  • Amazon Drill 1/2" Heavy Duty Low Speed Everything Else

    I need a powerful low speed drill to power my grain mill for brewing. The nice thing about this drill is not only does it have the power (7.5 amps) it has an adjustable switch so that I will never exceed the lowest speed. This results in a better crush with less tearing and exploding of the grains (that happens at higher speed).

  • Introduction to the milling technology with the bead mill

    It does not matter whether the power input which leads to the existing energy density is applied with a high speed and low torque or vice versa. With a given bead charge and dispersion time the dispersion result depends only on the amount of the mechanical power. The torque therefore depends directly on the flow characteristics of the millbase.

    A well implemented SAG control philosophy should be able to vary the mill speed in response to variations in feed characteristics. If the feed ore becomes softer then the mill control system should respond to reduce the mill speed. You may not need to keep adding grinding media either if the issue persists too long.
