Agitation tanks
Agitation tanks are used to provide a storage reservoir for mixed batches of grout from the high speed high shear mixer.
Three main functions:
I) Releases any air bubbles trapped during the mixing process.
II) The agitation of the specially shaped paddles keep the mix in suspension prior to pumping.
III) The tank acts as a storage reservoir for mixed batches allowing a continuous supply to be maintained for the pump.
 Powered by either air motors or electric motors, the units are of robust design. A grout inlet pipe to connect to the mixer discharge is provided and mixed grout is passed through a screening basket to filter any large objects which could damage pumping equipment. Agitation tanks are available in different capacities.

Paddle mixing tanks
Simple mechanical mixing of materials can be achieved in paddle mixing tanks. These are vertically mounted cylindrical tanks with a motor drive unit that rotates a vertical shaft to which the mixing paddles are fixed. In the Colcrete Paddle Mixer the paddles are pitched to improve material movement and specially shaped to minimise splash. There are also baffles fitted to the internal walls of the tank to create additional shear.As additional service we also offer you larger mixing tanks, available to special order, e.g. 1000 litres capacity and hand mixers of 90 litres.The picture illustrates a 90 litre mixer that can be used both manually and with a petrol engine.
