Hydrated lime powder, also known as calcium hydroxide, is a widely used material in industries such as environmental protection, construction, chemical processing, and water treatment. Its fine, dry, and abrasive nature poses unique challenges for material handling. A reliable and efficient pneumatic conveying system is essential to transport hydrated lime powder from storage to processing points without dust leakage, degradation, or clogging. This article, provided by Shandong Headpowder Engineering Co., Ltd. (brand: headpowder), presents a comprehensive solution for hydrated lime powder pneumatic conveying, covering system design, key components, operational advantages, and application scenarios.
Hydrated lime powder typically has a bulk density ranging from 400 to 600 kg/m³, a particle size of 0.5 to 50 microns, and a high tendency to absorb moisture and agglomerate. These characteristics make it one of the most challenging powders to convey pneumatically. The hydrated lime powder conveying process must be designed to prevent bridging, blocking, and dust emissions. Shandong Headpowder Engineering Co., Ltd. has developed specialized pneumatic conveying systems that address these issues through precise air velocity control, optimized pipeline routing, and the use of abrasion-resistant materials. The system ensures that the hydrated lime powder remains free-flowing and maintains its chemical properties throughout the conveying process.
A complete hydrated lime powder conveying system from headpowder consists of several key modules: a feeding device, a conveying pipeline, a separation device, and a control system. The feeding device, often a rotary valve or screw feeder, ensures a consistent and metered flow of hydrated lime powder into the conveying line. The conveying pipeline is made of wear-resistant steel or ceramic-lined pipes to withstand the abrasive nature of the powder. At the discharge end, a cyclone separator or bag filter separates the powder from the conveying air, allowing the lime to be collected in a silo or directly fed into a process vessel. The entire system is controlled by a PLC-based automation unit that monitors pressure, airflow, and material flow rate, ensuring stable and efficient operation.
When selecting the conveying mode for hydrated lime powder pneumatic conveying, two main options are available: dilute phase and dense phase. Dilute phase conveying uses high air velocity (typically 20–30 m/s) to suspend the powder in the air stream, suitable for shorter distances and lower capacities. However, for hydrated lime powder, dilute phase can cause higher wear and dust generation. Shandong Headpowder Engineering Co., Ltd. often recommends dense phase conveying for hydrated lime powder, where the material is pushed through the pipeline at low velocity (1–5 m/s) in a plug or slug form. This approach reduces pipe wear, minimizes dust, and lowers energy consumption. The hydrated lime powder conveying system designed by headpowder can be configured for either mode depending on the specific site conditions, conveying distance, and capacity requirements.
The hydrated lime powder conveying system from Shandong Headpowder Engineering Co., Ltd. offers several distinct advantages. First, it achieves a high material-to-air ratio, which improves conveying efficiency and reduces compressed air consumption. Second, the system is equipped with a self-cleaning filter and anti-clogging design to handle the hygroscopic nature of hydrated lime powder. Third, the entire system is enclosed, ensuring zero dust emission and a clean working environment. Fourth, the modular design allows for easy maintenance and scalability. These features make the hydrated lime powder pneumatic conveying solution from headpowder a reliable choice for industries that require continuous, safe, and cost-effective transport of lime powder.
The hydrated lime powder conveying system developed by Shandong Headpowder Engineering Co., Ltd. is widely used in flue gas desulfurization (FGD) in power plants, water treatment facilities, construction material manufacturing, and chemical processing. In FGD applications, hydrated lime powder is injected into the flue gas stream to neutralize acidic gases; the pneumatic conveying system must deliver the powder precisely and consistently. In water treatment, hydrated lime is used for pH adjustment and softening; the conveying system feeds the powder into mixing tanks without spillage. In construction, hydrated lime is a component of mortar and plaster; the system transports the powder from bulk storage to batching units. Each application benefits from the customized design provided by headpowder.
When planning a hydrated lime powder conveying system, Shandong Headpowder Engineering Co., Ltd. takes into account several critical factors: the physical and chemical properties of the lime powder, the required conveying capacity (typically 1–50 tons per hour), the conveying distance (up to 500 meters), the available space for equipment, and the existing plant layout. The company also considers the risk of moisture absorption and provides options such as heated air drying, dehumidified conveying air, or pneumatic fluidizing hoppers to maintain powder flowability. The pipeline routing is designed with minimal bends and a gradual slope to reduce pressure drop and wear. All these considerations ensure that the hydrated lime powder pneumatic conveying system operates with maximum uptime and minimum maintenance.
