How does the pneumatic cement tank trailer work?

Panda Mech • 2020-10-07 11:39:42

The dry bulk cement tanker trailer used for transporting cement is a bulk powder transport vehicle made of a combined specially designed chassis, pneumatic piping system, tanker, and discharging units.

This design is specially made for the safe transportation of bulk cement commodities, lime powder, coal powder, and any other dry powder material that has a particle diameter of less than 0.1mm.

Its common application and use are in the cement manufacturing factory, construction sites, and the cement warehouse. With the use of this type of trailer, packaging and discharging costs are greatly reduced.


1. Why use a cement tank trailer to transport dry bulk cement?

Simple and Convenient

It can transport a lot of cement at once. Most importantly, it ensures that the quality of the cement in transit is safe from any dampening.

No much of packaging and unpacking is needed with the use of a cement tanker trailer. The process of loading and unloading cement from the tanker is simplified through the fluidization process.

Effective and Reliable Delivery Speed

The transportation of high amounts of cement can be done at reliable speeds. The trailer offers an effective means of transportation taking up huge volumes of cement at ago.

This saves a lot on transportation costs. Everything is designed to ensure efficient transportation and delivery of large volumes of cement efficiently and in the shortest time possible.

High Load Carrying Capacity

The cement bulker trailer takes up to 95 cubic meter capacity per set.

It provides a perfect solution for the transportation of high volumes of cement especially for heavy construction projects unlike using traditional cement transportation means that may not be sufficient for handling large projects.

3. What is the fluidization principle?

The cement tank trailer’s working principle is based on the Fluidization principle.

When the mixture of gas and powder reaches a certain proportion, the powders will have some liquid properties hence attaining fluidity.

Fluidization is a process comparable to liquefication in which granular materials get converted to dynamic fluid-like states from their original static solid nature. This normally happens when a gas or a liquid is passed up and through granular material.

When gas flow gets introduced via the bottom of the bed carrying solid particles, it tends to move in an upward manner via the bed through the empty spaces existing in between the material particles.

What is the fluidization principle

When the gas velocities are low, the aerodynamic drag on each of the particles is also low hence the bed is kept in a fixed state.

At high velocities, the aerodynamic drag forces will start to counteract the gravitational forces and make the bed expand volumetrically as the powder particles begin to pull away from one another.

With a continued increase of the velocity, a critical value will be reached where the upward drag forces equal the downward forces of gravity.

At such a point, the particles will get suspended inside the fluid. This is when the bed is considered to be fluidized and will show such behavior. A further increase in the fluid velocity, the bulk density of the trailer bed will show fluidic behavior.

If the gas velocity continues to increase further, the bulk density of your bed will keep decreasing and the fluidization gets more violent.

This will continue to a point where the particles no longer form a bed and are taken upwards through the flow of the gas. When the bed is fluidized, solid particles on it will start to flow like a fluid.
