Bitumen and asphalt are among the most challenging materials to store and handle due to their high viscosity, temperature sensitivity, and tendency to stratify during long-term storage. KEHENG Side Entry Mixers provide reliable circulation, uniform heat distribution, and long-term product stability while minimizing operating costs.
Even minor temperature differences within a storage tank can result in substantial viscosity variations, directly affecting circulation, pumping performance, and product consistency.
Causes uneven viscosity and pumping instability.
Reduces effective storage volume and increases maintenance.
SBS and EVA additives may separate during long-term storage.
High viscosity causes flow restrictions and energy loss.
KEHENG Side Entry Mixers are specifically engineered for large bitumen and asphalt storage tanks where continuous circulation and temperature uniformity are essential.
Designed for stable low-speed operation under high-viscosity conditions.
Strong axial flow with reduced energy consumption.
Improves temperature uniformity and reduces thermal losses.
Heavy-duty gearbox and bearing systems for continuous operation.
| Factor | Side Entry Mixer | Top Entry Mixer |

They create continuous circulation that maintains uniform temperature and prevents sediment accumulation.
They distribute heat evenly throughout the tank and reduce temperature gradients.
Yes. Continuous circulation helps maintain additive dispersion during storage.
Yes. They are specifically designed for heated storage and high-viscosity fluids.
KEHENG provides tank circulation analysis, mixer selection support, energy optimization studies, impeller design, installation guidance, and commissioning support for bitumen and asphalt storage applications.
