PULVERIZERS

MODEL A PULVA Sizer 5-7.5 HP

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 HP or a 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 ÿneness 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.

All Pulva-Sizers™ are capable of wet milling feed materials and slurries.

MODEL B PULVA Sizer 15-25 HP

The Model B mill is equipped with a variable speed feed drive and is generally furnished complete with motors, starters, wiring and ready for operation. Recommended for use with main drive motors ranging from 10 HP 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” 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 Mare recommended for high capacity grinding where neness 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.

MODEL C PULVA Sizer 40-75 HP

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 HP to 75 HP, depending on the material being ground. The cover is hinged with a handle and a 4 swing bolts which allows 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 where neness of grind is no priority. In the gravity feed model, the feed material falls by gravity into the grinding chamber, where it will accept much larger lumps than the feed screw model. The Model C has three times the capacity of the Model B. This model can be set up for Cryogenic grinding to be used with one of our cooling tunnels.

MODEL D PULVA Sizer 75-125 HP

The Model D 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 cover is hinged with a handle of 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. This model can be set up for Cryogenic grinding with one of our coolingtunnels.

MODEL F PULVA Sizer 75-125 HP

The Model F is a fabricated Pulva-Sizer™ designed for very high production of granular to medium-ÿne grinding and milling. It can produce 75% higher capacities than our Model D and can be driven by 125 to 300 horsepower. The unit is furnished with a multi v-belt or direct drive. Due to the large volume of product involves the Model F has a simple hopper feed design and air conveying outlet. The cover can be easily removed for maintenance. The liner and screen are designed for easy removal and replacement. The Model F can also be fed with quad feed screws of 4”diameter. A gravity feed model is also available for the Model F Pulva-Sizer™.

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 e°ciency 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 instainless steel construction.All Pulva-Sizers™ are capable of wet milling feed materials and slurries.
