Abstract: The lightweight planetary UHPC mixer has a special structure, high performance, high efficiency, strong adaptability, and wide application range. With the improvement and development of China's concrete industry technology, new types of concrete materials are constantly emerging. Therefore, traditional concrete mixing equipment must adapt to the needs of new materials. The lightweight planetary UHPC mixer has emerged according to the situation, playing a certain positive role in the deep development of new building materials and new production processes. The lightweight planetary UHPC concrete mixer is portable and suitable for outdoor, indoor, floor, and different environmental operations. It is helpful for the promotion and application of current wind power engineering grouting technology, concrete 3D printing, cement centrifugal spraying well pipe lining CCCP technology, and various special polymer fiber mortar.

Introduction
At present, many concrete mixing equipment in construction projects in China still use ordinary horizontal or vertical shaft mixers. With the new round of technological revolution and industrial transformation in China, planetary concrete mixer technology has been continuously improved since its introduction from abroad and has been applied in the concrete industry, expanding its scope. It is expected to replace the traditional concrete mixing method that has been passed down to this day and will inevitably become the mainstream.
The Application Significance of Two Planetary Concrete Mixers
2.1 The difference between planetary concrete mixers and ordinary concrete mixers is that they eliminate the possibility of uneven dispersion during the mixing process. By using a combination structure of self rotation and revolution blades, 360 degree dead angle operation can be achieved, which stabilizes the material characteristics and ensures good dispersion and repeatability of the mixed material. Its special structure provides favorable conditions for uniform mixing of materials and elimination of bubbles, especially with high work efficiency and safety.
The transmission component of the planetary concrete mixer adopts a high-strength hard tooth reducer with high mechanical efficiency, which is applied to the mixing, reaction, dispersion, and dissolution of multi-component solid-phase, solid-liquid, and liquid-liquid materials. It is suitable for mixing high viscosity materials.
2.3 Planetary concrete mixer, due to its mixing track covering the entire mixing drum cavity, achieves dense and continuous mixing. It is not only suitable for the mixing of ultra-high performance concrete, aggregates, and powder materials, but also for the mixing of various types of special polymer fiber mortar, including self leveling mortar, anti-corrosion, crack resistance, fire prevention, waterproofing, insulation, reinforcement, etc. It is used for the manufacturing and production of materials and products such as PC components, bricks and tiles, water glass, ceramics, ceramic particles, refractory, welding, etc.
Characteristics of 3 Light Planetary UHPC Concrete Mixers
3.1. Currently, the existing planetary concrete mixers are generally fixed and cannot be moved, making it difficult to relocate. Even if migration requires dismantling into numerous components, reinstallation requires a large amount of labor, and transportation is difficult and costly. In addition, it is inevitable that there will be dripping of remaining mixture at the material outlet, resulting in material waste.
3.2 At present, the planetary mixer body on the market is heavy and bulky, generally used for large and medium-sized non mobile fixed commodity concrete mixing plants, and must face construction projects with a certain scale and a large demand for concrete. Moreover, continuous operation is required, otherwise frequent shutdowns not only result in waste of remaining materials, but also require manual cleaning of equipment and loss of water resources.
3.3. The lightweight planetary UHPC mixer manufactured by Wenzhou Wengong Engineering Machinery Co., Ltd. is developed for the concrete industry to address the contradiction of existing technology. Since its launch in the market, it has been highly favored and praised by users due to its outstanding practicality and product cost-effectiveness.
Light planetary UHPC mixers are divided into mobile single planetary mixers, mobile double planetary mixers, and mobile triple planetary mixers based on the mixing material capacity, all of which have unique and innovative mixing performance. Its structure is composed of planetary stirring components arranged inside the mixing drum made of high-strength wear-resistant materials, with stirring arms rotating around the central axis of the mixing drum at different angles and orientations, and rotating at different speeds in stages around its own axis for both high-speed rotation and rotation around the central axis of the mixing drum. Due to the complex and intersecting trajectory of the mixed materials, multi-dimensional strong radial flow, axial flow, and moving cross circulation eddy currents are generated, causing strong shear and kneading of the materials. The contact surface of the mixed components is large, and the size of the slurry micro clusters is reduced. Through effective mixing, the materials are stirred thoroughly, evenly, and quickly in the shortest possible time.
3.4 The lightweight planetary UHPC mixer is suitable for mixing high viscosity and high solid materials. It can solve any type of mixing material that requires sufficient and fast mixing that other mixing equipment cannot overcome. Moreover, there are no limitations on the types of materials to be mixed. Capable of obtaining low-cost mixing materials with high quality and high requirements in various fields.
The lightweight planetary UHPC mixer is equipped with an intelligent metering water supply system, an electrically controlled discharge door, and a movable and fixed wheel group. The entire machine can be placed and used nearby at any construction site, or a fixed mixing plant can be set up in the workshop for use.
3.5. The lightweight planetary UHPC mixer is equipped with different mixing capacities of 200-1000L to adapt to the expansion of its usage range. Currently, it involves off-site operations in building construction, road and bridge engineering, tunnel engineering, underground pipe gallery, and landscape engineering, as well as indoor leveling, floor level, and indoor mobile use. With the development of ultra-high performance concrete technology, the requirement for lightweight, high-efficiency, and low-cost mixing equipment is becoming increasingly prominent. Therefore, the lightweight planetary UHPC mixer plays an indispensable role and position in the application of high viscosity polymer fiber mortar with many advantages.
4 Conclusion
The application of "thermal engineering" lightweight planetary UHPC concrete mixer technology provides favorable conditions for promoting the improvement of the concrete industry, and its role cannot be ignored in the current market of new concrete materials and products. The widespread application of concrete 3D printing technology and centrifugal spraying underground well pipe lining CCCP technology today, as well as the rapid development of PC component production, self leveling mortar, anchoring mortar, and polymer mortar varieties, will inevitably promote and promote the technology and application of lightweight planetary UHPC concrete mixers to take a leap forward.
