Potential emission sources in gypsum processing plants are shown in Figure 11.16-1. While particulate matter (PM) is the dominant pollutant in gypsum processing plants, several sources may emit gaseous pollutants also. The major sources of PM emissions include rotary ore dryers, grinding mills, calciners, and board end sawing operations.
The research work was focussed on grinding processes of beta gypsum using Pulverisette 6 planetary mill in order to obtain best technological properties. Sulphur binders originate by burnout of calcium sulphate dihydrate at different temperatures. All types are classified in air mortars therefore they can solidify, harden and remain stable only on air.
Ore Classification and Grinding At the manufacturing plant, the gypsum rock is dumped in a covered staging area adjacent to the rock processing equipment area. A frontend loader delivers rock to a Power Screen (SN-63 to separate finer material. The gypsum rock goes to rock bins which feed the two roller mills and the CP mill.
