Impact on grinding quality (general) |
|---|---|---|---|---|
|
MS |
Mild Steel |
Yes (can rust if moisture/contact with water) |
Not ideal for direct food contact unless properly coated/painted and maintained |
Can add rust risk + contamination if coating wears. Better to use SS for contact parts. |
|
Aluminium |
Aluminium |
No rust, but can oxidize/mark with some materials |
OK for some uses, but not preferred for spices/food contact in heavy grinding |
Can react/blacken with some acidic/salty materials; not the best for long-term spice grinding contact parts. |
|
CI |
Cast Iron |
Yes (can rust; needs care) |
Used in some grinding applications, but needs good maintenance |
Strong and heavy. If rust forms, it can affect product cleanliness. Needs dry storage + care. |
|

Very high rust resistance |
Highly recommended for food contact |
Best balance for hygiene + durability. Helps keep powder clean. |
|
SS316 |
Stainless Steel 316 |
Highest rust/corrosion resistance |
Best for food contact (premium) |
Best for long life, especially if moisture/salt exposure is higher. Premium hygienic option. |
