The grinding process is a typical complex nonlinear multivariable process with strongly coupling and large time delays. Based on the data-driven modeling theory, the integrated modeling and intelligent control method of grinding process is carried out in the paper, which includes the soft-sensor model of economic and technique indexes, the optimized set-point model utilizing case-based ...

The fine grinding mills are classified often into five major groups: (1) impact mills, (2) ball media mills, (3) air jet mills, (4) roller mills, and (5) shearing attrition mills from the viewpoints of grinding machines. For the purpose of size reduction of solid particles, a number of different types of grinding mills are used in various ...

Stable control of the ball mill grinding process is very important to reduce energy losses, enhance operation efficiency, and recover valuable minerals. In this work, a controller for the ball mill grinding process is designed using a combination of model predictive control (MPC) with the equivalent-input-disturbance (EID) approach.

The article presents the results of laboratory-scale research on the determination of the impact of ball mill parameters and the feed directed to grinding on its effectiveness and comparing it with the efficiency of grinding in a rod mill. The research was carried out for grinding copper ore processed in O/ZWR KGHM PM S.A.

To apply a ball mill to the grinding unit for seafloor mineral processing, grinding experiments were carried out using a small-scale ball mill applicable to high-pressure condition. In the experiments, wet grinding and water-filled grinding of size-classified silica sands were carried out at three rotation rates to compare the grinding ...

The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

In the mining and metallurgical industry, in addition to raw materials, the quantitative volume of technological operations has a significant impact on the cost of the extracted metal. As practice shows, the most energy-intensive process is crushing of rocks, which accounts for 30-50% of all production costs. In this connection, the management of this process is one of the main technical and ...

We discuss a new generic optimal controller structure for raw material blending in the cement industry. We focus on an important phase of the proportioning-burning-grinding operation triplet that essentially determines the cement quality; namely, the composition control of the raw mill system. We begin by describing the application of a generic optimal controller structure to this important ...
