Gypsum powder production line has the advantages of First grind and
second bake.
Large plaster stone shall be ground into powders with diameter less
than 0.2mm, which increases the specific surface when calcining,
enlarges the contact area with heat medium, improves calcination
heat exchange efficiency and lowers energy consumption greatly.
This equipment has small bulk, large production capacity, and
simple structure and is hard to destroy.
Analysis on technique
features:
I. Concept of technique
Crusher grinds large gypsum into small granules less than *5mm.
After storage and measurement with weigh belt, transfer them into
Raymond mill for milling. Transfer qualified calcined gypsum powder
to clinker bin for storage or to board-manufacturing workshop for
usage.
II. Technique's advantages:
1.Features of first grind and second bake:
Compared
with that of first grind and second bake, the largest advantage of
this technique is great energy consumption reduction. The reason
lies in: great plaster stones are ground into powders with diameter
less than 0.2mm, which increases the specific surface when
calcining, enlarges contact area with heat medium, improves
calcining heat exchange efficiency and lowers energy consumption
greatly; the disadvantages are three powder pollution positions in
technical process, which shall be solved with dust-removing
equipment.
2. Features of two other techniques:
First bake and second grind: due to high energy consumption and
low production capability of this technique and that the quality of
the products is hard to control and is unstable, at present, it is
a kind of backward technique and is seldom adopted. Only a few
small factories are still applying it.
Integration of grind and bake: this technique has good features:
low energy consumption, small investment, high efficiency, stable
quality of the products and small area coverage. Besides, the dust
volume is concentrated and is easy for protecting environment.
However, it is not mature at home and only BNBM imported from
German one set of Peters-mill, which runs to manufacture thistle
board.
