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.

Temperature control


Air-cooled chiller

Using air-cooled dual-system chillers, which are mainly equipped with European, America, Japanese imported compressors, Danfoss and Eco-saving components, as well as high-efficiency evaporators and condensers, the normal temperature water is cooled through the compressor mechanism of the chiller to the set temperature to force the control of the operating temperature of each barrel and screw section of the extruder.

Die face


Forming die

A pelletizer

A. Molding die made of AISI 5140 material, the surface is plated with hard chrome to increase wear resistance and corrosion resistance.

B. Round stainless steel collecting ring outside the die.

C. High speed alloy steel blade.

D. Independent frequency conversion motor control box to control 2.5KW variable frequency motor speed to get different length pellets.

Electronic control system

Touch screen console


Vertical control cabinet

Adopt a window-style 10-inch domestic high-end, high-stability and reliable touch screen, plus a PLC programmable logic controller host, to implement precise control of the system, and realize PID tuning linkage of the main motor, screw speed and head pressure. The control operation function and main configuration of the system are as follows:

1. With the screw speed set on the touch screen as the standard, the PLC programmable logic controller controls the inverter to drive the 55kw main motor to realize the interlocking power control of the motor;

2. Control cabinet electrical devices, including contactors, air switches and solid-state relays, all adopt Chinese high-end brands, keeping the stability and reliability of the control system. Meanwhile, it has the functions of under-voltage protection and early warning, pressure protection and early warning, and realizes the protection and early warning function of 5℃~35℃working temperature set on the control cabinet itself.
