For contractors in Indiana seeking efficient concrete surface preparation, diamond grinding equipment rentals offer a cost-effective solution. Key machines include walk-behind grinders (e.g., 20–30 HP models with 12″–24″ grinding widths) and ride-on units for large-scale projects (up to 60 HP, 36″ width). These grinders utilize segmented diamond blades (grit range: 30–400) to level surfaces or remove coatings at depths of 1/8″–1/4″ per pass.
Processed concrete waste from grinding can be fed into mobile crushing plants (e.g., jaw crushers like J50v2 with 255 HP, throughput up to 300 TPH) and cone crushers (C38R with 350 HP). Secondary screening via vibratory screens (e.g., S130 triple-deck, output: 500 TPH) separates aggregates into reusable sizes:
– 0–5mm: Fine sand for mortar
– 5–20mm: Concrete mix aggregate
– 20–40mm: Road base material

Q: What’s the rental cost for diamond grinders in Indiana?
A: Rates vary from $150–$500/day depending on machine size and duration.
Q: Can recycled concrete aggregate replace natural gravel?
A: Yes, when processed to ASTM C33 standards (<3% impurities).
A project in Indianapolis utilized a LT106 jaw crusher paired with a diamond grinder rental to recycle 10,000 sq ft of demolished concrete into Class B road base, achieving 95% material reuse.
