The purpose of the magnetic-gravity separator MGS-2. 0
MGS-2.0 is designed for the enrichment of magnetic ferrimagnetic materials of ore processing plants. MGS-2.0 is designed for automatic separation of finely milled magnetite-containing products in an ascending water stream under conditions of a uniform magnetic field.
In MGS-2.0, the principle of magnetic hydrocyclonic separation was applied, which was patented by domestic specialists in the early 60s and improved at present. The separator of MGS-2.0 and SU is made by patented technology, which allows the output to have a magnetite concentrate with a significantly low content of silicon dioxide (sand) up to 1.5%.
The designation MGS-2.0 stands for:
1,000 SB. The product meets all modern requirements of mining and processing enterprises of Russia, has increased reliability. Important elements of the MGS – the separator coil and the shutter coil are made by a single monolithic design in IP68 and can work in high humidity conditions. All other electrical products on the separator are also made in cast insulation and correspond to IP 54.
Energocomplekt JSC is a developer of measuring sensors IM-15M5 and automated control system of MGS. Our company has at its sites a full cycle of assembly of magnetic-gravitational separators.
1 with the following climatic factors: - ambient temperature from +1 to +40 ° C; - height above sea level up to 1000 m; - relative humidity not more than 10% at a temperature of +15 ° C, not more than 80% at 40 ° C; - the environment is non-explosive, not containing conductive dust in concentrations that reduce the level of insulation to unacceptable limits, the maximum dust concentration is not more than 1 mg / m3.
The degree of protection provided by the MGS-2.0 shell, from access to dangerous (current) parts and ingress of external solid objects and from water penetration is not lower than IP 54 according to GOST 14254.
Energocomplekt JSC manufactures magnetic-gravitational separators for enrichment of magnetic ferrimagnetic materials used by ore processing plants.
Composition
In the composition on MGS-2.0 goes the equipment specified in Table 1.
Table 1
The microprocessor control module MGS-2.0 UHL4 is based on the signal processor ST10F168. The signal processor performs the basic control and regulation program, as well as exchanges information and monitors service functions.
Structurally, the MGS equipment is located in the IP54 GOST 14254 execution cabinet with natural cooling. The display organs are located on the door of the cabinet. Management of MGS-2.0 is carried out automatically from the touch panel. During debugging and in emergency mode, the MGS SHU control panel is used.
All measurements, signals and control are duplicated on the touchpad on the operator’s remote. Table 2 lists the main characteristics.

MYU-2.0 provides:
- manual mode;
- automatic mode;
- performance of settings and adjustments of the MGS during the separator operation: on water flow and regulation of field strength;
- remote control;
- the ability to program the control system and sensors
The choice between manual and automatic operating modes is made by the operator. Algorithms of work and laws of regulation are implemented in a software way. From the operator’s remote, it is possible to change the structure and control parameters, monitor the separator parameters, view an archive of 50 events. It is possible to communicate the MGS management system through a serial interface RS485, ModBus RTU or ProfiBus DP with the object's ICSMS for remote monitoring.
SENSORY MANAGEMENT OF IYS-2.0
The touch panel installed at the operator’s control point is a 19-inch computer with an operating system and interface program installed. The control panel can control the operation of up to 16 separators (4 sections).
Below is the entire sequence of interface program screens between the user and MGS-2.0. The menu items in this interface are completely similar to those presented above for the A7 control panel. As mentioned above, the A7 control panel and the operator touchpad A12 are independent sources of information visualization for the user. The operation of MGS is possible with any combination of the presence or presence of the above devices on the system.
On the main screen of the MGS, the values of the measured values from the IM-15M5 sensors (DD1-3) are displayed. Control of parameters and their output can be observed on the monitor screen Fig.3.
Fig.4. Main screen of MGS-2.0
On the main screen of MGS, the parameters of the control panel in the closet of MGS-2.0 are displayed. All four main indicators of MGS are repeated at the top of the panel. Additionally, from the touch panel, when working in automatic mode, you can manually set two parameters that affect the flow of washing water and, thus, the upward flow of water in the separator is regulated, as well as change the magnetic induction of the main separator coil. All other parameters are set before starting.
So, when determining the dependence of the level of magnetite in the separator on the upstream and product intake, you can adjust the shutter operation curve so that maintaining the level of magnetite in the separator will be at a constant level in automatic mode regardless of performance (in a wide range). When working the separator, we can observe the values of the system parameters and the serviceability of the equipment.
In the separator, when working, the water level is maintained, which allows you to limit the overflow and the care of the product in the “tail”.
The change in parameters and their input can be seen on the next screen Fig.4.

In the separator, automatic operation mode is provided by measuring sensors that measure the level of water and magnetite and transmit signals to the control system (CC). For convenience, the values of these sensors are displayed on the touch panel in convenient values for service personnel.
IM-15M5, which is manufactured by Energocomplekt JSC, serves to control the presence of magnetic ferrimagnetic materials in the separator. 3 IM-15M5 sensors are installed in the MGS, which monitor the presence of magnetite and its concentration without contacting the abrasive medium (see Fig. 5).

PRODUCTION OF MGS-2.0
Manufacturing of MGS separators, coil products and magnetite measurement sensors is carried out at the sites of Energocomplekt JSC.
Winding coils for sensors is carried out on a winding machine having a finished design, where you can set the step and height of the layer of the wire being wound, depending on the diameter. The equipment has automatic control and allows you to calculate the necessary parameters when winding.
The company produces MGS, performs supervision installation, adjustment and testing of MGS, warranty and post-warranty maintenance, modernization and repair of MGS in operation, training of service personnel, technical advice on the choice of equipment. Supply of MGS equipment is carried out within 4 months from the date of conclusion of the contract and prepayment.
