The equipment is made up of two blades on two shafts that cut each other to meet the requirements of shredding materials. The size of the shredded material is related to the thickness and number of teeth of the shredded blade. The thinner the blade, the smaller the size of the shredded material. The more teeth the blade has, the shorter the length of the shredded material. The device adopts a low speed and high torque design, which has the characteristics of high shear force, good tearing effect, low noise, and good stability. 01.Chamber The chamber is processed as a whole, with small error, high accuracy, and reduced vibration and strain. Arc baffles are installed on both sides of the case to ensure smooth discharge and improve output. 02.Shaft and Blade It is made by multiple heat treatment and low temperature freezing heat treatment processes, with good overall toughness and hardness, ensuring cutting performance and service life. The fixed tool is installed by hook to optimize the tool replacement efficiency. 03.Bearing seal The bearing pedestal adopts the method of assembling and disassem-bling, which is convenient to remove the moving knife, fixed knife, bearing and other parts, easy to maintain and replace the tool, and the sealing structure is used to block the broken material, grease, liquid material, and protect the bearing and gear, etc. Self-aligning roller bearing is adopted. 04.PLC PLC is programmed independently and equipped with start, stop, forward, reverse and overload protection functions. The overall automation ensures safety and stability and saves labor costs.
