Pneumatic conveying solution for ammonium sulfate particles
In the transfer and feeding stages of ammonium sulfate granules, traditional manual handling or mechanical conveying often faces issues such as dust dispersion, material moisture and caking, severe equipment wear, and low conveying efficiency. In particular, ammonium sulfate granules are prone to moisture absorption and generally corrosive. If open conveying is used, it not only causes material waste but also pollutes the production environment, increasing subsequent cleaning costs. Enterprises urgently need a sealed, efficient, and low-damage automated conveying solution to reduce labor dependence and enhance workshop safety levels.
Material characteristics

Ammonium sulfate particles are white or light-colored crystals, with particle sizes typically ranging from 1~4mm and a bulk density of about 0.8~1.0 t/m³. This material has strong hygroscopic properties and is easily soluble in water, making it prone to caking in humid environments; At the same time, the pellet surface has a normal hardness, which can be abrasive for conveying pipelines and elbows. Additionally, ammonium sulfate may decompose at high temperatures and release ammonia, so the conveying system must have good sealing, corrosion resistance, and temperature control design.
Product Introduction

The pneumatic conveying system for ammonium sulfate particles launched by Head Powder uses dense or dilute phase positive pressure conveying technology, powered by compressed air, and transports ammonium sulfate particles from the storage silo to the workstation through sealed pipelines. The system consists of a feeding device, conveying pipelines, gas source equipment, dust separation and removal device, and electrical control system. It can be customized with single-point-to-multipoint, multi-point-to-single-point, or ring-shaped pipeline network layouts according to actual process requirements, adapting to downstream equipment such as packaging, reactors, and pelletizers.
Product advantages

To address customers' pain points in dust control, equipment wear, and conveying efficiency, Head Powder offers the following solutions:
- Fully enclosed pipeline transportation: Eliminates dust leakage, reduces the risk of moisture and caking of materials, while meeting environmental emission standards.
- Wear-resistant and corrosion-resistant design: The inner wall of the pipeline uses high-chromium alloy or ceramic lining, with thickened elbows to adapt to the wear characteristics of ammonium sulfate particles; The air source pipeline is equipped with drying and filtration devices to reduce moisture impact.
- Low flow rate is more accurately controlled: Through variable frequency Roots fans and pneumatic valve groups, precise adjustment of conveying speed and air pressure is achieved, helping to achieve a particle integrity rate of >98%, preventing crushing and producing fine powder.
- Intelligent integrated management:P LC+HMI control interface supports remote start-stop, fault alarms, and data recording, can be integrated into enterprise MES systems, reducing manual inspection frequency.
