Harex SILVER-660 is a verstile but low-cost concrete block machine for
start-up. It is capable of producing normal concrete bricks, hollow and solid
blocks, segmental retaining wall blocks, and other materials for construction
and civil engineering.
Robust, compact and trouble free
Can be equipped with a face mix device for pavers with colored layer.
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.
Double-sliding metal bearings are mounted on two guide pillars so that
mould and compaction head move smoothly without error.
Filling box moves by means of powerful hydraulic cylinder with
shock-reducing device, and its speed can be adjustable by valve.
Filling box is freely suspended on the special guiding device. Since the
vibration is not transmitted to the filling box, the wear of the filling box
is greatly reduced.
Impeller: A device driven by geared motor to facilitate the filling of
material into mould
Two special vibrators are mounted which are braked by inverters.
15 kW x 2 = 30 kW
Mould is mounted to the compaction frame by means of screw joint.
Adjustable pressure adjustment valve
Oil pump and driving part including motor are installed separately.
Two pressure selection stages are available for cylinder operation.
Includes necessary piping and valves
Oil tank ventilator, oil temperature indicator, oil level indicator, oil
filter for preventing contamination
Oil heater is installed on the hydraulic tank.
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.
