Check the following points during the test run: Perform test run of approx. 0.5 hours at no load: Particularly check temperature of the bearings, running noises, leakages at bearing points, vibrations etc. Perform trial run under load: Increase load gradually up to rated load. While doing so, check drives for rises in temperature, running noise, vibration, and leakages. Check function of the safety devices. Check for uniform and equal current consumption of the electric motors. Check that gearboxes run smoothly. Notice! Immediately stop the crusher plant by operating the Emergency Stop switch in the event of faults, inexplicable noises and movements! When no defects have been found during the trial run or all defects found have been eliminated the crusher plant can be put into operation. Retighten screw connections
Because of setting of the screw connections respectively the components, screws can become loose. The following mentioned screw connections of the crusher plant must be retightened after a first operating time of approx. 50 hours. Pay attention to the respective torque. Drive connections at the crusher plant: – Gearbox - drive – Gearbox - motor – Gearbox - gearbox holder Crusher housing - inlet side Crusher housing - outlet side Face connection pan - stageloader Attachments at the substructure with pan
Select tightening torque
Take the torque of the respective screw connection from the corresponding spare part drawing. If the spare part drawing gives no other information, the torques of table "Tightening torques - Screws resp. nuts with metric coarse thread DIN13" in chapter 5 are valid.
