US 12,465,923 B2 · Method for starting a grinding tube

Abstract

A method for starting a grinding tube with an assigned drive device, wherein during the operation of the grinding tube a grinding mode and a charge release mode can be set such that a particularly reliable monitoring of the state of charge located in the grinding tube is ensured, where the grinding tube is rotated and, at a first rotational angle, a first actual torque is detected, a setpoint torque is calculated for a second, relatively large rotational angle based on the first actual torque, an actually occurring, second actual torque is detected when the second rotational angle is reached, an investigation is performed to determine the difference of the second actual torque from the setpoint torque, and the charge release mode of the grinding tube is set when the second actual torque is within the threshold range, otherwise the grinding tube is operated in the grinding mode.

Dependent claims

A method for starting a grinding tube from a standstill state of the grinding tube, said grinding tube including a drive apparatus, the method comprising:

rotating the grinding tube and, at a first angle of rotation, acquiring a first actual torque;
calculating, based on the acquired first actual torque, a target torque for a second, greater angle of rotation;
acquiring an effective second actual torque when the second angle of rotation is reached;
examining an extent by which the second actual torque deviates from the target torque and comparing the deviation to a predefined threshold range;
setting a charge release mode of the grinding tube when the second actual torque lies within the threshold range;
and
operating the grinding tube in grinding mode when the second actual torque lies outside the threshold range.
