Overseas customers often get confused by specification sheets when selecting equipment. I'll break down three core indicators in plain language: power, speed, and grinding disc diameter. Power determines grinding efficiency: models below 5.5kW are suitable for small-scale jobs, 5.5-11kW for medium-sized projects, and above 11kW for heavy-duty construction. For example, I once had a European customer use a 3kW machine to grind a 2000㎡ factory floor, which took 15 days; switching to an 11kW model completed the job in just 5 days. Speed affects the smoothness of the grind: low speeds (500-1500 RPM) are ideal for coarse grinding and rust removal, medium speeds (1500-2500 RPM) for intermediate grinding and leveling, and high speeds (2500-3000 RPM) for fine grinding and polishing. Our machines feature stepless speed adjustment to meet various grinding needs. Grinding disc diameter determines the single-pass coverage area: discs under 400mm are suitable for narrow spaces, 400-600mm is a general-purpose size, and over 600mm for large-area construction. Last year, we provided a 700mm diameter grinder for a Brazilian stadium, which increased single-pass width by 16% compared to a 600mm model and overall construction efficiency by 20%. Also pay attention to the number of grinding discs: single-disc models are flexible but less efficient, while dual or triple-disc models offer higher efficiency. Our triple-disc grinder uses a triangular distribution design for seamless coverage, with 15% higher compaction than single-disc models. These parameters may seem complex, but simply tell me your grinding material, area, and precision requirements, and I can directly match you with precise, export-standard specifications.
