In addition to high impact SAG mill grinding, media is used in other types of milling such as the finer grind of ball mills, tower mills, vibration mills and regrind mills. Many variables influence the size reduction performance in a mill, including the media size, shape & quality, the properties of the incoming ore feed, the ratio of feed to ...
Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large ...

HIGmill high intensity grinding mill has a less complex and more compact process layout and flow sheet than other stirred media mills. The process comprises just a scalping cyclone, feed tank and pump, and the mill itself. The benefit of high power intensity and vertical installation is a very small footprint.
At Gainey Sharpening Service Inc., we can generate any point required on drills to manufacturer's tolerances or to our customer's print. We will manufacture or regrind all types of step tools to print. We also regrind all types of end mills including radius tools and ball nose, side cutters and stagger tooth cutters.
The regrind industry used to be all touch and feel. You had manual grinders who did it by hand. Over time the need for tighter tolerance's has increased as manufactures have required more precise regrinding processes. We were one of the first to adopt CNC tool and cutter grinding, and commit to the higher quality standards.
Our vertical roller mills, horizontal mills, hydraulic roller presses and stirred mills have for many years offered efficient milling and grinding, flexibility, cost savings and easier maintenance. Whatever the application, one of our robust milling and grinding solutions will be suitable for grinding all types of feed materials including hard ...
Services » Tool Reconditioning; Tool Reconditioning. Utilizing the same high-precision CNC grinding machines that are used in Guhring's manufacturing plants, our Reconditioning Division is well equipped to restore standard and special carbide and PCD tooling to its original factory quality, condition and performance.
The efficiency of the classifiers is also important when we look at the regrind circuit and not just the mills. Creating slimes is not going to help flotation. The achieved classification efficiency at full scale can be quite poor (in my limited experience). Simple preventative maintenance practices can make dramatic differences.
Why Regrind Tools? Regrinding or sharpening tools can return the cutting tool to its original performance capabilities. The main benefit of regrinding is saving money without sacing quality. The timing of regrind is judged or based by the quality of holes, surface roughness, cutting resistance and the extent of damage to the cutting edge.

Grinding Mills also know as Semi-Autogenous (SAG), Ball or Regrind Mills are used in the primary or early stages of pulverizing the ore in the process plant. This initial grind of the ore is typically completed in two or three stages. The mills are driven by large high horsepower electrical motors and the outer shell of the mill is lined or ...

Depends on your end mill requirement.. I have a reocurring G-10 job that i use regrind carbide end mills that went dull from a previous job, then dedicate the end mills to a rougher for g-10.. i get a few grinds out of these.. only taking no more than .005 off the dia and .03 off the ends at at time.
The Vertical Mill at Samarco operates in parallel with ball mills. The regrind is fed with the product from the rougher flotation of coarse and fine particles, with an approximate F80 of 120 m. The grinding circuit's product has a P80 of approximately 38 m. In the Vertical Mill, 15 mm diameter grinding balls of high chromium cast iron are used.
Another important aspect of regrinding is the strong electrochemical reactions occurring inside regrind mills. It has been reported that the interfacial chemical reactions of sulphide minerals during grinding can be affected by different grinding forces resulting in the formation of crystal lack, dislocation and the nascent surface (Hu et al., 2009).
