The Chapin 8500B 200 - Pound Stainless Steel Professional Rock Salt Drop Spreader is specifically designed to distribute larger particulates like rock salt and ice melt.
The spreader's design is optimized for materials with a variable size and larger particles so while this spreader can be used for some types of pellets, it would not be recommended for small, uniform pellets like fertilizer, grass seed, or certain types of lime.
Per Chapin, thoroughly clean the unit right after each use to ensure no chemical residue is left over from any product to negatively impact the next application you may make.
