This machine uses mechanical drive and manual manipulation to put the mixed material into the mold box, and use concrete vibrating to shape the block. Products made by it have good looking, clear edges and corners, weight error is ± 3%, impact strength is as high as 10.5(MPa)and the error is 10%, geometry size <± 1.5 mm The machine has broad applications, it can not only produce concrete block, but also produce all kinds of load bearing and nonbearing blocks with industrial residue like coal slack, fly ash, sintered aggregate, waste gypsum, etc The machine, one kind of semi-auto-mastics block forming machine, which is developed and refined on the basis of Model 25 Automatic Block Forming Machine. On this machine, the directional, vertical vibrating device is adopted. So, it is quick in block forming and simple in operating, and the products made by it are perfect in density and excellent in strength.
