Abstract: A fluent ceramic material is provided under pressure to a plurality of piston and cylinder devices for the purpose of dispensing drops to form balls of ceramic material. The piston and cylinder devices are each provided with a nozzle positioned above a droplet catch basin containing an aqueous gelatinizing solution. A cam mechanism controls the stroke of a piston in each cylinder so that a specific amount of the fluent ceramic material from the storage tank is dispensed in drops from the nozzles into the droplet catch basin. The use of the cam mechanism ensures the dispensing of a specific amount of material from the nozzle corresponding to a desired diameter of the resulting ceramic material ball. The desired diameter can be easily changed by appropriately changing a cam disk of the cam mechanism. The rate of production can be appropriately increased or decreased by increasing or decreasing the cyclic rate of the pistons.
