A venturi receives incoming material through an inlet tube and subjects the material to pulverization. The material, as it undergoes pulverization, is further subject to moisture extraction and drying. An airflow generator, coupled to the venturi, generates a high speed airflow to pull the material through the venturi and into an inlet aperture in the airflow generator. The airflow generator directs the received pulverized material to an outlet where the material may be subsequently separated from the air.

System and method for pulverizing and extracting moisture

A cylindrical casing () is disclosed which is of glass reinforced plastic and has an end cap at each end thereof. In the drawing the illustrated end cap is designatedEach end cap has at least one opening () therein through which water can flow. The illustrated end capis held in place by a mounting ring () embedded in the wall of the casing and encircling the casing internally. An internal groove () extends circumferentially of the mounting ring (). A first locking ring () having a peripherally extending external rib () is within the ringThe rib () is in the groove (). A second locking ring () fits into the locking ring () to expand it outwardly and press the rib () into the groove (). Stud holes () in the end cap () and in the locking ring (), receive studs () which secure the locking ring () to the end cap ().

Manufacture of casings for use in the desalination of water and the filtration of liquids

A venturi receives incoming material through an inlet tube and subjects the material to pulverization. The material, as it undergoes pulverization, is further subject to moisture extraction and drying. An airflow generator, coupled to the venturi, generates a high speed airflow to pull the material through the venturi and into an inlet aperture in the airflow generator. The airflow generator directs the received pulverized material to an outlet where the material may be subsequently separated from the air. An acoustic emission sensor receives the resonant frequencies generated by material passing through the airflow generator. The resonant frequencies reflect a material flow rate that is adjusted to avoid an overload situation. An automatic balancer system couples to an axel rotating the airflow generator to provide balance, improve efficiency, and eliminate cavitation.

System and method for pulverising and extracting moisture

A pulveriser is disclosed which comprises a fan which sucks air through a pipe. A hopper receives material which is to be pulverised, the hopper having an open lower end which communicates with the pipe. Between the hopper and the fan there is a venturi. Air flows through the venturi at a speed of Mach 1 or above. Pieces of frangible material dropped into the hopper are sucked to the venturi where they are blown apart and reduced to powder.
