Tashkent, Uzbekistan (UzDaily.com) -- Specialists of the Electrosila plant, commissioned by Tyazhmash JSC, designed and manufactured five synchronous motors intended for ore mills at the Navoi Mining and Metallurgical Combine (Uzbekistan), one of the world leaders in gold and uranium mining.

The equipment is specially designed for the customer, taking into account the special needs in terms of technical parameters. So, motors produced by "Electrosila" withstand direct start from the network at a multiplicity of starting torque exceeding the value of the current GOST. In this case, the electric motor can provide starting without the use of a soft starter, which is usually used in order to reduce the load on the mechanisms of the mill, the electric motor and the electrical network at the first moment of turning the ore grinding mill loaded with rock. This feature increases the reliability of the entire system and allows the line to be started in case of failure of the soft start system.

“The design of our equipment allows it to be used for a long time, confidently and reliably in the difficult conditions of mining and processing and mining and metallurgical plants,” said Ivan Zheleznyak, deputy head of the department for the design of mining, metallurgical, transport and power electrical machines at the Electrosila plant. - In addition, the design of the electric motors takes into account additional customer requirements, including the requirements for specific connection to the electric motor sensors.

Cooperation of the power machine building enterprise with JSC Tyazhmash on the supply of engines began in 2019. The current supply includes five synchronous motors with a capacity of 4000 kW, each weighing 55.5 tonnes.

The shipment will be completed in the first half of 2021.
