Cement Mixer Machine
Introduction cement mixer??Cement mixer , also known as concrete mixers, is used to cement, sand and gravel aggregates and water are mixed and mixed into the concrete mix machinery, mainly by the mixing drum , feeding and discharging institutions ,
water supply systems, the prime mover , transmission, rack and supporting devices and other components .
( 1 ) divided by practices and continuous operating cycle operations two.Formula feeding cycle operations , mixing , discharging three processes are at a certain time interval cycle , namely by mixing parts .Since the mixing of various materials have been accurately weighed , so mixing quality . Currently they use this type of practices.These three processes in continuous mode of operation is a long cylinder body continuously. Despite its high- productivity jobs over the cycle , but with the ratio of each material , the mixing time is difficult to control, so stir poor quality. Currently less use.( 2 ) by way of stirring mixing self- downs , forced mixing the two .Since the fall of the mixer is in a mixture with stirring in the rotating drum , with the drum rotating mixing blades inside the drum to improve the mix to a certain height , and then scattered freely down by its own weight .
So again and again , until the mix so far. .Drum mixer is forced stirring does not move, and the rotary shaft of the inner drum are opposed to forced stirring blade . This mixer good mixing quality, high production efficiency ; but the power consumption, and fast blade wear. Generally applicable to the slurry mixing dry hard .( 3 ) by way of a fixed device and mobile two.Stationary mixer is installed in pre-prepared on the basis of the whole can not be moved . It ‘s bulky, high production efficiency. Multiple devices used in conjunction with a large magnesite .Mobile mixer itself is driving the wheels , and the small size, light weight , so good mobility . Applied to small and medium sized temporary works.( 4 ) a promising material way of tipping and non- tipping two.Tilt- stirring drum by tipping discharge, rather than relying on the Tilt- stirring drum reverse discharge.( 5 ) by stirring drums of different shapes , there are pear-shaped , drum , double cone , disc vertical shaft and horizontal -axis circular groove five. The first three lines since the fall mixing ; latter two was forced mixing , currently less use.( 6 ) by mixing capacity of a large ( discharge capacity of 1000 ~ 3000L), medium ( discharge capacity of 300 ~ 500L) and small ( discharge capacity of 50 ~ 250L).
