Planetary Countercurrent Intensive Concrete Mixer
Key Features
1.High-Intensity Countercurrent Mixing Technology
The LNK7 Planetary Countercurrent Concrete Mixers is a premium Counter Current Intensive Mixer that employs dual-axis planetary motion combined with counter-flow action, ensuring complete and uniform dispersion of materials. This makes it ideal for processing high-density and high-viscosity materials.
2.Robust Planetary Mixing Mechanism
Unlike conventional mixers, Planetary Countercurrent Concrete Mixers like the LNK7 use a synchronized motion where the mixing tools rotate on their own axis while orbiting the central axis, resulting in thorough material turnover with no dead zones.
3.Heavy-Duty Industrial Performance
Engineered for continuous, heavy-load operation, this Planetary concrete mixer excels in demanding applications such as mineral processing, refractory material mixing, and solid waste handling, maintaining long-term stability and consistency.
4.Flexible Speed Control and Shear Customization
The LNK7 Planetary concrete mixer features multiple inverter-controlled drives that independently regulate vessel rotation, ploughshare mixing, and high-shear mixing speeds. This flexibility enhances the adaptability of the Planetary Countercurrent Intensive Mixer to a variety of material characteristics.
5.High-Capacity Mixing Vessel
With a mixing volume reaching industrial-scale levels, the LNK7 Planetary Countercurrent Concrete Mixer can process large batches efficiently, improving overall productivity in centralized production lines.
6.Smart Operation & Easy Maintenance
Integrated with automated monitoring systems, the Planetary concrete mixer offers real-time diagnostics, remote control capabilities, and quick access maintenance ports—minimizing downtime and labor requirements.
7.Environmentally Friendly and Efficient
As a modern Counter Current Intensive Mixer, the LNK7 supports green manufacturing by reducing energy consumption and minimizing material waste during mixing, aligning with sustainable industrial goals.

Yes, we provide comprehensive installation and commissioning support, either on-site or through remote technical assistance, to ensure optimal equipment performance.
The standard warranty period for most core equipment is generally 12 months, with exact terms defined in the purchase agreement.
First, customers should provide information on the type and hardness of local raw materials (e.g., granite, river pebbles, limestone etc.). Next, customers need to specify the desired finished product requirements, including fineness modulus and particle shape. Then, based on the required production capacity (e.g., tons per hour), different models can be recommended—for example, a shaping sand making machine for higher output, or equipment tailored for ordinary or specialized mortar production depending on the application. Finally, customers can select and customize the equipment based on site conditions, installation environment, energy consumption, maintenance costs, and overall project budget.
Our equipment complies with international standards, including ISO 9001 quality management certification,ISO 14001 – Environmental Management System. Third-party inspections, such as SGS reports, can be arranged based on specific customer requirements.
We accept multiple payment methods, including T/T, L/C, and others as agreed upon in the contract. The Incoterms accepted are generally FOB,CFR,CIF,DAP,and also depending on the terms specified in the contract.
