As an ultrafine powder, nano calcium carbonate often faces challenges such as flying particles, pipeline blockages, and moisture absorption and caking during transportation. Traditional mechanical conveying methods not only generate a large amount of dust pollution, but also frequently stop for maintenance due to materials that easily stick and agglomerate, seriously affecting production continuity and product quality stability.

Material characteristics

The particle size of nano calcium carbonate is usually between 20~100 nanometers, with a large specific surface area and high surface energy, showing a strong tendency for agglomeration. It has poor flowability, obvious static friction effects, is sensitive to humidity, and easily absorbs moisture and forms caking. These characteristics make it difficult for conventional pneumatic conveying equipment to achieve smooth and efficient transfer operations.

Product Introduction

Head Powder has launched the nano calcium carbonate pneumatic conveying system, which uses a combination of sealed pipelines and positive/negative pressure conveying methods, specifically designed for ultra-fine, dust-prone and moisture-absorbing powder materials. The system consists of a feeding device, conveying pipelines, air source equipment, dust separation and removal device, and an intelligent control system. It can flexibly configure single-point or multi-point feeding schemes according to production needs, achieving fully enclosed transfer from raw material warehouses to production lines.

Product advantages

To address the pain points of Nano Calcium Carbonate, such as being easily clogged, easily floating, and prone to moisture absorption, this system provides the following solutions:

• Using anti-stick slip material and fluidized blowing technology effectively reduces material adhesion and bridging risks on pipe walls;
• Equipped with high-efficiency pulse dust removal and automatic back-blowing devices to help clean exhaust and meet environmental emission standards;
• The system's overall sealing design combined with dehumidification pretreatment prevents moisture absorption and caking of materials;
• Programmable logic controllers (PLCs) combined with touchscreens enable fully automated operation, monitoring conveying pressure, flow, and blockage anomalies in real time, reducing manual intervention.
