Abstract
A system for conditioning stucco particulate material includes a vessel having separation chamber in communication with a holding chamber having a holding volume therein. The conditioning system includes the holding volume sufficient to condition the stucco particulate material therein and/or a control system configured to delay discharge of the stucco particulate material from the holding chamber. The system for conditioning stucco particulate material is configured to increase residence time of the stucco particulate material in the holding chamber to promote calcining conditioning therein.
Claims17
A system for conditioning stucco particulate material, the system comprising:
- a vessel having separation chamber in communication with a holding chamber;
- the separation chamber having an inlet for supplying the stucco particulate material entrained in a gas, the separation chamber having a collector system configured for separating the stucco particulate material from the gas, the separation chamber having a gas outlet for discharging the gas from the separation chamber, the collector system having a discharge capacity for discharging the stucco particulate material therefrom and into the holding chamber;
- the holding chamber defining a holding volume therein and the holding chamber having a stucco outlet and a conveyor disposed between the holding volume and the stucco outlet for conveying the stucco particulate material through the stucco outlet;
- and at least one of:
- (a) the holding volume is of a predetermined magnitude sufficient to condition the stucco particulate material in the holding chamber, before being discharged through the stucco outlet;
- and
- (b) a control unit in communication with a drive unit connected to the conveyor, a sensor in communication with the holding chamber and the control unit, the sensor being configured to generate control signals at a setpoint and transmitting the control signals to the control unit, the control unit being configured to control the drive unit based upon the control signals, to accumulate and retain the stucco particulate material in the holding chamber for conditioning, before being discharged through the stucco outlet.
