System and a method for micronization of solid particles using valvular conduit

A system for micronization of solid particles, the system comprising:

• one or more compressed gas lines provided with a respective compressed gas inlet;
• one or more powder feeders, each installed in a respective compressed gas line of the one or more compressed gas lines;
• one or more valvular conduit modules, each made of a series of valves connected via a same passage, wherein each valvular conduit module is connected downstream of the respective one or more powder feeders on the respective compressed gas line;
• a cyclonic separator connected with all the respective compressed gas lines connected with respective outlets of the respective one or more valvular conduit modules and
• one or more particle size analysers in combination with one or more directional valves disposed on the respective compressed gas lines adjacent to the outlets of the one or more valvular conduit modules wherein the one or more compressed gas inlets are configured to receive compressed gas in the respective compressed gas line;
• wherein the one or more powder feeders are adapted to feed powdery material to be micronized into the compressed gas flowing in the respective compressed gas line, thereby forming a powder-gas stream;
• wherein the one or more valvular conduit modules are adapted to:
• receive the powder-gas stream in a first modular valve of the series of valves, from the respective compressed gas line;
• split the powder-gas stream into two streams and facilitate collision of particles of the powdery material in the two streams, in each valve of the series of valves, thereby causing a particle size of the particles of the powdery material to reduce due to impact collisions;
• wherein the one or more particle size analysers are configured to analyse the particle size of the particles of the powdery material in a micronized powder-gas stream coming out of the one or more valvular conduit modules;
• wherein the one or more directional valves are configured to:
• direct a flow of the micronized powder-gas stream to the one or more valvular conduit modules for further size reduction when an analysed particle size is larger than a desired size;
• direct the flow of the micronized powder-gas stream to the cyclonic separator when the analysed particle size is equal to or less than the desired size;
• wherein the cyclonic separator is configured to segregate micronized powdery material from the micronized powder-gas stream.
