In the design, taking into account the cost savings, convenience and practicality of various factors in the selection of the gear unit, the selection of the input hole, form the output shaft, which saves the cost savings and other parts of the coupling, but also eliminates installation and other issues. Design of this device is subject to the crusher, mill works inspired. Its working principle is: an electric motor and a drive sprocket connected through worm reducer, and deceleration. Driving wheel drive driven sprocket, driven sprocket tooth in turn connected with crushed, milled tooth drive operation. Crushers, shredders can be also crushed the ashes, but because both are high speed, resulting in difficult to collect the ashes, pulverizing apparatus of this design is to find ways to use the worm gear and chain drive move the secondary deceleration achieve very low speed. By supporting smash theory, study the characteristics of the material of the ashes, successfully designed to pick up close gray ash furn
