TROUBLESHOOTING VIBRATION AND NOISE :  After a mill has been in service for some time, wear may affect the balance of the  rotor assembly causing vibration and noise. Another source of noise may be the V-belts which can slip due to  lack of tension or which may be worn causing a flapping sound. If the mill is repeatedly overloaded by feeding  oversize or uncrushable material, the hammers will deflect (or lay back) causing excessive wear. This wear  elongatesthe holes and reduces the rod diameters, permitting the hammers to hit the screen or other parts.  Change hammers and rods immediately and avoid improper feeding. LOSS OF CAPACITY OR PRODUCT SIZE :  This problem is largely due to wear of the grinding elements and  can be corrected by reversing the hammers and changing the screenor screen bars, if worn. CLOGGING :  Clogging can be caused by feeding material into the mill too fast or not conveying product away

OPERATION STARTING: Before starting the mill, inspect the grinding chamber carefully and turn the mill by hand to be  certain that it is free of all objects that may have found their way into the interior of the mill. Check the direction of  rotation to see that it is the same as indicated by the arrows on the sides of the mill or on our assembly drawing.  When you start the mill, let it obtain full speed before feeding any material into it. Lastly, let the mill empty itself  completely before shutting down. FEEDING:  Material fed into a Schutte-Buffalo Hammer Mill should be spread evenly over the entire feed width  and should be conveyed into the mill continuously and uniformlyat a rate not greater than what the mill will  handle. Bear in mind that surge feeding is inefficient,as it tends to overload the mill thereby causing the machine  to use excess power and possibly stall it. An alternate overload and under load,condition of operation will

from the mill fast enough. It can also be caused byworn parts thatare not grinding properly or due to excessive  moisture, oil, etc. in the feed to the ha
