It is of great significance to improve the technical efficiency of grinding in the milling operation. So how can we improve the technical efficiency of grinding? To improve its consumption efficiency, we can think from the following aspects:
One, the use of different vertical grinding machine
Consumption theory proved that the peripheral discharge of ramon mill function increased over crushing. In particular, the mineral brittleness makes more sense. Because of the speed of these mineral grinders, sinking to the bottom of a large pulp density mineral particle is easy to discharge, and because of the temporary grinding medium parallel bars,
Such a view can be increased by grinding. In addition, due to the gloss of these exterior grinders. A small buffer of mud for the grinding medium. In order to grind the media can play an abundant role in breaking down these large capacity grinders. In the classification of equipment selection, the use of lockout plant, or pre-classification of fine screening has a certain disadvantage. With the grading of the equipment sieving fines. In order to control the size of the product grinder more strictly, such size can not be discharged, effectively preventing the "coarse" scene. Following high efficiency by sieving, about 80-90%, while with spiral classifier classifier rake usually only 40-60% of the classification efficiency. This can cause a scene in which the particles have been reconfined to the air and have shattered.
Adopt closed-circuit grinding process
A reasonable grinding process should be ground to a particle, once separated from the grinding machine, should be immediately separated from the discharge. On the one hand, to prevent on the other hand can make excessive wear, such as steel ball grinding medium is completely coarse in mineral particles, thus allowing the power can be done as useless as possible tasks. Yes, the existing grinding machine stop particle size grading, it is very difficult, this use classifier mill or fine screen separation qualified, coarse grinding machine mineral particle size, and then go to the mill (also called back to the sand). You can see in the block grinding circuit, grinding machine, ore for the new add back sand, so after grinding machine and more material after milling machine data in the slow pace. Short grinding time. In the block grinding circuit, coarse repeatedly failed to be ineffective, until after the machine grinding off. The second is to block the grinding circuit, because a lot of gravel into the coarse grinding machine, to the extent of the compound up. Grinding according to dynamic principle. Then, the energy is useless for the task, so faster grinding, milling machine consumption rate. In addition, the presence of sufficient sand back can eliminate a new grinding machine that consumes products on the ore scale. Indicate that closed - circuit grinding can be ineffectively prevented with "coarse" images. It makes grinding on the premise of ensuring qualified size, achieving average, coarse, reducing high-grade products, which is the next step in the sorting operation is unhelpful.
