The 520 V type mill is used to grind various very fine products. Based on the principle of high velocity impact grinding, and thanks to control over the particle size by means of a dynamic selection system, which is built into the mill itself, it is possible to achieve a very high degree of fine material.
It is used with excellent results in the fine pulverization of:
- SODIUM BICARBONATE which acts as a reagent in incinerator smoke treatment lines, to neutralize acids which the smoke contains.
- SICILA RESINS
- ACTIVATED COAL
- PolyEthylene residuals
- GLASS
- INERT MINERALS
- OTHERS
Features
The PLC control automatically regulates incoming feed rates and main process parameters. The 520 V type mill is available in various sizes to suit the required throughput. These disintegrate materials which are not very resilient by shock against an impeller with stakes, and plastics by special rotating blades.
The stator is water-cooled. The feeder is prepared for the injection of liquid nitrogen when cryogenic grinding is necessary.
The dynamic high performance selector ensures high separation, up to 20 micron. Automatic piloting checks the operating parameters without human intervention. All the rotating parts have standard protection.
The filter is made of anti-static fabric, of a type chosen according to the dust, with automatic washing in counter-current compressed air. Control panel with starters, ammeters, automatic pilot and instrumentation. On request: vacuum indicator displayed on the panel – indicator of capacity displayed on the panel – temperature probes.
The systems are appropriately soundproofed, with a noise of less than 85 db (A) and are fitted with anti-explosion safety devices. They are made of Carbon Steel – AISI 304/316.
