hopper, or stored in stockpiles or containers awaiting processing. All food waste would be processed within 48 hours of receipt; residual waste will be delivered to the transfer station for inclusion into outbound MSW transfer operations. Prior to grinding, the food waste is required to be free of large contaminants that could cause damage to the grinder or be deleterious to the digestion or composting process. Plastic and other contaminant material may be removed manually on the floor or on a sort line. A horizontal hammermill grinder is proposed for the use with this operation. Material is fed into the hammermill grinder. The hammers, which are attached to a rotor or shaft, impact the feed material, breaking it into smaller pieces. Below the hammer circle is a series of cast grates. The material remains inside the hammermill and is crushed or torn between the hammers and grates until its size is sufficiently reduced to pass through the grates where it is discharged onto a conveyor below. A transfer truck or container would receive the processed food waste from the equipment discharge chute. The anticipated system capacity is 20 tons per hour, but may vary depending on the materials being sorted and on any future upgrades or additions. Other mechanisms, procedures or technologies may be incorporated into the system to improve its capabilities in the future. THANK YOU, Neil S.R.
