Reception and storage of raw materials
- It is carried out on the territory of the plant.
- The site for receiving raw materials is covered with concrete slabs.
- Own railway branch coming to the site, which can be used to deliver raw materials; there are also driveways for trucks.
- The raw material storage area consists of a storage area and a zone of operational supply of raw materials for processing.
- The transport is unloaded by a wood loader based on a LIEBHERR A 924 B excavator.
- Unloading is carried out either in the storage area or directly in the working area of supplying wood for processing.
- Lumber is received by quantity and quality directly at the site; radiological control is carried out.
Primary grinding area
- The function of the site is to provide the following sites with a continuous, uniform and regulated flow of process wood chips by grinding sawdust waste or using clean wood chips of the required fraction.
- Primary grinding is carried out by chipping complex manufactured by BRUKS (Germany).
- Control is carried out by the operator in automatic mode.
Secondary grinding area
- The grinding section is designed to convert large chips with dimensions of 25x25x10 mm into a fraction suitable for the further drying process.
- After grinding, the material enters the hopper, in which the crushed wood chips are accumulated for further uniform loading of the drying section.
- The grinding process takes place in automatic mode on grinding units manufactured by ANDRITZ (Denmark).
Drying area
- The site is designed for drying wood and bringing it to the optimum moisture level for further technological processes.
- The process of drying raw materials is carried out on ALFA-4000 drying equipment – Italy (S.I.E. S.r.l.) – automatically regulated.
Pelleting station
- There are 2 main processes taking place at the granulation site – grinding of dried wood into fractions with a diameter of 0.5-2.5 mm and direct granulation.
- Pressing wood “flour” into cylindrical granules under pressure of up to 300 atmospheres by the method of pushing raw materials through a matrix.
- Two PM 30 granulators, manufactured by ANDRITZ (Denmark), with a capacity of 3.5 t/h, are used in the granulation process.
Production management (ACS)
- All production processes are managed by the ACS TP system.
- Control over the production process visualized on the monitor is carried out by the operator.
- The control system is built on the basis of SIEMENS S7 controller programming (Holland).
Cooling and packaging department
- The cooling and packaging section is designed for uniform cooling and screening of finished granules.
- Manufacturer – ANDRITZ (Denmark).
- Packaging is carried out in “big-bag” bags of 1000 kg and small packaging of 15 kg.
Reception and storage
- Acceptance of a batch of pellets is carried out by quantity and quality.
- According to the results of acceptance, the high quality pellet is subject to transportation to the warehouse of finished products.
- There are 2 warehouses on the territory of the plant with a total area of 970 m2, which allows to have a stock of products up to 1590 tons throughout the year
