By ceramic shape classification

Ceramic according to shape into gravel-type ceramic, spherical and cylindrical ceramic ceramic.
(1) gravel-shaped ceramic
Gravel-type ceramic proppant general use natural mineral production, the first stone grinding, roasting, and then sifting; also available in natural and artificial light materials such as pumice, scoria, cinder, coal and other natural or calcined directly broken screen points derived.
(2) spherical ceramic
Spherical ceramic production is the use of the disc pelletizer. First raw flour, then add water pelletized into balls and then baking or curing together. At present, China's resin coated ceramic proppant Most of this variety.
(3) a cylindrical ceramic
Cylindrical ceramic commonly used plastic extrusion. First made of mud, and then cut into a cylindrical shape. This ceramic ball is suitable for high plasticity clay like material, the yield is relatively low. If using a cylindrical blank brick back firing in the kiln cylinder roll into an oval shape.
