1. Gravity unloading truck: The earliest bulk cement truck. It is made up of a common dump truck with a closed cargo compartment top cover. When the cargo is unloaded, the cargo compartment is tilted and the cement is automatically discharged by gravity. This method of unloading can only discharge the cement to a position lower than the compartment, and the cement is flying when the cargo is unloaded, and the blanking area is large.
2. Mechanical unloading truck: It was used in the 1950s. It uses the screw conveyor installed on the truck to unload the ash, adjusts the height of the screw conveyor, can discharge the cement to different heights, and can reduce the cement flying, but the ash remover is easy to wear due to the direct push of cement.
3. Pneumatic unloading truck: Appeared in the 60s, it is relatively easy to use. At present, the maximum load capacity of this type of truck is nearly 100 tons. Its cargo compartment is a tank container, standing or lying on the frame of the car. The horizontal tank has a lower center of gravity, and the truck is stable and has many applications. The can body is welded with a steel plate or an aluminum plate, and can also be made of glass steel. The upper part of the tank has one or more ash openings along the length of the tank to facilitate filling the full tank. The ash port can double as the entrance and exit of the maintenance personnel.
