How to select and start up a fluidized-bed jet mill system

milling applications, a high-moisture feed material can flow poorly and build up on the grinding chamber wall, classifier wheel, and conveying line. This can reduce mill capacity and air-classifier performance. If your feed material's moisture content is too high, you may need to add a predrying step to reduce the moisture to a manageable level.

Pulse-Jet. Pulse-jet (P/J) or reverse-jet baghouses use compressed streams of high pressure air to remove particulate matter. During cleaning, brief (0.1 second) pulses of air are pushed through the bag, dislodging solids which collect in a hopper below. The recommended air to cloth ratio for these baghouses is between 3.25:1 and 4.0:1. Advantages
