Dust Agglomeration
No matter how effective a dry dust collection system is – eventually the dust has to be discharged from the system. This generally leads to a materials handling nightmare, or at best a waste of water to slurry the dust so that it can be pumped to slimes dams. Loedige's KM series of Ploughshare® mixers provides an alternative solution. It is now possible to micro-agglomerate the dust into fine prills with particles sizes of around 1 mm. This makes the material dust free, facilitating materials handling by conventional means such as conveyor belts or pneumatic conveyors. The material can now easily be recycled to processes or even dumped to landfill without dusting problems being a concern. The units can also be used to micro-agglomerate furnace feeds, such as flotation concentrates, reducing the loads on bag houses.
The effectiveness of the KM mixers at homogenising materials can provide an added advantage for applications in which the effective dispersal of additives, such as binders or reductants, is critical.
With machines being able to handle a throughput of up to 900m³/h, Loedige is able to provide solutions for most dust handling problems.
