Technical Data machine model designation: DM200 Use as intended The DM200 laboratory disk mill is suited for finely milling soft to hard materials (up to 8 Mohs) in sets or continuously from the fields of mining and metallurgy, rocks and earth, the glass industry or soil research. Our applications laboratory would be glad to give you further information upon request.
Protective Equipment The following safety equipment reliably prevents persons from unintentionally putting their hands in the machine when it is running. funnel tube designed in conformity with EN 294. This prevents persons from putting their hands into the milling space when the flap is opened safety limit switch. This prevents the machine from starting up when the milling space is open.
Emissions Characteristic Noise Values : Noise measurement in conformity with DIN 45635031-01-KL3 The properties of the material to be crushed also has an effect upon the characteristic noise values. sound level LWA = 81 dB(A) emission read at the workpiece LpAeq = 69,4 dB(A) Machine Dimensions height: 400 mm, 500 mm with the vertical flap on the funnel. width: 430 mm, 900 mm with door opened at 180°.
Transportation and Installation Packaging Packaging is in accordance with the transportation path and satisfies the generally recognised packaging guidelines. Please store the packaging for the duration of the warranty period because your warranty claim would be endangered if there were a complaint and it were returned in insufficient packaging.

Adjusting the Gap Width You may adjust the gap width between the milling disc in the housing and in the door just by adjusting the graduated rotating crank mounted below the motor. 1 graduation line = 0.01 mm. You may adjust the gap from 0.1 to approximately 5 mm. Rotating Crank Caution! Do not go below the minimum gap width of 0.1 mm. You may control check the gap width setting through a window behind the funnel tube by means of a sensing gauge.
Changing the direction of rotation, replacing the milling disks The milling disks are subject to natural wear after use over a long period. However, before they need to be replaced by new ones the direction of rotation of the motor can be changed so that the opposite side of the gear teeth can be used. By this means the service life of the milling disks can be extended. Changing the direction of rotation: By reversing the phases of the mains supply the direction of rotation of the motor can be changed.
Replacing the milling disk in the housing: Disconnect the mains plug Remove the collecting vessel Open the door Lift up the cover Unscrew the hexagon bolts or hexagon nuts with an SW 30 open-jawed spanner Remove the milling disk Clean the mounting of the milling disk Place a new milling disk in position The milling disk must have a level contact surface Screw in the hexagon bolts with washers – for zirconium oxide hexagon nuts are used.
General Information Accessories Cleaning You may pull out the collecting container for cleaning purposes. Open the door to clean the milling discs, the milling space and the funnel tube. You may now conveniently clean the entire area that has come into contact with the material to be crushed with the aid of a brush or vacuum cleaner. ! Do not clean the DM200 with flowing water. Danger from Current Surge Only use moistened rags. Solvents are not permitted.
Safety Regulations (Table) process safety information intended use for the DM200 from the sections action hazards property damage and personal injury may be incurred if the safety information is not observed. do not mill any explosive selfigniting or fire-promoting materials no claims to compensation for damage shall be accepted whatsoever do not mill materials whose fine proportion at a certain percentage may lead to an explosion.
