The RETSCH 207440001 Disc Mill DM 400 is the perfect solution for fine grinding of medium-hard, hard, and brittle materials. With the ability to grind materials down to 0.05 mm, this comfort model offers improved safety features and convenient operation.
Built on the foundation of the well-proven DM 200, the DM 400 comes with automatic locking of the collecting vessel and grinding chamber for enhanced safety. It also features motor-driven grinding gap adjustment with a digital display, making it incredibly easy to operate. The clearly structured display shows all grinding parameters, keeping you informed at all times.
Designed with robustness in mind, the Disc Mill DM 400 can handle rough conditions in laboratories, pilot plants, and even online for quality control of raw materials. Thanks to its powerful performance, this model achieves the desired grind size in just a matter of minutes.
The function principle of the DM 400 is simple yet effective. The feed material enters the chamber from the filling hopper and is fed centrally between two vertical grinding discs. These discs generate comminution effects through pressure and frictional forces. The sample undergoes preliminary crushing and then moves to the outer regions of the grinding discs for fine comminution. The processed sample exits through the grinding gap and is collected in a receiver. The gap width between the grinding discs can be adjusted incrementally and even during operation.
The DM 400 has a wide range of applications. It can be used for grinding bauxit, cement clinker, chalk, chamotte, coal, coke, concrete, construction waste, dental ceramics, and more. With excellent crushing performance and convenient grinding gap adjustment, this product guarantees efficient and precise results.
Additionally, the DM 400 comes with several product advantages. It has a digital gap display for reproducible gap width setting, a TFT display with a robust membrane keyboard for easy operation, and a large, removable plastic funnel with smooth inner surfaces for easy cleaning and material feeding. The wear compensation of the grinding disc and the labyrinth sealing of the grinding chamber ensure long-lasting performance. With easy disc change and the option for a polymer interior coating, the DM 400 offers versatility and adaptability to meet your specific needs.
The DM 400 is the new comfort model for fine grinding of medium-hard, hard and brittle materials down to 0.05 mm. This model is based on the well-proven DM 200 but offers improved safety features due to the automatic locking of the collecting vessel and grinding chamber, as well as particularly convenient operation thanks to the motor-driven grinding gap adjustment with digital gap display. The clearly structured display shows all grinding parameters.
Thanks to its robust design, the Disc Mill DM 400 can be used under rough conditions in laboratories and pilot plants, as well as online for the quality control of raw materials. The powerful DM 400 requires only a few minutes to achieve the desired grind size.
Function Principle
In the DM 400 the feed material enters the dustproof chamber from the filling hopper and is fed centrally between two vertical grinding discs. A moving grinding disc rotates against a fixed one and draws in the feed material. The necessary comminution effects are generated by pressure and frictional forces. The progressively arranged grinding disc meshing first subjects the sample to preliminary crushing; centrifugal force then moves it to the outer regions of the grinding discs where fine comminution takes place. The processed sample exits through the grinding gap and is collected in a receiver. The gap width between the grinding discs is incremental adjustable and can be motor-driven adjusted during operation in the range between 0.1 and 5 mm.
Application Examples
bauxit, cement clinker, chalk, chamotte, coal, coke, concrete, construction waste, dental ceramics, dried soil samples, drilling cores, electrotechnical porcelain, ferro alloys, glass, granite, gypsum, hydroxyapatite, ores, quartz, sewage sludge, sintered ceramics, slag, soils, steatite, ...
