Cutter mill is a size reduction equipment consisting of a series of uniformly spaced knives (2 to 12 in number) attached to a horizontal rotor (rotating knives) which act against a series of stationary knives attached to the mill casing. The bottom of the mill has a screen attached to control the residence time of the particles inside the mill ...
Optimal hammer design and placement will provide maximum contact with the feed ingredient. Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 inches) thick.

Hammer Mill Crusher engaging in crushing various rocks and stones with comprehensive strength not higher than 320 MPa into fine and micro fine powders, is widely used in metallurgy, mining, chemical, cement, coal, sand-making, coal gangue, construction, refractory materials and ceramic industries.
Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).
Polymix / Micro Hammer Cutter Mill. Pulverizes almost anything from cotton and wool to rock samples; Versatile mill – can be fitted with either Hammer Rotor or Knife Rotor
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Dynamic spindle-speed and feed-rate for ball end mill 3D finishing Finishing 3D surfaces with a 3-axis machine and a ball end-mill can be challenging. In a single op, you can have the ball engaged near the tip where the SFM is much lower, and other times engaged near the side where it behaves more like a straight endmill -- and anywhere in between.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
Use high-speed machining techniques (light DOC and high feed rates) for stable and fast cuts where greater metal removal is required. Climb milling is preferred. When plunging with Ball Nose, use pecking cycle with a maximum of .002" FPT; maximum recommended depth is 30% of ball diameter.

When setting up a ball mill, it is critical to consider what is being milled. Keeping the mill cool and introducing oxygen scavenging materials will greatly reduce oxidation in a ball mill. Sealing the ball mill production chamber and flushing with nitrogen or an inert gas may help depending on the material that is put through the milling process.
