    Abstract: A system for use with a roll bowl type mill for the pulverizing of solid fuels such as coal. The system includes hardware in the form of sensors and other components and software to among other things monitor the operating condition of the mill's moving parts and predict their failure. The system can determine the diameter of the mill's rollers, or the reduction and/or depth of cup wear of each of the rollers, the thickness of the solid fuel in the mill, can by analysis determine the wear of each of the one or more roller bearings in the mill and predict their failure and can estimate the mill availability

    Abstract: A diffuser system for multi-outlet pipe structures of the type found in coal pulverizer classifier skirts and in the piping between such classifiers and combustion chambers in coal-fired power plant delivery systems. A plurality of vertical and horizontal diffuser elements comprising toothed bars and rings are arranged in the “skirt” or plenum just prior to the multiple pipe outlets so as to effectively diffuse both axial and radial components of uneven flow distributions.

    Abstract: A coal mill introduces raw coal between a roller and a ring and pulverizes the raw coal. A reduction gear for a mill is provided in a lower portion of the coal mill. A cooling fan is mounted to an input shaft of the reduction gear for the mill which is connected to a motor. A radiator for cooling a lubricating oil which lubricates within the reduction gear for the mill is arranged in an extending portion of the input shaft. An oil pump and a line filter are provided in a lubricating passage which supplies the lubricating oil to the radiator, and a flexible pipe connects between these elements. Accordingly, the coal mill is cooled by air.

    Abstract: A process for pulverizing coal to ultrafine size of a few microns, comprising conveying the coal through successive pulverizers with an inert gas, separating the ultrafine coal from the inert gas, cooling and recycling the inert gas and producing make-up inert gas by water scrubbing and alkaline or monoethanolamine scrubbing boiler flue gases to remove particulate, carbon dioxide, thereby leaving essentially nitrogen inert gas. Control of the final ultrafine particle size is achieved by regulation of the flow of conveying gas through the final pulverizer. Reject material streams are taken from the pulverizers to improve the quality of the product pulverized coal, which reject streams are burned in a furnace so as to recover their heat value.

    Abstract: A process and apparatus for grinding particulate material to micron or fractional micron size. A high velocity stream of high pressure grinding fluid is passed through a multistage Venturi system into which the material is fed to result in self-attrition of particles by impact. Fluid and entrained material are injected into a mill chamber wherein particles of different sizes are separated and classified. Mill preferably shaped to provide an endless path. Patterns of hydrodynamic flow and vortex motion are produced in the chamber so that a solid particle makes many collisions, these conditions being effected by dispositions of high pressure fluid nozzles, design of solid boundary surfaces and regulation of pressure and temperature of oncoming high velocity fluid. Provision is made for recycling the oversized particles either to the aforementioned multistage Venturi system or to a similar but separate system for regrinding and reintroduction into the chamber.
