250kg per Batch Single Shaft Double Screw Mixer - High Efficiency & Uniform Mixing Solution

Are you looking for a reliable, efficient mixing machine that delivers consistent results for batches up to 250kg? Our Single Shaft Double Screw Mixer is engineered to meet the demands of small to medium-sized production lines, combining robust construction, user-friendly operation, and exceptional mixing performance. Whether you’re in the feed, food, chemical, or building materials industry, this mixer is designed to streamline your mixing process, reduce labor costs, and ensure uniform blending every time.

How It Works: Advanced Mixing Mechanism

The 250kg per batch single shaft double screw mixer operates on a precision-engineered principle that ensures thorough, fast, and uniform mixing of various materials. Composed of a horizontal barrel, a single main shaft, and two counter-rotating spiral blades (double screws), the mixer leverages the synergy of convection, shear, and turnover to achieve optimal blending results.
When in operation, the motor drives the main shaft to rotate through a reducer, and the two spiral blades with opposite rotation directions work simultaneously. The inner spiral blade pushes materials along the inner circle to one end, while the outer spiral blade pushes materials along the outer circle to the opposite end. This creates a continuous circular flow of materials inside the barrel, making the materials collide, interpenetrate, and shear with each other repeatedly. Within 3-6 minutes per batch, even trace additives can be uniformly mixed with the main materials, ensuring the consistency and quality of the final product. Additionally, the mixer is equipped with a liquid adding system, allowing for the uniform spraying of oils, additives, or other liquids during the mixing process to enhance product nutrition or performance.

Wide Range of Applications

Our 250kg per batch single shaft double screw mixer is highly versatile and suitable for mixing dry powders, granules, and even light pastes across multiple industries. Its flexible design makes it an ideal choice for:
  • Feed Industry: Mixing corn, wheat, oats, bean meal, bran, trace elements, and oils to produce premixes, complete feeds, and concentrated feeds for pigs, cattle, sheep, chickens, ducks, geese, and rabbits. Perfect for small to medium-sized farms, feed factories, and breeding cooperatives.
  • Food Industry: Blending flour, starch, spices, dried fruits, and other food raw materials, suitable for bakeries, snack factories, and food processing plants. The stainless steel version meets food hygiene standards, ensuring safe production.
  • Chemical Industry: Mixing chemical powders, pigments, additives, and fillers, such as cement, lime powder, fly ash, and plastic particles, widely used in chemical processing, building materials, and plastic production.
  • Other Industries: Also applicable to the mixing of fertilizers, pharmaceutical raw materials, and decorative materials, providing a one-stop mixing solution for various production needs.

Core Advantages: Why Choose Our Mixer?

Compared with traditional mixers, our 250kg per batch single shaft double screw mixer has obvious advantages in efficiency, mixing quality, and usability, helping you gain an edge in production:
  1. High Mixing Uniformity: Adopting double spiral blade design, the mixer eliminates mixing dead corners, with a mixing uniformity of ≥93% and a coefficient of variation (CV) of less than 10%, ensuring that each batch of materials has consistent quality. Even trace additives (as low as 0.1%) can be fully mixed.
  2. Fast Mixing Speed: Each batch of 250kg materials can be mixed thoroughly in 3-6 minutes, which is 30% faster than traditional mixers, greatly improving production efficiency and reducing production cycle.
  3. Durable & Stable Performance: The barrel and spiral blades are made of high-quality carbon steel or stainless steel (optional), with wear-resistant surface treatment, ensuring long-term stable operation under heavy load. The belt drive design ensures stable operation, low noise (less than 90dB), and overload protection to avoid damage to components.
  4. Easy Operation & Maintenance: Equipped with a simple and intuitive control panel, one person can complete the operation of feeding, mixing, and discharging. The bottom large door design enables quick and thorough discharging, with minimal material residue and no leakage. Regular maintenance only requires cleaning and lubrication, reducing maintenance costs and downtime.
  5. Flexible & Customizable: The mixer supports customization of barrel material (carbon steel/stainless steel), motor power, and discharge direction (left/right optional) according to your specific production needs. It can also be equipped with a PLC control system for automatic operation, further reducing labor intensity.
  6. Energy-Saving & Cost-Effective: Equipped with a national standard pure copper motor, it has high power efficiency, low energy consumption, and long service life, effectively reducing your long-term operating costs. The compact structure saves workshop space, making it suitable for small and medium-sized production sites.

Frequently Asked Questions (FAQ)

We’ve compiled the most common questions our customers ask about the 250kg per batch single shaft double screw mixer to help you make an informed decision:
  1. Q: What types of materials can this mixer handle? A: It is suitable for mixing dry powders, granules, and light pastes, such as feed raw materials, food ingredients, chemical powders, fertilizers, and building materials. It is not suitable for high-viscosity pastes or materials with large hard particles (to avoid damaging the blades).
  2. Q: How long does it take to mix one batch of 250kg materials? A: The standard mixing time is 3-6 minutes per batch. The actual time may vary slightly according to the type, humidity, and mixing requirements of the materials, but it will not exceed 8 minutes.
  3. Q: Is the mixer easy to clean? A: Yes. The barrel has a smooth inner wall, and the bottom large door design allows for thorough cleaning after each use. For food or pharmaceutical applications, we recommend choosing the stainless steel version, which is easier to clean and meets hygiene standards.
  4. Q: Can I customize the mixer according to my needs? A: Absolutely. We support customization of barrel material (carbon steel/stainless steel), motor power, overall dimensions, discharge direction, control system (manual/PLC automatic), and liquid adding system to meet your specific production requirements.
  5. Q: What is the warranty period, and how to get after-sales service? A: The warranty period is 12-24 months for core components (motor, reducer, etc.). We provide 24/7 online technical support, and if there is a quality problem within the warranty period, we will send replacement parts for free or arrange on-site maintenance (depending on the situation).
  6. Q: How to install the mixer? A: The mixer is delivered with a detailed installation manual. It requires simple fixing on a flat ground, connection of the power supply, and adjustment of the main shaft rotation direction. We can also provide online installation guidance or arrange on-site installation services for an additional fee.
  7. Q: What is the power consumption per hour? A: The power consumption depends on the motor power. For a 2.2KW motor, the hourly power consumption is about 2-2.2 degrees; for a 7.5KW motor, it is about 7-7.5 degrees. The actual power consumption will be slightly lower under normal operation.
  8. Q: Can the mixer be used for continuous production? A: This mixer is a batch-type mixer, which is more suitable for batch production. If you need continuous mixing, we can provide customized continuous-type single shaft double screw mixers according to your production capacity.
