EX-150 Spiral Ceramic Extruder For Making Activated Carbon
A. Features EX-150 Spiral Ceramic Extruder
Three years ago, we introduced and optimized the improved German spiral ceramic film extruder technology to meet the urgent needs of Chinese water treatment industry users. In addition to using more cost-effective manufacturing parts, the fully domestic extruder optimizes the replacement structure design of the breakable parts module to facilitate the daily maintenance of the extruder, optimizes the design of the vacuum exhaust structure of the extruder and eliminates the defects of the agglomeration and drying of the materials which affect the product quality.
Our company pursues the extruder design on the basis of high cost-performance and lower energy consumption. At the same time, we insist on the pursuit of high stability and reliability of the extruder operation process, the intuitiveness and convenience of extruder control, the convenience of daily maintenance. For this purpose, we have adopted supporting designs such as energy-saving frequency conversion control of the motor, windows control interface, and modular core components. We give full play to our company's first brand advantage in the service life of the heart parts of extruders in China, the barrel and screw of extruder core parts are made of special 17-4PH stainless steel, which has achieved ideal performance of high corrosion resistance and wear resistance, achieves the goal of longer extruder running time.
