The plant consists of:

Loading Hopper with steep sides and lining material to recieve the aggregate or soil from loading shovel bucket.

A belt feeder is mounted on the outlet of the hopper.

Twin Shaft Pugmill mixer

Twinshaft continuous pugmill mixer to mix the aggregate and cement material.

Chill Cast Steel Mixing Paddles mix the material whilst propelling it along the mixing chamber. Large opening covers on side and top of mixer give maximum maintenance access.

A belt conveyor forms the base of the mixing chamber simplifying the cleaning operation.

Cement Silo
