the risk of an explosion is low. Vertical Spindle Mills The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, and at the fan exit for exhauster systems.
Coal milling Question 2. We are having a 1.5Mt six-stage Precalciner kiln operating with South African coal having a VM of 28 per cent. Now we thinking to switch over to Indonesian coal with high VM content (up to 42 per cent) and Chinese coal (VM up to 32 per cent).

explosions is needed as a basis for the development of techniques and strategies for explosion prevention, suppression, and mitigation. In the coal mining industry, rock dust (usually limestone) is added to the coal dust deposits to act as a heat sink and inhibit flame propagation.
power than coal dust. The generation and accumulation of the combustible dust in grain facilities create explosion -ger to human lives and grain facilities (Fig. 3). Alongside vapor cloud explo-sions, dust explosions pose the most hazard within the process industry, especially within grain elevators, bins, silos, four bins and feed mills. The
The accident occurred about 1 p.m. Saturday in Unit 2 of the company's coal-burning Plant McDonough-Atkinson in Smyrna, about 10 miles northwest of Atlanta. Georgia Power spokeswoman Lisa Frederick said the blast occurred minutes after workers restarted a coal pulverizer. "The pulverizer had been taken off-line for some maintenance work.
The coal mill is operated as an air-swept mill and "blows" directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler. The combustion "cloud" will propagate to where it finds ...

Dust Explosion Prevention A dust cloud of flammable concentration can be produced in industry either by design or by chance. For example, lean-phase pneumatic transfer systems handling flammable dust have an almost continual dust cloud present. In processes such as the filling and emptying of dust containers a dust cloud of flammable concentration is produced transiently.
