Why is a dust collector installed on the bin top?

1. Solve ash spillover of powder bin under pressure and achieve environmental protection compliance

The powder bin is a closed tank structure. When the tank truck is pneumatically fed, a large amount of compressed air will instantly flow into the bin to form a high positive pressure. If there is no special dust removal equipment, the high pressure dusty air flow cannot be dredged normally, which will overflow from the air vent, access hole and flange gap on the bin top and cause continuous dust pollution. The bin top dust collector can quickly balance the air pressure in the bin, effectively filter the ultra-fine dust, eliminate the dust emission on the bin top from the root, regulate the dust control in the plant area, meet the requirements of clean production and environmental protection management and control in the cement industry, and avoid the hidden dangers of excessive dust.

2. Balance the air pressure in the bin to ensure the stable operation of production equipment

Unbalance of air pressure in powder bin is the key factor affecting production efficiency. Long-term pressure holding in the bin will increase the resistance of pneumatic conveying, resulting in slow feeding, air return and blocking; Negative-pressure imbalance during unloading may easily lead to material bridging, material jam and inaccurate blending. The bin top dust collector has the function of continuous ventilation and pressure relief, which can dynamically balance the positive and negative air pressure in the bin, ensure smooth air flow in the whole process of feeding, unloading and blending, stabilize the powder conveying efficiency, reduce production jam and shutdown faults, and improve the operation stability of the whole production line.

3. Recover superfine powder and reduce loss of production materials

Fine particle size and strong floatability of powder materials. Without dust removal equipment, a large number of fine powder materials will directly drift with the air release flow, resulting in intangible loss of materials and large long-term accumulated loss. Suspended dust is intercepted by the bin top dust collector through high-precision filter element, filtered clean air is discharged, and the retained powder automatically falls back into the bin to realize dust recycling. It can not only reduce waste of raw materials and control production costs, but also avoid equipment corrosion and site pollution caused by dust accumulation.

4. Eliminate dust hazards and improve the safe production level of the plant area

The concentration of suspended dust in the closed powder bin is too high, and it is easy to form suspended dust cloud due to long-term accumulation, which has potential safety hazards. The bin top dust collector continuously filters the suspended dust in the bin, reduces the dust concentration in the bin, avoids a large amount of dust accumulation, and effectively reduces the safety risk of powder storage. Meanwhile, clean production environment can reduce ash accumulation on equipment surface, reduce ash accumulation failure probability of circuit and mechanical parts, and optimize safe production in plant area.
