TM 300 XL滾筒式研磨儀用于顆粒和粉末樣品的制備。滾筒式研磨儀可以通過使用相應的模塊而當做一個球磨或棒磨機進行濕磨或干磨操作，一個有效的工藝流程需要足夠數(shù)量的研磨球或棒。通常情況下*終細度可以低于20微米的。
TM300XL由安裝在一個堅實的帶齒輪電機鋼架上的出口漏斗和一組分離的篩網(wǎng)加收集槽。TM 300 XL鎖定和控制機制使得樣品的收集很方便。滾筒蓋子的快速解鎖機制可以方便取下清洗。

作用原理

In a drum mill the sample (usually pre-crushed material) is placed inside the drum with the grinding media (grinding balls or rods) and subjected to external forces. The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition. The drum, which contains the sample and grinding balls or rods, rotates around a horizontal axis. Whereas particles break more easily when larger grinding ball resp. rod diameters are used, smaller diameters lead to a substantially higher final fineness.

The motor of the drum mill incorporates a solid-state controller with internal overload protection which is used to set and accurately control different drum speeds.
