The main difference between a ball nose end mill and a flat end mill is the shape of their cutting heads. A ball nose end mill has a rounded tip or "nose" that is ideal for creating curved surfaces and 3D shapes. In contrast, a flatend mill has a flatcutting head that is suitable for milling flat or shallow surfaces.

WhatsApp: +86 18203695377The cylinder lengthdiameter ratio of rod mill is generally, while the cylinder lengthdiameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill.
WhatsApp: +86 18203695377The rod mill uses steel bars as the grinding medium, and the materials are in point contact during the grinding process. Therefore, compared with the energysaving ball mill, the rod mill has the characteristics of uniform ore discharge, which is suitable for production lines that require more uniform particle size, such as the rod mill grinding quartz sand, sand making and other production lines.
WhatsApp: +86 18203695377Modern wire rod mills are high speed mills capable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels.
