Quartz sand, which is processed from quartz ore using grinding mills, is used in the production of glass - fiber - reinforced concrete (GFRC) and as a filler in some types of mortar. In GFRC, the quartz sand helps to improve the mechanical properties of the concrete, such as its strength and durability.
In mortar, the quartz sand acts as a filler, reducing the amount of cement required and also improving the workability and strength of the mortar. The grinding mills are used to produce quartz sand with a specific particle size distribution, which is crucial for its performance in these applications.

In addition to these, non - metallic mineral powders such as talc and mica are also used in the construction industry. Talc powder can be added to paint and coatings used on buildings to improve their weather - resistance and scratch - resistance. Mica powder is used in some types of decorative coatings to add a shimmering effect. Grinding mills are used to process talc and mica ores into fine powders suitable for these applications.
In conclusion, non - metallic ore grinding mills are indispensable in the construction industry. They enable the production of high - quality non - metallic mineral powders that are essential for various construction materials, contributing to the strength, durability, and aesthetic appeal of buildings.
