General Director’s message

Dear Sirs,

2021 was a very difficult year for us, as well as for all Ukrainian product manufacturers.

The rise in prices for metals, scrap metal, purchased components, and especially for energy resources, in particular, for gas, the price of which for industrial enterprises increased 6 (six) times over the four months of last year, made its own adjustments.

And, nevertheless, despite the challenges of the real life, we are honest and responsible to our partners; we have always fulfilled and keep fulfilling obligations assumed by us!

Let me assure you that at present the company is operating as usual, continuing to manufacture and to supply products, performing works in a timely manner within the framework of concluded contracts and faces the future with confidence!

Kind regards,
General Director NKMZ PJSC

Hydraulic rock breaker for Ingulets Iron Ore dressing Works (Ingulets GOK)

At the end of 2021, a new tract of the in-pit crushing and conveying technology complex (CPT) was put into operation in the open pit of the Ingulets Iron Ore dressing Works (Metinvest). The complex is designed for coarse crushing and transportation of ore from a depth of minus 300 m to the ore processing plants of the enterprise. As part of this complex, “NKMZ” PJSC has designed, manufactured and delivered the ККД -1500/180 crusher and other equipment.

To improve the safety of work on crushing oversized pieces of rock and increase the productivity of the entire technological chain, the customer decided to equip the new in-pit crushing and conveying complex with a stationary rock breaker.

The rock breaker is executed as manipulator rotating on a turntable, at the free end of which a hydraulic hammer is fixed. Due to a sufficient number of degrees of freedom of the manipulator, the hydraulic hammer splits the oversized rock mass to acceptable dimensions directly in the crusher’s receiving hopper.

In order to reduce the time of commissioning works, the equipment was delivered in a state of increased assembly readiness.

New spreader made by NKMZ was put into operation

For more than a month, a new modern spreader OГС-4000/125, designed and manufactured by Novokramatorsky Mashinostroitelny Zavod (NKMZ) has been successfully operating in the Muruntau open pit mine of the Navoi Mining and Metallurgical Combine (Republic of Uzbekistan). The maintenance service specialists have no complaints about its work.

It is a part of the rock conveying complex, which was also started up in October. This is the first of two spreaders supplied by NKMZ to Navoi MMC last year. Erection of the second one is nearing completion. Its startup is planned for the 10-th of December. The work was carried out under the guidance of Novokramatorsk supervising engineers.

Uzbek miners preferred NKMZ spreaders to machines of world leaders because of their production, which have more than 100 units of these products in their reference lists. They ordered two spreaders at the one time, because these machines are not representatives of the production series, but were designed and manufactured according to the individual technical assignment, taking into account all the features of mining operations at the Muruntau open pit mine. The miners of Navoi MMC completely trust in the Novokramatorsk brand, because the steeply inclined conveyor that has been in operation at this open pit mine since 2011 for the first time at NKMZ has earned their best reviews. The other Novokramatorsk mining equipment, which they are also satisfied with, is in operation at the combine.

The new spreader has the original design and corresponds to modern world analogues. The spreaders were the largest of the machines shipped in 2020 by the division of ore-and-mining and press-forging equipment of NKMZ: weight of one – 1130 tons, length – 140.8 m, height – 42 m, width – 14 m, production capacity – 4000 m3/hour.

In two complexes of cyclical-and-continuous flow technology, in which these spreaders are installed, two-by-two crushing and reloading devices are in operation. Each of them includes crushers also manufactured at NKMZ.

Cooperation between NKMZ and Navoi MMC continues. This year, the Novokramatorsk workers have already sent to Uzbekistan skip and cage-type winders ШПМ МПМН-3,15х4, five mills МШЦ 5500х7500, the mill ММС 90х30. There are prospects for the next year as well.

NKMZ and General Electric: cooperation continues

In November, NKMZ finished the contract for the supply of complete rotor shafts for the Garret oil field project of General Electric. NKMZ specialists have manufactured and supplied three rotors weighing 15 tons each.

NKMZ started working with GE Oil&Gas division of General Electric in 2013. Then the Ukrainian company was certified as a supplier of parts with a full cycle of finishing machining for GE Oil&Gas – a global manufacturer of generators and electric motors for pumping gas and oil. During the period of cooperation, NKMZ has manufactured more than 3 thousand tons of parts for GE Oil&Gas.

Rotor shaft is a crucial part, to which very high requirements are imposed on the accuracy of machining – the total mechanical run-out, reflecting all the geometry errors, should not exceed 9 microns. Manufacture of these products feature a special technique for monitoring the run-out and geometry errors of the bearing journals of the shaft by several sensors and in different planes, which had not been used until that time when testing similar parts. To carry out this type of monitoring, NKMZ purchased sensors, equipment and software from the world’s leading manufacturers – TESA (Switzerland) and Bently Nevada (USA). NKMZ specialists have also developed and manufactured the corresponding equipment.

In addition, before launching rotor shafts into production, NKMZ specialists developed an individual plan of the production process, which was considered and approved by representatives of General Electric. Manufacturing monitoring and final acceptance of these products have been carried out by inspectors from GE Power Conversion and Bureau Veritas.

Continuing further cooperation with General Electric, Novokramatorsky Mashinostroitelny Zavod is currently manufacturing shafts weighing from 7 to 47 tons for this company. Their shipment to the customer is expected in December 2021.

This is the third bucket wheel excavator of this model manufactured by NKMZ for this Kazakh company. Two previous ones, supplied by the NKMZ in 2012, are 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 the creator of reliable and high-quality large bucket wheel complexes weighing up to 6000 tons, manufactured during the Soviet period for work in open pit mines. Some of them are still operated, far beyond the guaranteed service life. For example, a large bucket wheel complex has been operating at the Volnogorsk GMK since 1979. But such complexes have not been purchased by the mining enterprises of the post-Soviet space for several decades.

The bucket wheel excavator for Sokolovsko-Sarbaiskoe gorno-obogatitelnoe proizvodstvennoe obedinenie JSC (SSGP) is a small machine (weight: over 188 tons, length: 35 m, width: 7.5 m, height: 8 m), which is used in closed warehouses for material handling. Its productivity makes 1500 t / h, the height of the material intake is 9.5 m, the depth of the material intake is 0.5 m from the zero mark. Its main advantages when performing these works are mobility and productivity.
