About Crushed Ceramic Grains

This is produced by Crushing 90% Min Alumina Ceramic Grinding media, plates and other shapes.

Chemistry :

Type	Spec		Typical
90% min Ceramics Grains	AI2O3	90%min	92
	SiO2		6.5%
	Others		1.5%
	B.D:		3.6

Due to its toughness, low porosity, high refractoriness Ceramic grains can replace White tabular alumina partly in Various applications. This is very cost effective.

Fused AZS Fines :

Fused Alumina Zirconia Fines is produced from the fines generated by the surface grinding of Fused Electrocast Refractory Blocks when it is being finished.

Type	Spec		Typical
Fused AZS fines	AI2O3	50% min	52%
	SiO2	14-18%	16%
	ZrO2	34-38%	36%
	B.D:	-	3.6

Application : Due to its high density and low porosity AZS fines replaces Calcined Bauxite in various applications. Fused AZS fines exhibits high refractoriness and can be used in castables as a cost effective additive.

Superior Performance Across Applications

Crushed ceramic grains excel in abrasive blasting, surface preparation, refractory liner filling, and polishing. Their combination of high hardness (Mohs scale 78), low friability, and excellent resistance to acids make them ideal in demanding industrial settings. Their ability to withstand high temperatures without significant expansion or loss in strength ensures reliability in both hot and corrosive environments.

Reliable Physical and Chemical Properties

Engineered for superior performance, these grains offer a bulk density of 1.51.7 g/cm, a specific gravity of 2.62.8 g/cm, and porosity typically less than 5%. With high compressive strength and dimensional stability, their composition delivers consistent results, especially in refractories and abrasive processes. The products matte, rough finish and beige to light brown color distinguish it visually and functionally.

FAQs of Crushed Ceramic Grains:

Q: How are crushed ceramic grains used in abrasive blasting and surface preparation?

A: Crushed ceramic grains, due to their angular, irregular shape and high Mohs hardness (78), are highly effective as abrasive media for blasting and cleaning surfaces. They help remove coatings, contaminants, and rust while providing an ideal surface profile for further processing or coating.

Q: What benefits do crushed ceramic grains provide as a refractory filler?

A: These grains are valued for their excellent dimensional stability, low thermal expansion (0.50.8% at 1000C), high compressive strength, and resistance to acids. Such properties ensure reliable performance and longevity in refractory linings even at temperatures up to 1500C, reducing shrinkage and chemical degradation.

Q: When should I opt for customized particle size?

A: Customized particle sizesranging from 0.5 mm to 5 mmallow you to match the grain size to your specific application, such as abrasive blasting for coarse removal or fine polishing. The proper size enhances efficiency, surface finish, and material compatibility in industrial processes.

Q: Where can crushed ceramic grains be stored to maintain their properties?

A: To preserve their physical and chemical integrity, these grains should be stored in dry, cool environments. Proper storage prevents moisture absorption (water absorption <0.5%), maintaining low porosity and maximizing performance over time.

Q: What is the process for exporting or importing this product in India?

A: Crushed ceramic grains are packaged in HDPE bags or bulk containers suitable for transport. As exporter, importer, or supplier, ensure compliance with material safety data regulations and coordinate logistics with reliable freight partners for timely delivery to industrial users.

Q: How does the chemical composition affect usage and durability?

A: The blend of Al2O3, SiO2, and minor oxides imparts excellent resistance to acids and good alkali resistance, while ensuring high compressive strength and low friability. This results in grains that are durable, non-toxic, and suitable for extended use in harsh environments.
