Uralmashplant dispatching crushing and grinding equipment to Tautajak gold project

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.

Customised Uralmashplant electric excavator goes to work at East Mining’s Solntsevsky coal mine

An excavator manufactured by Uralmashplant (Ekaterinburg) and customised by East Mining Co has been put into operation at the Solntsevsky coal mine in Sakhalin, Russia, the miner says.

The EKG-20 excavator is designed to excavate overburden in the mine, according to East Mining, and is paired with 220-ton capacity Belaz dump trucks.

“The special feature of this excavator, as compared with the similar models, is a modified bucket capacity,” the company said, adding that the capacity was increased from standard 20 cu.m to 22 cu.m.

This is the 21st excavator to go into operation at Solntsevsky, but it is the first homemade electric excavator, East Mining said.

The company previously purchased and used electrohydraulic excavators from manufacturers in Japan and Germany, but the serial manufacturing of the EKG-20 started nearly three years ago.

“Not only it is similar in performance with foreign alternatives, but also provides a more cost-effective excavation,” the company said. “The machinery is 95% made of Russian components, equipped with a modern AC drive, information management system, detection system for assemblies and mechanisms, workflow parameters checkout system.”

Igor Kovach, the Director of Solntsevsky coal mine, said: “The excavator is wholly-electric. The use of AC drive considerably decreases machine operation expenses. Moreover, the life cycle of EKG-20 is 20 years, while the lifecycle of electrohydraulic excavators is seven years. All this has a positive impact on the corporate economics: according to our estimates, this excavator, as compared with electrohydraulic machines, allows us to reduce excavation of 1 cu.m of overburden two-to-three times.”

The excavator is 18 m tall, over 30 m wide and weighs around 750 tons (680 t). Today, is it the biggest open-mine machine in Sakhalin.

The assembly of excavation equipment was made at the coal mine by the manufacturing company representatives and local specialists.
