Order: Repair and grinding of the drying drum supporting ring
Characteristics of the order: The client has demanded us to repair a ”repaired” supporting ring which exhibited a so-called “thousand edge” and the drum in operation exhibited large vibrations and “jumped”. We made a gradual correction of the thousand edges to a smooth surface and modified the drum support structure; after our grinding the drying drum has not exhibited any vibrations both unloaded and loaded and its operation has been set to a smooth run.

Customer: LB Cemix, Kotouč Štramberk production plant
Realization: 08/2018 - 04/2019
Place: Štramberk, Czech republic
Order: Installation of a double-shaft kiln line for lump lime burning and other accessories, the manufacture and installation of machinery for the kiln and a milled coal storage silo
Characteristics of the order: The commencement of the works was delayed due to building works, nevertheless, we succeeded to quicken the scheduled works to the end of 2018. On-site we assembled and welded the main body of the kiln and service platform, a sector staircase tower and bridges to particular levels. After the New Year the assembly of platforms was finished and a super-structure above the kiln was fitted with insulation sound-protection walls. Besides the very kiln, equipment for material feeding was assembled as well, i.e. a skip elevator and a distribution movable container with guide chutes. Discharge tables and a system of sealing valves and unloading vibration conveyors were finished, too. In a blower room we installed 8 blowers and a compressor for actuating air and a hydraulic station. On the blower room roof we installed a process filter made by our company, with technological piping and a stack. A carrying structure for the milled coal silo with a capacity of 350 tons was installed behind the kiln.
Parameters: Weight of the installed equipment 600 tons

Customer: CEMEX Czech Republic s.r.o.
Realization: 02/2019
Place: Prachovice, Czech republic
Order: Replacement of 2 parts of a shell of the largest kiln in the Czech Republic (inner Ø 5.6m) including a supporting ring of 80 t
Characteristics of the order: Installation of two pieces of a kiln shell with an inner diameter of 5.6 m. The first part of the shell was replaced including a supporting ring that was put on the supporting shell and centered according to required tolerances during preassembly. A total weight of the part with the supporting ring was 135 tons. From this reason the largest mobile crane in the Czech Republic with a capacity of 700 tons was used. The project was highly demanding due to a short deadline, only 14 days for the complete replacement. Particular parts of the shell were replaced step by step, the shell with the supporting ring was replaced first. Welding of joints on each of the shells was carried out on both the joints at the same time. Both the parts were replaced successfully, thanks to the perfect centering the total run-out of the kiln was reduced substantially. There was no work safety problem for the whole time of the replacement, all uplifts were carried out without any complications according to pre-specified procedures.

A console part of the structure, standing outside the silos, was welded to plates inserted in a concrete upstand that was also built by MZP company.
Parameters: Amount of assembled tons of a steel structure 33 t, a used mobile crane 220 t

Customer: ANDRITZ Oy, Finland
Realization: 10/2018 - 11/2018
Place: Štětí, Czech Republic
Order: 583 tons of demounted and newly installed technology of a kiln line for lime burning; used mobile cranes – 750 t, 220 t, 100 t
Characteristics of the order: Replacement of three parts of a lime kiln shell and an entire drive of the kiln. The main part of the project was a replacement of 3 parts of a lime kiln shell and an entire drive of the kiln, which was the biggest challenge of the whole project because an extremely short time period was left for this scope of works. All deadlines were met. In spite of the fact that the works were performed under significant time pressure no occupational accident occurred and commencement of the line operation after the shut-down was started according to the planned time schedule. Some of the works were performed in concurrence of building works, which increased demandingness and emphasized the continuous coordination of the entire project. The replacement of the kiln shell parts was so difficult also for the fact that the inlet (c. 8 tons) and discharge (65 tons) parts of the kiln are placed inside buildings and this demanded accurate calculations of crane uplifts.

Customer: Lafarge Cement a.s.
Realization: 01/2018 - 03/2018
Place: Čížkovice, Czech Republic
Order: 281 tons of demounted and newly assembled technology
Characteristics of the order: Reconstruction of the dedusting system of a kiln line and mill facility in Lafarge – Čížkovice cement plant. A condition for the reconstruction was to preserve a sheath of the existing three-chamber electro-filter and to design a new filter as the so-called hybrid filter – i.e. the first chamber remains as an electro-filter and the second and third one is re-built as a hose filter, which ensures enhancement of separability of the filter and improves the quality of the medium outletting to the air. The first chamber of the filter was fully reconstructed as an electro-filter, the second and third chamber was equipped with over 1800 hoses with a length of 9 m made of high-temperature resistant fabric as a following filtration element. Aside from the filter reconstruction we also delivered and installed other auxiliary equipment. Despite of the complicated conditions we succeeded to finish the works, so that the technology could commence the operation in time. All functional tests were successful and the following full operation proves high reliability of the line, maintaining the specified output parameters and a high degree of cleaning of the outletting medium.
