"The road is long Come, happiness and earth." For artificial sand making machine , it is also exploring numerous times, numerous attempts, progress in the twists and turns in the hardships of growing. Initially, we used crushing machine + rod mill model to sand, not only consuming a lot of water and electricity, and the low yield of sand, stone powder with the water drain, waste. The emergence of vertical shaft impact sand making machine changed this situation. Vertical shaft impact sand making machine using stone at stone, sand stone blacksmith mode, first dosing cone material from falling, falling outside of the material will form a material curtain, then falling into the inside of the impeller centrifugal acceleration. That part of the material will be accelerated to the line speed 70m / s speed impact to the material curtain, which is part of the stone hit stone. Section and is part of the impact will slow down after the shock hits the week nursing board, forming secondary crushed stone blacksmith. Vertical shaft impact sand making machine is a high efficiency sand making machine, can be directed to basalt, limestone, granite, diabase, andesite, rhyolite, marble, gravel sand, described as "a clean sweep." Today, a new generation of crushing vertical shaft impact sand making machine can be described as broken, equipped with hydraulic clearance to maintain the system, variable frequency current control system, independent of thin oil lubrication station circulatory system, temperature warning system, is a modern sand making machine equipment, Shanghai Jianye JYS efficient Sand sand making machine is such a new crushing. With the development of crushing Sand, fineness modulus and gradation adjustment is not a problem, but the traditional rod mill figure less and less.
