A plant to produce concrete by mixing sand, cement, aggregate and water by a continuous operation. A plurality of storage hoppers with twin outlets associated with weigh hoppers permit a discharge of aggregate and sand material through vibratory feeders onto a conveyor belt so that one group of weigh hoppers discharges while a second group is being filled. The conveyor belt delivers in a continuous manner to a trough mixer which receives cement from a silo and water for mixing said ingredients. |
