Принадлежит: SIEMENS AG

A drive system for a ball mill includes a motor with a slip-ring rotor. The motor is assigned a family of characteristics relating the torque of the motor to a further characteristic variable. The family of characteristics has at least two different characteristics, and it includes a switching element that switches over the drive system abruptly between the two characteristics when there is a constant value of the characteristic variable. In a method for operating a ball mill with a drive system, a drum of the ball mill is moved out of a state of rest when the first characteristic is activated. In the event of caking in the drum of the ball mill, it the drum is moved until the caking is in an inclined position. Actuation of the switching element brings about switching over to the second characteristic.

An apparatus and continuous process for making milled solid in liquid dispersions comprises several steps: 1) Forming a pre-mill mixture of pre-mix, milling media, and previously milled dispersion. 2) Milling the pre-mill mixture to form a milled mixture of milling media and milled dispersion. 3) Separating a portion of the milled dispersion, which is substantially free of milling media, from the milled mixture. 4) Recycling the un-separated mixture by adding additional pre-mix to form the pre-mill mixture to create a continuous milling process. The pre-mix comprises a liquid and a solid. The process is a continuous process and the milling media is recycled through the milling step. Much of the milled dispersion is also cycled through the milling step several times and only a portion of the milled dispersion, which is substantially free of milling media, is removed as the milled dispersion product.

Active grinding media for processing samples

Номер: US20210025792A1
Автор: Karl Jahn, William Z. Todd
Принадлежит: Omni International Inc

An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles.

It finds application in ore enrichment, production of construction materials, waste processing and other industrial branches. The grinding body comprises a spheroidal cone, whose forming curve is part of a circle or of some other geometrical curve and a vertex, and a base which is part of a sphere or of other three-dimensional figure, obtained by rotation of geometrical curves and an edge between them. In one of the versions the cone and the base are connected by a cylinder. For better producibility of the grinding body, a flat spot with circular or other shape is made on the surface of the base. In another version the flat spots are made on the surface of the cone and on the surface of the cylinder between the base and the cone. In a subsequent version the vertex of the cone is cut flat with its plane perpendicular or inclined towards the axis of the body. In other versions, more or less convex peripheral rings are made between the cone and the base. The cross section of these rings has the shape resembling a circle, a triangle or a rectangle.
