The invention discloses a method and a device for detecting load parameters of a lining plate
radial pressure type
ball mill, and belongs to the field of automatic detection in a
beneficiation process. According to the invention, a
radial pressure signal and an original point position
signal borne by a measuring lining plate are obtained through a
force sensor and a
position sensor which are arranged on a
ball mill cylinder, and the signals are transmitted to a detection host through a
wireless transmitter-
receiver. The method comprises the following steps: calculating the
position angle of a measuring lining plate and the
radial pressure of the measuring lining plate according to a position
signal and a radial pressure signal, establishing a radial pressure
dynamic data matrix corresponding to each
position angle, filtering the
dynamic data matrix to obtain a filtered
data matrix, and calculating the radial pressure of the measuring lining plate on the basis of the filtered
data matrix. And calculating the loading capacity, the
filling rate and the steel-to-material ratio of the
ball mill through a related
mathematical model. The loading capacity, the
filling rate and the steel-to-material ratio of the ball mill can be accurately detected on line, and positive effects are achieved on
intelligent control over ore
grinding classification, reduction of
energy consumption and steel consumption and improvement of the ore
grinding efficiency and the product percent of pass.
