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 grinding plant, comprising: a first mill (10), arranged to grind a product having a greater grain size, provided with an inlet (11) and an outlet (12); a second mill (20), arranged to grind the product to a smaller grain size, provided with an inlet (21) and an outlet (22); wherein the product in outlet from the first mill (10) is fed to the second mill (20). The plant further comprises a screen (30), interposed between the two mills (10, 20).

Disclosed herein are methods and apparatus for producing nanometer scale particles utilizing an electrosterically stabilized slurry in a media mill. A method for producing nanometer scale particles includes adding to a media mill a feed substrate suspension. The feed substrate suspension includes a liquid carrier medium and feed substrate particles. The method further includes adding to the feed substrate suspension in the media mill an electrosteric dispersant. The electrosteric dispersant includes a polyelectrolyte. Still further, the method includes operating the media mill for a period of time to comminute the feed substrate particles, thereby forming nanometer scale particles having a (D.sub.90) particle size of less than about one micron, and recirculating for further grinding the nanometer scale particles from the media mill.

A method for preparing nanometer MAX phase ceramic powder or slurry having a laminated structure by means of ball milling and regulating the oxygen content of the powder. Micron-sized MAX phase ceramic coarse powder is adopted as a raw material, during ball milling, a gas or a liquid-state gas having a special effect is introduced into a ball milling tank, and by means of multi-dimensional functions and regulation such as ball milling parameters and gas reaction, the nanometer laminated MAX phase ceramic powder or the slurry containing the component is obtained. The surface components and the activated state of the powder are regulated while the particle size adjustment control of the powder is realized.

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.

A method for making a shell plate that is mountable to a shell of a grinding mill for grinding ore, said shell plate includes a shell plate body having a first portion including a fixing surface for fixing the shell plate body to the shell and a second portion including 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 includes polyurethane such that the wear surface is made of polyurethane.

In a method for detaching a frozen charge from an inner wall of a grinding tube of a tube mill, a motor of a drive system is operated in a first mode to rotate the grinding tube for grinding. In a second mode, the motor of the drive system is operated to remove the frozen charge from the inner wall of the grinding tube such that operation of the motor to effect a rotational movement of the grinding tube is repeatedly disturbed by a disturbance signal to cause a repeated disturbance within a variable time interval, with the time interval of the repeated disturbance being shortened.
