Bitumen Pump Cavitation and Suction Problems: NPSH, Viscosity, Temperature and Layout

A bitumen pump can have the correct rated flow and differential pressure yet still perform poorly if the suction side of the system is badly designed. Symptoms such as unstable flow, abnormal noise, vibration, reduced capacity, high motor load or intermittent loss of discharge are often blamed on the pump itself. In reality, the problem may originate between the storage…

Bitumen Pump Flow Rate Calculation for Asphalt Plants

A bitumen pump is easy to underestimate when designing an asphalt mixing plant support system. The storage tank may be large enough and the bitumen may be at the correct operating temperature, yet the asphalt plant can still wait for binder if the transfer pump cannot deliver the required flow under real operating conditions. The correct pump should therefore not…

How Bitumen Melting Machines Improve Asphalt Production Efficiency

In modern road construction, the continuous supply of high-quality hot bitumen is essential for maintaining asphalt production efficiency. Bitumen is widely used as a binding material in asphalt plants, highways, airports, and infrastructure projects. However, because bitumen becomes solid or highly viscous at normal temperatures, heating and melting it efficiently has always been a key challenge. A bitumen melting…

Complete Guide to Bitumen Equipment for Asphalt Mixing Plants

Bitumen is one of the most important materials in modern road construction. From asphalt mixing plants to highway maintenance projects, the quality and stability of bitumen directly affect pavement performance and service life. To achieve reliable asphalt production, contractors need more than an asphalt mixing plant. A complete bitumen handling system includes storage, heating, melting, modification, transportation, and processing equipment…

How to Choose a Bitumen Drum Decanter: 7 Costly Selection Mistakes | Feiteng

How to Choose a Bitumen Drum Decanter: 7 Costly Selection Mistakes to Avoid When contractors and asphalt plant operators shop for a bitumen drum decanter, most of the conversation stops at two questions: self-heating or external thermal oil? and what’s the price? Those matter — but they are rarely where a decanter purchase goes wrong. After 15+ years building drum decanters and melting machines…

Common Causes of Bitumen Drum Decanter Blockage and How to Prevent Them

For many road construction contractors, drum-packed bitumen is still a practical material supply format. Steel drums are easy to transport, store, and handle at remote project sites. However, when solid bitumen needs to be melted, transferred, and supplied continuously to a storage tank or asphalt plant, blockage can become a serious operating problem. Blockage in a bitumen drum decanter is…

Why Mobile Polymer Modified Bitumen Plants Are Taking Over Highway Projects in 2026

The global push for durable, weather-resistant infrastructure has made Polymer Modified Bitumen (PMB) a strict requirement for modern highway and airport runway projects. However, for road construction contractors, sourcing high-quality PMB presents a significant logistical and financial challenge. Historically, contractors relied on massive, stationary bitumen modification facilities. Today, the industry is witnessing a massive shift towards Mobile Polymer Modified Bitumen…

Green Bitumen: How Electric Heating Technology is Reducing Emissions in Urban Road Projects

As global environmental regulations tighten, the road construction industry is facing unprecedented pressure to reduce its carbon footprint. In urban environments, where noise and air pollution are strictly monitored, traditional coal or diesel-fired bitumen heating systems are becoming obsolete. Enter Electric Bitumen Heating Technology—a silent, emission-free, and highly efficient alternative that is redefining the concept of “Green Bitumen.” The Urban…

No Boiler? No Problem: Why Contractors Are Switching to Electric Heating Bitumen Tanks

For decades, the standard method for heating and storing liquid asphalt has been the Thermal Oil Boiler system. It is powerful and efficient for massive asphalt batching plants. However, what if your project is in a strict urban emission control zone? What if your site footprint is too small to build a separate boiler room? Or what if you simply…

Stop Buying Pre-Mixed PMB: The Ultimate Guide to On-Site SBS Modified Bitumen Production

If you are running an Asphalt Batching Plant for a major highway project, you already know the high cost of Polymer Modified Bitumen (PMB), specifically SBS (Styrene-Butadiene-Styrene) modified asphalt. Many contractors choose to buy pre-mixed PMB from large refineries and transport it to the job site. However, this creates three massive problems: High Material Cost: You are paying a premium…
