Difference of marble powder and calcite powder and their grinding equipments

    Marble and calcite are all normal non-metallic materials, can be process into different fineness of powder which called as heavy calcium carbonate after grinded by grinding mill or other mine equipment, can be widely used in papermaking, plastic, rubber, household chemicals, cosmetics, building materials, paints, pharmaceuticals, food and other industries. Although they all can be processed into heavy calcium carbonate, but they are largely different in performance, the following elaborate from several aspects.

    1. Tell from the ore itself: from the crystal structure of the microscopic point of view, calcite belongs to the hexagonal calcite; marble crystal presented cube shaped. Calcite is cleavage clear and translucent can be divided into large and small calcite; large calcite has high transparency, cleavage of small calcite is relatively disorder. Marble is divided into coarse concentrate and fine-grained ore, the same tone of biased plainer phase, plenty of reserves in domestic, market usage amount is relatively large.

    2.Tell from the powder appearance and content of calcium carbonate: calcite is more soft in pink phase, and also yellowish and reddish phase, calcium content can reach more than 99%; and marble powder slightly plainer, in blue phase, the amount of calcium content is about 96% -98%.

    3. From the grinding difficulty: calcite Moh’s hardness of 3.0, while the marble Moh’s hardness of 3-4, so the process of calcite by grinding equipment is more time saving and high efficiency than marble.

    4. From the powder application performance: Whiteness of good calcite can be 95-97 above (400 mesh powder), calcite powder price is slightly higher than marble powder. Calcite has high purity and its powder can be used in various food grade fields such as, toothpaste, food additives, food calcium, and feed additives and so on. Whiteness of marble is lower, better marble powder whiteness is about 93-95 (400 mesh).

    Guilin Hong Cheng has a wealth of experience in production and application of high-tech in the field of powder equipment manufacturing, the high-performance mill equipment manufactured which is high-end configuration, can provide powder enterprise integrated processing solutions programs including materials testing, product analysis, project reporting assistance, process design, material test grinding, guideline of construction, installation and debugging, training and guidance, project acceptance, after sell services and so on, is a mill machine production base trusted by customers.

    In the field of heavy calcium carbonate grinding, Guilin Hongcheng also has a very rich experience in actual cases, Hongcheng’s heavy calcium carbonate mill is very popular in the market, with excellent performance, smooth operation, high efficiency and energy saving, low maintenance cost performance and other advantages, have a wide range of applications all over the world. HCH ultra-fine mill, can be said professional equipment for HCC grinding, advanced technology of ring roller mill is widely used in talc, calcite, calcium carbonate, dolomite, feldspar, bentonite, kaolin, graphite and other non-metallic materials; product fineness can be freely adjust between 400-2500 mesh, has a very good market prospects, provide a professional and high-end grinding equipment for improve overall competitiveness of enterprises.

    HCH ultrafine mill is a type of ultra fine grinding equipment successfully developed by Guilin Hong Cheng based on accumulation of years of research and development experience, has advantages as following: small footprint, strong completely system, versatile, simple operation, easy maintenance, stable performance, cost-effective, energy-efficient. This mill is operation under negative pressure with increased precipitator efficiency dust catcher, can achieve less dust working environment; semi-automatic control with unique technology, significantly improve production efficiency, is currently one of the lowest energy consumption ultrafine grinding equipment. Especially HCH1395 ultrafine mill is now the largest ultra-fine mill in China, the capacity can reach up to 11t/h, breaking the rule of ultrafine mill cannot achieve large-scale production pattern, is trustable heavy calcium carbonate mill equipment.
