Obviously, it can be seen that when this consumption is- camelwaybined with storm water run-off, sprayed water and conveyor water washdowns, significantly large quantities of waste water are generated at a typical ready-mix plant in any given working day. Also, a typical ready-mix plant may produce 500 m3 of concrete per day.

Water Chilling Plants. All KTI chillers are highly efficient using three- or four-stage cooling, hot-dipped galvanised evaporative condensers, stainless steel heat exchangers, gauges and panel board and at least two- camelwaypressors. The power consumption is between 30% and 50% less than conventional water chillers.
Concrete Cooling is required especially for mass concrete construction for instance in dam projects to avoid the cracks in construction. As the initial and the running costs for such a refrigeration system are quite high (they even can be higher than the ones of the concrete batching plant itself), it is essential for the

needed so the batch control knows when the tank is empty and the valve needs to be closed. A capacitance probe is used as the empty probe, when water hits the probe it is grounded thus producing a signal that there is water against the probe. When used on a transit mix plant the head water should be metered into.
Another option is a consistency meter to monitor and- camelwaypensate for the fines (cement) content in recycled. “grey water”. As an alternative, the required (permissible) consistency of grey water can be input manually. The quality of the concrete produced in a batching plant depends on a whole range of influences.

Used primarily after a Reclaimer, slurry is pumped into a Filter Press, which then uses fluid pressure to dewater the cement fines, creating a dry cake of cement fines and water that can be reused in the batch plant. Once a dewatered cake has been created, the Filter Press opens, releasing the cakes, which can then be
