7.2Sharpening the knives

Always take great care when sharpening the knives since they are very sharp and can cause personal injury.

7.2.1Overview

NOTE: Use the services of a skilled person when re-sharpening the knives and only sharpen the edges marked with the special sign! (see diagram under 7.2.2 and 7.2.3)

The knives must be sharpened so that the correct grinding angles are obtained, otherwise the granulator will not operate effectively with lightly cutting knives.

During sharpening, the knife must be cooled the whole time with plenty of water and must definitely not burn or start blueing on the edge since this means that the knife lacks durability and stability. If this occurs, the knife cannot be repaired by further grinding down or grinding away of the blued or burnt colour. The tempered knife may have deep deformations with possible cracking as a consequence.

The following instructions apply only if you are using CONAIR MARTIN'S sharpening fixture SF 79. The sharpening fixture is intended for use in a surface grinding machine and should be fixed on a magnetic board.

7.2.2Sharpening the fixed and rotating knives

Fixed knives:

NOTE: Only the surfaces marked with the special sign should be sharpened. The specified measurements apply when sharpening the

knives.

•The fixed knives are fastened as shown in the figure opposite (A) and the relief angle, 200, is sharpened.

•The knives can be sharpened only as much as is shown in the figure opposite. After that, they are worn out and should be replaced by new ones in order for the granulation to be effective.
