The standard hammers used in our mills are double end reversible types, which have four wearing edges. When hammers become dull to the point where the machine is not grinding efficiently or when the hammers are well rounded, turn the hammers so a new sharp edge will be in service. One row of hammers should be turned at a time so the rotor balance will not be changed. Do not allow the hammers to wear too far or you will lose the opposite two cutting edges. Hammers can be changed through the access door in the mill with the hammer rods sliding through the access doors on the sides of the mill top, or through the main access door.
The hammers installed in your Schutte Hammermill mill were carefully balanced at the factory. Los nuevos juegos de martillos de repuesto enviados desde nuestra fábrica también están cuidadosamente equilibrados y cableados en filas. Siempre trabaje en una fila de martillos a la vez y no intercambie martillos de una fila a otra. El manejo descuidado de los martillos puede causar vibraciones excesivas.
Instrucciones de instalación: Equilibrio mediante el método del reloj
Nota: Al llegar,, observe que cada fila o conjunto de martillos está numerado en el martillo superior. Están numerados 1-8.
- Comience con la fila marcada como '1'. Como se ilustra en la Figura #1, inserte un martillo entre cada disco alterno. (En algunos casos, dos martillos se colocarán entre cada disco, dependiendo del estilo del rotor).
- La fila 2 seguirá con los martillos colocados de manera escalonada entre los discos, opuestos a la fila anterior. (Ver Figura #2)
- Continue installing the hammers in this manner working around the rotor in numerical order. (Ver Figura #1)
- Each hammer has four (4) wearing edges. Hammers should be rotated when the grinding edge wears to approximately half way between the hole and the original corner. Do not allow hammers to wear beyond this point or you will lose the ability to utilize all four edges. (Ver Figura #3)
- It is recommended that you replace the hammer rods when they show signs of wear (as a general rule of thumb, replace the set of rods following the usage of all four edges of the hammer). When rotating the hammers, check for premature wear to the rod itself. Excessive grooving of the rod will indicate a need for replacement.
- Install collars or cotter pins in the end of each rod following hammer rotation or replacement.
