Xingbang gravel cost-effective production line

 

Nevertheless in order to improve the efficiency of energy-saving ball mill can increase its number of revolutions, but the blind pursuit of high rpm is not enough.Because when the improvement of the number of revolutions will bring some problems.From the ball mill design principle, if a critical number of revolutions or supercritical rpm movement, there will be two questions. 1: due to the centrifugal force leaving the mill lost the role of grinding; 2: Mechanical vibration and component wear due to the high-speed Games intensified, the useful life of equipment is greatly reduced. Row Mine will be thicker if the role of ball mill grinding, which will increase the mill sub-pole load, so that the product failed particles.And dielectric loss increased significantly.So, concentrator production speed rather than the critical speed of operation. Now introduced to improve the efficiency of current production in the most appropriate work revolutions: n = (0.76-0.88) 脳 critical turn number n.R min.Actual operation proves that the grinding media filling rate of 54%, the transfer rate is set higher than 76% of the critical speed of 88 & grinding productivity is higher; finely ground ore (feed size less than 3 mm grinding minerals below 0.1 mm), if the transfer rate set to 88% of the critical number of revolutions is clearly too high, affecting the quality, it should be slightly lower. Called low-speed transfer rate of the mill production is less than 76% of the critical number of revolutions, grinding; rpm higher than the critical number of revolutions 88%, known as high-speed grinding; rotation rate greater than 100 % is called supercritical rpm grinding.Production practice proves that the smooth lining of the mill, the medium filling the lower rate of between 30-40%, while appropriate to reduce the concentration of the grinding ball mill rotation rate increased to 100-104% of the critical number of revolutions, general to step down processing capacity increased by 10-30%.

     Production experiments show that the blind pursuit of disc revolutions is not right, only with some of these conditions in order to use the high-rpm grinding, but it is not optimal, will be one of disadvantages, therefore, not one-sided pursuit of high-speed ball mill . Xingbang Henan Machine Manufacturing Co., Ltd. Main Products: variety of large and small broken production line, stone production line and  alicey599 other mining equipment including Sand, crusher sand making models of crushing machine, jaw crusher The rod mill Sand, Impact Sand and ball mill series of energy-saving ball mill, cone ball mill, cement mill and ancillary products in the trough feeder, dryer, magnetic separator,rock crushercone crusher vibrating screen and other equipment.Henan Xingbang Machine Manufacturing Co., Ltd. is an import and export enterprises, the company is to produce small series sand making production line, sand making machine model-based R & D, production, sales as one to stock sand making machine manufacturers, the company The headquarters is located in Zhengzhou National High-tech Industrial Development Zone, has three branches, a research and development department.Since its inception, to advanced modern management system, Seiko production, independent innovation, bringing together a number of scientific and technological elite, now more than 500 employees, 20 senior engineers, more than 100 people in above-grade mechanic, the company's long-term home and abroad scientific research units, the introduction of domestic and foreign advanced technology, process and testing base.Pebble Sand, river gravel, sand making machine and other equipment according to the production of different materials; assist in the preparation of construction plans and detailed process; company to send technical personnel to assist free installation, all the requirements up to user satisfaction.Xingbang trends of the machine: based on the Central Plains, the world, set hundreds of long, for my own use, research and development with the promotion of social progress,Mobile Crusher high-quality product will offer the user!of refractory gold ores of ultra-fine grinding gold wrapped pyrite, microscopic gold,Rotary dryer submicroscopic gold cargo solid solution of gold-bearing ore, the insoluble Gold Extracted from a gold ore.Gold extraction,[rock crusher:http://www.xb-machine.com] the key is to undermine the the the pyrite parcels gold full dissociation.With ultra-fine grinding in South Africa deal with arsenopyrite and pyrite flotation concentrate calcine after roasting, Sec boiling.Researchers in the country have also done a lot of that vulgar type stirring mill, especially the vertical auger mixing mill as fine grinding equipment is even more superior.Low energy consumption, high grinding efficiency and recovery of gold. In addition, the vertical screw mixing mill (tower mill) in the leaching process of edging between the grinding media and mineral aggregate strongly peel grinding role destruction of the interface layer of a material particle surface diffusion, thus speeding up the chemical reaction rate .Edging leaching of finely ground particles constantly exposed to fresh, high reactivity of the surface, and it is now too late to passivation involved in the leaching reaction. The This not only accelerates a chemical reaction, but also improve the chemical leaching rate.
