"1. Roughing of the lean iron ore after preliminary or secondary grinding to exclude such waste rocks as country rocks, improve the grade and reduce the load on the next procedure. 2. Separation of the raw hematite which has not been fully reduced in the closed circuit calcination for further calcination. 3. Removal of iron in the petuntse in...

Desulfurization gypsum dryer is called as ZDSG intermittent rotary gypsum powder wok machine for short and mainly consists of a steel structure base, a wok, a lifting and guiding device in the wok, a roller ring holding wheel, and a driving mechanism. The wok is installed on the furnace, the wok body is directly contacted with flame to heat the...

The centrifugal concentrator is more effective for processing fine mineral mud, and the particle level recovery is about 90% for fraction of 37 ~ 19μm. Since the sorting of mineral particles in a centrifugal concentrator is aided by the combined effects of centrifugal force and lateral flow membrane, hence the concentration ratio is higher than...

The disk granulator for organic fertilizers is just the organic fertilizer granulator. The fillet of the disk granulator’s disk adopts overall arc structure and the granulation rate can be above 93%. There are three discharge holes on the granulation disk for continuous and non-stop production. In this way, it is possible to materially reduce...

High-efficiency concentrator is widely used in the treatment of slime, wastewater, waste residue in metallurgy, mining, coal, chemical industry, building materials, environmental protection and other departments, which has great importance to improve the utilization rate of return water, the underflow delivery concentration and environmental...

The hammer crusher is used to crush kind of middle hardness and weak abrasive material. The compressive strength of the material should be no exceeding 100 Mpa and its water content should be less than 15%, such as coal, salt, Bai Ya, gypsum, brick and tile, limestone. It is also used to broken the waste fiber structure, strong elasticity and...

It is mainly used for processing and crushing of feldspar, quartz, iron ore and other raw materials. Also it applies to the production, fine crushing and intermediate crushing of grinding materials, refractory, cement, steel, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt concrete and other hard, brittle materials with,...

The surface magnetic field intensity of permanent-magnetic roller separator is far higher than that of common permanent-magnetic separator. It is convenient for operation, management and maintenance. It also displays outstanding performance of energy-saving (mainly electricity) in the practical application of all kinds of concentration plants. The...

The rotary drum dryer is also called as a roller drying equipment or a cylinder dryer, it is also the most common and widest drying equipment in application of the mineral equipment. It is suitable for drying metal and magnetic, heavy, and floating concentrate of non-metallic mine, clay of cement industry, and coal mud of coal mineral industry....
