Fixed and Mobile Sanding Systems

Bertolotti

Sand refilling systems are designed to meet the most restrictive standards in terms of safety and, in particular, the harmonised rules of the new Machine Directive 2006/42/CE. Furthermore, particular attention is given to limiting dust emissions and reducing dust concentration for a healthier working environment.

Customers can choose a standard configuration of the plant or ask for a specific arrangement, depending on requirements. It is possible to have both a fixed sanding system or mobile units for sand refilling.

The fixed plants are essentially composed of a sand storage silo, a propeller and local sand tanks, as well as and one or two dispensing guns. The sanding system is completely automatic, and equipped with a compressor and centralised dust filtering unit. Sand transfer piping can be made from carbon steel or stainless steel depending on the request, and fitted to the roof or inside a trench at floor level.

The mobile unit is independent, equipped with a sand tank (200Lt, 350Lt or 500Lt available capacity), and fitted on an electric vehicle or frame movable with forklift. It features a compressor and dust filtering system on-board. A high-pressure sand transport propeller allows for a flexible pipe length up to 15m and filling height up to 4m.

The main control panel is usually inside the technical room. A clear user interface on a colour touchscreen panel provides all parameters about settings, performances, alarms and diagnostics. For each working section, clients can choose the operating components, and the software will automatically reconfigure the system.
