Abstract

In modern conditions, one of the most pressing problems in coal preparation is improving the technique and technology of dewatering small-class coal polydisperse suspensions, formed at coal-preparation plants. Within this problem, interrelated problems of reducing the loss of useful components, preventing the negative impact of processing enterprises on the environment, reducing the cost of excavating slurry from outside slurry storages are considered.

The approach to selecting equipment based on agreed optimization criteria of the coal preparation product dewatering process is examined in the paper. Performance indicators of different dewatering equipment: sediment moisture; ash content; solid phase retention efficiency in the sediment; solids content in the liquid separation product, and its ash content; coal preparation effect accompanying dewatering process were analyzed.

The technological parameters of vacuum filters, sedimentation centrifuges, filtering centrifuges, and settling and filtering centrifuges were reviewed. This equipment is used for dewatering anthracite and steam coal. Comparative analysis of the equipment is based on the results of experiments conducted at the coal-preparation plants.
