What are the functions of the fluidization device installed on the cement bulk carrier?

The cement bulk carrier is mainly used for the bulk transportation of fly ash, cement, lime powder ore powder, granular alkali and other powder and dry materials with a particle diameter not greater than 0.1mm. It has been widely used in industry, agriculture, commerce, power plants, construction, etc. Application special vehicle.

The cement bulk carrier consists of a chassis and a special device for bulk transportation of powder particles. The chassis of the car is referred to as the chassis, and the special device is referred to as the body. Everyone knows the chassis. Here we will focus on the fluidization device in the body. The bodywork mainly includes four parts: additional transmission system, tank assembly, piping system, and accessories.


The tank can be divided into three cabins and double cabins according to the number of cabins. The shape of the tank is round, oval and square. The tank body is mainly composed of a head, a cylinder, a manhole cover and a fluidization device.

The common head adopts standard oval head, the main specifications are EH2300mm, EH2400mm, EH2500mm, EH2600mm, EH2700mm. Common head and cylinder materials are 16Mn, Q345, QST420, etc.

Introduction to the fluidization of powder particles

When the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/s for cement), the friction between the gas and the powder is equal to the weight of the powder, and the powder no longer depends on the flow. The bed supports, at this point they can move freely and flow from high to low, keeping the upper plane of the powder layer horizontal, similar to liquid properties.

If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called the fluidization of the powder. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to make the compressed air form a fine and uniform airflow into the powder layer to fluidize the powder.
