Slag dryer also named slag drying machine. Slag dryer is developed from rotary drum dryer, which has been the ideal drying machine for the big moisture and high density materials such as slag, limestone, clay, sand, etc.
For example, in the particle briquetting process, if the particles of the raw material are too large, the material must be crushed in the briquetting machine before entering the forming hole, so that the briquetting machine consumes a large amount of power.
Heated surfaces dry (remove moisture), iron (remove wrinkles), and add a fine gloss finish to linen for high quality presentation and feel.
In addition to preparing the material for use as a proppant, drying the sand has the added value of reducing transportation costs.
Sometimes referred to as crushers, hammer mills provide an efficient solution for breaking down oversize granular materials at a high rate of production, without the use of a grinding action. They are particularly robust and adept at processing demanding materials.
The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights and the speed of rotation. However, irrespective of the gas and material temperatures the drying (or residence) time may be critical, as this is governed by the rate of diffusion of water from the core to the surface of the material.
The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Based on the configuration, rotary dryers can be classified as co-current, counter current, direct fired and indirect fired.
When you compare iron and steel with something like aluminum, you can see why it was so important historically. To refine aluminum, you need access to huge quantities of electricity. Furthermore, to shape aluminum, you have to either cast it or extrude it. Iron, however, is much easier to manipulate. The element has been useful to people for thousands of years, while aluminum really didn't exist in any meaningful way until the 20th century.

The cleaned and grouped mixture is sent to magnetic separator.

The new 3.0m x 8.0m Dabmar Bivitec screen is designed to treat gravels with a high sand and moisture content at the required processing rates. The project, which included a magnetic scalping plant, came in under budget and has been delivering the anticipated benefits for the past four months. The screen is running in excess of 95% efficiency notwithstanding the fact that it is operating at 17% above its design throughput. Since the new plant came on stream in November 2011, the mine has been able to increase its processing capacity by 30% although increasing the bottom cut-off and the implementation of continuous operations ("contops") also had a significant impact.
