Project background of the Yunnan white lime powder production line

The Yunnan white lime powder production line has advantages not only in the efficient utilization of the local abundant and high - quality limestone resources, but also in the Raymond mill equipment in the production process. This production line adopts advanced equipment such as the CRRM1700 Raymond mill, which can grind efficiently and precisely control the particle size of the discharged material, meeting the fineness requirement of 200 meshes. It features high production efficiency, low energy consumption, and is cost - effective. The production line is equipped with a complete dust removal system, effectively treating dust in all links, reducing pollution, and being environmentally friendly. 

The process of tehe white lime powder production lin

From raw material to grinding: The quicklime raw materials are stored in the raw material bin. After the production line starts, the belt feeder outputs the raw materials from the raw material bin and continuously and smoothly conveys them to the feeding port of the CRRM1700 Raymond mill through the belt. The belt feeder can accurately control the material conveying volume to ensure the continuous and stable grinding of the Raymond mill. After the materials enter the Raymond mill, the grinding roller and the grinding ring cooperate closely. Under the action of centrifugal force, the grinding roller presses against the grinding ring, and the shovel blade shovels the materials and sends them between the grinding roller and the grinding ring. The materials are gradually crushed into small particles, and the Raymond mill transforms the quicklime raw materials into powder that meets the fineness requirements.

Powder Collection and Dust Removal: The materials ground by the Raymond mill turn into fine powder, which is carried out by the air flow of the fan and enters the powder collector. The powder collector uses centrifugal force and gravity to separate the powder from the air flow. The heavier powder particles are thrown towards the inner wall of the powder collector and then slide down to be collected at the bottom, while the lighter particles and the air flow continue to move upward.

During the production process, dust will be generated. To avoid environmental pollution and harm to the health of operators, the production line is equipped with a dust collector. The dust collector adopts advanced filtration technology. The air flow containing dust first passes through a pre - processor to preliminarily separate larger particles, and then passes through a filter element to intercept tiny particles. Clean gas is discharged from the air outlet, ensuring that the dust content of the discharged gas is less than 10mg/m³, far lower than the national environmental protection standard (≤30mg/m³), achieving green and low - carbon production.

Subsequent transportation and discharging: After being collected by the powder collector and dedusted by the dust remover, the white lime powder enters the air chute. Under the action of the air flow, it remains fluidized and slowly flows forward along the chute, being transported to the next process smoothly, efficiently, and with low energy consumption. Then, the white lime powder reaches the bucket elevator, is vertically lifted to an appropriate height, and then poured into another section of the air chute to continue being transported to the finished product silo for storage, waiting to be shipped to the market to meet the needs of industries such as construction and chemical engineering. The entire process is closely connected.

Operating effect: Since the system was put into use, the production capacity has stably reached 15 tons per hour. The fineness of the finished product is adjustable (80 - 400 mesh), the dust removal efficiency exceeds 99.5%, about 20 tons of dust emissions are reduced, and the energy consumption cost is decreased.

Summary

The Yunnan White Lime Powder Production Line project integrates high-quality resources and advanced processes, achieving breakthroughs in economy, environmental protection, and energy efficiency. Its core equipment, the CRRM1700 Raymond Mill, has a stable production capacity of 15 tons per hour, adjustable fineness, and low energy consumption. The production line adopts an integrated design, features high - efficiency dust removal, and has a low dust emission, with an annual dust reduction of approximately 20 tons. The intelligent feeding system seamlessly connects with the equipment, increasing logistics efficiency by over 30%.
