Pulverizer mills are mechanical devices that grind various types of materials, processing them in batches or through continuous acceptance on a conveyor. Commonly known as hammer mills, they rotate and press the bulk materials into desired states ranging from very fine to coarse depending on the degree of size reduction required. Some pulverizers even heat, cool or aerate materials as they exit the machine. With several types of pulverizing machines types on the market, these crushing solutions see use across many industrial fields.

The Model A is designed for continuous production work, but its small size makes it ideal for laboratory and pilot plant use. It is a complete unit with motors, starters, connections and is mounted on a portable stand with casters. It is equipped with either a 5 or 7.5 HP motor, and a 1-3/4” diameter feed screw with a variable speed drive mechanism.
The Model A is also available with an overhead feed screw arrangement which has a single 2-15/16” diameter feed screw for handling larger feed stock and can take a feed size up to 2”. A gravity feed model is also available which is recommended for high capacity grinding where fineness of grind is not priority. The Model A can also be set up for Cryogenic grinding to be used with our 3 ft cooling tunnel.

The Model B mill is equipped with a variable speed feed drive and is generally furnished complete and ready for operation with motors, starters, and wiring. Recommended for use with main drive motors ranging from 10 to 25 HP, depending on the material being ground. The standard feed arrangement is dual feed screws of 1-3/4”, 2-1/4” or 2-15/16” in diameter. The Model B hammers are available in stirrup or blade type.
The Model B is also available with either dual overhead feed screws or gravity feed. The gravity feed and overhead feed screw models are recommended for high capacity grinding where fineness is not a priority. The Model B is our most popular production mill for capacities ranging from 1000 to 6000 pounds per hour. The Model B can also be set up for Cryogenic grinding to be used with our 7ft cooling tunnel.
All Pulva-Sizers™ are capable of wet milling feed materials and slurries.
The Model C is a relatively high-capacity compact mill. The rotor diameter is 18” and the grinding chamber is 14” wide. Recommended for use with main drive motors ranging from 30 to 75 HP, depending on the material being ground. The cover is hinged with a handle and 4 swing bolts which allow for quick access to the grinding chamber. The Model C can be either direct drive or belt driven and the dual feed screw arrangement can be supplied in either 2-15/16” or 4” diameter.
A gravity feed model is also available and is recommended for high capacity grinding of bulk materials where fineness of grind is not a priority. In the gravity feed model, the feed material falls into the grinding chamber, which can accept much larger lumps than the feed screw model. The Model C can have up to three times the capacity of the Model B and is the most popular configuration for Cryogenic grinding with one of our cooling tunnels.

The Model D is the workhorse of our line. Recommended for use with main drive motors ranging from 40 to 125 HP depending on the material being ground. The 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 in either 2-15/16” or 4” diameter.
A gravity feed model 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 a chute or conveyor. The Model D can be either direct drive or belt driven.
Other feed arrangements include the horizontal feed opening designed for pneumatically conveying feed material and the vertical feed trough designed for gravity feed using our standard cover. The VT is used frequently in the carbon black industry. The Model D is designed for very high production and can be set up for Cryogenic grinding with one of our cooling tunnels.
All Pulva-Sizers™ are capable of wet milling feed materials and slurries.
The Model F is a Pulva-Sizer™ designed for very high production of granular to medium-fine grinding and milling. It can produce 75% higher capacities than our Model D and can be driven by 125 to 300 HP. The unit is furnished with a multi v-belt or direct drive.
Due to the large volume of product involved, the Model F has a simple hopper feed design and air conveying outlet. The cover, liner and screen are designed for easy removal for maintenance and/or replacement. The Model F can also be fed with quad feed screws of 4” diameter or a gravity feed model is also available.
The Model F Pulva-Sizer™ produces grinds that can be exactly predetermined as on any of our smaller capacity mills. It is a high-speed, close clearance hammer mill that shares the efficiency and high thru put of the standard Pulva-Sizers™. The Model F is capable of wet or dry grinding, and can be supplied with a wide range of hammer and screen types. It is also available in stainless steel construction.
