The Raymond® Series 3 Imp™ Mill is a versatile and dependable high-speed air-swept swing hammer impact mill designed for fine and medium grinding of soft non-metallic minerals, coals, various chemical compounds, food products and other materials. Almost any solid material with a nominal 1 inch top size that is softer than 2 on the Mohs Scale can be effectively pulverized to a fineness from 1,000 microns to as little as 5 microns. The Raymond® Imp™ Mill system has the flexibility needed to allow it to both pulverize and dry the material simultaneously.
The Raymond® Series 3 Imp™ Mill system is the ideal solution to many size reduction applications requiring pulverizing of a variety of materials. A typical system consists of the Imp™ Mill with either rotary or vibratory feeder,elevated in-stream classifier, system fan and cyclone. This basic configuration has proven itself the world over.
Raymond® Imp™ Mill system with flash calcining
In addition to free moisture, some materials, such as gypsum, contain chemically bound water, which must be removed in order to change the physical characteristics of the material. This process, known as calcining, can be easily accomplished with a Raymond® Imp™ Mill system.
Essentially similar to flash drying, the Raymond® Imp™ Mill system with flash calcining is provided with a number of special features which make it suitable for the higher temperatures involved. Our experience in the processing of gypsum, by-product gypsum and waste wallboard provides our customers with a single source of equipment supply for processing gypsum and the manufacturing of gypsum wallboard stucco.
