Good quality and stable performance
Because adopt low-temperature heat source, so the gypsum is not easy to be burnt, as long as the temperature is
controlled properly, there will not have CaSO4 2H2O in the finished product, and the anhydrous gypsum is
within 5%, and the rest are CaSO4 1/2H2O.
In order to reach the above requirement, our company have researched and developed a whole set of boiling furnace
processing technology, the main material is good-quality steel. For example, heat conductive oil pipe adopts seamless
steel pipe (GB3087-82). Steel plate adopts carbon steel and low-alloy steel (GB713-86);Frame steel adopts international
product. Furthermore, in the work of welding, all the workers have work certificate, after welding, the coil pipe will have
a water pressure test, just in case of leakage of heat conductive oil. The product is qualified if there is no leakage under
the water pressure of 1.0~1.5Mpa for 24 hours.
Technology introduction of boiling furnace
With the development and progress of gypsum industry, the need of gypsum powder is growing, also with the quality
of gypsum powder. During the whole procedure, the drying and dehydration are the key link, and it is also the
difficult part. According to such a condition, after many years researching and exploring,we have developed a new
generation dehydration device which are suitable for all kinds of gypsum production demand boiling furnace.
Principle of working
The main principle of drying system: the boiling furnace body is consist of delicate and intensive cooling coil pipe. Put
the heat conductive oil in the pipe, and release the heat into the inside of furnace. There is a Roots blower under the
bottom of boiling furnace, and blow the air into the furnace, until blowing the powder into boiling status. Under a certain
temperature, the dried and dehydrated powder become light, and flow to the outlet automatically. The quality of this kind
of gypsum powder is stable, because the equipment adopts dried electrostatic dust remover, so the dust-removing
efficiency is above 95%.
