This company is a local chemical building materials enterprise based on the development and utilization of local resources, which is the backbone of the local production of high-quality bluestone and other stone series products. Due to the company's development needs, they want to add a bluestone processing line. After many comparisons and repeated visits to the plant, they were attracted by Kolev's professional technology and excellent process and purchased a complete set of bluestone grinding production line equipment.

The set of bluestone grinding production line is composed of crushing system, bucket elevator, silo, electromagnetic vibrating feeder, grinding host, conveying system, powder collecting system and electric control system, etc. The detailed process flow is as follows: firstly, the large bluestone raw materials are sent to the jaw crusher to be crushed into small pieces and then sent to the silo. The granules of bluestone are evenly conveyed from the silo to the mill through the electromagnetic vibrating feeder. Secondly, the materials are shoveled up by the scraper and sent between the grinding rollers and the grinding ring. The materials are crushed by the rolling of the grinding rollers, and the materials that meet the requirements enter the powder collector through the analyzer, while the materials that do not meet the requirements fall back into the mill and are ground again until they reach the size that can be passed. Finally, the finished products are sent to the corresponding finished product bin by the powder collecting system.

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: More compact structure design, superior performance, stable air volume and pressure, low failure rate, more convenient installation and adjustment. 3: The grinding roller adopts oil-immersed lubrication system and Marine sealing device, which greatly prolongs the service life of the mill. 4: Negative pressure work, energy saving and environmental protection, safety and stability, CNC frequency conversion, dust removal effect fully meet the national standards. 5: The long replacement cycle of wearing parts prolongs the service life.
