Sizing Toxic Corrosive Chemicals

An international chemical manufacturer approached Quadro to develop a completely contained processing environment for chemical intermediates. The requirement called for a highly toxic and potentially corrosive material to be milled and then dried before being conveyed to a reactor. No ambient air introduction was permissible, due to the highly corrosive nature of the product if it becomes moist. Dust was also an issue as the intermediate becomes toxic if inhaled. The dried product contained soft lumps up to 6" that plugged the inlet of the pneumatic conveying system as well as intrinsically fine particles < 44 micron. The customer was looking for a size reduction device capable of producing a lump-free final product of < 0.25". Due to headroom constraints, Lumpbreakers, Hammermills and Screen Mills could not be used.

To meet the needs of the customer, Quadro employed the Underdriven Comil®. The high-capacity, low dust Comil® successfully contained and processed the material to 100% of the required target < 0.25". The Comil® met the customer's required lead time and worked perfectly with their vertical space constraints. An additional benefit realized by the manufacturer is the low maintenance design of the Underdriven Comil®. The easy-to-maintain features allowed for quick turnovers resulting in long uninterrupted production campaigns without having to open the system and exposing the operators to potentially hazardous environmental and health concerns.

Ten (10) fully scalable Quadro® Comil® models are available for a variety of applications, and dependent upon product capacities can range up to 54,500 kg/hr (120,000 lb/hr). Meets all international safety standards including OSHA/CE/ATEX, and is manufactured to cGMP standards.
