1. Simple structure, smooth operation, and low operational cost; 2. The machine adopts the technology of crushing stones by stones and iron by stones, the machine's states can be freely switched, multiple functions of sand making, reshaping and stone crushing are realized in one machine, the wearing of parts is lowered by adopting the technology of crushing stones by stones, and the production cost is lowered; 3. Little energy consumption, high yield, big crushing ratio, energy conservation and environmental protection; 4. The machine has the reshaping function, the products are cube-shaped, and the packing density is big; 5. In production, stones can form a protection bottom layer, and the machine body is abrasion free and durable; 6. A few wearing parts, made of ultrahard wear resistant materials, have the characteristics of small volume, light weight and convenient replacement of fittings; 7. Due to the adoption of an air self-circulation system, the dust is reduced; 8. The machine is little affected by the water content of materials, and the water content reaches nearly 8 percent; 9. The main shaft bearing is lubricated by a thin oil station, and because an oil tank is equipped with a interlocking device, the automatic control and the accident alarming are realized; 10. The top cover is lifted by a hydraulic system, and the operation is easy and convenient
