The principles and characteristics of the lime mill

Henan Xingbang mill production experts with many years of mill research and production experience, I came up with the ball mill grinding unit Parking Note: except in emergencies, the normal plan parking, they should first stop to the mine, as much as possible to the grinding machine classifier ore drained so as not to affect the next car.Ore not much left in the classifier, the first stop for 5-10 minutes, so that fine-grained sink, and then open the grading machine, and then stop for 10-15 minutes, so that repeated so that two or three times the fine Shen almost grader ore close to the jaw crusher row to make a last stop.Of course, the main production site to determine the actual situation. Should be immediately after stopping the spiral classifier to enhance up to avoid being pinched.If you belong to the temporary parking of the mill shell leakage ore fastening should first stop to the mining.If too long, 5-7 minutes per parking is necessary to start the grinding machine to deal with the grader back to sand, or to the demineralizer may be killed back to the sand can no longer start.Grader should stop the water supply, otherwise they will be diluted slurry, so that rapid sedimentation of coarse particles, resulting in the return sand affect the fastening cylinder screw.Article Henan Xingbang summary editing, roller mills the first mill network, welcome to reprint! Mobile Crusher A: mill moving shaft how to optimize the transformation: Henan Xingbang about the mill motor selection programwe know the progress of the ball mill revolutions progress mill produced, but not one-sided pursuit of high rpm grinding.Due to the progress of the revolution, also thrown up some of the topics.

Such as ball mill now at less than the theoretical critical number of revolutions the design and manufacture, if the critical number of revolutions or supercritical rpm movement, [Mobile Crusher:http://www.xb-machine.com/Crushing_Machinery/Mobile-Crusher.html] one appearing to lose because the centrifugal force leaving the mill grinding effect; second because of the high speed Games mechanical vibration and component wear increased equipment service life is greatly reduced.The role of grinding ball mill internal damage, and row mine thicken, increase the grading load, so that alicey599 the product not meet the size requirements.And grinding media and liner wear and tear of the sharp rise.Therefore, Rotary dryer most of the concentrator produced work speed rather than the critical speed of operation.When the concentration of non-smooth lining, grinding ball crusher machine charge filling rate of 40-50%, the formula results closer to the actual.\n- Critical number of revolutions type: D-inside diameter of the ball mill.M the critical number of revolutions formula: n.= 42.2 / D? Turn / min critical number of revolutions of the ball mill and its diameter D is proportional to the cases, the critical number of revolutions of the absolute values ifficult to obtain, currently only the formula of the theory of the critical number of revolutions has been widely used. The outermost layer of the ball exactly in the mill together rotate with the cylinder instead of landing, when the mill revolutions known as the critical number of revolutions. Exceed a certain limit (high rpm) when the ball mill rotation, the ball rotates with the cylinder without landing, in the centrifugal operation.At this time the ball that there is no impact, the abrasive is very small so that the grinding of repose.When the higher number of revolutions, the height of the ball was promoted.Out of the cylinder, the ball up to a certain height along the parabolic trajectory landed in Paola state.Have greater impact into the falling point, the ore is mainly affected by the impact and crushing, grinding efficiency is highest.When the low number of revolutions the ball inside the ball was promoted to a high degree of small slip from the top of the ball charge, by the gravity of the ball itself roll down was spilled off the state, then the ball's impact is small, but the abrasive strong, the ore is grinding stripping broken destroy grinding effects Ministry.Mill turn directly determines the size of the effect of the state of motion of the cylinder body of the grinding media and grinding homework.
