The company is a local building materials company which has been engaged in limestone grinding production and sales for a long time. The company adopts a scientific management style. Due to the development needs of the company, it is necessary to develop high quality limestone products with good purity and microfine particle size. After many understanding and field investigation, they were attracted by Kolev's professional technology and excellent process, specially introduced our advanced equipment technology and purchased our full set of limestone grinding production line.

The set of limestone grinding production line is composed of storage hopper, grinding host, feeding system, dust collector system, conveying system and electric control system, etc.The detailed technological flow is as follows: firstly, the limestone materials are sent to the storage hopper, and then evenly and quantitatively sent into the grinding chamber of the mill for grinding by the feeder. Secondly, the ground materials are graded by the grading system, and the unqualified powders are graded by the grader and returned to the main machine for regrinding. The powders that meet the fineness are separated and collected by the airflow into the dust collector, and the collected finished powders are discharged by the outlet. The whole grinding system is a negative pressure cycle, equipped with pulse dust collector device, environmental protection without dust.

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: Negative pressure work, energy saving and environmental protection, safety and stability, CNC frequency conversion, uniform fineness of finished products, adjustable particle size, through the screening rate of 99%, which can meet the high grade building production material standards. 3: The grinding roller adopts oil-immersed lubrication system and Marine sealing device, greatly prolonging the service life of the mill. 4: The overall efficiency of the equipment is high, easy to operate, convenient to maintain, safe and stable, and with high cost performance.
