Simplex Continuous Concrete Mixer 



This machine combines the rolling principle of mix embodied in 

 all Batch mixers, with an absolutely accurate measuring device 

 and positive force feed. The revolving cylindrical drum is slightly 

 tilted, which allows for a rolling mix and gravity discharge. The 

 material is fed into the mixing drum through a three compartment 

 hopper equipped with a measuring device and force feeding attach- 

 ment which are graduated for any desired proportion. The drum is 

 sixty inches long, and on account of the slight tilt, the material 

 falls two inches toward the discharge end with each revolution. 

 Water is applied eighteen inches from the discharge end, providing 

 for a 21 time dry and a 9 time wet mix before the material is 

 discharged. The capacity of the machine is regularly from one to 

 ten yards per hour, which may be increased to twenty yards per 

 hour. It is equipped with 3 h. p. engine.

 It is equipped with regular or batch hopper, and made in either 

 side or end discharge type. Capacity, eight cubic feet, dry mix.
