iron ore production line - senya crushers

There are over 10 kinds of iron ore in nature. The iron ore with industrial application mainly consists of magnetite ore, hematite ore and martite; secondly in siderite, limonite, etc. The iron ore is one of the most important raw materials for steel production enterprise. Through crushing, grinding, magnetic separation, flotation separation and re-election, the iron can be selected from the natural iron ore.

According to the kind and characteristic of ore, there are many different processes for iron ore dressing. In general, ore dressing plant may use primary, secondary and tertiary crushing processes for crushing iron ore. Jawcrusheris usually used for primary crushing; cone crusher is used for secondary and tertiary crushing. Through primary crushing, and then by secondary and tertiary crushing, ore will be crushed to the suitable size for feeding ball mill.

Iron ore will be evenly conveyed by vibrating feeder to jaw crusher for primary crushing, the crushed material will be conveyed by belt conveyor to cone crusher for further crushing, material after being crushed will be conveyed to vibrating screen for screening, and material with qualified particle size will be conveyed by belt conveyor to final product pile; material with unqualified particle size will be back from vibrating screen to cone crusher for secondary and tertiary crushing, to achieve a closed circuit. Particle size of final product can be combined and graded according to the requirement of client.

The iron ore dressing and crushing production line has the features of high automation, low operation cost, fine particle size, energy saving and environment protection. Sanme can provide customers with comprehensive process solution and technical support, and also can design non-standard parts according to the actual installation conditions of customer.

fuzzy topsis method to primary crusher selection for golegohar iron mine (iran) | springerlink

Selection of the crusher required a great deal of design regarding to the mine planning. Selection of suitable primary crusher from all of available primary crushers is a multi-criterion decision making (MCDM) problem. The present work explores the use of technique for order performance by similarity to ideal solution (TOPSIS) with fuzzy set theory to select best primary crusher for Golegohar Iron Mine in Iran. Gyratory, double toggle jaw, single toggle jaw, high speed roll crusher, low speed sizer, impact crusher, hammer mill and feeder breaker crushers have been considered as alternatives. Also, the capacity, feed size, product size, rock compressive strength, abrasion index and application of primary crusher for mobile plants were considered as criteria for solution of this MCDM problem. To determine the order of the alternatives, closeness coefficient is defined by calculating the distances to the fuzzy positive ideal solution (FPIS) and fuzzy negative ideal solution (FNIS). Results of our work based on fuzzy TOPSIS method show that the gyratory is the best primary crusher for the studied mine.
