Abstract—The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process based on mass flow balance, a model based control strategy is proposed. The controller adjusts the density of medium used to enhance separation in the DMC …

A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.

Introduction: Coal Washing is a process of enrichment of combustibles in coal by removal of non-combustible impurities utilizing industrial separators mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand & Stones etc. so that we get marketable coal suitable for the target consumers. The Washed …

Main washing plant; • Wash/clean coal, wash coal (power) and rejects storage and wagon loading section. A typical coking coal washing plant has the following sections: • Treatment of (−) 13 mm to (+) 2 mm size fractions by heavy media cyclone. • (−) 2 mm to (+) 0.5/0.15 mm coal in spirals or reflux separators. •

The wash water treatment process. During the raw material washing process, sand and wood particles are separated, but remain in the wash water. The treatment system extracts the particles and cleans the water so that it can be re-used in the system. The ANDRITZ cyclone tank is the first step in this cleaning process.

Plant capacity, improved recovery and maintenance are always key coal preparation strategies. Thus, it is expected to develop an optimum design to maximize …

For fines recovery. In some applications, a Separator™ can be used almost as effectively as a cyclone in regard to performance, but fines recovery is one area in which a cyclone is preferred. A cyclone can operate at a pressure higher than 15 psi. This is important when looking to capture as much material as possible.

Conclusion An optimization model for coal washing dense medium cyclones aiming at reducing energy consumption is presented. The model takes into account both the density of the heavy medium and the medium coal ratio that determine the separation and energy efficiency of the dense medium separation process.
