The TM 300 Drum Mill is utilized for preparing granules and powders through a grinding process conducted in either dry or wet conditions. This versatile grinder can function as either a Ball or a Rod Mill by employing the corresponding module. To ensure an efficient grinding process, it is essential to use a sufficient number of balls or rods. Depending on the sample material, a final fineness below 20 microns can be achieved.
The drum mill comprises a gear motor mounted on a robust steel frame, a set of separation grids, and a sample collector. The TM 300 is designed with a yoke and locking mechanism that facilitates easy access to the sample. Cleaning is made convenient by a quick-release locking mechanism, allowing effortless removal of the drum cover.
The TM 300 accepts sample volumes up to 20 l and is therefore also suited for upscaling processes.
The TM 300 stands out for its user-friendly features. The easy tilt mechanism facilitates the swift and uncomplicated emptying of the grinding jar. The removable sample collector simplifies the sample retrieval process, making it convenient for operators to access their collected materials.
The solid noise-protection hood contributes to a quieter and more comfortable working environment.
The TM 300 is equipped with an emergency switch, providing a quick and reliable means to halt the milling process in case of unforeseen circumstances, underscoring the commitment to user safety.
The redesigned drums and drum covers of the TM 300 feature improved handling, allowing the lid to be secured with just one screw for a perfect seal, even during wet grinding.
Process parameters like grinding time or start/stop are conveniently set via the TM 300's large display interface. Settings include:
Catering to various application needs, the TM 300 offers standard grinding drums ranging from 5 to 43.4 liters. This ensures that the mill is adaptable to a wide spectrum of processing tasks.
An optional separation grid provides convenient separation of balls and sample after the grinding process. It is suitable for grinding balls sized 10, 20 or 30 mm. A connection for dust extraction prevents release of dust.
The grinding jar comes equipped with a gasket, ensuring a secure seal for loss-free milling operations. This feature not only enhances the efficiency of the process but also minimizes the risk of material waste.

While the maximum sample feed size depends on properties like hardness and breaking behaviour, a particle size of approximately 5 mm is ideal for the TM 300. Larger sizes are acceptable but should not exceed 15 mm. For sample lumps which break very easily or for deagglomeration effects, a feed size between 20 and 30 mm is feasible. For such easy-to-process samples, the sample filling level may be increased to 20 l.
If special drums of stainless steel 1.4404 in sizes 21.7 / 10 / 5 l together with grinding balls of steel 1.4404 are employed, it is possible to carry out wet grinding in the TM 300. The total filling volume for wet grinding may exceed the recommended amount for dry grinding. It may be helpful to use a large number of small grinding balls to increase friction.
| Grinding drum | Mass of grinding balls | Grinding ball size (mm) | Number of rods | Optimum sample volume (l) |
| 5 l | 10 kg | <5 | 10 | 20 | 30 | - | 1 - 1.5 |
| 10 l | 直至 20 kg | <5 | 10 | 20 | 30 | - | 2 - 2.5 |
| 21.4 l | 40 kg | <5 | 10 | 20 | 30 | - | 4 - 5 |
| 43.4 l | - | - | 8 | 9 - 20 |
The user can set the grinding drums in five different positions which are secured by a screw. This ensures easy filling and emptying of the drum but also improves the mixing and grinding process. The largest rod module of 43.4 l cannot be brought into the mixing position due to lack of space.

Another application area of the TM 300 is Bond Index Testing. The Bond Work Index is used to assess the grinding efficiency and to calculate the necessary grinding power when choosing comminution equipment in the design phase of, for example, a mining plant. Precise determination of BWI is crucial for the accurate design and estimation of costs linked to the comminution process in industries like cement, mining or steel.
Both the Ball Mill and the Rod Mill module can be used for the process. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit.
The Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm. The sample needs to be pre-crushed to particle sizes as defined below.
The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm. The sample needs to be pre-crushed to particle sizes as defined below.

在滚筒式磨磨仪中，样品（通常为预粉碎材料）与研磨球一起放置在滚筒内，并承受外力。
球磨仪用于在干燥条件下通过撞击和摩擦对固体物质进行细磨。包含样品和研磨球的滚筒绕水平轴旋转。当使用较大直径的研磨球时，颗粒更容易破碎，而较小的直径则会导致更小的最终细度。
The ball and the rod mill basically have the same concept comprising either a 12''x12'' jar with grinding balls or a 12''x24'' jar with grinding rods.
The jar is attached to a rotating yoke which is driven by a motor and can be placed in three different positions: Upwards for loading, horizontal for grinding, downwards for discharging.
To carry out the Bond Index test the pre-defined number of grinding balls or grinding rods is required. The electronic control integrated in the drive is equipped with an overload protection and permits and controls different speeds.
During the grinding process the difference in speeds between the balls / rods and grinding jar produces an interaction between frictional and impact forces, which releases the required comminution energy. The interplay between these forces produces a very effective degree of size reduction.
