CORIMASS G+ improves plaster blending

(CORIMASS has now been replaced by the more advanced OPTIMASS)
Problem
A wall board manufacturer in Ontario, Canada was using mass meters to control the distribution of plaster media during the manufacturing process. The mass meters’ volumetric measurement was fooled by the varying density of the plaster and resulted in an inconsistent product because either too much or too little plaster was used. The wall board manufacturer was reworking a significant portion of the out of spec material at a large expense. In addition to the blending issue, the manufacturing cycle time was drawn out and the media would begin to set and harden in place. Again when this occurred, the product was scrapped. The plant needed to increase efficient production levels of the plaster batching process, as well as the process cycle time. If those two goals could be reached, the reoccurring amount of wasted product would drop and the company would save a considerable amount of money.

Solution:
Initially, the plant installed a competing type of mass meter to improve their efficiencies, but discovered that the meter would have to be replaced one to two times a year when the plaster hardened onto it. Next they tried the KROHNE 3000 G+ Class CORIMASS Flowmeter and quickly saw that the large thru put and a single straight tube reduced the pressure drop. The meter could be easily removed from the line if it became clogged and operators could run a rod thru the unit to ease any congestion.

The 3000 G+ Class provided the optimum performance in the harsh manufacturing environment. Total installed cost was less than $25,000, and resulted in an economical solution to a costly problem. G+ Class CORIMASS Flowmeters are now this plant’s standard.
