Concrete Mixer With Double Shaft Concrete Mixer With Double Shaftis mainly composed of retarding mechanism, mixing chamber, worm gear pair, gear, sprocket, chain and bracket, etc.Through the chain transmission, the machine mixing pattern for motor drive axle shaft cone drive, cone by gear and chain wheel drives the stirring shaft rotation, mixing materials.Unloading transmission form for motor through a belt drive reducer, reducer by chain drive stirring the rotate, flip and reset,unload the material. The machine adopts three axis transmission design, the main transmission shaft is in the middle of the position of the mixing chamber both sides plates, so that increases the stability of the machine when working;Turn 180 ° when discharging, the drive shaft force is small, and occupied area is small.All the parts after precision machining, interchangeable and general, easy disassembly, repair and replacement blades for vulnerable parts.The driving is fast, reliable performance, durable. 一、 Summarize Model HJS - 60 double shaft concrete test using mixer is special test equipment designed and producted to cooperate to promote implementation the《concrete test using mixer》JG244-2009 construction industry standards issued by housing and urban-rural development of the People's Republic of China. 二、 Uses and using range This equipment is new type experimental concrete mixer designed and manufactured according to the JG244-2009 standards of the main technical parameters promulgated by the ministry of housing construction.It can mix the gravel, sand, cement and water mixture stipulated in the standards to form homogeneous concrete material for testing use, for the determination of cement standard consistency, setting time and production cement stability test block;It is the indispensable equipment in cement production enterprises, construction enterprises, colleges and universities, scientific research units and quality supervision departments laboratory;Can also be applied to other granular materials under 40 mm mixing use. 三、 Technical Parameters 1、 Mixing blade turning radius：204mm； 2、 Mixing blade rotate speed：outer 55±1r/min； 3、 Rated mixing capacity：（discharging）60L； 4、 Mixing motor voltage/power：380V/3000W； 5、 frequency：50HZ±0.5HZ； 6、 discharging motor voltage/power：380V/750W； 7、 Max particle size of mixing：40mm； 8、 Mixing capacity：Under the condition of normal use, within 60 seconds the fixed quantity of concrete mixture can be mixed into homogeneous concrete.
