Diatomiste Calcining Plant

Diatomite in its natural state is a soft rocklike material consisting esentially of the skeletal remains of a variety of singlecelled microscopic plants known as diatoms. They are generally amorphous, hydrated or opaline silica, SÌO2 x n. H2O, with various
amounts of impurities such as silica sand, clay minerals, metal salts and organic matter. Because of these contaminants, silica content may range from 58 to 90% of the dry product. As mined, diatomite may contain from 10 to 60% of free water. Size
of diatoms varies between 20 to 200 microns. The most important properties of diatomite are its porosity (80-85%), low density (1.95 to 2.3g/cm3) and whiteness (as high as 96). The color of diatomite changes depending on the impurities present in the
sand. For example an increase in the amount of organic matter causes the color to change from white to brown or even to green. Diatomite is not dissolved in acidic solutions except in hydrofluoric acid but it dissolves in concentrated alkaline solutions. The hardness of the diatom skeleton is between 4-6.5 on the Moh's scale the same as opaline silica. Heat conductivity of diatomite is low; 0.08-0.1-0.11 kcal/m.°C.h at temperatures of 300, 800-1200°C respectively. Its melting point is PCE 8-33 and the pressure resistance is between 3-18kg/cm2.  Contact with via skype:gary102884 if need our machine. In order to raise up automation degree, the industrial has been used at the kiln head for monitoring of kiln.

1. Support device: advanced shaft structure, automatic temperature measuring device and electrical heating,.
2. Catch wheel : including two kinds mechanical wheel and hydraulic pressure
3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable , energy-saving, and efficient.
4. Cylinder tyre bolster: lower bolster has three types: fixed , zoom and floating. The structure is simple , replacement is convenient and won’t hurt cylinder.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing , graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good.
6. Kiln head hood: including stationary type and flexible type
