26 / June 2021 powderbulk.com To determine which type of size reduction equip- ment you should use, consider the following questions. 1. What is the material that needs to be broken down? 2. How hard, big, and abrasive are the material's particles? 3. Is the material prone to moisture absorption, clumping, or any other quality changes? 4. Does heat or cold affect the material? 5. What is the desired particle size? 6. Do the particles need to be uniform in size? The answers to these questions will help you deter- mine whether adding a lump breaker to your process is right for your pneumatic conveying system.

A belt feeder or screw conveyor allows you to control the material feedrate, providing a more measured feeding method. You should also consider how quickly and to where the material will discharge from the lump breaker. If the material is fed into the lump breaker faster than it discharges, it can get backed up and jam the equipment, resulting in downtime. Upon exit- ing the lump breaker, if the particles are small and uniform enough, the material can proceed to down- stream process equipment, but if the particles aren't the right size, the material can also be recirculated back through the lump breaker. Lump breakers versus other size reduction equipment Lump breakers are best suited for use with pow- dery materials, such as cement, food, fertilizers, and solid chemicals, that tend to form unwanted clumps due to moisture or humidity. Mills and other crusher types are designed for more specialized size- reducing applications and materials, such as logs or heavy metals. Hammermills, another common size reduction equipment type, are usually used to crush, pulverize, grind, and shatter hard or abrasive materi- als. Other size reduction equipment types, including cage mills, grinders, pulverizers, and shredders, have specific applications as well.
