Ball or bar mills- on what does it depend?comesa_web
The right type of mills depends on the mineral that will be processed and the product you wish to obtain. This is why a mill must have high flexibility in terms of length, the crushing means, and speed. With a bar and ball mill system, we can design and develop the correct foundations in order to adapt the mill to the client’s requirements.
The bar mill for dry or wet crushing is usually recommended when you require a thicker product (mesh range- 4 to 35).
One of their advantages is that they produce a very fine quantity in the product and also allow for one of the most economical means in size reduction when you have to prepare to feed the ball mills.
The ball mills can perform in open or closed circuits with classifiers or cones and be classified according to their discharge: by stump or grill. In comparison to bar mills, the reduction is an outcome of the specific contact instead of the linear contact.
The crushing with ball mills is not selective, they produce finishes with a 35 mesh and large scale particles. The ball mills generally perform with speeds slightly higher than bar mills, thus they generate a waterfall action in the center of the crusher.
Usually, they are recommended for a fine crushing that undergoes a single-phase, however, they are also widely used in conditions of massive re-crushing or continuously.
