Aliva-201 shotcrete unit for pressure silos

The Aliva 201 is a compact rotor machine developed for pressure silos, intended for even, reliable and dust-free conveying of material in dry-mix spraying. The unit is mounted directly on the silo's slide valve and is quickly installed under the silo using a forklift. Material flows from the silo in a controlled manner and is regulated by remote control, so there is no manual feeding and one operator can handle the entire spraying process. In environments with strict dust requirements, such as urban areas and tunnel projects, the dust-free conveying helps meet health requirements.

The machine conveys dry shotcrete, refractory materials and other dry mixes with a maximum aggregate size of 16 mm, and has a theoretical output of 2.0–5.0 m³/h that is infinitely adjustable. It is electrically driven. With pipes, the material can be conveyed 300 m horizontally and 100 m vertically. The standard equipment includes an air service unit with filter, water separator and pressure regulator, a control cabinet with display, automatic control of silo and conveying air, pressure gauges for system, silo and conveying air pressure, and connections for level sensors, silo valve and vibrator. An integrated horn signals “full”.

The Aliva 201 is built with a solid frame for easy transport and quick installation, and is made from low-wear, long-life materials, which according to the manufacturer reduces maintenance costs. Cable or radio remote control with output adjustment is offered as additional equipment, as is an air hose for the silo's air supply. Applications include tunnelling, concrete repair, skateparks and playgrounds, landscaping and pool construction, construction, and rock and slope stabilisation.
