Feature

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, retaining wall blocks, and other materials for construction civil and civil engineering.

• Robust, compact and trouble free
• Highly cost-effective
• Can be equipped with a face mix device for pavers with colored layer.

Structure

• 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 System

• 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

Block Machine

• Two special vibrators are mounted which are braked by inverters
• 7.5 kW x 2 = 15 kW

Compaction

• Mould is mounted to the compaction frame by means of screw joint.
• Adjustable pressure adjustment valve

Hydraulic Device

• Oil pump and driving part including motor are installed separately.
• Pilot valve
• 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.
