Against the backdrop of the surge in demand for building industrialization and green building materials, an efficient and precise planetary concrete mixer is quietly changing the production pattern of GRC (glass fiber reinforced cement) lightweight hollow wall panels. With its excellent mixing uniformity, material adaptability and production efficiency, the equipment is helping wall panel manufacturers break through quality bottlenecks and meet the market’s stringent requirements for high-performance, lightweight prefabricated components.
Industry pain points: Traditional mixing processes restrict the quality improvement of GRC wall panels
GRC lightweight hollow wall panels are increasingly widely used in high-rise buildings, prefabricated buildings and indoor partitions due to their outstanding advantages such as light weight, high strength, fireproofing and sound insulation, and flexible design. However, its core production link – uniformly mixing cement, fine aggregate, lightweight filler (such as EPS particles), admixtures and key glass fibers – has long faced challenges:
Uniformity problem: Uneven fiber dispersion can easily lead to strength fluctuations and cracking of the board surface.
Material damage: Traditional strong mixing can easily destroy fiber integrity and lightweight aggregate structure, affecting the final performance.
Efficiency bottleneck: Complex material systems require longer mixing cycles, which restricts capacity improvement.
Insufficient stability: Quality differences between batches affect the reliability and engineering application of wallboards.
: Accurate solution to enable high-quality wallboard manufacturing
In response to the above pain points, planetary concrete mixers provide a systematic solution for the production of GRC lightweight wallboards with their unique “planetary motion” principle (the mixing arm rotates at high speed while revolving around the main axis):
Uniform mixing without dead ends: Multi-directional composite motion ensures that cement paste, fine aggregate, lightweight filler and chopped glass fiber are extremely evenly distributed in three-dimensional space in a short time, eliminating agglomeration and significantly improving the consistency of mechanical properties of wallboards.
Gentle and efficient, protecting fibers and lightweight aggregates: Compared with traditional twin-shaft or vortex mixing, the gentle and efficient mixing action of planetary concrete mixing greatly reduces shear damage to glass fibers and damage to the structure of lightweight aggregates (such as EPS beads), ensuring the inherent properties of the material.
High efficiency and energy saving: The optimized mixing path and strong power shorten the time to achieve the required homogeneity by 30%-50%, significantly improving the efficiency of the production line and reducing unit energy consumption.
High adaptability: The speed, time and other parameters can be flexibly adjusted to perfectly match the different ratio requirements from high-flow grouting materials to viscous GRC mortar, especially good at handling low water-cement ratio and high fiber content mixtures commonly used in lightweight wall panels.
Intelligent control: Modern planetary concrete mixers integrate PLC control systems to accurately control the feeding sequence, mixing time and speed, ensuring high stability between batches and safeguarding the quality of wall panels.
Application results: Customers witness the leap in quality
“After the CO-NELE planetary concrete mixer was used in the GRC hollow wall panel production line, the product quality has undergone a qualitative leap, the apparent density of the wall panels has been improved, the fiber exposure and surface pores have been eliminated, the bending strength and impact resistance have increased by more than 15% on average, and the customer complaint rate has dropped significantly. At the same time, the single-shift production capacity has increased by about 40%, and the comprehensive benefits are very significant.”
