Working principle of the batch type, to expand a fixed mass of raw material in a fixed volume which enables to reach easily desired density
Expansion chamber made of AISI 304 stainless steel, cylindrical shape.
Agitator and accessories made of AISI 304 stainless steel, speed control via drive. With the adjustable speed in different steaming phases, enables processing of different materials.
Discharge door located on the floor of the vessel, to empty the chamber fast.
Fluidized bed dryer, inside floor parts made of AISI 304 stainless steel, where the expanded material going out from the expansion chamber to dry the beads. The unit is equipped with a steam-air heat exchanger inside, which avoid the beads from thermal shock.
Material Transport unit, has a rotary valve system, to send the material to the silos.
Machine has a built-in silo control system, with the rigth hardware you can operate this part. Pre-expanded beads from the pre-expander conveyed to the storage silos for 1st and 2 nd expansion stages
After the pre-expansion, you can select the silo from the display, where you want to send the eapanded material. The operator can select several silos at the same time with a priority.
The system follows the selection after the order finishes the machine stops as well. For 2nd expansion, same selection steps are possible. From all the silos, you can make 2nd expansion process.
This conveying system named silo top distribution and all the operation controlled via pre-expander panel.
High Density processing: The air and steam adjustment can be done automatically, in quantity and temperature during all expansion stages. This unit helps to expand densities over 30 kg/m³ till 50 kg/m³. To be on the safe side, densities over 30 kg/m³ should be expand at lower volumes . To do that the levels sensors must be adjusted correctly.
Volume 1.25 m3 which is approximately 1.100 kg EPS capacity. Equipped with flexible hexagonal feeder.
Alternatively material loading hopper; Capacity 3+1 (Octabin) 1100 kg
This unit is necessary to proces under 12 kg/m³ bulk density. The pre-loading silo is located on the top of the expansion chamber, with electronic scale system to control the proper filling for second expansion. The PLC calculates the necessary amount (kg) of material for second expansion, and expand in a fixed volume. The filling from the silo to the machine is done by a vacuum fan.
Machine is controlled by SIEMENS S7 type PLC. Touch panel size 10.1” full color. With this display the operator can change process parameters, and recipes can be added, changed and saved in the PLC. Also can be transferred to any place.
For checking the pre-expanded bulk density, via a sample material taken from the dryer. After each cycle, mateial taken from the dryer and weighed in fixed volume. The unit measures, and inspects the expansion values. Different measurements can be followed on the display. Production data can be saved or printed on a paper.

Rawmaterial is sucked from container in rawmaterial via vacuum unit mounted on the machine. With scaling unit, materail is dosed to the dosing unit. Rawmaterial in the chamber is steamed as needed and is reached to the requested density.The expanded material is discharged to the bed-dryer by the openning door on the side of chamber.Dried material after expansion is transfered to the storage silos by the transfer pipes.Working Pressure: max. 0,45 barChamber volume:150 ltChamber material stainless steel - dryer stainless steelDosaging - automatically with precision scalesScaling 1000/1(material feeding max 3,5 kg for 150 lt)Steaming and exhaust adjustment with proportional PVD valvesInstalled power : 8,4 kwColor : RAL 5012
Vacuum chamber is located direct under the expansion vessel, accelerates the stabilization time. Drying is done by this unit instead of a fluid bed dryer. This type pre-expanders are used mainly by shape moulding plants. The accuracy of the expander, starts just after 5 cycles of starting of expansion process. Density is controlled by the PLC, adjusting the weight of raw material by each cycle automatically. Density Control Unit is used for checking the density each cycle and regulate the weight. Higher densities upto 100 g/lt is possible to expand with this pre-expander.Chamber Diameter:900 mmChamber Volume:0.6 m3Vacuum vessel:0,6 m3Vacuum pump: 7,5 kWRaw material with suction blower: 5,5 kWRaw material suction vessel stainless steel with ATEX sensorRaw material bunkerSensor ATEX type1 pc.level sensor ATEX typeProduction Capacity:15 kg/m³ -(*)17/24 m³/ hour approx. 200-280 kg/hour20 kg/m³ -(*)25/32 m³/ hour approx. 500-480 kg/hour(*)Mentioned values are avarage capacities, which is reachable with proper quality and the rigth type of the raw materials.For low density production, it is necessary to use the suitable raw material only
