Process 1: Clay → Plasticization and homogenization → Roller granulation → Roasting → Cooling → Finished product
Process 2: Raw material mixing - granulation - screening - sintering - stacking - transportation (bagging)


(1) Aluminum vanadium clay ceramic sand
Made from various raw materials such as high-quality bauxite and coal, through multiple processes such as crushing, fine crushing, grinding, granulation, and high-temperature sintering, it is characterized by high temperature resistance, high pressure, high strength, strong conductivity, and corrosion resistance. It is mainly used for underground support in oil fields to increase the production of petroleum and natural gas, and is an environmentally friendly product. It is a substitute for medium and low strength proppants such as natural quartz sand, glass balls, and metal balls, which has a good effect on increasing oil and gas production. It is also one of the largest varieties of ceramic sand in current demand, also known as petroleum fracturing proppant ceramic sand.
(2) Fly ash ceramic sand
A lightweight coarse aggregate with a particle size of over 5mm, made mainly from solid waste, added with a certain amount of binder and water, processed into balls, sintered and expanded, or naturally cured, is abbreviated as fly ash ceramic particles.
(3) Clay ceramic sand
Light coarse aggregates with a particle size of over 5mm, mainly made from clay, sub clay, etc., processed and granulated, are called clay ceramic particles.
(4) Shale ceramic sand
Also known as expansive shale. Shale ceramic particles are light and coarse aggregates with a particle size of over 5mm, which are formed by crushing, screening, or grinding clay shale, slate, etc. into balls, and then burning and swelling. Shale ceramic particles can be divided into ordinary shale ceramic particles that have been crushed, screened, and expanded by firing according to the process method; Spherical shale ceramic particles formed by grinding, balling, and burning.

(5) Garbage ceramic sand

(6) Coal gangue ceramic sand


(7) Biological sludge ceramic particles

(8) River bottom mud ceramic particles
