In the pendular(or multipass) modethe suspension passes through the same mill multiple times, traveling from feed tank to product tank repeatedly (Fig-ure 2b). In the cascade modethe suspension passes through two connected mills (Figure 2c).

High-Pressure Suspension Mill Production Line is mainly consisted of jaw crusher, bucket elevator, hopper, vibrating feeder, grinder, air blower, powder collector, dust catcher. When it works, big materials are crushed by jaw crusher, then the materials are sent into the hopper by bucket elevator, and then fed into the mill evenly by the vibrating feeder at the bottom of the hopper.
Haan, Germany – According to Retsch, the newly developed Mixer Mill MM 500 is the first ball mill with a frequency of 35 Hz which produces enough energy for efficient wet grinding of samples down to the nanometer range.. The benchtop Mixer Mill MM 500 by Retsch is suitable for dry, wet and cryogenic grinding of sample volumes up to 2 x 45 ml in one run.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.
We consider a cylindric ball mill, lled with small hardmetal balls and a suspension. By rotating the cylinder around its main-axis the suspension shall be mixed by the balls, which are lifted up on one side and then roll or fall back onto their own surface. The lifting is increased by nine steel bars along the cylinder wall. The problem is that the

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
