Our Production System

The first carbon coated mineral production plant in Australia is located and operated in Tamworth NSW, Australia on a 124-acre of mixed crop and beef farm. The plant consists of

  • The continuous reactor that can run either as a combustion unit to just provide heat for drying, a pyrolizer to just produce biochar or CCM. This unit was designed by Professor Stephen Joseph and his son Ben Joseph and manufactured in China.

  • Drying system (material feeding, triple-pass rotary drum dryer, cyclone, induced draft fan, dried material discharging, etc.)

  • Wet scrubber for emission control

  • Thermal oil heat exchanger to utilise the waste heat for drying feedstock or for sterilising / torrefying sludges or animal manure mixed with biochar or CCM

  • The plant has a PLC control system and can be run with minimal supervision.

The plant makes carbon coated mineral organic or inorganic fertilisers. It can also make biochar as well as heat. Depending on what product is required, the average production output is approximately 1 tonne per hour. Usual ratio into the plant is 65-75% wood and 25-35% minerals. The machinery can be scaled up to produce 2 to 3 tonnes per hour. It can run any feedstock with a particle size of less than 15mm and can also make biochar by not adding the minerals.  Moisture content into the reactor has to be less than 20%.

The unit has a scrubber and has very efficient combustion to control the emissions to meet local EPA regulations.

The optional specialized separation and condensation unit can also be added if wood vinegar is desired.

The plant also produces dry wood shavings for animal bedding at about one tonne per hour. This is a separate income stream.

The Drying System

Triple pass rotary drum dryer

The device is a horizontal triple-pass rotary drum dryer with a compact structure and layout. The improved heat exchange between the biomass material and the hot air, enable the more efficient use of heat energy and makes the drying process more cost effective. It has a benefit of lower dust emission. The drying system includes:

  • Triple pass rotary drum dryer

  • Gas or diesel burner & boiler (if required)

  • Material feeding & discharging devices (auger & silo)

  • Cyclone & Induced draft fan

  • Control system

Hollow paddle machine

Hollow paddle machine is used for indirect heating or cooling of paste, granular and powder materials. It can complete operations such as drying, cooling, heating and sterilization.

In the rotor motion, a pair of hollow low-speed rotating shafts is fitted inside the shell. The specific heat transfer coefficient on the shaft is higher than that of any other conduction of drying method. The heat transferring surface also has self-cleaning function. In the drying process the material is turned, mixed, squeezed and relaxed in strengthening the drying effect. The processing time of the material can be adjusted from several minutes to several hours by adjusting the variable feeding speed.

The material inside the machine is in the piston movement, the hollow paddles have a certain axial angle on the shaft, so the material can be dried continuously. The heating medium can be steam, heat conducting oil, hot water, molten salt and so on.

Hammering & pelletizing system

Biomass hammer mill is an efficient machine, designed to meet the particle size-reduction tasks. They’re capable of hammering biomass materials such as wood chips, treebarks, agriculture crop straws / stalks to the desired particle size for further production / process needs, such as making wood or straw pellets.

Biomass pelleting mill is a type of mill or machine to produce pellets from hammered wood chips or crop straw materials. After the loose biomass materials are desified to pellets, it is easier to store and transport. The pelletized biomass and minerals mix is also easier to go through pyrolysis process,to produce more consistent carbon coated mineral products.

Packaging equipment

Semi auto weighing and packaging machine handles 10kg~50kg bags, for which the feeding, weighing, conveying and sealing processes are controlled by a control system. Depending on the size of the bag, per hour handling capacity is between 100 to 200 bags.

Jumbo bag weighing machine handles large size of the bags, ranging from 1~2 tonnes. Handling capacity up to 40 bags / hour, the feeding speed can be adjusted.
