In industries such as chemicals, petrochemicals, and air separation, molecular sieves serve as important adsorption and separation materials. Their conveying stages often face issues such as dust swirling, material damage, pipeline blockages, and low conveying efficiency. Traditional mechanical conveying (such as screws, belts, bucket lifts) not only wear out quickly and have high maintenance costs, but also struggle to achieve sealing and automation, leading to secondary material contamination, harsh production environments, and even reduced adsorption performance. Customers urgently need an efficient, sealed, low-damage, and easily integrated conveying solution.

Material characteristics: The physical and flow characteristics of molecular sieves

Molecular sieve is usually spherical or strip-shaped particles, with a particle size range of about 0.5~5mm, bulk density of 0.6~0.9g/cm³, abundant micropores on the surface, high compressive strength, but moderate brittleness. Its particles easily form fine powder under high-speed collisions, and after absorbing moisture, the surface viscosity increases, making it easy to accumulate at bends or resized pipes. Therefore, the conveying process requires strict control of speed and air volume to avoid breakage and blockage, while keeping the inner wall of the pipeline smooth and configuring a reasonable bending curvature.

Product Introduction: Pneumatic conveying system solution for molecular sieve systems

Head Powder offers customized molecular sieve pneumatic conveying systems, covering multiple conveying modes such as positive pressure dense phase, dilute phase, and negative pressure suction. The system consists of a feeding device, sending tank, pipeline assembly, air source equipment, dust separation and removal device, and an automatic control system. It can be modularly designed according to site layout, conveying distance, and capacity requirements. The conveying pipeline uses wear-resistant stainless steel, with optimized bending radius to facilitate smooth material flow; The air supply is equipped with variable frequency adjustment to effectively match different operating conditions.

Product Advantages: Targeted solutions to customer pain points

To address the core issues in molecular sieve transportation, this solution delivers the following values:
-Low Crushing Rate:The dense phase conveying mode adopts low gas velocity and high material-to-air ratio, with material moving in the form of plug or pulse flow, reducing particle collisions and friction between pipe walls, and the measured crushing rate can be controlled within 0.5%.
-Fully sealed and dust-free:The entire system process is sealed, equipped with a pulse reverse blow dust collector and a high-efficiency gas-solid separation device, ensuring dust emissions meet national standards and improving the workshop environment.
-Anti-clogging design:The pipeline is equipped with automatic blockage removal and pressure monitoring interfaces, and buffer elbows are set along the material flow direction to prevent material accumulation.
-Intelligent Control:Uses PLC + touchscreen host computer to display parameters such as conveying pressure, flow rate, material level, and output in real time, and supports remote monitoring and multi-recipe switching, reducing manual intervention.

Application validation and ongoing service

This solution has been operating successfully for many years in scenarios such as catalyst industry and molecular sieve filling for oxygen generators. Head Powder provides full-cycle services from process design, equipment manufacturing, installation and commissioning to after-sales operation and maintenance, helping the system operate continuously.
