Used for the purification of gaseous emissions from industrial processes, they are made of hot-dip galvanized sheet and are suitable for the treatment of fine, dry or low humidity powders, even in high concentrations. It is also possible to treat filamentary materials with direct discharge into the container, excluding the use of the screw conveyor or the rotary valves. They are available in a wide range of models with sleeves or cartridges. Particular attention has been paid to the design of each part of which the dust collector is composed, such as the proportional evaluation of the filtering battery in terms of upward volume and speed, the dimensions of the settling chamber and the relative flow lines, the air inlet and outlet sections with speed lower than 20 m/s, the inclination of the hopper higher than 45° and the optimization of the cleaning system (by injection of compressed air in countercurrent), obtained after numerous tests carried out to define the section of the jets, the optimal distance of the firing lances and the range.
The M30-M23 Series Hopper Dust Collectors are suitable for working in depression with a counter-current compressed air jet cleaning system with electronic control unit for the management of cleaning cycles according to real needs, ATEX certified "venting" panels EX II D. Standard unloading in trolley containers of different types.
The dust collector, put in depression by the aspirator, is crossed by the flow of dusty air, which enters laterally in the lower part of the main body, above the hopper, where, thadue to the considerable increase in section and the consequent decrease in speed,
