A horizontal bead mill for dispersing secondary battery materials and a method for dispersing conductive materials using the horizontal bead mill for dispersing the secondary battery materials are provided. The horizontal bead mill includes a vessel including an inlet and an outlet configured to receive disperse media. The vessel is filled with beads. A rotor is rotated in the vessel to rotate the beads to disperse the disperse media. A driving unit rotates the rotor. An inner surface of a sidewall of the vessel is inclined at a predetermined angle for an axis of the rotor in a manner that an inner diameter of the vessel gradually decreases from an inlet side to an outlet side.

A continuous mill, comprising: a casing (1) having a substantially cylindrical shape and rotating about an axis of rotation (X); an inlet opening (2), concentric to the axis of rotation (X); an inlet duct (20), connected to the inlet opening (2); an outlet opening (3), concentric to the axis of rotation (X); an outlet duct (30), connected to the discharge opening (3); a bend (11), arranged along the outlet duct (30), which defines a curve of the outlet duct (30); a regulator (12) associated with the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least the height thereof; a first aeration duct (21), connected to the inlet duct (20), and a second aeration duct (31), connected to the outlet duct (30), wherein the first and second aeration ducts (21, 31) are open to the atmosphere.

The present invention discloses a method and corresponding apparatus for separating lightweight materials from fabric pieces. The method comprises the steps of (a) introducing fabric pieces into a tumbling means having perforations for lightweight materials in the fabric pieces to be removed therethrough and coupled to a first source of negative pressure; (b) tumbling the fabric pieces in the tumbling means and simultaneously applying negative pressure from the first source of negative pressure to the tumbling means for removing lightweight particles detached from the tumbling fabric pieces from the tumbling means; (c) transporting the fabric pieces from the tumbling means to a top of a vertical separation chamber; and (d) applying forced air to the fabric pieces as the fabric pieces drop from the top to bottom of the vertical separation chamber by gravity for separating the lightweight materials from the fabric pieces, and simultaneously applying negative pressure from a second source of negative pressure to the vertical separation chamber to remove the lightweight materials separated from the fabric pieces from the vertical separation chamber; repeating this step until the fabric pieces are substantially cleared of any lightweight materials. The apparatus comprises a tumbling means and a vertical separation chamber.

Smooth, heat-treated glass fragments are created by placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000° Fahrenheit and rapidly cooled to a temperature below 800° Fahrenheit. The plurality of glass fragments is then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that have a slightly rounded, bead like-shape and are suitable for direct handling without hand protection. The glass fragments as are able to be provide radiant heat in the temperature range of 400° to 800° Fahrenheit. This temperature range and the use of the heat-treated glass fragments provides for a clean burning fire that virtually eliminates any soot and carbon monoxide while burning.

The invention relates to a shell plate, to method for making a shell plate and to a grinding mill for ore grinding. The shell plate is mountable to a shell of a grinding mill for grinding ore, said shell plate comprises a shell plate body having a first portion comprising a fixing surface for fixing the shell plate body to the shell and a second portion comprising a wear surface facing toward interior of the grinding mill, said first portion and said second portion forming a continuous shell plate body, the second portion comprises polyurethane such that the wear surface is made of polyurethane.

A flue gas desulfurization unit is converted from operating with lime or magnesium enhanced lime under inhibited oxidation into a unit that operates using limestone under inhibited oxidation conditions. A ball mill grinding unit may be installed to crush the limestone thereby producing a suspended slurry of fine limestone particles which is pumped to the reaction vessel. When installed, the ball mill may be installed in the process immediately downstream of the existing slaking equipment. The suspended solution may be maintained at a pH in the range of 3.0 to 6.5, optimally at approximately 5.0 to increase the dissolution rate of the limestone reagent produced by the ball mill. The post-conversion process may also require the addition of organic acids and oxidation inhibitors to achieve better SO.sub.2 removal from the flue gas.

A split pulp chamber insert assembly formed for installation in a pulp chamber on a discharge end wall in a grinding mill rotatable about an axis thereof. The split pulp chamber insert assembly include two or more insert elements, configured to cooperate to form a lining covering one or more portions of pulp chamber surfaces that partially define the pulp chamber in which the insert elements are positioned. The split pulp chamber assembly also includes a number of fasteners, for securing the insert elements in predetermined positions in the pulp chamber relative to each other to form the lining that covers the one or more portions of the pulp chamber surfaces.
