in crushing technology, we recommended the installation of acone crusher to reduce the minus 100mm pebblesand a VSI crusher machine to fine crush the cone crusherproduct.
The iron ore crushers with low price are also used in the industrial minerals, mining, recycling and general quarrying industries. A widerange of materials are processed through SBM iron crushers worldwide. SBM experts can customize crushing solution in iron ore beneficiation according to your requirements. Here are some popular iron ore crusher machine types. Please contact us for more information.
According to different final products applications, varioustypes of crusher equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing. Iron ore crusher prices are different according to crusher types and production capacities.
The VSI crusher for iron ore beneficiation uses a unique rock-on-rockcrushing action whereby the feed materialgrinds and impacts against itself, minimizingwear costs and maintenance down-time. Thisis especially important in applications such asiron ore processing where the feed material istypically hard and abrasive and wear costs arepotentially very high.
Jaw crusher is available with stationary, mobile and portable applications. The jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials. This is achieved through several unique features such as higher crushing speed, optimized kinematics, a longer stroke and easy adjustment.
Impact crushers are based upon several decades of experience with the impact method. We offer a complete range of impact crushers for stationary, semi-mobile fully mobile applications in both primary and secondary crushing.
Cone crusher is a stationary crusher. These crushers are hydraulic pressure crushers designed to crush a high ratio for high productivity. Cone crushers are ideal for secondary and fine crushing.
Mobile crushers are loaded on their own crawler tracks or towed by truck horse when transported over longer distances to a new location.
T130X reinforced ultrafine mill is a new facility designed by SBM expert basing on statistical analysis and a large number of suggestions from users.
Magnetic separation machine can be applied for wet dressing of ores with the size less than 3mm.
Vertical Roller Mill are advanced mill equipment adopting top grinding technology applied widely in grinding non-flammable and non-explosive materials.
Mobile impact crusher features heavy duty, fully remote controlled high production, and low maintenance.
