What is a dynamic classifier? A classifier separates coarse from fine coal by allowing the fine coal to pass and rejecting the coarse particles for regrinding. A dynamic classifier has an inner...

Airlocks are closed rooms having two or more doors between two different controlled areas having different cleanliness levels as class B and class C, class C and class D areas. These airlocks prevent the direct airflow between these areas during the entry of material or personnel.

Integrated in the mill. Since 1996 Loesche has been using dynamic classifiers of the LSKS series (LOESCHE bar cage classifier) in virtually all mills. The LSKS classifier has proven itself as an excellent separation machine with a high selectivity for mill product. With the aim of increasing the energy saving, productivity and availability of ...

With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of <100 mesh and 95% <200 mesh, or better.

Like mill tailings, coarse coal refuse is a siliceous material, but it has considerably more alumina than tailings. Coarse coal refuse is almost always acidic. Because of its low pH and presence of pyritic sulfur, there are several concerns related to the chemical composition of coarse coal refuse, including the following:

Coal processing, mainly for reducing ash and sulfur contents in the mined raw coal, requires a subset of processing technologies. Some problems in coal processing arise from the way the sulfur and ash are bonded and the need to keep the water content in the cleaned coal low.

In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.

With adequate mill grinding capacity, the MPS mill equipped with SLK static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while the SLS dynamic classifier produces coal fineness levels of <100 mesh and 95% <200 mesh, or better.

A cyclone, also known as a hydrocyclone, is a centrifugal device with no moving parts. It can be used to concentrate slurries, classify solids in liquid suspensions, de-grit liquids, and for washing or cleaning solids. A hydrocyclone can perform ultra-fine separations and handle large-volume feed streams with high solids loading.

There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly …
