2.3 MANUFACTURING PROCESS The manufacturing process begins with selection of raw quartz materials. They are crushed and blended in the ratio of 93 % quartz aggregates to 7% polyester resin and other additives. The mixture is compacted into slabs by a vacuum and vibration process of approximately 100 seconds at a pressure of about 100 tons.

The crushed stone production technology looks like this: - these products are made by crushing; - then it is sorted by size. General characteristics of crushed stone production equipment. This is one of the main issues. The choice of equipment type will depend on what kind of raw materials the crushed stone production plant will process.

Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

the economic well-being of a nation. The demand for crushed stone is determined mostly by the level of construction activity, and, therefore, the demand for construction materials. The production of crushed rock aggregate involves the process of mining known as quarrying and it also has some
