Evaluation of existing systems. Why should you have the fire and explosion safety of your coal grinding system (s) evaluated? Let's be clear about this: Most coal mill system designs are 30 or so years old, when realised. And, the applicable standards and guidelines in large parts don't cover what they should cover.
Milling, filtration and storage In a wide variety of industries, in the cement and steel industry, an explosive dust atmosphere is created during the grinding of coal and similar products. This can lead to explosions and therefore requires the consideration of constructional explosion protection measures in the form of pressure relief devices.
In coal milling for power stations, a 'closedloop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the recirculation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of recirculation loops within a mill system.
