摘要:
Equipment for heating pulverulent products, including a relatively flat, vertically standing vessel for receiving the product, and a rotatable agitator whose axis of rotation is coincident with the longitudinal axis of the vessel. There are heating facilities in the bottom of the vessel. With these heating facilities, the bottom and side wall of the vessel are heated. The top of the vessel is insulated. The product is introduced into the vessel through the top and discharged in the region of the bottom of the vessel.

摘要:
A mobile concrete mixing unit has an aggregate bin divided into two compartments by a water tank provided within the aggregate bin. A hydraulic reservoir is provided within the water tank in order to cool the hydraulic fluid within the hydraulic reservoir and warm the water within the water tank. The water tank also helps to keep the aggregate warm and flowable when used in low temperatures. A lower portion of the water tank includes sides that slope inwardly so that aggregate within the bin can drop freely onto a conveyor belt without bridging between the water tank and the sidewalls of the aggregate bin.

Portable metering and mixing apparatus includes a trailer having a hopper thereon divided into two compartments, one compartment for sand material and another compartment for cementitious material. Screw conveyor assemblies, or auger assemblies, receive the materials and convey the materials to a mixer assembly. Different embodiments are disclosed. One embodiment includes a mixing chamber aligned with an auger assembly and to which the mixing chamber materials are fed directly. Another embodiment discloses a separate mixer assembly to which the materials are conveyed by a pair of auger assemblies.
