The factory produces arboreal granules, which are used as fuel. Such fuel in form of granules is an environmentally pure product, as is made of such raw materials as wooden sawdust and chips.
Technological equipment of the factory is comprised of 3 groups of machinery:
- the set of technological equipment from "Sprout Matador" company (presses and granules production line);
- the set of technological equipment for raw materials drying from "Maguin Promill" company;
- the set of equipment for storage and transportation.
- An automated system is provided for the purpose of control and supervision of the technological equipment.
The factory's personnel have 2 computerized control workstations at their possession, which operate as mutually replaceable units. They make it possible to supervise and control the technological processes of granulation, as well as raw materials drying and preparing, and finished product discharge, too.
The entire production process, starting from preparation of raw materials and ending with granules discharge to storage area, can be supervised by 2 operators.
The automated control system includes:
- programmable controller PLC1 (it controls the granulation and transportation processes);
- programmable controller PLC2 (it controls the material drying process);
- peripheral equipment: ET200.1…ET200.4, DP/AS, inverter "Danfoss";
- operators' computer workstations PC1, PC2.
For the purpose of remote monitoring and editing operation regimes and programs, the relevant opportunities of the Internet are used via Router device.
