Title:
METHOD OF ADJUSTING GRAIN SIZE OF FINISHING MATERIAL CARRIED OUT FROM GRINDER AND ITS DEVICE
Document Type and Number:
Japanese Patent JPS54123774
Kind Code:
A
Abstract:
A method of operating a milling installation to regulate the fineness of the milled product, in which the milled product emerges from the output side of a mill, e.g. a ball-type tube mill, and material to be milled is introduced at the opposite side of the mill. According to the invention, the mass output rate dm/dt or m of the product is continuously or discontinuously measured and this measurement is used to control the rate of mass output at the output side of the mill so that the output rate is held substantially constant. The invention is applicable to a through-flow (continuous open-circuit) mill in which a fresh starting material is continuously introduced into the mill and to the circulating system (continuous closed-circuit mill) in which the output of the mill is delivered to a classifier which separates the fine product from a coarse component which is recycled to the mill.
