Features: Adopts imported excellent tool steel, specially made blades, durable! The installation of blades is designed based on adjustable method. Blades can be sharpened once becoming blunt. It can be reused many times, long life. Blade saddle adopts cascade shear structure, which can divide whole crushing force and increase crushing force happened on contact. The saddle is made of T7 quality steel, which has moderate hardness and softness. It is not easy to break or wear. It adopts high strength screws (8.8) to fasten all parts. Main body of whole machine is made of A3 quality structure steel, which can contribute to stable performance of the machine. It won’t be affected by broken stuff even after a long time of usage. The shaft of the main body is made of one step boring machine in order to ensure that concentricity and the verticality. Every part of the machine is set with basic holes and surface for both rough and fine flow process. All parts can be exchanged easily because of their high precision. Assembled with heavy load bearing! Crushing chamber are made of double sealing device. Saddle and shaft are fixed by heat conglutinating assembled method, which is very advanced technology. It can ensure the gap of them less than 0.05mm in order to prevent powder dropping into bearing. It will avoid motor overloading, which is main defect of plastic crusher. The front and back panel of crushing chamber is double layer soundproof. The intermediate is also stuffed with soundproof material, which can reduce noise to a very low level. The machine is designed for easily disassembled. Discharging dipper, main body and the filter are fixed as basic holes. It is very easy to be disassembled and cleaned. It is also equipped with a washing chamber and a protection brake for blades in order to ensure safety while cleaning and adjustment. Motor is equipped with over-loading protection device, it is linked with power protection system in order to guarantee safety. Electricity saving, energy saving and excellent crushing performance! With wheels for convenient movement! Compacted design for less space!
