How to prevent bridging in the hoppers of mechanical equipment?

Thread Content

What is bridging in a bridging hopper? It refers to the phenomenon where bulk materials, such as powders or particles, form an arch-shaped structure above the outlet. It hinders the free flow of materials, leading to serious production problems: → Manual intervention is required to loosen the materials → Reduced productivity and machine downtime → Imbalances in the material ratios → Potential damage or contamination of the subsequent batches of materials that are stuck → Waste of materials due to the disposal of spoiled or substandard batches. How to solve the problem of material bridging in hoppers? → Understand the flow properties of the materials. Choose non-sticky materials whenever possible. If bonding the material is necessary, consider using additives to reduce its bonding properties. →Control moisture. Implement appropriate moisture control measures to ensure that the material remains within acceptable levels, thereby maintaining smooth flow. This may include the use of desiccants, heaters, or dehumidifiers. →Choose an appropriate hopper design. Select an appropriate hopper design based on the properties of the material. The angle of the conical hopper ranges from 50 to 60 degrees, and an appropriate outlet size can help facilitate stable flow. →Use the correct flow aid. Many manufacturers use pneumatic flow aids to break up material lumps and ensure a reliable material flow. In addition to accelerating production speed, it can also prevent material buildup or deterioration, as well as the safety risks associated with manual intervention and cleaning. Using AS pulse cleaning systems to address the problem of bridging in hoppers is essential to ensure continuous and efficient flow in industrial processes. Preventing bridging in hoppers is a necessary condition for this. Most brands and small to medium-sized enterprises use the AS pulse cleaning system to achieve smooth on-demand flow. The AS pulse cleaning system is a pneumatic flow-assisting device that incorporates on-site model design and strategic placement, utilizing different flow patterns such as radial flow and impact flow to achieve activation within specific areas and angles. This facilitates overall material flow, eliminates sticking to walls and other flow-related issues, and breaks up bridging phenomena. It is energy-efficient, requires little maintenance, and has proven to deliver excellent results even for the most challenging flow problems. The AS pulse cleaning system can be installed on hoppers as well as other process equipment, such as silos, chutes, conveyor belts, or any locations where materials tend to flow poorly. Since the AS pulse cleaning system relies on releasing powerful pulses of air at high pressure rather than vibration, it does not cause metal fatigue or damage to small or thin hoppers. The AS pulse cleaning system is also ATEX certified, allowing it to be used safely in hazardous and flammable environments, and there are also USDA-certified models designed for hygienic applications.
