Another benefit in positioning accuracy is provided by the encoder. While ball screws typically use a rotary encoder mounted to the motor for positioning feedback, linear motors use a magnetic or optical linear scale for position feedback. The linear scale measures position at the load, which gives a more accurate reading of the actual position ...

A: Yes, a ball mill can be used as a tumbling mill, but the reverse is not true. Tumbling mills are specifically designed for size reduction using a combination of forces, while ball mills are designed for grinding using impact and attrition forces. Explore the fundamental differences between these two grinding equipment and how they can impact ...
