A device for generating milling measurement data at an output includes a support structure. A measurement station is supported by the support structure for measuring an attribute of milled material collected thereon and outputting a measurement of the attribute to the output. A mill is supported by the support structure above the measurement station for, while engaged, performing a continuous milling action on a feed material, and continuously or regularly depositing milled material onto the measurement station wherein the measurement station can measure the milled material without interrupting the milling action

A lead needle and lead slime separator for treating thin lead grid of waste lead-acid storage battery, includes: a barrel body, corrosion-resistant and wear-resistant balls, a feed device, a bracket device, a discharge device and a driver. A feed hole is arranged at one end of the barrel body, a discharge port is arranged at the other end of the barrel body. The feed device is mounted at the feed hole, and the discharge device is mounted at the discharge hole. The bracket device is connected to the barrel body, the driver is connected to the barrel body. The corrosion-resistant and wear-resistant balls are arranged in the barrel body. The separator can make the thin lead grid separation complete, clean and impurity-free. It does not need to be melted at high temperature in the melting furnace.

An open-ended grinding mill (1) includes a drum (2) including a cylindrical shell (3), wherein the longitudinal axis (4) of the drum is arranged in a substantially horizontal position in a use position of the grinding mill (1). The drum (2) includes a first end (5) at the feed end of the shell and a second end (6) at the discharge end of the shell. The grinding mill further includes a bearing (8) supporting the drum at the second end, and a support structure (9) to connect the drum (2) to the bearing (8). The support structure is configured to provide a wall external to the shell, whereby the shell and the support structure provide a double-wall structure separating the bearing from the inside of the drum.

The invention relates to a device for the collection, pre-analytic treatment, transport and grinding of solid samples, comprising a flask (1) having an opening (11) closed by a removable stopper (2), for receiving a solid sample. Said flask contains a pre-analytic medium (4), a plurality of balls (3) consisting of a solid material, and a means for holding the balls in place, that is designed to lose its effect when the flask is mechanically shaken or closed by the stopper, in such a way that, when the flask is mechanically shaken, the impact of the balls causes the grinding of the solid sample and the mixing thereof with the pre-analytic medium.

Provided is a stress distribution element for a mill shell joint, comprising an elongated body having a proximal end and a distal end. The elongated body varies in one dimension from the proximal end to the distal end to distribute stress forces from the proximal end to the distal end. The invention also provides a stress distribution system, a stress distribution assembly, a mill shell section, a mill shell and a method of distributing stress incorporating the stress distribution element.

An agitator ball mill comprising a grinding chamber having a cylindrical wall, and further having a rotatably mounted agitator shaft extending into the grinding chamber and on which at least one agitator element is arranged inside the grinding chamber. The mill further comprises an inlet for supplying to the grinding chamber material to be ground and grinding bodies, an outlet for removal of the ground material, and an induction heater for the material to be ground located in the grinding chamber, the induction heater comprising an inductor and a susceptor. The at least one agitator element comprises a susceptor material which forms the susceptor of the induction heater, wherein the inductor comprises at least one coil which is arranged outside the cylindrical wall of the grinding chamber and encompasses the grinding chamber, and wherein the cylindrical wall of the grinding chamber consists of an electrically and magnetically non-conductive material.
