Abstract
Wet grinding apparatus including a grinding unit having outer grinding discs and an inner rotating grinding disc. A drive shaft is attached to the rotatable disc and extends centrally through one side of the housing. The other side of the housing includes at least one central inlet port for allowing introduction of slurry solution. In an in-tank or batch grinder, inlet ports are provided on both sides of the housing through each outer disc. Inner surfaces of the outer discs and both surfaces of the rotatable disc have a series of outwardly extending grooves which taper in depth from a central location of each disc to a peripheral portion of each disc. Gap adjustment mechanisms are provided to separately adjust the gaps between the outer discs and the rotating discs. Spring based connections are provided between the outer discs to allow relative, biased movement.
