1L Ceramic Internal Mixer | The 1-liter ceramic internal mixer is specifically designed for the front-end mixing of advanced ceramic injection molding processes such as zirconia and alumina. The Weibulen 1L Ceramic Internal Mixer has won the favor and praise of numerous ceramic customers due to its excellent wear resistance (surface hardness up to HRC 72-74), dead-spot-free cleaning, and outstanding safety performance.

I. Basic Introduction of the 1L Ceramic Internal Mixer:

Utilizing advanced coaxial separation technology, the rotor can be separated with one end face as the axis, breaking the bottleneck of traditional internal mixers. The 5L ceramic internal mixer is specifically developed and designed for expensive, high-hardness, and easily contaminated materials like zirconia and alumina. The inner cavity is treated with high-end wear-resistant materials, effectively controlling unnecessary economic losses caused by material contamination. When the mixing chamber opens and closes, the rotor remains suspended in the middle, facilitating easy color change and material cleaning. Staff can clean every part, thanks to the all-around dead-spot-free design. It offers wide process adaptability, compact structure, and small size. The rotor speed is steplessly adjustable from 0 to 50 rpm, ensuring accuracy and stability.

Mixing Chamber of the 1L Ceramic Internal Mixer: The wear-resistant layer is prepared using plasma high-velocity oxygen-fuel (HVOF) spraying technology to apply a tungsten carbide coating. Tungsten carbide hard particles possess extremely high hardness, strength, elastic modulus, and chemical stability, playing a crucial role in resisting external friction, wear, and corrosion. The tungsten carbide coating features extremely high surface hardness and excellent wear resistance, along with high corrosion resistance, oxidation resistance, and fatigue resistance, making it widely used in engineering fields. Studies have been conducted on the wear resistance, corrosion resistance, toughness, and coating bonding strength of this coating, with comparisons made to electroplated hard chromium layers in terms of performance and actual service life.

II. Features of the 1L Ceramic Internal Mixer:

1. Equipment Concept: Uniform mixing of materials, easy color change and material cleaning, stable transmission system, precise and noiseless operation, wear and corrosion resistance. The mixing chamber uses electric heating and water cooling methods, featuring fast heating, precise temperature control, environmental friendliness, energy efficiency, low maintenance rate, high production efficiency, excellent dispersion performance, and mixing effect.

2. Cleaning Aspect: Designed with an openable mixing chamber, drawer-style opening, and gravity discharge of materials, ensuring dead-spot-free cleaning and zero residue. This offers significant advantages for expensive and contamination-sensitive materials.

3. Rotor Design: Adopts a detachable design, allowing easy disassembly, simple operation, and convenient maintenance.

4. Sealing Design: Utilizes a self-lubricating dry mechanical compression shaft seal on one end and an oil pressure compression method on the other end, ensuring effective sealing.

5. Heating Method: Employs imported segmented heating tubes embedded in the structure, with a heating power of 13 kW and a temperature of 300°C. It features high heating efficiency, stable temperature control, fast heating, and significant energy-saving advantages.

6. Compact Machine Footprint: Saves floor space with a user-friendly design.

7. Control System: Uses Siemens PLC control, programmable color touch screen, and human-machine interface. All operating parameters can be arbitrarily set and controlled, with dynamic display of the plasticizing curve. It is simple and easy to operate, high-end, and elegant, making it highly popular among customers.
