Process features of panji coal preparation plant

Abstract

Panji coking coal preparation plant is currently being under construction and located in the more economically developed eastern region of China. It is a super-large mine site coking coal preparation plant with an annual production of 12.0 million metric tons per year (2272.7 metric tons per hour). The raw coal processed by Panji plant is characterized by significantly difficult washability and severe degradation effect. Panji coal preparation plant applies advanced and reliable separation circuit and equipment with China’s independent intellectual property rights such as gravity-fed non-deslimed non-classified three product heavy medium cyclone, fine coal heavy medium cyclone, jet flotation machine, inclined pipe thickener, and etc. This paper introduces major characteristics of Panji coal preparation plant in detail in the following aspects: application of the world’s largest gravity-fed three-product H.M. cyclone; fine coal H.M. cyclone without the preparation & storage system for ultrafine magnetite; application of deslimed rougher flotation-cleaner flotation process; and deeply clarified circulating water.
