Ultrafine coal dewatering is of great importance to the coal industry due to its impacts on the handling and utilization characteristics of coal products. Commercially available filtration techniques are either ineffective or costly for dewatering of ultrafine coal to the desired moisture level of about 20%.

ultrafine coal pelletizing machine has been built and tested to optimize the ultrafine coal dewatering efficiency, and at the same time, fabricate strong and robust coal pellets to meet coal transportation needs. INTRODUCTION AND BACKGROUND In the ultrafine coal cleaning process, small coal particles (-400M x 0) are produced during

It is well known that a large portion of the pyrite particles in the coal seams of the Illinois Basin are finely disseminated within the coal matrix. In order to liberate these micron size pyrite particles, one must use a fine grinding operation. The ultrafine coal particles are difficult to dewater ...

dewatering of ultra-fine coal and to find better methods to employ for this purpose. One should also keep in mind that, even when a plant has a flotation circuit, there is still the need to dispose of the flotation tailings. 2. Dewatering of ultra-fine coal Filtration has been the dewatering method employed for ultra-fine coal for many years.

Abstract Ultrafine coal (−150 μm) can be effectively cleaned using advanced separation techniques such as column flotation, however, dewatering it to below 20 percent moisture level using the conventional dewatering techniques is difficult. A comparative flocculation filtration study was performed for enhancing dewatering of ultrafine coal using vacuum, hyperbaric, and centrifugal filters.

Dewatering process was done by means of a Buchner Vacuum process with a maximum vacuum pressure of 0.8 bar (80 kPa). Coal suspension was poured into a funnel of 110 mm in diameter which was attached to the filtrate flask. Another flask was also put in between the pump and filtrate tank in order to reduce the pump's oscillation effect on the ...
