If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Universal Rotary Dryer SPB-UNI Standard – Performance and Versatility
The SPB-UNI Standard Universal Rotary Dryer is the ideal solution for efficient drying of raw materials used in briquetting, pelletizing, and granulation processes.
It ensures a uniform, rapid drying process across a wide range of materials, including:
Straw
Alfalfa
Biogas digestate
Fermented manure
Sawdust
Grains
Sand
Other moisture-rich biomass materials
✔️ Perfect for producing:
✅ Briquettes ✅ Pellets ✅ Granules (including organic fertilizer granules)
Designed for maximum efficiency, the SPB-5, SPB-10, SPB-20, SPB-30, SPB-30+-UNI Standard reduces the moisture content of raw materials, preparing them for optimal downstream processing.
It integrates seamlessly into briquetting, pelletizing, and granulation lines, providing high-capacity and stable performance.

Sawdust: input 50% → output 14%, capacity up to 600 kg/h
Straw: input 24% → output 14%, capacity up to 1,000 kg/h
Fermented manure: input 40–45% → output 14%, capacity up to 600 kg/h
Thermal power (heat generator): 300 kW – 2 MW
Fuel type: biomass – briquettes, straw pellets, sawdust, sunflower husk pellets, wood chips, agro-pellets
Total installed electrical power: 20–75 kW
Power supply: 400V, 3-phase, 24V/230V coils ±5%, 50 Hz
Weight: approx. 5,500 kg
Dimensions & configuration: customizable depending on plant layout and requirements
Technology year: 2025
Operating Principle
Industrial solid-fuel thermal unit with pyrolysis and hot air generator, built from stainless steel and fireclay for high-temperature resistance.
Cyclone separators for sparks and dust, including an electrostatic spark arrestor.
Automated feed hopper (1.6–3 m³) for raw materials such as pellets, sawdust briquettes, or wood chips.
Triple-chamber rotary drum with serpentine design for efficient heat exchange.
Fan and cyclone with rotary discharge valve for material separation.
Control panel with PLC (Siemens/Eaton) for automatic operation based on moisture readings.
Two homogenizing hoppers for wet material, 4.2 m³ each.
Drying Process:
Hot air flows through the three-stage serpentine rotary drum, where the wet material continuously mixes and loses moisture.
The dried material exits through the cyclone’s rotary valve, while humid air is exhausted through the ventilation system.
