6.Our study
High wear resistance performance and low consumption products:
a.Real elements, such as V, and Mo Ni, added in the casting process to increase the metal microstructures to improve the material wear resistance capability.
b.Feedback from our client mines for the trial testing. Our Cr, 10-12% grinding ball could achieve about 50% cost saving against with one international product's16% Cr in our client mine.
Long working life:
a.Our warmed machine oil technology could lead the hardness gap between center and surface is less than 1.5 HRC.
b.And also we utilize the control temper and control cooling technology.
c.All of these great improve the ball hardness anti –corrosion, impact value.
Customer design:
Flexible to design the grinding ball with reasonable hardness and impact value in a satiated the varies size grinding mills and different ores. Such as the force cooling grinding ball technology for the Cr 28 .
Microstructure Optimization:
We research and develop the different microstructure grinding balls as below :
a.M(Martensite) + S(sorbite)
b.M(Martensite) + T(troostite)
c.M + B (Bainite) or Baiite Grinding ball.
7.Operation manual
Dongxu products are widely used in construction, chemical industry, mining industry, thermal energy and machinery
industry. In order to improve the using efficiency, please note the following details:
1.Our products should be used in a rational way according to gradation of mill and grinding media, and fill rate. Please
control the raw material particle size and proportion of raw material and grinding media.
2.Please do not switch on/off machine frequently and keep enough materials during operation. Operating without
material is prohibited, please fill in the mill with materials before changing new balls.
3. Please open the mill door to cool down the balls before pouring them out in case of bursting.
4. Please don't mix Dongxu products with other brands in the same compartment.
5. If there is any anomaly, please inform us as soon as possible. Please do not open the mill door until our service
team reaches.
