Operation
Commissioning of the crusher plant
The commissioning may only be executed from authorized and specially trained personnel.
Notice! Observe the notes given in the respective operating manuals of the crusher components additional, e.g. motor, gearbox etc.
Before commissioning
Execute the following work before commissioning: Important! Check the oil level of the gearbox and fill up if necessary!
Clean the crusher plant and the working area from tools, all aids, etc. Check all screw connections and fastening elements (bolts, etc.) for tight seat, especially at the impact roll and the drives. The impact roll must be free to rotate. At crushers with height-adjustable roll the spacing plates fitted must be of the same quantity and thickness on both sides. The roll must not grind against the side wall of the housing. The distance to the housing wall must be the same over the whole circumference. The minimum distance between the top surface of the conveyor and an impact head with the roll in its lowest position is approx. 40 mm at the outer edges. Existing protecting devices must be assembled respectively fastened according to instructions. All lubricating points must be filled with grease sufficient. Only then a faultless lubrication is possible from the beginning. If any: Check the hydraulic fittings and hydraulic lines for leakages and damages. Check the correct installation of the supply lines. Check all hydraulic connections. Danger! Percussive hydraulic hoses can cause very serious injuries or even death!
After eliminating all founded faults the commissioning of the crusher plant can be executed.
Notes for electrics
The crusher plant is supplied without electrical equipment. It is the responsibility of the operator to arrange for the installation and availability of all necessary functions. Please observe the applicable regulations and guidelines for the electrical system. Additionally, follow the general requirements mentioned below and observe any special regulations which may apply for the respective application.
Actuate acoustic and optical start-up warning signals before starting the crusher. All persons who may be in the hazardous area should be given enough time to leave the respective area before the roll is allowed to start rotating. The drive of the crusher roll must always be actuated before starting the conveyor drive. The conveyor drive is only allowed to start when the crusher roll runs at rated speed. W hen a Turbo coupling is installed, the electric motor should be switched on directly. If this is not possible, a change over from star to delta connection must take place within 3 seconds. The conveyor drive must stop automatically when the speed of the roll has dropped to 90% of its rated speed. The roll drive must stop when the limit temperature of the Turbo coupling is reached and/or the fusible plug actuates. The conveyor and roll drive must stop immediately if the conveyor chain fails/breaks. The conveyor drive must be stopped before the roll drive. The roll has to continue running for a short while after the conveyor drive has been switched off. All drives must stop immediately.

Test run and start up
Danger! During the test run no person may be in the danger area of the crusher plant. There could be faults, which have an effect on standard operation, e.g. assembly faults. Because of such faults very serious injury or even dead can be the result! Warning! For safety reasons there should always be at least two persons when performing the test run. The valid safety instructions of the mechanics and electrics must be observed! e.g.: - Never operate switches, valves, control devices, etc. unauthorized Danger! Always wear protecting helmet, goggles, hearing protection, safety shoes and safety gloves!
