In recent years the rapid development of China’s construction industry, real estate, restricted and prohibited the production of solid clay brick, autoclaved fly ash brick turning waste into treasure, new wall materials become the dominant product. After preparation of the blank autoclaved fly ash brick in the process, made of various materials after stirring the mixture of ingredients, essential to go through a process- mixing mill grind mix. The disadvantage is that the old mill wheel scraper mechanism is simple, large grinding wheel, mixing is not uniform, long grind practice time, low productivity and energy consumption. To solve this problem, in recent years, countries in the world dedicated to the research and production of various types of high efficiency wheel mill. There are planetary, counter-flow types. Currently there are wheel grinding mixer, planetary mixer mandatory, wet wheel grinding machine, countercurrent mixer and other types of wheel mill.The new mill is a traditional mix material grinding and mixing equipment, which is the upper part of the main structure of t he central planetary gearbox connecting a pair of grinding wheels, one pair of inside and outside blades, a pair of rotor rotation stirred by Nianpan plane and cylindrical surface grinding wheel pressure and shear forces generated by the material crushed, while the upper part of the gearbox to drive outside of the blade within DRUM revolution and rotation of the rotor has conducted a rotation, so both the grinding and mixing rubbing role because it simultaneously kneading and mixing with a grinding effect o n the fineness of the product is very easy to control, so far, is still building materials, important equipment refractories, ceramics, chemical and many other industries in the material commonly used in the preparation processIts innovative structural features are: ① additional planetary rotor mechanism to achieve the revolution have both rotary agitation rotation function, mixing complex trajectory, stir high. ② through the addition of an upper planetary gear train realized, Drums, mixing blade, blade entire planet carrier of the revolution and rotation of the rotor with a motor drive implementation, greatly streamlining the mechanical structure and energy consumption costs. ③ according to the special needs of the industry, an additional seal cover, and laminated sid e dish, plate would add water feeding device all integrated on the cover, the mezzanine floor to the rim, the implanted loop piping hot, with thermal oil, steam or hot to achieve heating. machine can also have dust and stimulate volatile gases, heating, condensation and many other features.Redesigned the new mix mill fully functional after upgrading, productivity can be increased 2-3 times, changed a lot of the same old models just simply broken or simply rolling backward status quo in the past mixing func tion, greatly increasing the scope of application equipment, reasonable structure to streamline and reduce the total weight, significant savings in the cost of raw materials and energy costs, energy savings of about 30%. Saving social resources supporting the now easy to operate after the electrical control cabinet, simple installation and maintenance.
