At the end of October 2021, Ukraine’s Novokramatorsky Mashinostroitelny Zavod (NKMZ) shipped a skip mine winder of model ШПМ ЦШ-5х8 to the Sokolovsky iron ore mine of SSGPO in Kazakhstan, which is part of ERG. This is the fourth mine winder designed, manufactured and shipped to customers this year by the mining and press-forging equipment production division of NKMZ.
The ШПМ ЦШ-5х8 model NKMZ says is one of the most productive mine winders in the world, able to lift 60 t of iron ore from a depth of more than 700 m in one lifting operation. By its type, it belongs to multi-rope machines that lift their vehicles due to the friction forces between the drum lining and the rope. The ШПМ ЦШ-5х8 model is mounted on a tower-type headgear, equipped with two lifting motors of 3,800 kW each, a traction sheave with a diameter of 5 m with eight strands for lifting ropes. Its design also includes eight lined strands with a removable lining made of modern German Becorit material with a high friction coefficient to transmit the required torque. The machine is also fitted with shoe brakes having four spring-loaded drives, which provide reliable braking, ease of setup and maintenance. The mining and press-forging equipment production division is also manufacturing another mine winder of the ШПМ 2Ц-6,4 х 2,4 ТД model for TNC Kazchrome JSC in Kazakhstan whose assembly will begin in December 2021.
For the SSGPO Sarbaisky surface mining operations, NKMZ this year launched production of the ЭР1500 – 9,5/0,5 bucket wheel excavator that was also designed by the mining and press-forging equipment production division of the company. This is the third bucket wheel excavator of this model manufactured by NKMZ for SSGPO. Two previous ones, supplied by NKMZ in 2012, are still being successfully operated. “The miners are completely satisfied with the performance of these excavators and therefore placed their order at NKMZ for the production of the third machine. Taking into account customer’s wishes, the NKMZ team made minor modifications in the design of this machine in order to increase its maintainability and ease of use.”
NKMZ is widely known as a supplier of reliable and high-quality large bucketwheel complexes weighing up to 6000 t, manufactured during the Soviet period for work in open pit mines. Some of them are still operating far beyond the guaranteed service life. For example, a large bucketwheel complex has been operating at Volnogorsk GMK since 1979.
The 1,500 t/h bucketwheel excavator for Sarbaisky is a compact machine (weight >188 t, length 35 m, width 7.5 m, height 8 m), which is used in closed warehouses for material handling. Its main advantages are mobility and productivity.
