Model D Pulva-Sizer

The Model D pulverizer is the workhorse of our line. Recommended for use with main drive motors ranging from 40 HP to 125 HP depending on the material being ground. The pulverizer cover is hinged with a handle and 4 swing bolts which allow for quick access to the grinding chamber. The dual feed screw arrangement can be supplied either 2-15/16" or 4" diameter.

A gravity feed model of the grinding mill is also available which is ideal for grinding lumps up to 6" in size, depending on the nature of the material. Feed can be controlled by chute, vibrator, or conveyor. The Model D can be either direct drive or belt driven.

Other feed arrangements for the grinding machine include the horizontal feed opening designed for pneumatically conveying feed material and the vertical feed trough is designed for gravity feed using our standard cover. The VT is used frequently in the carbon black grinding industry. The Model D is designed for very high production.

All Pulva-Sizer® Hammer Mills are capable of wet milling feed materials and slurries.
