Contaminated material is unwanted content in the feedstock material. Using feedstock with contaminates means a lower quality finished product containing contaminated materials. This unwanted content may including rocks, dirt, tramp metal, and plastic. All of these materials can cause problems with the finished material, such as plastic in compost.
Waste wood such as railroad ties and pallets often have unwanted metal and nails.
Contaminates may also cause additional wear to grinder machine parts.
The Scrap Metal Chute is the large steel pan that hangs beneath the discharge belt. The magnetic head pulley at the top of the discharge belt holds tramp metal to the conveyor as it returns the loop. The metal releases from the belt once it’s pass the head pulley and drops onto the scrap metal chute. This helps keep metal out of the stockpile. Putting a bin below to collect metal materials will keep it separate.
