Technical data Machine type designation: PM400 Use according to the intended purpose Retsch ball mills are used for milling and mixing soft, medium-hard up to extremely hard, brittle and fibrous matierals. Both dry and wet milling operations can be carried out. Minerals, ores, alloys, chemicals, glass, ceramics, plant parts, soils, sewage sludge, domestic and industrial waste and many other substances can be milled, easily, quickly and without losses.
Protective equipment The PM400 is fitted with an automatic lid shutting device which prevents the machine being started in an unsafe condition. The machine can be started only with the lid closed. The lid can be opened only when the machine is at a standstill. Mode of operation S1 Operation with constant load, the duration of which is sufficient for the thermal steady state condition to be reached. (DIN VDE 0530 T1) Machine dimensions Height: up to approx. 1220 mm / width: 836 mm / depth: up to approx.
Transport and installation Packing Packing is adapted to the transport route and conforms to the generally applicable packaging guidelines. Please keep the packing material for the duration of the guarantee period since if there is a complaint and the machine is returned with inadequate packing your guarantee claim will be at risk. Transport The PM400 is to be lifted and transported only by the transport screws TS supplied with the machine. Fig. 1 Net weight of PM400 = approx.
Temperature variations It temperature variations are high (e.g. during air transport) the PM400 must be protected against condensed water. Otherwise the electronic components can become damaged. Intermediate storage Ensure also that the PM400 is stored dry during intermediate storage. Assembling F Assemble the PM400 on a firm base. Further parameters are given in the section „Technical data”. Net weight of PM400 approx. 290 kg The machine must be locked in position before starting up.
Important instructions: 1. Electrical connection without a protective conductor PE is not permissible. 2. The drive of your PM400 is fitted with a frequency converter. To fulfil the EMC directive this is fitted with a line filter and shielded cables to the motor. If your PM400 includes a fault-current protective system, fault throwing may result through the antiinterference wiring of the frequency converter when this is switched on (switching on takes place each time the milling chamber hood is closed).
Operation Connecting the power supply H Ensure that the voltage and frequency of your mains supply correspond to the values on the type plate of the PM400. Plug the mains cable in the receiving socket Au on the rear side of the equipment. Au Plug the mains plug into the mains socket. Switch on the main switch H If the values on the type plate are not observed this can result in damage to the electrical and mechanical components.
Emergency unlocking A key for the machine is included in the delivery with which the PM400 can be manually opened if there is a power failure. Remove cap K (I) Insert the (S) key into the O opening on the right-hand side. (II) To unlock the gear, the key must be pushed in further with some degree of force. While pushing the key in, turn it in a clockwise direction as far as it will go. The lid can now be opened. The emergency unlocking device must not be operated while the machine is running.
When grinding with 2 grinding jars, the two must be placed opposite each other. Each of the two unoccupied grinding stations must be secured with a clamping pin and a spider (see illustration). The safety slider function will otherwise prevent the device from starting.
Pull the red sleeve 6 upwards and clamp the grinding jar by turning the three-point grip to the right. Let the red sleeve 6 move downwards and lock audibly in place; if necessary, tighten a bit more by means of the three-point grip. It must not be possible to turn the three-point grip any further. 6 up = free The red locking sleeve, which is now in the locked position, prevents the threaded spindle from working loose. 6 down = closed Before starting the machine ensure that the milling cup is clamped.
Safety instructions when starting the PM400 The milling cup clamping device is easy and reliable to handle and has proved itself for many years. The basic precondition both for safety of the operator and for long service life of the machine components is conscientious clamping of the milling cups. Please consider that the PM400 is a milling machine with a very high power input into the milling material. For this reason the milling cups must be fixed conscientiously.
Power failure during milling Display 1 PROCESS INTERRUPTED POWER FAILURE START = CONTINUE START = FORTFAHREN STOP = DISCONTINUE If the mains supply fails during the milling process the milling operation is interrupted. All parameters are retained and the residual running time is stored. After switching on the machine again the instructions shown on the left appear in the display (display 1). You can continue the process by pressing the START button.
Stacking of 50 ml milling cups of type “C” It is possible to stack two 50 ml milling cups one on top of the other. For stacking an adapter is required, which is available as an accessory. M2 A1 Stacking procedure Place milling cup M1 in the milling cup plate Place the adapter A1 on the lid of M1 Place milling cup M2 in position Clamp the milling cups as described in the section “Clamping the milling cups”.
Milling cup identification All milling cups of type „C“ are easy to identify through the labelling area SCH1 which shows the article no. and material. Milling cup labelling by the customer In addition to the above mentioned labelling area you can stick one of the labels supplied with the machine or available as accessories on the area SCH2 marked on the milling cup – for labelling e.g. milling cup contents etc. The label is heat resistant up to 150°C and your inscription can be cleaned with e.g.
Use of the closing device for milling cups After filling the milling cups these must be closed with closing devices available as accessories. For milling cups with material inserts, ceramics or tungsten carbide use only closing devices which support the material insert of the milling cup lid. This is absolutely essential owing to the anticipated internal pressure.
Operation via the display unit of the PM400 The mills have a new, very comfortable operator control system. All relevant data can be entered or called via a graphic display with one knob operation.
