Mill experts about the impact on productivity of the mill speed

       Actual production, according to media movement theory to determine the appropriate operating speed milling machines are the critical speed of 76% and 88% while our current manufacturing mill transfer rate between the majority of 75% to 80%. Also suitable mill speed is determined by the temporary production compared. When comparing, do not just look at the level of the production capacity of the mill, but also the power consumption, steel consumption and economic benefits how. The results of a concentrator States on a series of 3200mm 3100mm ten temporary industrial scale ball mill speed comparison test was filling rate remained under 44% ~ 48% condition, ball speed by 18r / min speed was increased to 74.3% 19.8r / min speed was 81.72%, the whole plant in processing ore increased by 45,800 t but due to the increase in electricity consumption of 6.574 million kw h liners make more consumption 388.48t cost per ton of concentrate to improve the 0.38 yuan,Winnowing pulverizer Mill resulting in the whole plant all year speed is increased due to mill and less profit 567,900 yuan. That is, increasing output without increasing the conclusion is negative.
        Grinding media in a state of motion depends on the cylinder body mill speed. Motion state of the medium is different, when other conditions remain unchanged. Grinding effect is not the same. At low speed milling machines, medium spilled off the movement-based, High Pressure Grinding Mill small impact effect, mainly for grinding action grinding mill production capacity is low, suitable for fine grinding; at high speed, medium Paola sports increase the proportion of the way, the impact of the role of strong grinding effect to the impact of the main grinding stripping followed conducive coarse crushed material, milling machine high production capacity. Mill filling rate is different, the maximum useful power reaches the desired speed is not the same. Filling rate is higher, in order to ensure the innermost layer can be in the falling ball movement, requiring higher mill speed, ability to make useful power reaches the maximum, so that the mill has the greatest productivity.

Mill excessive heat is what happens

General mill equipment during operation will meet this kind of problem, but many problems are easy to solve, sometimes some small problems, then the customers themselves can be solved, but sometimes customers are solving some of the problems not need to consult the manufacturer before they can solve a lot of problems here, including,High Pressure Grinding Mill where mill work time for fever and serious problem for everyone to talk about solutions.
Mill grinding room temperature is too high how to do? The reason why grinding chamber temperature will rise, because the mill after a long period of use, the sealing condition of the equipment will continue to decline, causing the leakage of lubricant, not only the temperature of the bearing increases, the flexibility of operation is decreased, and also contaminated material, the user needs to take the necessary measures to prevent the temperature of the mill grinding chamber excessive increase in problems. Specific measures are as follows:
Pay attention to the work of the state mill lubrication points, such as part of the bearing, roller, etc.,TengFei Ash Calcium Machine to regular meals to lubricate part refueling, ensure that equipment components in good working environment, increase the flexibility of the parts operation, reducing the contact surface of friction between extend the life of equipment, thus avoiding the problem of grinding indoor temperature is too high. According to the working conditions, can be appropriately adjusted in the milling chamber ventilation, the ventilation duct opens, and grinding of the external air flow of indoor air convection occurs, so that the grinding room temperature was slowly reduced to avoid the device to avoid the milling chamber temperature.

The role of micro-grinding limestone processed in different areas in which

Limestone is limestone ore processing micro-grinding the ore out of the use of ultra-fine powder, a powder is widely used one. Limestone can be used in different micro-grinding fineness of powder is applied to the processing among different areas. What are limestone uses it?
After limestone processed can be mainly used in the field of rubber, plastics, paper, coatings,High Pressure Grinding Mill inks and pharmaceuticals, involving a wide range of high demand. Like to use the big white building, paint, glass, asbestos, cement, lime which are more or less containing limestone powder, limestone powder which field of medicine is an important component of synthetic drugs, limestone powder can be used in the manufacture of the stomach and twelve duodenal ulcer disease antacids, acid poisoning antidote, and a tablet additives and so on.
In fact, the role of limestone in the industry, metallurgy and so on is quite important, high demand, high value. Want to produce limestone powder should use the appropriate micro-grinding processing, common Raymond micro-grinding, ultrafine mill are good limestone powder processing equipment,Ash Calcium Machine product fineness freely controllable, which is applied to the above areas are no problem.

High Pressure Grinding Mill in addition to the upper

High Pressure Grinding Mill in addition to the upper end of the sliding bearing spindle , the other transmission parts with bearings, and therefore must be run under good lubrication conditions , otherwise it will damage the bearings and shorten life. Maintenance is as follows : Spindle refueling time once per shift , it must be noted , found oil in the oil cup no loss or loss is too slow , you should immediately wash the oil channel , plus 50 # machine oil, spindle oil cup in the upper position , the spindle pedestal bearings , roller shaft bearings with grease gun filling each class 3 # lithium grease once every six months apart analyzer bearings cleaned once , add a little 3 # lithium grease , lithium plus room fan bearings grease. Non- metal block into the Ash Calcium Machine , otherwise it will damage the grinding roller and grinding ring , or even the center hanger .
 Raymond mill feed should be uniform, not erratic . Excessive feeding duct will be blocked , reducing yields, easy to burn out the motor , charging too little will feed production. Feed size : hard materials in the appropriate diameter less than 15 mm , soft material for 20 mm diameter , non- bulk materials added to the machine .
