What is a bulk cement tank trailers?

Bulk cement tank trailers is a tank car used to transport bulk powders such as flour, cement and chemical powders and other similar products. The utility model is composed of a combined chassis structure, with a tank car, a pipeline system and a plurality of unloading devices. The design considers the safe loading and transportation of bulk powder products.

The particle size of products transported by bulk cement tank trailer is less than 0.1mm. It is usually used in the cement manufacturing industry to transport cement to the construction site and warehouse. Bulk cement tank trailers have a huge advantage: the cost of loading and unloading products is greatly reduced.

Working principle:

In order to load and discharge products from tank cars, the fluidization principle is adopted. This is why the bulk cement tank trailers makes the powder flow like a liquid. The cost of the process can be quickly and efficiently converted into powder.

Using the “liquid” properties of powder

Powder will acquire some liquid properties when exposed to gas to some extent. In the fluidization process, the process is similar to the liquefaction process. In the liquefaction process, the granular material changes from its initial static solid state to dynamic fluid state. This usually occurs when the gas passes through the granular material.

The gas is introduced through the bottom used to transport solid particles, which moves upward through the bed and enters the gap between particles. When the gas velocity is low, the aerodynamic resistance on the particles is also low, which keeps the bed in a fixed state.

During high-speed operation, aerodynamic resistance is opposite to gravity and counteracts each other, causing the bed volume to expand, and the particles begin to pull away from each other. As the speed continues to increase, when the upward resistance is the same as the downward gravity, it will reach a critical value.

Fluidization:

Here, the particles will now be in a suspended position in the fluid. At this time, the bed is called fluidization. As the fluid velocity increases further, the bulk density of a given trailer bed begins to show fluid behavior. With the passage of time and the increase of fluid velocity, the bulk density of the trailer bed will continue to decrease, resulting in more severe fluidization. As this process continues, the particles will no longer form a bed, but move upward with the air flow. After the bed is completely fluidized, the solid particles will begin to flow like a fluid.

Summary

Bulk cement tank trailer is a very useful tanker customized for powder products. It is conducive to the efficient transportation of materials such as cement, flour, chemical powder and many similar products. This is the safest, quickest and effective way to transport powder products, with the least or no residual products on it.
