Uralmashplant JSC has started shipping crushing and grinding equipment to the Tautejak project in Magadan Oblast, Russia.

Towards the end of the September quarter, the complete set of crushing and grinding equipment to crush and grind the gold ore will be delivered to the project, Uralmashplant, part of the UZTM-KARTEX Group, said. The project has been under construction since 2019.

The equipment for Tautejak Mine LLC consists of 10 equipment units, namely a jaw crusher, two cone crushers, two mills and five screens.

Uralmashplant has already shipped cone crushers to be installed at the secondary and tertiary stages of the crushing plant (KSD-2200Gr-D1M and KMD-2200T1-D1M) to the customer and, towards July 15, it plans to complete the shipment of the jaw crusher SCHDP-900x1200U, rated at 250 t/h, which is intended for coarse crushing of ore.

The rest of equipment (ball mills MSHTS-4000×5500 and screens) will be delivered to the mine in accordance with the contract terms before the end of the September quarter.

“All crushing equipment uses hydraulic discharge opening adjustment mechanisms,” the company said.

According to Vitaly Furin, Uralmashplant Chief Designer of crushing and grinding equipment, the machine design for the mine takes into consideration the climatic factors of the region and the location of equipment on-site.

“When we designed the jaw crusher, we took into consideration that it would be installed outdoors and operate at very low temperatures – as low as -45°C,” Furin said. “Therefore, we selected new, stronger steel grades for the body and main frame of SCHDP-900x1200U. Also, the crusher is equipped with an automatic oil heating system and stronger friction bearings of the main shaft.”

Mills MSHTS-4000х5500, to be installed in the primary and secondary comminution stages, will be equipped with soft starters and up-to-date energy-efficient motors of 2,000 MW each, the company said. The full set of mills will include four high-frequency screens capable of sizing material over 1 mm in diameter.

“These crushing and grinding facilities were designed in strict compliance with the customer’s requirements and are able to achieve all declared parameters in terms of capacity and quality,” Furin said.
