Q1: Can this mixer handle materials with vastly different densities like TiO2 and LDPE powder?
A: Absolutely. This 300L Horizontal Ribbon Blender is specifically engineered for the Plastic Masterbatch industry. The double-layer ribbon agitator creates a powerful "convective mixing" action. It effectively lifts heavy powders like Titanium Dioxide (TiO2) and Calcium Carbonate while drawing lighter LDPE powders into the mix, ensuring a homogeneous blend without segregation.
Q2: Why is the working volume (180L) different from the total volume (300L)?
A: To ensure optimal mixing efficiency and prevent material overflow, ribbon blenders should not be filled to the brim. The Total Volume is 300 Liters, but the recommended Effective Working Volume is 180 Liters (approx. 60% load factor). This leaves enough headspace for the particles to move freely and mix thoroughly, guaranteeing the best product quality.
Q3: How do you prevent the LDPE powder from melting during mixing?
A: We understand that LDPE is heat-sensitive. This machine is equipped with a Variable Frequency Drive (VFD) that controls the 7.5kW Siemens Motor. You can adjust the mixing speed (0-46 RPM) to find the perfect balance—fast enough for efficiency, but gentle enough to minimize friction heat, protecting your resin from degradation.
Q4: Is this machine easy to clean for color changes?
A: Yes, minimizing cross-contamination is critical for Masterbatch. The interior is made of Stainless Steel 304 with a high-grade Mirror Polish finish. This smooth surface prevents powder from sticking to the walls. Combined with the Pneumatic Butterfly Valve for complete discharge, it significantly reduces cleaning time between different color batches.
Q5: What safety features does the machine have for UK/EU compliance?
A: Safety is our top priority. The mixer features a Safety Grid Interlock System. If the top lid is opened or not correctly positioned, the machine will automatically stop (or fail to start). This design fully complies with strict UK and European Health & Safety regulations regarding rotating machinery.
Q6: I am in the UK. Will I have trouble finding spare parts?
A: Not at all. We use world-renowned brands for all critical components: Siemens Beide for the motor, Schneider for electrical components, and NSK for bearings. These are global standard parts, meaning you can easily find replacements locally in the UK or anywhere in Europe, ensuring minimal downtime.
Q7: Does the voltage match UK standards?
A: Yes. We customize the electrical system to match your local power supply (e.g., 415V, 50Hz, 3-Phase for the UK). The control panel is professionally wired and labeled, ready for plug-and-play installation by your electrician.
