Energy consumption for drying of concentrates at concentrators is at least 10-15% of all energy costs of mining enterprises, so it is very important to optimally control this process to minimize energy consumption.

The preparation of a mixture of several material components is included in many technological processes. The problem of minimizing the maximum error of the relative proportion of components arising due to proportioner errors was considered in the work.

In many beneficiation plants, for example, in the beneficiation of iron ores, it is possible to regulate the mass flow rate of cake (load) entering the drying units ....

Let at a distance d from a plane-parallel layer of thickness a with dielectric constant e a spherical conductor of radius g is placed, or a capacitor consisting of two such conductors located at a distance I from each other ...

Previously, the authors proposed a mathematical model of the process of cake drying in a rotating drying drum with longitudinal feeding of the drying agent. On the basis of this model was set and solved by methods of classical calculus of variations the problem of optimal control of the drying unit ...

The drying drum as an object of automatic control was considered earlier. The main control actions in this system are the temperature and velocity of the drying agent, while the load (the flow rate of cake at the inlet) acts as the main disturbance. On the basis of the analytical synthesis performed, an operating model of the automatic control system (ACS) was built, which successfully passed tests and was accepted for implementation on all drying drums of the concentration plant of the Kovdor Mining and Processing Combine.
