50L High Shear Powder Mixer Machine with Oil Spraying System For Cosmetic

50L High Shear Powder Mixer Machine with Oil Spraying System For Cosmetic

Shanghai Qimeida Machinery Technology Co., Ltd. designs and builds this 50L high shear powder mixer for cosmetic powder processing. As a 50L High Shear Powder Mixer Machine with Oil Spraying System For Cosmetic manufacturer, we integrate mixing, pulverizing, homogenizing and oil spraying in one compact unit. The machine suits pressed powder, loose powder, eyeshadow, blush and powder raw material pre-processing for skincare.

Our factory in Shanghai focuses on automatic cosmetic production equipment. We supply this model to cosmetic OEM/ODM manufacturers who need repeatable batch quality, clean production and straightforward operation. The 50L working volume and 5–15 kg batch range make it a practical choice for pilot lines, small-batch production and formula development before scaling to our 100L or 200L mixers.

Machine Construction and Material Specification

The complete machine body is SUS304 stainless steel with a mirror finish. This includes the frame, hopper, lid and discharge chute. Mirror polishing reduces powder adhesion and simplifies cleaning between color changes. The double-layer hopper uses 4 mm inner and outer barrels, with a circulating cooling water jacket to control temperature rise during high-speed processing.

• Hopper capacity: 50 L; batch weight: 5–15 kg
• Machine dimensions: 1000 × 950 × 1300 mm; total weight: 320 kg
• Total power: 10 kW; power supply: 3-phase 380 V / 50 Hz
• Automatic lid open/close, automatic discharge, automatic oil spraying

Drive System and Speed Control

Two independent Siemens motors drive the main and side mixing blades. The main motor is 11 kW and the side motor is 2.2 kW, both 2-pole. A Delta VFD25AMS43ANSAA 380 V 11 kW inverter controls the main motor, and the side motor is also variable speed. Speed range is 178–2980 rpm for both axes.

This wide speed window lets you run gentle blending for fragile pigments or high-speed pulverizing for agglomerates. The main blade is a 4-blade cross design; the side blade is inclined with a 45° folded edge. Both are SUS304 and help create a strong vortex that continuously pulls powder into the high-shear zone.

Control and Automation Features

The control system uses a Delta DVP-32ES PLC and DOP-107BV touch screen. Schneider contactors and electrical components complete the cabinet. The touch screen provides visual management of motor speed, cycle timing, oil spray quantity and fault alarms. Automatic lid opening/closing and discharge reduce manual handling and improve operator safety.

The built-in oil spraying system adds oil-based ingredients during the mixing cycle. Spray timing and quantity are set from the HMI, allowing you to add binders or treatment oils without opening the lid. This is particularly useful for pressed powder formulas that need a uniform oil distribution before pressing.

Application Fit and Process Integration

This mixer is designed for cosmetic powder lines that require a clean, controlled batch process. Typical applications include:

• Pressed powder base blending before compaction
• Loose powder homogenization with mica, talc and zinc stearate
• Eyeshadow and blush pigment dispersion
• Pre-processing of powder raw materials for skincare products

Because the machine is self-contained, it can be placed near a powder pressing line or used as a standalone batch station. For higher throughput, we offer the 100L Triple-Chopper High Speed Powder Mixer Machine with Oil Spraying System and the 200L Industrial High Shear Cosmetic Powder Mixer with Triple Chopper for larger batches.

Installation, Utilities and Safety

The machine requires a 3-phase 380 V / 50 Hz supply and reliable grounding. A cooling water supply and return line must be connected to the hopper jacket. Before starting, check that the cooling circuit and oil spray system have no leaks. The protective door must remain closed during operation; the PLC interlock prevents blade rotation when the door is open.

We provide a detailed installation manual and can offer remote video guidance during commissioning. The machine is shipped as a complete unit, ready for connection to your utilities.

Quality Assurance and Acceptance Testing

Each machine is factory-tested before shipment. We run a no-load test to verify motor rotation, speed response, lid actuation and discharge function. A water test checks the cooling jacket for leaks. The oil spray system is calibrated for uniform delivery. Test results are recorded and available with the machine documentation.

Our quality control process follows the same discipline we apply to all cosmetic equipment, ensuring consistent build quality and reliable operation in your production environment.

Maintenance and Spare Parts

Routine maintenance focuses on cleaning powder contact surfaces after each batch. The mirror finish and smooth contours make this straightforward. Check the motors, inverters and electrical components periodically according to the manual. Keep spare seals for the lid and discharge valve, plus a spare set of blades if you process abrasive pigments.

We stock common spare parts for this model and can ship them quickly. Our after-sales team provides remote troubleshooting via video within 2 hours of a fault notification, helping you minimize downtime.

Related Equipment in Our Powder Line

This mixer works well with our other powder processing machines. For feeding and pressing, consider the Fully Automatic Cosmetic Powder Pressing Machine and the Automatic Down-pressing Cosmetic Powder Compact Machine with Auto Feeding. For lab-scale trials, the Laboratory High-speed Powder Grinder Machine for Cosmetics R&D helps you develop formulas before scaling to the 50L mixer.

Frequently Asked Questions

What is the actual batch capacity of the 50L mixer?

The hopper volume is 50 liters, but the recommended working batch is 5–15 kg depending on powder density. For a typical pressed powder base with bulk density around 0.5–0.7 g/cm³, a 10 kg batch fills about 20–25% of the hopper, leaving room for the high-shear vortex.

Can the oil spraying system handle viscous oils?

Yes, the system uses a pump and nozzle sized for cosmetic oils such as squalane, dimethicone or liquid binders. If your oil is highly viscous, we can add a heating jacket on the oil tank to reduce viscosity. Tell us the oil type and addition rate when requesting a quote.

How do I clean the machine between color changes?

The mirror-polished SUS304 surfaces and smooth welds make cleaning straightforward. Use a vacuum or dry wipe for powder residue, then a food-grade cleaner if needed. The hopper and blades can be accessed after the lid opens automatically. Avoid water jets on electrical components.

What is the delivery time for this machine?

Standard models are typically ready within 30–45 days after order confirmation. Custom configurations may take longer. We will provide a confirmed lead time in our quotation based on your requirements.

Do you provide installation and training support?

Yes, we offer remote video guidance for installation and commissioning. Our team can also provide on-site training if required. After-sales support includes video troubleshooting within 2 hours of a fault report.
