A multi-module system for applying a refractory monolithic onto an object includes a power module and a placement module, separated and distinct from the power module. The power module includes a hydraulic pump and a prime mover drivably coupled to the hydraulic pump. The placement module includes a mixer for receiving a dry refractory material and a liquid, the mixer operative to mix the dry refractory material and liquid to produce a wet monolithic, and a pump coupled to the mixer and configured to move the wet monolithic out of the mixer. A hydraulic conduit is couplable between the hydraulic pump and at least one of the mixer or the pump, whereby the at least one of the mixer or the pump is driven by hydraulic power produced by the hydraulic pump.

A method of operating a concrete batching plant includes loading aggregates into an aggregate storage bin divided into compartments from the ground level by wheel loader, discharging the material from storage bin through batching gates fitted into a weighing hopper, hydraulically lifting the aggregates after being weighed in the weighing hopper, conveying cement through a screw conveyor into a cement weigher and discharging the same into a mixer, mixing and compacting the aggregates for a pre-determined time, discharging the mixed and compacted concrete into a concrete carrying hopper, transporting the concrete carrying hopper to a desired height, and loading the concrete into mobile transit mixer or concrete pump, based on the site requirement.

A method for the manufacture of foamed plaster utilizing a mixture of powdered casting plaster, powdered limestone and hemp fibre. The mixture is fed into a Venturi apparatus (40) under the influence of gravity. Compressed air may be supplied to the Venturi apparatus (40) through an inlet pipe (41) causing air and solid particles to be sucked into the Venturi apparatus (40). The elongated tube is provided with an inlet nozzle arranged to receive a mixture of water mixed with detergent agents. Further, the tube (50) is provided with an inlet nozzle (56) arranged to receive compressed air such that the elongated tube (50) delivers the mixture to a mixing and spray head (60) so as to feed the resulting mixture to a moulding means.
