Green Sand Mixers
Green Sand Mixers Made for Your Foundry's Success
Engineered by our in-house manufacturing team, our green sand mixers deliver consistent performance, superior mixing uniformity, and tailored adaptability — helping foundries cut downtime, reduce costs, and boost casting quality.
About Green Sand Mixers Machine Overview
Discover the performance of our Green Sand Mixer Machine, built to deliver consistent, high-quality sand preparation for foundry operations. Engineered for precision and efficiency, this machine ensures optimal blending of return sand, new sand, bentonite, and water — producing homogenous molding sand ready for high-integrity casting.
We offer a range of significant benefits:
Mixing supports consistent sand preparation. Mixture acceptance depends on the actual recipe, incoming sand, dosing and mixing cycle.
Downtime ruins productivity. Our mixers are built with durable, wear-resistant components that keep running in even the harshest foundry conditions, minimizing breakdowns and repair interruptions.
GS batch / cyclic mixers can be integrated into a continuously operating sand line, with feeding, discharge, buffers and controls defined for the project.
Poorly optimized machines drain resources. Our energy-efficient design, smart control systems, and minimal maintenance needs help you cut costs and boost output over the long term.
As your equipment partner, we don’t just deliver machines — we deliver trust. From installation to training to after-sales support, you get fast, expert help from the people who built your machine.

Technical Specification of Green Sand Mixers Machine - Technical Specifications
GS High-Efficiency Rotor-Type Green Sand Mixer
The GS family uses batch / cyclic rotor mixing for green sand preparation. It can be integrated into a continuously operating sand preparation line; this does not make the mixer a continuous-feed machine.
As a direct manufacturer, we provide not only industrial-grade equipment, but also the technical depth and production experience to support your operations with long-term reliability and efficient integration.
Mixing Process and Acceptance
Green sand combines silica sand, bentonite clay, water and selected additives. Rotor mixing supports distribution of these components. Moisture, mold strength and mixture consistency depend on the actual recipe, incoming sand, dosing and mixing cycle; acceptance is confirmed for the project rather than guaranteed for every batch.
Technical Specifications
| Model | Nominal capacity (t/h) |

| GS29-200 | 200 | 2×55 |
Capacity conditions: Nominal throughput depends on the sand recipe, actual batch mass, mixing cycle, discharge and upstream/downstream equipment. Batch mass and cycle time require selected-model confirmation; they are not inferred from the model name or motor power.
Power and layout: Main and rotor motor ratings are separate fields, not the total installed electrical power. Auxiliary loads, total power, mixer dimensions and shaft/rotor speeds are confirmed in the selected equipment documentation before utility or layout design.
Mixing Principle and Line Integration
The GS models above are rotor-type mixers. Rotor action and the selected mixing cycle are configured for the actual green-sand process. Roller-type mixers use a different mixing principle; their model selection and specifications must be confirmed separately and are not interchangeable with this GS table.
Batch feeding, mixing and discharge are coordinated with the line buffers and controls. Continuous line operation does not imply uninterrupted feed through the mixing chamber.
