_ Dahua cement mill machinery (certified) _ Qitaihe City Mill provided by Gongyi City Dahua Machinery Co., Ltd. Gongyi City Dahua Machinery Co., Ltd. (www.dhqmj.com/) is specialized in the "mill, shredders, briquetting machine, dryer, brick" of the enterprise, the company of "honesty, hard service" concept provide you with the highest quality products and services. Welcome to inquire! Contact: Cattle Ocean Road. Three kinds of production of zircon sand powder milling time is 16 hours. 1, features dry grinding is: simple process, without the evaporation of water and reduce water pollution, particle size range is better. 2, wet grinding process: the best health, but in the actual production plants, especially the work of a sudden interruption (power failure, machine repair), because the proportion of zircon sand is too easily precipitate, is not easy to float, often will affect the product quality, and even the entire production line grinding minerals substandard, seriously affecting economic efficiency of enterprises. 3, dry, wet mixed grinding process: When this process is the preparation of zircon sand and dry grinding compound aids first time, to be coarser material particles reach a certain degree of fineness, then add water and grinding aid agent wet milling, grinding mill at the same time, the effect of this method is the best, the downside is increased by adding water aids in the process during the milling process. Experimental study of zircon sand mine ultrafine grinding process to provide more than three energy-saving ball mill, you can choose the best according to the actual situation and the user process plant product quality requirements. Experimental study of zircon sand ultrafine grinding process of the show: the size of large ceramic ball mill, mixing wet and dry grinding mill price is better, dry ultrafine grinding aids best when used properly, the best economic benefits. Zircon sand ultrafine grinding process is different, different mill product quality and economic benefits are different. Mill equipment is segmented by a clutch of maximum dynamic load values ??starting with the elimination of the gap is proportional to the fourth power of the time required, and inversely proportional to the square of the starting time, the mill start-up time (clutch engagement time) longer, more dynamic load small, but long start-up time will increase the clutch heat, reduce the service life of the clutch, a ball mill in addition to the starting process for some reason, since the driving motor may have twice the rotation frequency of torque, torque and power frequency harmonic during rotation moment, these transient moments are likely to excite torsional vibrations of mechanical systems, resulting in dynamic load, in addition, also as a result of too much starting torque, soft starter improper operation and the reasons for the gap and other gear, causing shock and vibration, resulting in dynamic load.
