Milling material hardness under 7, humidity under 6%; The mill applies a vertical design, working mechanism: A grinding roller rotates around the vertical axis, swinging outward driven by centrifugal force, pressing the grinding ring, the blade is driven to shovel the raw materials and send them between the grinding roller and the grinding ring, the …
- The Ultra Centrifugal Mill FM200 can be fitted with an automatic feed device to ensure consistently homogeneous grinding outcomes and prevent the possibility of sample feed overload. - Ground samples are gathered in a collecting pan, facilitating easy and loss-free sample collection while preventing cross-contamination.
material only remains in the grinding chamber for a very short time, which means that the characteristic features of the sample to be determined are not altered. The ground sample is collected in the collecting cassette surrounding the grinding chamber or in the downstream cyclone or paper filter bag. Order data Ultra Centrifugal Mill ZM 200
