Standart Specifications
a) Material and hardness specifications will be in accordance with the specifications stated by the customer.
b) DIN 1683 GTB 18 is the most precise for dimensional controls.
 
Inspection Of Materials:
a) It is accepted that the customer or its representative inspection Co. has the right to make tests and inspection on the quality of the supplied Grinding Media during manufacturing and or after supply

b) Entry to our factory for testing will be facilitated.
 
 
Documents Of Grindings Media and Tests.

Chemical composition, Hardness, Visual test measurement, Weight and Tolerance reports will be provided during supplying.
 
Packing Of Grindings Media.
Grinding balls will be packed in steel barrels as follows:


1. Between 15- 70 mm……. net 900 kg / Gross 918 kg ecah steel barrel
2. Between 80-100 mm…… net 850 kg / Gross 868 kg each steel barrel
 
 
Guarentee:

a) Wear resistance is guaranteed for 40 gr/ton for Portland cement production at 3200 blaine with mills working under normal conditions. Wear resistance is guaranteed for 25 gr/ton for raw meal production with raw mills working under normal conditions
b) Breakage Ratio :

0-3 % : No claim
3-10 % : Free Replacement of the quantity of the broken balls.
More than 10 % : Free replacement of the balls in which size the breakage occurred.
 
Geometric Form:

The balls have unified roundness. Maximum difference in diameter is as follows.

a) For balls 60 - 90 mm: -,+ 1,5 mm b) For balls 25 - 50 mm : -,+ 1 mm
