Implemented the new installation, installed new electrical distributors and implemented new control and monitoring system for the entire transport of coal (30 belt conveyors).
The wood pellets factory Vitales
Electrical design. Factory processed wood and wood waste into wood pellets. The system comprises a 315kW cutter for timber, an intermediate storag for wood chips, wood chips grinder, and two pelletizer mill and silos for the storage of wood pellets and packaging line.
Coal unloading station TET
Electrical design, manager responsible for electrical system building, programming and commissioning of the programmable controllers, inspection and measurement of electrical installations. The system consists of five conveyor belts and two hydraulic units to empty railway wagons.
Addition of FeSO4 Lafarge Cement Trbovlje
To minimize side effect of chromium compounds in cement it is necessary to add a small amount of FeSO4 just before delivery from factory. Here I made an electrical design, management of installation, programming and commissioning of the system for adding ferrous sulphate to cement.
Transportation and dosing of alternative fuels Lafarge
Electrical project to conduct a dosing system for tires as an alternative fuel in cement production.
The inclusion of hopper scales coal Lafarge
Electrical design, communications, programming and commissioning of the replacement of scales for dosing coal to de kiln for the production of cement.
Control of electrostatic filter Lafarge
Electrical design, management of work, parameterization and commissioning of a new control of electrostatic precipitator.
Automation of overhead crane at Acroni
Electrical design, management of installation, programming and commissioning. The existing crane was controlled by a crane operator via remote control. Position encoders, wireless communication and the programmable controller were added. The system allows interactive control of a crane. The pick up and disposal of products are controlled by an operator, but the crane automatically take the product from the point of pick up to the point of disposal.
Inspection and measurement of electrical installations
The periodical examinations and measurements of electrical installations, which are required by Slovenian law.
Controlling dust extraction GIRK Kalun
Electro design and control system and commissioning. In the existing system of crushing and transport of raw materials at quarry GIRK Kalun was built dust extraction and transport it in the silo. It was necessary to extend the existing PLC controller and power supply of the new drives as well as additional functionality of the control system WinCC.
Control system for sieving tailings PGM Sežana
Electro design and control system and commissioning. In the existing system crushing and transport of raw materials from manufacturer Bräuer was built a sieve, conveyors, belt weigher. It was necessary to extend the controller and power supply of the new drives as well as additional functionality of the control system WinCC.
Controlling the depot of sand PGM Sežana
Electro design and control system and commissioning. In the existing system of crushing and transport of raw materials from manufacturer Bräuer and mixing system of manufacturer Whöewa was built a depot of the sand of different grain size with five boxes and conveyor system for filling these boxes. It was necessary to extend the controller and power supply of the new drives as well as additional functionality of the control system WinCC.
Communication to the coal handling crane at TET
Electro design, installation and testing of communication between the moving crane and building. The crane is on the rails and travels up to 300m along the coal depot. A radio communication was installed to transfer Modbus between the crane controller and coal transport controller in order to control the transport from the crane operator’s cabin.
