One of the most common mistakes atta shop owners make is buying the wrong machine size. A machine that is too small leaves customers waiting. One that is too large increases cost and electricity waste. Here is how to choose correctly.
Step 1 — Estimate Your Daily Customer Count
Count or estimate how many customers you expect per day. Each customer typically brings 2–10 kg of grain. This is your daily throughput requirement.
- 5–20 customers/day → 10-inch or 12-inch machine
- 20–40 customers/day → 14-inch Poonamdeep
- 40–80 customers/day → 14-inch or 16-inch
- 80–150 customers/day → 16-inch commercial
- 150+ customers/day → 18-inch industrial
Step 2 — Check Your Power Supply
This is non-negotiable. 10-inch and 12-inch machines run on single-phase (home supply). 14-inch and above REQUIRE three-phase (commercial connection). If your location only has single-phase, you are limited to 12-inch maximum.
Step 3 — Choose Your Stone Type
Diamond Stone (Kapi Poonamdeep) costs more upfront but saves ₹8,000–₹20,000/year in maintenance. For any commercial installation that runs 6+ hours/day, diamond stone pays for itself in the first year.
Step 4 — Set Your Budget Correctly
Do not just look at machine price. Calculate Total Cost of Ownership over 3 years:
- Machine cost
- Motor cost
- Installation cost (once)
- Electricity (monthly × 36)
- Maintenance: for emery stone — ₹1,000–₹1,500/month × 36. For Diamond Stone — ₹0
When you calculate it this way, Diamond Stone machines consistently win on total cost.
