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 scientific management. Due to the development of the company, they need to develop high quality limestone series products with good purity and microfine particle size, etc. After many understanding and field investigation, they were attracted by Kolev's professional technology and excellent process, so they introduced our advanced equipment technology and purchased a full set of limestone grinding production line.

The production line of limestone grinding powder is composed of storage hopper, grinding main machine, 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 the feeder will evenly and quantitatively into the grinding room of the mill for grinding. Secondly, the materials after grinding are graded by the classification system, and the unqualified powders are graded by the classifier and returned to the main machine for re-grinding. The powder conforming to the fineness enters the dust collector with the air flow through the pipeline for separation and collection, and the collected finished powders are discharged through the discharge port. The whole grinding system is negative pressure circulation state, equipped with pulse dust collector device, environmental protection and no 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%, 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, the operation is simple, the maintenance is convenient, the safety is stable, with excellent cost-effective.
