A. The block mould body
The parts which contacted with steam are made of rigid steel (Type 20G for Boiler) welded
construction. Other parts are made of carbon steel. The inner walls are formed by 0.3mm stainless
steel cuniform plates (The buyer will provide the sample for reference).
B. Insulation
The block mould internal body is insulated by rock wool, thickness from 50 to 100mm. The exterior
of the block mould is covered by galvanized plates.
C. Fill gun
3 units special design 160mm hydraulic driven fill injectors. (If there is enough space, the seller
will install 4 units.)
D. Filling system
Fill silo made of galvanized pipe and nylon,10m3 volume with level controller.
Material outlet block for material discharge connecting with material piping to fill
gun. Material suction blower(15Kw) with insulated cabin.
E. Steaming & Steaming mode setting
Maximum steam operating pressure is 2 bar. In each process steps the steam pressure is regulated
with main steam valve DN300 and individual steam regulating valves on each side. Twice cross heating
technology designed in the program. Steam goes into block mould from 2 big sides and discharges from
4 small sides during first cross heating, and opposite step during second cross heating. Block fusion
quality is monitored by foam pressure switch with measuring sensor.
F. Vacuum system
Condenser tank ca. 5m3 with water spraying and sieving units – individual vacuum tank ca. 15m3. 2
Nash vacuum pumps made in China (15kw for each) used on machine.
G. Block Ejection
While process cycle completely, the front door will be opened. The discharge trolley will be carried
to the ready position. Two hydraulic driven ejectors will eject the EPS block to the position of
the discharge trolley. Afterward the door will be closed for the next cycle start. The discharge
trolley will be transferred to the weighting unit.
H. weight unit
The electronic weighting unit is mounted on the discharge trolley transport rail for quality
assurance and data recording.
I. control cabinet
Operating interface by PLC programming and touch screen.
