ceramic foundry sand 20-30mesh sand

1.Product Description

Ceramic sand is also called ceramic sand, is a kind of ceramic particle product with high fracturing intensity, belongs to lightweight aggregate family. Ceramite has excellent properties, such as low density, high cylinder pressure, high porosity, tall softening coefficient, good frost resistance, etc. So ceramite widely used in building materials, gardening, refractory insulation materials, Chemical, oil, gas and other departments. Ceramite sand used more widely with the development of technology.

3.Ceramsite production process:

Product ceramsite generally using the production process of raw material homogenization, granulation, baking, cooling.

According to the type and characteristics of raw materials, Its granulating process can be divided into the following kinds:

1. Plastic method technology: Suitable for clay and clayey material. Its process: Clay - plasticizing, smoothing of roller and granulating - roasting - cooling - finished products.

2. Mud into the ball process: Suitable for fly ash or other powder raw materials. Its process: Fly ash - mixed smoothing - into balls set granulating - roasting - cooling - finished products.

3. Powder grinding ball process: Suitable for shale, clay shale and gangue materials. Its process: Shale, drying, grinding, prewetting - into a ball dish granulating - roasting - cooling - finished product, the additive agent.
