MODULAR AND INSTRUMENTED SPIRAL MILL FOR PERFORMING TESTS AIMED AT DEFINING, STUDYING AND OPTIMISING THE MICRONIZATION OF A POWDERED MATERIAL

摘要

A modular and instrumented spiral mill (10; 110) for the micronization of a powdered material (P), suitable for performing tests and trials aimed at optimising the dimensional parameters (D, H, d, D1, H1, H2, D2, H3, H4) and process parameters (Qv', Qm', Qv", Qm", VEL) which influence and determine the properties and the quality (DIS) of the micronization of the micronized powdered material (Ρ'), comprising: - a plurality of modular elements or modules (11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 24; 111, 112, 113), apt to define the configuration and the dimensions (D, H, d, D1, H1, H2, D2, H3) of relevant and essential zones and parts (30, 31, 32, 33) of the modular and instrumented spiral mill (10; 110); and - one or more sensors or measuring instruments (FL', FL", TP), placed in these essential parts and zones (30, 31, 32, 33) in order to measure the effective process parameters of the modular and instrumented mill (10; 110) in its use and functioning to micronize the powdered material (P); wherein these modules (11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 24; 111, 112, 113) are apt to be varyingly composed and/or assembled and/or replaced one with the other so as to compose and form the modular and instrumented mill in a plurality of different working configurations (10; 110). Thanks to this possibility of configuration in a plurality of different working configurations, the modular and instrumented mill (10; 110) allows advantageously the performing of a series of tests and trials of micronization in corresponding different working conditions and with different powdered materials, so as to succeed, through these tests and trials, measuring by means of these one or more sensors or measuring instruments (FL', FL", TP) included in the modular and instrumented mill the effective working parameters of the micronization process and examining the data and the results (DIS) of the tests and trials performed, in composing and forming the modular and instrumented mill in an optimal working configuration (10; 110) apt to optimise the micronization of a specific powdered material (P).
