Raw Materials Lab

Laboratory instrument for small productions of atomised powder / ceramic granulate. The slip by means of a pump is sent to a spray lance equipped with a nozzle and mixed with compressed air, obtaining a suspended mist inside the chamber. Inside the drying chamber, the nebulized mixture meets a flow of counter-current hot air produced by a gas burner. In this way a rapid drying of the fog is obtained, producing granules which are deposited by falling into the lower cone. The size of the granules obtained from the process can be varied within certain limits by changing the diameter of the spray nozzle, the temperature of the hot air, the pressure of the compressed air and the flow rate of the hot air.
The atomizer is supplied in two models:
– The SD-60 model with peristaltic pump, inverter and two-stage burners.
– The SD-60 PRO model with diaphragm pump, inverter and modulating burner.

The atomized product comes out automatically from the collection cone and the fine part of the dried material is sucked up and knocked down.

The cyclone discharge must be connected to a dust suppression system.
