    摘要： A grinding and shaping method using a vertical grinding mill, comprising: selecting a vertical grinding mill with thread pitch/diameter ratio of a spiral rotor; selecting the grade of a grinding medium and determining the filling factor and adding the grinding medium into a grinding chamber of the vertical grinding mill; sequentially initiating a dust collector, an air blowing device, a driving device and a feeding device, wherein the driving device propels the spiral rotor to rotate, and the air blowing device blows upward from bottom of the grinding chamber; adjusting rotation speed of the spiral rotor of the vertical grinding mill to change cycling speed of the raw material and the grinding medium in the grinding chamber; feeding a raw material into the feeding port at an upper end of the grinding chamber; initiating a discharging device, and discharging the raw material from a discharging port.

    摘要： An invention is provided for creating smoothed, heat-treated glass fragments. The invention includes 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.

    摘要： A rotary milling system includes a body rotatable about its longitudinal axis and pivotable about a pivot axis that is transverse to the longitudinal axis. The system includes an interchangeable discharge grate and a solid cover for attaching to an open end of the body. The discharge grate includes a plurality of holes through which milled product can pass while grinding media is retained. The body is pivotable to a vertical orientation, where the covers can be changed, and to a horizontal orientation where grinding can be performed with the solid cover attached or discharge can be performed with the discharge grate attached. The discharge grate is sealed to a discharge housing during discharge via an annular seal, where the discharge grate and body are rotated relative to the fixed discharge housing. The discharge grate can include a deflector portion that deflects milled product away from the annular seal.

    摘要： A lifting wall arrangement at an end wall of a drum mill, having a plurality of segments which are removably installable on the end wall. Each segment includes an inner wall and an opposing outer wall. At least one lifting blade is arranged on said outer wall, such that the outer wall, the lifting blade and the inner wall define a discharge channel leading to a discharge cone. The inner wall forms a part of a sieving wall in the drum mill. Each segment constitutes an integrated unit adapted to be installed on the end wall. The disclosure also relates to a segment of a lifting wall arrangement and a drum mill comprising a lifting wall arrangement.
