Chalk is a kind of sediment of fine calcium carbonate, and is a variant of calcite. Chalk is mainly composed of the remains of single-celled plankton. It is soft and always appears white, the hardness of 3.
Chalk is widely distributed over the world. At the same time, it has a wide application in the industry. It can be used as the raw material of lime and cement, and as filler of rubber and paint. Chalk can be even used as medicine. It is also used to manufacture chalk, pigments, pharmaceuticals, paper, toothpaste, and so on.
Essexco county of New York and Jiangxi Province of China are the most famous places of chalk origin. But the best natural chalk comes from England, where about 500 tons of chalk produced every year.
First of all, transport the chalk to the jaw crusher evenly and continuously by vibrating feeder for primary crushing. Then, send the crushed chalk to cone crusher or impact crusher for secondary crushing. Vibrating screen is used to separate the materials into different sizes. If the size of particlemeets the requirement, it will be transported to grinding mill for further processing. While the rest part will be send to cone crusher for re-crushing. In this way, forms a circle chalk processing line. In the whole plant, belt conveyor is used to transport materials. It can improve the efficiency and degree of automation greatly.
Jaw crusher: Raw chalk ores are always very large, so we need a jaw crusher to crush the ores into small pieces at first. As the professional mining equipment manufacturer, we provide high efficiency jaw crusher. It adopts advanced technology from the world. And it is made of quality materials, so the service time is long. It has reached the world advanced level through continuous improvement and optimization by our experienced engineers. Because of quality product and attentive service, our jaw crusher is widely used in primary crushing of various industries.
Cone crusher: Cone crusher is ideal equipment used in secondary, tertiary and fine crushing stages. It adopts laminated crushing principle, which not only reduces wearing parts consumption and prolongs its service life, but also significantly increases the proportion of the cube. It also adopts over iron protection device to ensure the machine quickly return to normal operation when debris get in the crushing chamber.
Impact crusher: You can choose impact crusher as the secondary crusher instead of cone crusher. Impact crusher has high crushing ratio, high efficiency and low energy consumption. The hammer is made of advanced material with high impact resistance and abrasion resistance, effectively extends the service life of wearing parts. Customers can easily control the final size of the products by adjustingthe discharge port device.
Chalk has a wide application. The chalk ores processed by our equipment are in great quality, even and fine. Our jaw crusher, cone crusher and impact crusher all adopt the world’s advanced manufacturing technology unique design. And they all optimized according to customers’ requirement. The chalk processing line introduced above has large production, little downtime and repair time. If you have any special requirement, our experienced engineers can design a new chalk crushing line for you. You only need tell us your needs of output and degree of fineness.
