GRC250S Combination Mixer System
The GRC250S Combination Mixer from Power-Sprays is a high-capacity, high-shear solution for both premix and spray-based GRC production. With a 250 kg batch capability, powerful 15 kW variable-speed motor, and pneumatic discharge system, it ensures rapid mixing, easy maintenance, and consistent fibre dispersion—perfect for large-scale manufacturing.
Description
The Power-Sprays GRC250S Combination Mixer expands Power-Sprays’ specialist mixer range for Glassfibre Reinforced Concrete (GRC). Building on the success of the smaller GRC125S, this high-capacity mixer easily handles batches of Premix GRC up to 250 kg (550 lbs). Equipped with a powerful 15 kW variable-speed motor, the GRC250S effectively produces both slurry for hand-spray GRC and robust Premix GRC, making it an ideal solution for demanding production environments that value efficiency, consistency, and ease of maintenance.
