An agitator is a low-powered high volume pump - it is an efficient mixer A typical dispersion application (such as dispersing pigment to make paint) requires about 1 HP for every 10 gallons compared to an agitator application (such as thinning the pigment dispersion with solvent) requires about 1 HP

The difference between VFD and Soft Starter

The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed A soft starter reduces voltage not Hertz and as such the starting torque at 2-3 Hz is next to nothing The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz peak (Line) voltage met at 60 Hz

A mill used to crack grain or other types of friable materials may be called a cracking mill Mills used to flake grains or other products may be called flaking mills or flakers Roller mills used to grind in a feed mill are commonly referred to as a roller mill or roller mill grinder Double pair (two pair high) roller mills may be utilized in
