Economical Shotcrete Mixer-Pump
The US company, Blastcrete Equipment Company has introduced what it claims to be a more efficient and economical mixer/pump.
The hydraulically powered Blastcrete MX-10 Mixer/Pump is a 3” (76 mm) swing tube-style unit designed for refractory shotcrete and pump cast applications.
Although it is designed for ease of operation, it also has the durability to handle the most demanding refractory installations.
Blastcrete say that is more than sufficient to meet applications in foundries, steel mills and cement plants, as well as a variety of industries including glass, power generation, incineration and petrochemical.
The MX-10 features a 998 kg (2,200 lb), high-torque hydraulic pan mixer, which offers a mix time of 2 minutes or less. Combined with a very high-pressure, 151 bar (2,200 psi), piston pump and the unit is able to consistently deliver 10 t of material per hour and achieves vertical pumping distance of 90 m (300 ft).
In order to prevent material build-up and hardening, as well as possible damage to the unit must be thoroughly cleaned after each use the same as other mixer/pumps. This can be time consuming but on the MX-10 has been designed to make the process quick and simple. The receiving hopper swings out, allowing easy access to its lower area and the swing tube for fast cleaning and maintenance. The entire flat pack can be removed from the frame in just minutes to provide easier access for maintenance. For enhanced cleaning ease, a hydraulic pressure washer is an available option.
A hydraulic agitator ensures the mix stays consistent and blended. The agitator's high intensity mixing action assures that the refractory grains and binders remain in suspension as the material is loaded into the pump. The re-mix hopper with agitator has a capacity of 1,134 kg (2,500 lbs).
A 2 m² the operator platform gives increased space and allows the electrical controls to be ideally positioned to prevent debris and water from making contact with the electrical components.
Lifting eyes are mounted on the platform for easy lifting and transport.
The unit is available with either a John Deere 4045T 74 kW (99- hp) or Deutz BF4M 2012 76 kW (102-= hp) water-cooled diesel engine. It's also available with dual 30 kW (40 hp) electric motors.
The MX-10 is CE Certified, meeting European Union safety standards for equipment operation and backed worldwide by Blastcrete's unmatched customer service and support.
New box-shape jaw for CombiCutter.
Atlas Copco has introduced a new box shaped jaw for the CC 3300 hydraulic CombiCutter allowing the recycling rate to be increased in demolition jobs and the recycling process within the crusher to be simplified.
"With the box-shape jaw we are able to achieve defined sizes of demolished material which are ideal for the crusher plant next in line,“ Wolfgang Hohn, Product Line Manager Silent Demolition Tools with Atlas Copco explains. "We cut the demolished material on three sides in one go to prevent too long pieces of rebar and therefore substantially simplify the separation of the different materials."
The new shape also has a positive effect on the amount of fines and dust produced on the demolition site. "More high-grade material can be recycled and the environment is better protected by the reduced dust emissions" Hohn continues.
The "B" box-type jaw has been designed for the CC 3300 CombiCutter. Apart from this, the "U" type jaw for demolition work in reinforced concrete and the "S" type jaw for cutting steel structures are available.
