Air-assist systems are designed to improve the throughput of hammermills. A hammermill grinds up wood, more wood can be ground up by pulling air through the hammermill. A plenum mounted above a conveyor is located below the hammermill. Most all material falls into the conveyor, air and some dust are pulled to a remote filter.
A properly designed pneumatic discharge system can increase production 300-400% over gravity dischage mills when grinding light materials to a fine particle size. Without air, dusty material will take the path of least resistance, typically out the feed chute.
system is essential to achieving top performance in many bulk solids grinding operations. This article explains how you can select a vacuum pneumatic conveying system to assist the operation of a hammermill or fluidized-bed opposed-jet mill. With many grinding mills — including roller mills, rotor mills, hammermills, air-classifier
Kice pneumatic conveying systems keep wood material flowing and biofuel operations growing. Comprised of industry-leading components, our systems can easily be expanded to include dust control, hammermill air assist, pneumatic conveying, and cooler air assistance for peak performance.
In this mill, particles are reduced mainly from mechanical impact by the unit's high-speed rotating hammers. When the unit handles low-density materials or grinds materials to fine particle sizes, it must be equipped with a pneumatic conveying system (making it an air-assisted hammermill) to aid the grinding operation. The conveying system does ...

Hippo Hammer Mill Size Recommendations. Check out the Baby Hippo small hammer mill and Hippo #1 hammer mill for smaller machines (5-10 HP) that are extremely affordable, yet have remarkably high output, and toughness equal to their larger siblings. Look into the Hippo #1.5, Hippo #47 and Hippo #57 hammer mills for medium size (15-40 HP) requirements. The 60 HP Hippo #69 provides big capacity ...
Hammermill Hammermill capacity should be designed to operate near full motor capacity. The addition of an air assist system on the hammermill will increase capacirty by 10-15% while narrowing the particle size distribution band.

[PDF]Sep 27, 2018 · The post-grinding hammermill should have adequate screen area per horsepower to process the entire ration without raising the temperature of the mash more than 10ºF during the grinding process. A positive or negative air assist system must be installed along with the hammermill to pull the material through the grinding
Consequently, the hammermill setup that works well for one will not necessarily work for the other. The following discussion covers such factors as tip speeds, hammer patters and position, horsepower ratios (to hammer and screen area), and air assist systems.
