A method and related apparatus for liberating particles with specific dimensions from a moist Municipal Solid Waste Incinerator ash (MSWI ash) material comprising particles with differing dimensions. In an aspect, the method comprises feeding an amount of the material in a particle stream, striking the particle stream with a striking body to impart a sudden change in direction of the particle stream, receiving at least a part of the stricken particle stream on a moving surface, and transporting the received particle stream to an outlet beyond the receiving area where the particle stream is divided in a first fraction rich of particles of a first group of particle dimensions, and at least a second fraction rich of particles of a second group of particle dimensions, which second fraction is substantially depleted of particles of the first group of particle dimensions.

A method for producing electrolytic manganese dioxide with high compact density where electrolytic manganese dioxide pieces are milled in a classifying mill to produce first milled manganese dioxide particles where 30% of the particles are larger than 200 mesh and up to 95% of the particles are smaller than 325 mesh. The first milled manganese dioxide particles are milled a second time to produce manganese dioxide particles having a second particle size distribution. Also, an electrolytic manganese dioxide particle composition, wherein when the particle size distribution of the composition is plotted as a function of base-10 logarithm of the particle size, a first peak is centered at a particle size from 40-100 m and contributes a minimum of 20% of the area under the curve of the overall particle size distribution and a maximum of 45% of the area under the curve of the overall particle size distribution.

A method for preheating a beater mill is provided. The method includes: rotating a beater wheel disposed within the beater mill to facilitate circulation of a gas stream between the beater mill and a furnace fluidly connected to each other via both a pulverized fuel conduit and a flue gas recirculation conduit; generating a burner gas via a burner disposed within the flue gas recirculation conduit such that the burner gas joins and heats the gas stream circulating through the beater mill and the furnace; and adjusting at least one of an air supply and a fuel supply to the burner via a controller based at least in part on one of a temperature of the gas stream at an entrance of the beater mill, a temperature of the gas stream at an exit of the beater mill, and an oxygen level within the beater mill.

A material reducing machine includes a rotary reducing drum that is rotatable about an axis of rotation and defines a reducing boundary that extends at least partially around the axis of rotation. The material reducing machine includes an infeed conveyor for transporting material to a front portion of the rotary reducing drum and defines a conveyor plane. The material reducing machine includes a mill box at least partially surrounding the rotary reducing drum and including a mill box lid mounted generally above the rotary reducing drum. The mill box lid has an inlet edge positioned above a rear portion of the rotary reducing drum and an outlet edge positioned above the front portion of the rotary reducing drum. The mill box includes an infeed opening that is configured to receive material from a feed table and has an upper opening defined by the outlet edge of the mill box lid.

The present disclosure provides an apparatus for shredding a pre-defined amount of waste. The apparatus includes a main frame positioned to provide support to the apparatus. Further, the apparatus includes a rotating core to shred, masticate and grind the pre-defined amount of waste. Furthermore, the apparatus includes a body mechanically linked to the main frame through a linkage plate. Moreover, the apparatus includes a hopper mounted vertically on the body. Further, the apparatus includes a first set of mash double row ball bearings symmetrically positioned near the first distal end of the main shaft. In addition, the apparatus includes a second set of mash double row ball bearings symmetrically positioned near the second distal end of the main shaft.

A grinder for grinding relatively loose materials includes a reducing unit and a screen arrangement. The arcuate screen defines a plurality of tracks of apertures that extend in a cutting direction of the cutters. In some cases, only one respective cutter passes over each track and each cutter passes over only the respective one of the tracks. The width of a cutter may be greater than a width of the apertures of a track. The apertures of the screen arrangement may form chevron patterns. The screens may be clamped to a frame by coupling members extending through notches in the screen.
