Abstract (en)
Compacting of fine, air-absorbing powders such as refractory cements is improved by using a new type of vibratory tool having multiple solid projections (22) extending from a cap section (21) of the tool (10). By this means, need for a separate deairing tool and a separate, time consuming deairing step in the process is avoided, and the amount of dust introduced into the air is reduced.
