100L Triple-Chopper High Speed Powder Mixer Machine with Oil Spraying System

100L Triple-Chopper High Speed Powder Mixer Machine with Oil Spraying System

Shanghai Qimeida Machinery Technology Co., Ltd. designs and builds this 100L triple-chopper high speed powder mixer for cosmetic powder batch processing. As a 100L Triple-Chopper High Speed Powder Mixer Machine with Oil Spraying System manufacturer, we integrate mixing, pulverizing, homogenizing, and oil addition into one automated cycle. The machine suits pressed powder, loose powder, eyeshadow, blush, and similar dry or slightly oil-bound cosmetic formulas.

We supply this unit to cosmetic OEM/ODM plants that need repeatable batch quality, reduced manual handling, and a stainless steel process path. The mixer is built around a 100L double-layer hopper, a Siemens main drive, three independent side choppers, and a Delta PLC control platform. Our engineers configure the cycle parameters, oil spray timing, and discharge logic to match your specific powder recipe and production target.

Machine Construction and Material Specification

The complete machine body is SUS304 stainless steel with a mirror finish, including the hopper, lid, blades, and material-contact surfaces. The double-layer hopper uses 4mm thickness for both inner and outer barrels, with a circulating cooling water jacket between them. This design controls temperature rise during high-speed chopping, which is critical for heat-sensitive cosmetic powders containing oils, waxes, or active ingredients.

The main mixing blade is a one-piece SUS304 4-blade cross design. The three side blades are inclined thick blades with a 45° folded edge, also in SUS304. These blades create a multi-dimensional shear field that breaks agglomerates and distributes minor components evenly. The mirror finish reduces powder adhesion and simplifies cleaning between color changes.

Drive System and Speed Control

The mixer uses a Siemens 2P 18.5kW main motor and three Siemens 2P 2.2kW side motors. Each motor is paired with a Delta VFD inverter (main: VFD38AMS43ANSAA 380V 18.5kW; side: VFD17AMS43ANSAA 380V 7.5kW). The inverters allow variable speed adjustment from 178rpm to 2980rpm, giving you the flexibility to run gentle blending cycles for fragile powders or high-energy pulverizing cycles for hard agglomerates.

Speed profiles are programmable through the Delta DVP-32ES PLC and DOP-107BV touch screen. You can store multiple recipes with different speed ramps, mixing times, and oil spray sequences. This is particularly useful when you produce several SKUs on the same line.

Automation and Integrated Systems

This model is designed for semi-automated batch operation. The lid opens and closes automatically, locks during the mixing cycle, and the hopper tilts for automatic discharge. These functions reduce operator fatigue and speed up batch turnover.

The built-in automatic oil spraying system injects oil-based ingredients (e.g., mineral oil, esters, or liquid preservatives) into the powder bed while the choppers are running. Spray timing and flow are controlled by the PLC, ensuring uniform oil distribution without over-wetting. The circulating cooling water system maintains a stable hopper temperature, which helps prevent oil oxidation and powder caking.

Electrical and Control Components

All electrical components in the cabinet are Schneider brand, including contactors and protective devices. The main motor, side motors, and inverters are Siemens and Delta, respectively. This combination provides reliable operation in industrial environments and simplifies spare parts sourcing.

The touch screen interface displays real-time motor speed, cycle time, temperature (if sensors are fitted), and alarm messages. Operators can start, stop, and monitor the machine from the panel. The PLC also supports basic data logging for batch traceability.

Technical Specifications

Application Fit and Process Considerations

This mixer is intended for dry powder blending and pulverizing, with the option to add small amounts of liquid oil (typically 1-5% of batch weight). It is not designed for wet granulation or high-moisture slurries. For those applications, consider our 100L Horizontal Trough Mixer Machine for Cosmetic Wet Powder.

Typical products include:

• Pressed powder foundations and blushes
• Loose powders and finishing powders
• Eyeshadow and pigment blends
• Mineral makeup bases

For higher throughput, we offer the 200L Industrial High Shear Cosmetic Powder Mixer with Triple Chopper. For smaller R&D batches, the 50L High Shear Powder Mixer Machine with Oil Spraying System is available.

Installation, Utilities, and Safety

The machine requires a 3-phase 380V/50Hz power supply with reliable grounding. A water supply and drain connection is needed for the cooling water circulation. We recommend a water temperature below 25°C for optimal cooling efficiency. The unit is delivered as a complete assembly; installation involves positioning, leveling, connecting power and water, and verifying safety interlocks.

Safety features include an interlocked protective door that prevents operation when open, and automatic lid locking during the mixing cycle. Operators must not open the door or touch moving parts while the machine is running. We provide a detailed operation manual and safety labels on the machine.

Quality Assurance and Testing

Each mixer undergoes a factory test before shipment. We verify motor rotation, inverter parameters, PLC program logic, lid and discharge mechanisms, oil spray function, and cooling water circulation. The machine is run with a representative powder load to confirm mixing uniformity and discharge completeness. We document the test results and provide them with the shipment.

Our manufacturing process follows internal quality control procedures. We use calibrated instruments and inspect all welds, surface finishes, and electrical connections. The machine is cleaned and dried before packing to prevent contamination.

Maintenance and Service Support

Routine maintenance includes cleaning the hopper, blades, and material-contact parts after each use to avoid powder residue buildup. Check the cooling water system and oil spray nozzles for leaks before starting. Periodically inspect motor bearings, V-belt tension (if applicable), and electrical connections. The PLC and inverter parameters are stored in non-volatile memory; we provide backup instructions in the manual.

We offer remote troubleshooting via video call within 2 hours of a fault notification. Our after-sales team can guide your technicians through diagnostics and repairs. Spare parts such as blades, seals, and sensors are available from our Shanghai factory.

Information We Use to Configure Your Solution

To prepare an accurate quotation and configuration, we need the following details from your side:

• Powder type and bulk density (g/L)
• Batch size per cycle (kg) and required cycles per hour
• Oil type and percentage to be sprayed
• Target particle size or mixing uniformity
• Available power supply (voltage/frequency)
• Cooling water temperature and flow rate
• Any specific PLC or HMI language requirements

With this information, we can recommend the correct blade configuration, speed profile, oil nozzle type, and cycle time. We also provide layout drawings and installation guidance.

Frequently Asked Questions

Q: What is the actual batch capacity of the 100L mixer?

A: The hopper volume is 100 liters, but the recommended working batch is 10-25kg per cycle, depending on powder density. For a typical pressed powder base with bulk density around 0.5 g/cm³, a 20kg batch fills about 40 liters, leaving room for efficient mixing and chopping.

Q: Can the oil spraying system handle viscous oils or waxes?

A: The system is designed for low-to-medium viscosity oils that can be atomized at ambient temperature. If you need to spray heated oils or waxes, we can add a heated tank and insulated lines. Please specify your oil viscosity and temperature requirements.

Q: How long does a typical mixing cycle take?

A: Cycle time depends on the formula and desired homogeneity. For most cosmetic powders, a cycle of 5-15 minutes is sufficient, including oil spraying and discharge. We can program a recipe that matches your target cycle time.

Q: Is the machine CE certified?

A: We can provide CE certification documentation if required for your market. Our machines are built to meet applicable EU safety directives. Please confirm your certification needs when requesting a quotation.

Q: What is the lead time for this mixer?

A: Standard lead time is approximately 30-45 days after order confirmation, depending on production schedule and customization level. We will provide a confirmed delivery date in our quotation.
