The difference between calcite and crystal and calcite processing production line
Both calcite and crystal are naturally occurring lens minerals. Because of their similar appearance, they are easily confused by people. But the market prices of the two are very different. What is the main difference between calcite and crystal? How to distinguish? Although the value of calcite is not as good as crystal, the use of calcite is very extensive in industry. The calcite powder produced by calcite processing is an important filler in many industries.
The difference between calcite and crystal
Calcite is the main mineral of limestone and marble, and it is the most common natural calcium carbonate. Therefore, calcite is a widely distributed mineral. Calcite has a variety of crystal shapes, and their aggregates can be clusters of crystals, granular, massive, fibrous, stalactite, earthy, and so on. Calcite has a glassy luster, transparent to translucent, usually white or colorless, and contains many other colors, such as light yellow, light red, brown black and so on when it contains iron and manganese. The hardness is 3.0, the specific gravity is 2.6～2.8, and it foams violently when exposed to cold and dilute hydrochloric acid.
Crystal is a pure, colorless and transparent large-scale quartz crystal mineral. Its main chemical component is silicon dioxide. Because it contains different mixtures or mechanical mixtures, it shows a variety of colors. Those containing manganese and iron are called amethysts, those containing iron (golden or lemon-colored) are called citrines, those containing manganese and titanium that are rose-colored are called rose quartz, that is, pink crystals, those with smoky colors are called smoky quartz; Citrine; black and transparent is called smoky crystal. The hardness of crystal is very high, generally reaching above 7, and it can be used for optical instruments, jewelry and decoration.
How to distinguish calcite and crystal
1. Drop dilute hydrochloric acid on the surface, the calcite will foam immediately, but the crystal will not react.
2, the hardness of crystal is 7, and the hardness of calcite is 3. With a small knife, the calcite will be drawn with a line, and there is no trace of the crystal.
Calcite processing production line
Calcite processing powder is currently the most important way of utilization. Calcite powder can be widely used as filler in artificial stone, rubber, paint, plastic, cable, paper, toothpaste, cosmetics, glass, medicine, paint, ink, cable and other industries.
Clirik can design a special calcite processing production line according to the actual needs of customers. The HGM vertical mill developed by Clirik is a reliable equipment for producing calcite powder. The calcite processing production line is mainly composed of the main engine, feeder, classifier, blower, pipeline device, storage hopper, electric control system and collection system. The equipment is simple in structure, stable in operation, good in product quality, less dust in the grinding process, and high in automation.
