There are two types of abrasive materials used in sand blasting; coarse and fine-grained aggregate. Rough aggregates are those that consist of smaller grains than fine grains. Grinding occurs when fine particles are turned into larger grains by crushing Visit us at www.stonecleaningexperts.co.uk. This grinding process produces fine particles that can be used in sand blasting. Fine-grain aggregate includes coarse grains. These coarse grains have a larger diameter than their rough counterparts. These coarse grains are the product of grinding. As the grinding process continues, the coarse grains become finer in size. At this point, the coarse grains can be used for sand blasting purposes.
