A number of recent studies (1-7) have shown how foot orthotics should be made to best relieve pain under the balls of the feet. Unfortunately, many people with metatarsalgia, neuroma, callus, sesamoiditis or other causes of ball of foot pain have received orthotics that do not work as well as they should. This page will explain how orthotics for ball of …
3. Mill head 4. Trunnion liner 5. Bearing liner The best a ball mill can get FL has installed almost 4000 ball mills at locations worldwide – which has given us a unique insight into the stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example.
Metatarsalgia is a general term used to denote pain under the ball-of-the-foot. (the area just before the toes) This is a very common problem and one of the top three complaints we treat.

In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
