An apparatus and method for the safe preparation of pulverized coal comprises the steps of mixing coal with an inert gas in a pulverizing mill, separating dry coal dust from an exhaust gas bearing a residue of coal dust in a separator, mixing the exhaust gas with additional inert gas and filtering the coal dust from the gas mixture in a filter.
Thereafter, the liquid is separated from the comminuted particles. If the coal contains undesirable contaminants, they may be extracted by adding a leaching agent to the slurry. It is object of the present invention to provide novel apparatus and method for ultrasonic wet grinding of coal and similar products.
It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.
