For a ball mill grinding OPC to a fineness of 3200 to 3600 cm 2 /g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an chaeng vertical mill grinding a similar product, the cost of wear parts depends on the .
7 – Radius Milling . Radius milling uses a 2D Contourlike toolpath to produce an external fillet. Using the 2D toolpath requires a Radius Mill, but you can accomplish similar results with a Ball Mill and 3D contour toolpath. 8 – Spot Drilling . You can use center drilling to create a conical shape on the face of your part.

Vertical Roller Mills This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers. Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and trans
Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Spiralshaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes.
Grinding on the ready2grind system. The modules in standard container sizes are delivered preassembled. The grinding process is the same as that of bigger Pfeiffer grinding plants. The above flow sheet shows the process of cement grinding as an example. Clinker and additives are ground, dried, and classified in the Pfeiffer vertical mill.
