spindle pulverizers have about twice the explosion frequency of bituminous grinding vertical spindle pulverizers. (Figure 1) Pulverizer Operation Mode: The suction operation pulverizers have a slightly higher explosion frequency than pressurized pulverizers. The trend is re-emphasized by the coal type. Sub- bituminous coals accentuate the ...

The Pulverizer is supplied complete with a 3 H.P. Motor, a starter, "V" Belt pulley, drive and mounting wires for 440 Volts, 3 phase A.C. 50 Hz. It is a self contained grinder, with a rotary disc, having a planetary movement in a vertical plane. This feature gives added life to the moving parts and produces a sample of uniform fineness.

Step 3. Set the correct pulverizer throat clearance. An over-sized pulverizer throat will require more than optimum primary air-flow to minimize coal rejects. The pulverizer "free annular jet" of vertically flowing airflow, in our experience, must be adjusted for a minimum of 7,000 fpm under normal operation. Throats that are
