Abstract (en)
[origin: EP0745427A1] The grinder has a cylindrical casing containing a number of balls which, when the grinder is rotating at its nominal speed, takes up a position between two generatrices spaced by an angle between a minimal angle alphamin and a maximal angle alphamax. An amount of coal is also included which, when the grinder is rotating at its nominal speed, takes up a position between two generatrices spaced by an angle beta. An electromagnetic wave emitter is disposed inside the grinder and at least one wave receiver is disposed outside the grinder. The receiver is associated with an electronic circuit for determining at least one parameter of the grinder selected from the quantity of balls, the quantity of coal and the wear of the cylinder.
