Boyun''s vacuum disc filters widely use for dewatering of concentrate and tailing in mine industries of nonferrous metal, precious metal rare metal and minerals, and dehydration of electro slag, leaching slag, slag cement such like gold, silver, copper, iron, aluminum, tin, lead, zinc, nickel, palladium, cobalt, molybdenum, phosphorus, sulfur
Sludge Dewatering Systems Most wastewater treatment processes produce a watery sludge byproduct. Disposing of this sludge can often prove very expensive and for that reason, a sludge dewatering system is a great option for reducing costs. By dehydrating the solid byproduct, the weight and volume of product is reduced, delivering major cost savings.
Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.
2.1.1. Iron salts: Ferric Chlorideand Iron ChloroSulfateare mainly used in conjunction with lime to condition the sludge before a filter press. They allow a better filterability by coagulating the colloids (thus lowering the content of linked water) and by microflocculation of the precipitates (hydroxides).

Blast Furnace Slag. Blast furnace slag (BFS) is a product of iron production, which has been widely investigated and utilized, particularly as a supplementary cementitious material for cement or alkaliactivated material, owing to its high hydraulic property or alkali activation reactivity.
The granulated slag and water is then discharged as a form of slurry via a receiving hopper into a dewatering drum. This is a rotating drum within which the slurry is uniformly distributed along the length of the drum. Axial vanes on the inside of the drum lift the slag and deposit it onto a belt conveyor that removes it from the drum to a
Hardened ductile iron volute with 300 Brinell hardness for twice the abrasion resistance of standard ductile iron. Every KZN Series pump is a top discharge pump: KZN heavy duty slurry pumps are utility pumps and frequently dragged from one site to another.
The KZNRF pumps have proprietary process hardened ductile iron volutes. It is the choice of industries that face the most difficult pumping: Lime slurries, mill scale, coal runoff sumps, wash down sumps, ash transfer, tailings ponds, slag pits, food wastes, silt removal, sand & gravel dewatering
Cast house floor design including water cooled and air cooled troughs, tilting runners, and fume collection system. Bellless top and CRM rotary distributor. Lowprofile hydraulic mud guns and tap hole drills (including soaking bar technique). Pulverized coal injection. Ferrous and nonferrous slag granulation and dewatering (INBA).
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
The invention relates to techniques for dewatering of granulated slag and is intended for use at facilities of metallurgical slag granulation. A device for dewatering of granulated slag, made in the form of a hopper with a perforated bottom and walls, when unloading the hopper is
Spiral dewaterer – optimal for dewatering of slag and mill scales spiral dewaterer consists basically of an open trough with arrangements for collection of the products. The inlet flow is evenly spread out through a feed distributor. Coarse material settles and is continuously removed by means of the transport spiral.
Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components

Molten slag is granulated with water to produce a granulatedslag/water sry that is fed into the bottom of a horizontally extending foraminous drum. This drum has radially inwardly extending vanes and is rotated to lift up the granulated slag and separate it from the water, discharging the slag onto a conveyor belt for storage or further use.
Slag height of conventional iron ore BF approximates to hot metal height, but lateritic nickel ore BF slag is much more than conventional iron ore BF slag. Height of slag in hearth is 5~6 times of liquid ferronickel height. Wide adhesive zone of lateritic nickel ore and large amount of slag
steelmaking practices is a mixture of graphite, desulfurization slag, and iron that is skimmed from the molten iron feed to the basic oxygen furnace. It is estimated that the graphite content of kish discarded by U.S. steel plants is more than sufficient to meet the total U.S. demand for flake graphite. That need
