Raymond Jet-Stream Classifier
The Raymond® Jet-Stream™ Classifier is extremely well suited for use in closed circuit with a pulverizer. When used in this manner, it greatly improves the efficiency of the pulverizing operation.
Improved uniformity and fineness control of the product
The Raymond® Jet-Stream™ Classifier design permits high turbine periphery speeds at reduced airflows, and allows for maximum control of both particle top size and distribution by varying these turbine speeds and airflows. Excellent control of average particle size to as low as one micron can be achieved.
Optimum recovery of product
Conventional fine classifying systems recirculate air, causing a greater amount of fine material to be entrained in the tailings, while the Jet-Stream Classifier uses a single pass airflow design.
Less thermal degradation of product
Once-through airflow provides for a cooler product because recirculated heat does not build up within the classifying system.
Improved feed introduction
Material is introduced into the air stream before it enters the classifier. This assures uniform dispersion of material in the air stream as it flows into the classifier and results in improved efficiency.
Secondary air recovery
Some irregularly shaped particles or sticky materials tend to agglomerate within the classifier tailings. The Jet-Stream Classifier introduces secondary air to the tailings cone, which helps recover those particles by cleaning the fine material from the tailings.
Flexible operation
Easily varied rotor speed and airflow results in immediate change and stabilization of the system. Systems with a high pressure drop and recirculation require a much longer time to reach equilibrium.
