Silo & Bin Blockages Removed Fast, Safe and Efficiently

The Primasonics® Prima Whip™ offers a safe and fast solution to maintaining clean and continuous operating conditions in silos, bins and hoppers in the bulk solids handling and processing systems. With this system there is no need for operators to enter the potentially dangerous confines of bulk storage systems thus eliminating accidents.

The Prima Whip™ is designed for use remotely through a manhole opening at the top. Powered by compressed air, the Primasonics® Prima Whip™ motor can be manouvered by one operator who manipulates the cleaning head by simple controls.

A variety of whips and cutting edges can be fitted to the revolving cleaning head to remove even the toughest materials without damage to the silo, bin or hopper walls.

The equipment is mobile and can be easily positioned at a cleaning location. The light alloy boom is lowered into position, the standard unit has a reach of 6.4 m/21 feet from the entrance with a rotation of 360º, the 'Mini' system can reach 2.4 m/8 feet and rotate through 180º. The motor drive is attached to a flexible hose that can extend down to 45 m/150 feet (or longer if required).

This makes the Prima Whip™ system suitable for the majority of bulk storage and handling applications. Custom designed systems are also available.

With totally blocked silos, the Primasonics® Prima Lance™ Drill can also be used in conjunction with the Prima Whip™. Used to 'drill' through from underneath a completely plugged silo or bin, it can make a way for the removal of any remaining materials safely from the top using the Prima Whip™. The drill is inserted through an orifice in the base of the blocked container and is remotely operated using compressed air.

Both systems are featured in a technical brochure. A DVD showing them in use is available on request.
