Harex GOLD-2010 is a large concrete block machine that can produce concrete
bricks, hollow and solid blocks, pavers, curbstones, retaining wall blocks and
other construction and civil engineering materies.
The machine consists of two parts: main machine with primary filling box
for base mix, and face mix device with secondary filling box for fine surface
layer. With face mix device, a variety of products with beautiful colored face
layer can be produced.
The machine frame is a sturdy structure made of section steel.
Wear-resistant slide bushings are used in the sliding metal bearings of
the guide pillars that guide the moving of mould and compaction head.
Power locks are used in the linking parts, which reduce wear and make
repair and replacement easier.
Double-sliding metal bearings are mounted on two guide pillars so that
mould and compaction head move smoothly without error.
An encoder system adopted for precise distance control
Filling box moves by means of powerful hydraulic cylinder with
shock-reducing device, and its speed can be adjustable by valve.
Filling box has special guiding device of double structure, on which
filling box is freely suspended. Since the vibration is not transmitted to the
filling box, the wear of the filling box is greatly reduced.
Four main shafts and sliders
Proportional control valve that can control hydraulic speed via control
A lifting device driven hydraulically is installed for raising and
lowering filling box when low-height blocks are produced.
The primary fill box can be detached from and attached to (motor-driven)
main machine for maintenance, and automatic locking device is used (by air
An agitator, moving back and forth up to 200 mm and driven by hydraulic
cylinder, is installed to facilitate the filling of material into mould.
A scraper driven by pneumatic cylinder is installed in the filling box.
An integrated vibration table with four powerful vibration motors (11 kW
each, 44 kW total)
The vibration motor is of servo type. The rpm can be freely adjusted
automatically, and the maximum rpm of 4,500 allows high-frequency vibration.
The centrifugal force of the vibrator can be easily adjustable, the
increase or decrease in amplitude is possible, and the rpm of the vibrator can
be made infinitely variable.
Mould is mounted to the compaction frame by pneumatic air-bag clamping
Stripping synchronization by means of four pillars (compaction part,
Two synchronized gears reduce the dimensional difference on both sides of
Two hydraulic synchronization brakes for compaction part can be installed.
Pressure adjustment valve on the compact part
The maximum centrifugal force of the two compaction head ;vibrators is
1,040 kP in normal frequency.
Mould Fastening System:
Adjustable pneumatic air-bag clamping system allows quick mould change
(about 15 minutes) and maximization of vibration efficiency.
Oil pump and driving part including motor are installed separately, and
oil heater is installed on the hydraulic tank.
Two pressure selection stages are available for cylinder operation.
Necessary piping and valves are included.
Oil tank ventilator, oil temperature indicator, oil level indicator, oil
filter for preventing contamination
Oil cooler is installed on the pipeline through which oil returns to the
tank. A compulsory ventilation fan controlled by temperature sensor is also
installed. A separator oil pump is installed on the oil cooler.
