"Uralmashplant" JSC (UZTM forms part of UZTM-KARTEX Group) started shipment of equipment for concentration plant under construction – Tautejak Mine LLC (Magadan Oblast, forms part of concern 'Arbat'). Towards the end of the third quarter UZTM will supply complete set of crushing and grinding equipment to organize a process line for crushing and grinding gold-ore materials.
The crushing and grinding facilities of the gold concentration plant, which is under construction carried out by Tautejak Mine LLC from 2019 at the deposit of the same name, consists of 10 equipment units: jaw crusher, two cone crushers, two mills and five screens.
Uralmashplant already shipped cone crushers to be installed at the second and third stages of crushing plant (KSD-2200Gr-D1M and KMD-2200T1-D1M) to the customer; towards 15 July the enterprise plans to complete shipment of the jaw crusher SCHDP-900x1200U rated at 250 tph, which is intended for coarse crushing of ore. The rest of equipment (ball mills MSHTS-4000x5500 and screens) will be delivered to the mine in compliance with the contract terms before the end of the third quarter. All crushing equipment uses hydraulic discharge opening adjustment mechanisms.
According to Vitaly Furin, chief designer of crushing and grinding equipment, the design of machines for the mine takes into consideration climatic factors of the region, and location of equipment at the production 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. Therefore, we selected new stronger steel grades for the body and main frame of SCHDP-900x1200U. Also, the crusher is equipped with automatic oil-heating system and stronger friction bearings of the main shaft,' said Vitaly Furin.
Mills MSHTS-4000х5500 to be installed at the first and second comminution stages will be equipped with soft starters and up-to-date energy-efficient motors of 2000 MW each. 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,' said Vitaly Furin.
