Designed to provide fast and accurate real time results, using combined non-contact eddy current and ultrasonic technologies to detect surface and sub-surface flaws of hot and cold mill rolls. Mounted onto roll grinding equipment, Rollscan systems can be used during and after roll grinding activities to effectively detect and quantify surface defects such as roll.Continue reading

A pellet mill is not designed to pellet these materials, let alone the animal stomach to digest them. The pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is usually located on the ground or main work ...

In this way, the tube is pulled rather than pushed through the mill.
