Installation 4 Installation 4.1 Transport The device is delivered on a transport pallet with a wooden cover. We recommend using a forklift or pallet truck for transporting the packed device. DANGER! Do not step under the transport pallet during transport. WARNING! Improper lifting can lead to personal injury or property damage. The machine is only to be lifted with suitable equipment and by qualified personnel. The guarantee excludes all claims for damage due to improper transport. 4.
Installation CAUTION! The weight of the disk mill is approx. 160 kg with grinding disks. NOTICE! Place the disk mill on a flat, stable surface. It may be screwed to this or a base plate. 1. The disk mill is screwed to the transport palette from below using 3 screws. Loosen the screws with a spanner (17 mm). 2. Lash the harness to a crane or another hoist. 3. Next lash the harness to the eyelets. 4. Using the crane, bring the disk mill to the desired position.
Installation CAUTION! Ignoring the values on the type plate may result in damage to the electrical and mechanical components. 4.5.1 Adapting to the mains The disk mill is delivered with a connection voltage adapted to the electrical system of your country.
Initial start-up 5 Initial start-up The disk mill is delivered with mounted grinding disks. Check the gap width before the first grinding. (See Ä Chapter 6.2 ‘Setting the gap width’ on page 23). After the disk mill has been set up as described in Ä Chapter 4 ‘Installation’ on page 17 and the mains plug has been plugged into the mains socket, the device is ready for operation. CAUTION! – Grinding disks must not touch each other.
Using the device 6 Using the device WARNING! If the grinding elements used are not original accessories, we provide no guarantee and exclude all liability for damage to the device. WARNING! Make sure before starting the machine that the grinding disks have been mounted properly and that there are not any loose parts inside the device. Failure to observe this provision will void the guarantee and releases us from liability for any resulting damage to the device or personal injury.
Using the device 6.1 Setting the minimum gap width The minimum gap width is limited to 0.1 mm in the condi‐ tion of delivery. A stop screw with lock nut is located at the back left of the sliding table, which limits the forward movement of the sliding table. This prevents the grinding disks from touching inadvertently. The minimum gap width has to be reset after every change or prolonged use of the grinding disks. Grinding disks may have different thicknesses depending on the wear.
Using the device 4. With a feeler gauge (if unavailable normal printer paper that has been folded once can also be used), set the gap to 0.1 mm using the rotary handle. This is set through a viewing gap above the grinding chamber (2). The feeler gauge can be inserted through the opening to set or check the gap width. The feeler gauge must only be lightly clamped and it must be possible to pull it out again by hand without any problems. 5.
Using the device 6.3 Grinding with grinding disks of zirconium oxide When grinding with zirconium oxide grinding disks, certain work precautions need to be observed: 1. Precise setting of the smallest gap. The disks may under no circumstances touch each other during the grinding. The local heating promptly causes tension fissures at the circumference. These fissures appear very quickly and are easily detected. 2.
Using the device 6.4 Adding material DANGER! Explosion hazard! – When grinding oxidisable substances, e.g. metal or coal, there is a risk of spontaneous combustion (dust explosion) if the proportion of fine particles exceeds a certain percentage. When grinding these kinds of substances, special safety measures must be taken and the work must be supervised by a specialist. – The device is not explosion-protected and is not suitable for grinding explosive materials.
Using the device 6.5 Taking samples Depending on the quantity of the ground material, be sure to use both hands when taking out the grinding stock con‐ tainer. Hazard of tipping! 6.6 Final fineness The final fineness that can be achieved depends on the selected gap width (approx. 0.1 mm to approx. 12 mm). The gap width determines just one dimension of the individual particles in the fine ground material.
