Bulk Cement Tank Transport Semi-trailer

Bulk cement tanker, also known as cement tanker or powder material truck. A car with enclosed cargo compartments and automatic unloading devices for transporting bulk cement. Mainly used for cement factories, cement warehouses, and large construction sites, it can save a lot of packaging materials and loading and unloading labor. There are three types of bulk cement trucks, which are introduced:
① Gravity ash unloading truck: The earliest bulk cement truck to appear. It is made by installing a sealed cargo compartment top cover on an ordinary dump truck. When unloading, the cargo compartment tilts up and the cement is automatically unloaded by gravity. This ash unloading method can only unload cement to a position lower than the carriage, and the cement will fly during unloading, resulting in a large area of material falling.
② Mechanical ash unloading trucks: They began to be used in the 1950s. It uses a screw conveyor installed on a car to unload ash, adjusts the height of the screw conveyor, and can unload cement to different heights, reducing cement flying. However, the ash unloading machine components are prone to wear and tear due to direct pushing of cement.
③ Pneumatic ash unloading truck: It appeared in the 1960s and is relatively easy to use. The maximum load capacity of this car is nearly a hundred tons. Its cargo compartment is a tank type container, standing or lying diagonally on the car frame. Horizontal tanks have a lower center of gravity and are widely used for stable driving. The tank body is welded with steel or aluminum plates, and can also be made of fiberglass. The upper part of the tank has one or more ash filling openings along its length, making it easy to fill the entire tank. The ash loading port can also serve as an entrance and exit for maintenance personnel. The bottom of the tank is equipped with a cement fluidization device. The car is equipped with an air compressor for ash unloading. When unloading ash, compressed air is sent into the tank from the bottom, and is divided into fine streams through the breathable layer of the cement fluidization device. The cement is evenly filled to form an air cement mixture, and under the pressure difference between the inside and outside of the container, the cement is discharged along the discharge pipe. The pneumatic ash discharge method has the advantages of fast ash discharge, less dust flying, and the ability to discharge materials from any height and distance using flexible long discharge pipes. It can also be used for outdoor operations in windy and rainy days.
