New Standard Twin Shaft Concrete Mixer

Laboratory Twin Concrete Mixer is suitable for mixing ordinary concrete, light concrete and dry hard concrete. It can also be used in other industry laboratories to mix different materials. This machine is easy to operate, high mixing efficiency, small residual volume, and easy to clean. It is an ideal concrete mixing equipment for laboratory use. 一、 Uses and using range Laboratory Twin Shaft Concrete Mixeris 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.Twin Shaft Concrete Mixers 二、 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. 三、 structure and principle Mixer is double shaft type, mixing chamber main body is double cylinders combination.To achieve satisfactory result of mixing, mixing blade is designed to be falciform, and with scrapers on both end sides blades.Each stirring shaft installed 6 mixing blades, 120 ° Angle spiral uniform distribution, and the stirring shaft Angle of 50 ° installation. Blades are overlapping sequence on the two stirring shafts, reverse outward mixing, can make the material to clockwise circulate at the same time of forced mixing, achieve the goal of mixing well.The installation of the mixing blade adopts the method of thread locking and welding fixed installation, guarantee tightness of blade, and also can be replaced after the wear and tear.Unloading is with 180 ° tilting discharge.Operation adopts the combination design of manual open and limit control.mixing time can be set in a limited time. Mixer is 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. This machine is composed of a frame, a stirring device, a transmission system, a limit device and an electrical control system. The frame is the supporting part of the entire equipment, welded by channel steel. The mixing device is composed of a mixing drum, a mixing shaft, and a mixing blade. The mixing blade is fixed on the mixing arm and is integrated with the mixing shaft to form two sets of spirals. The direction is opposite, but the spiral ribbon mixing blade with the same lead and helix angle, the gap between the mixing blade and the inner arm of the mixing drum can be slightly adjusted. The transmission mechanism is composed of a reducer and a coupling. The cylinder limit device is composed of a locking pin and a positioning hole. The electrical control system has the functions of starting, inching, stopping and timing.Twin Shaft Concrete Mixer
