This company is a local lime production enterprise integrating production, deep processing and sales. The company mainly engages in calcium hydroxide, ash calcium powder, heavy calcium carbonate, and light calcium carbonate, etc. All of them are made of high quality raw materials with advanced equipment and production technology, and the products are widely used in coating, building materials, sewage treatment and other fields. Due to the development needs, they need to add a limestone processing production line. After various communication, project analysis and field investigation, they were moved by the sincerity and professionalism of Kolev company, and purchased the complete set of limestone grinding production line.

The production line of limestone grinding powder is composed of silo, electromagnetic vibration feeder, grinding host, powder collector, dust collector system, fan and conveying system. The detailed technological flow is as follows: limestone raw materials fall into the vibration feeder from the silo, and then are evenly transported to the mill by the electromagnetic vibration feeder for grinding. The ground powders are blown into the analyser of the mill under the action of the blower for sorting, and the powders that does not meet the fineness requirements are sent back to the grinding room for grinding. The powders conforming to the fineness enter the cyclone collector with the air flow, which are separated and collected, and then discharged through the powder discharge tube to get the finished powders.

1: The overall production line has a high degree of automation and simple process. In addition to the startup, shutdown and daily maintenance of the equipment, there is almost no need for manual operation, which can save time and cost while ensuring the grinding efficiency. It is very suitable for the future development of the grinding market. 2: The finished product has uniform quality, excellent grain shape, and can meet the material standards for high-grade construction production. 3: The grinding roller device uses thin oil lubrication, no frequent refueling, more convenient than grease lubrication, and lower maintenance cost. 4: The wear parts of the set of equipment adopt high strength wear-resistant materials, small loss, long replacement cycle, and prolong the service life. 5: Negative pressure work, and equipped with professional dust collector device, environmental protection without dust.
