Then, based on the improved evidence combination method, an improved multi-classifier ensemble modelling is proposed in this paper, which is applied to the soft measurement of ball mill load. Experiments are performed with a laboratory ball mill, and the vibration signals of bearing seats are used as auxiliary variables for the mill load.

Increased mill capacity can be achieved by upgrading an existing classifier or replacing a current one with a high-efficiency classifier, such as the BLVT. Capacity improvements can be expected in the 15% to 17% range. The superior design provides controlled and guided material flow right up to and through the classifier.

A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
