The test mill runs with a circumferential speed of m/s. This is comparable with that one of the Hardgrove tester ( m/s), however, much slower than the velocity in technical coal mills of about 3 to 5 m/s. And the questions arise, whether and how the breakage and the material introduction into the gap depend on the speed.

The more loops (the better the effect, the better the deadline for the equipment) So you need to adjust the size of the colloid mill. Grinding gaps can be manually adjusted using an adjustment ring on the housing. The grinding tool consists of some standard radial teeth, that is, the rotor and the stator are closely arranged one behind the other.

For every test coal the mill was run at a range of gradually increasing roll grinding pressures from the minimum to the maximum available with nominal full load coal feed rate. This enabled identification of the first grinding pressure which produced 70% of product material less than 75 micron, which is the nominal standard for the industry.
