6.Working way of ball mill
To continuously operate the ball mill, the material to be ground is fed from the left through 60° cone
and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted
up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near
the top of the shell. In doing so, the solid particles in between the balls are ground and reduced in size
by impact.
7.Quality assurance
Quality factor is significant to Dongfang.For years,according to quality and environment management system,
specified programs and quality brochures,Dongfang cultivates a quality & inspection team to manage the whole
production process. And we passed ISO9001:2008 Quality Management System, ISO14001:2004 Environment
Management System and GB/T28001:2001 Occupational Health and Safety Management System.
