Do You Need A Counter Current Concrete Mixer
Jul 15, 2025
In the field of building materials production, the performance of concrete mixers directly affects the quality and production efficiency of concrete. As an innovative mixing equipment, planetary concrete mixers are gradually emerging in the industry with their unique working principle and significant advantages, and have become an ideal choice for many projects with high requirements for concrete quality.
1. Working principle
The core design of a counter current mixer lies in the movement of its mixing arm. Unlike traditional mixers, its mixing arm does not rotate around the central axis alone, but simultaneously revolves and rotates, just like a planet revolving around a star while rotating itself, hence the name "planetary mixer".
This composite motion mode makes the motion trajectory of the material in the mixing drum extremely complex. During the revolution, the mixing arm drives the material to make circular motion in the mixing drum to achieve large-scale mixing of the material; during the rotation, the rotation of the mixing arm itself strongly shears and kneads the surrounding material.
Under the combined action of these two movements, the material forms strong convection, shearing and extrusion in the mixing drum, thereby achieving a highly uniform mixing state in a short time.
2. Applicable concrete types
Ultra-high performance concrete (UHPC): UHPC has extremely high requirements for the uniformity of raw material mixing, and ordinary mixers are difficult to meet its stringent standards. With its unique mixing method, planetary concrete mixers can evenly disperse multiple components such as cement, mineral admixtures, aggregates, and fibers, ensuring that the high strength and high durability of UHPC can be fully utilized, effectively solving the problems of fiber agglomeration and uneven material distribution that are prone to occur when ordinary mixers mix UHPC.
Fiber-reinforced concrete: Whether it is steel fiber, synthetic fiber or glass fiber, it is crucial to distribute it evenly in concrete, otherwise it will seriously affect the mechanical properties of concrete. The complex mixing trajectory of the planetary mixer can effectively break up the fiber clusters and make them evenly distributed in the concrete matrix, significantly enhancing the toughness and crack resistance of the concrete, which is difficult for ordinary mixers to achieve.
Hard and semi-hard concrete: This type of concrete has low water content and poor fluidity, so ordinary mixers are prone to inadequate mixing and material agglomeration during mixing. The powerful mixing force of the planetary mixer can efficiently mix hard and semi-hard concrete, so that its components are fully mixed to ensure the working performance and strength of the concrete.
3. Common models
Small model (such as JN500): rated discharging capacity of 0.5 cubic meters each time. It is commonly used in small and medium-sized construction projects, such as small residential construction, road repair projects, etc.
Medium-sized models (such as JN1000): It is a medium-sized mixer with a large mixing volume. It is widely used in large and medium-sized building materials production lines, refractory production lines, permeable brick production lines, and ceramic production lines.
Large models (such as JN2000): can discharge up to 2 cubic meters at a time, often used as the main machine configuration of various cement and concrete prefabricated component production lines, and is the mainstream choice of mixing main machine for PC production lines.
Although the initial purchase cost of a planetary concrete mixer may be slightly higher than that of an ordinary mixer, its advantages are obvious in terms of long-term operating costs. High mixing efficiency reduces production time costs; excellent mixing effect reduces rework costs caused by concrete quality problems.
At the same time, the equipment has a reasonable structural design, stable operation, relatively simple maintenance, low failure rate, and reduces equipment maintenance costs. Overall, it has a high cost-effectiveness. Welcome to inquire planetary concrete mixer price from us directly.
