01/03/2015  The Vertical Spindle Mill (VSM) is one of the most popularly used grinding devices for pulverised fuel (PF) generation in coal-fired power stations worldwide. According to published figures, coal pulverisation is an energy intensive process. Approximately 0.5–1% of gross power generation from coal fired power stations is consumed in coal grinding, or approximately 40.5–81 billion kWh per ...

Soft-sensor approach for measuring pulverised coal flow

This study presents a methodology to estimate the instantaneous pulverised coal flow rate of the E-type vertical spindle coal mills. Modifications over a six-segment coal mill model have been proposed, and particle swarm optimisation technique with Kalman correction has been used to optimise the unknown parameters of the modified model by using real plant data.

Coal-mill optimisation in coal-fired power stations aids ...

There are two main types of mill in common use: the spindle type and the drum type. A typical spindle mill is shown in Fig. 5. Fig. 5b: Simplified typical spindle mill diagram [3]. The vertical spindle mill crushes coal by feeding it between a grinding roller and either a bowl, table or ring at the bottom. Coal enters via the coal feed and falls into the grinding zone, where it is crushed by ...

Pulverizer - Wikipedia

This type of mill consists of two types of rings separated by a series of large balls, ... Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the ...
