With the continuous development of the domestic freight industry, ordinary road cargo transportation tends to be saturated and competition is becoming more and more fierce. Many special riders are optimistic about the professional transportation industry such as powder and grain material transportation vehicles. The advantages and disadvantages and scope of application provide reference for everyone to purchase powdered material vehicles.
The pulverized material transporter is a special pulverized material transporter for transporting powder and granular materials. It can store and transport powdered and granular cargoes such as fly ash, cement, lime powder, ore powder, grain and other solids. , Uninstall the integrated operation. There are two types of discharge methods: pneumatic type and gravity type unloading. When pneumatic unloading, the goods can be transported to a certain distance or a certain height of the storage container.
The classification is different from different angles. At present, the classification is based on the transport medium and the tank structure. According to the transportation medium, it can be divided into bulk flour vehicles, bulk feed vehicles, bulk cement trucks, and dry mix mortar vehicles. According to the tank structure, it can be divided into horizontal powder material transport vehicle, vertical powder material transport vehicle, and lift type powder material transport vehicle.

Through the comparison of the advantages and disadvantages of the powder material vehicles of the three different tank layout structures of the horizontal powder material transport vehicle, the vertical powder material transport vehicle, and the lift type powder material transport vehicle, combining the characteristics of the transport materials, To select the appropriate powder material transporter.
First, the advantages and disadvantages of the horizontal powder material transporter
As the name implies, the horizontal powder material transportation vehicle is a horizontally placed tank body on a powder material transportation vehicle. The internal fluidized bed used for auxiliary unloading has a “V†shape. When the lower part of the fluidized bed is fed with compressed gas, the material starts flowing to the lowest point under the action of the fluidized bed and flows out through the discharge outlet to the reservoir. Material container.
Horizontal powder material transporter
advantage:
   1. The center of gravity of the vehicle is low and the driving is more stable;
2. The volume of the tank is large;
3, discharge faster: generally only one silo, the tank built-in pressure is short, discharge faster;
4, easy to operate at work.
Disadvantages: Only used for powder bulk transport with good fluidization properties.
Second, the advantages and disadvantages of the vertical powder material transporter
The tank structure of the vertical powder material transport vehicle consists of a plurality of inverted cones and a flat cylinder. The lower part of each cone is equipped with a fluidized bed and a large inclination angle, which ensures that the material contained in the tank can slide down to the fluidized bed at the bottom of the cone quickly and smoothly. When the compressed gas is introduced into the lower part of the fluidized bed, the material is passed through the discharge port to the designated storage container under the effect of the fluidized bed.
Vertical powder material transporter
advantage:
   1, the scope of shipment of a wide range of materials, powder and granular materials, granular materials, powder and aggregate materials can be. Granular materials can be pneumatically discharged, and bulk materials can be unloaded by gravity;
2, the remaining material rate is very low. The large inclination angle can effectively ensure that the material slides smoothly to the fluidized bed at the bottom of the cone, and the area of ​​the fluidized bed is small, so the remaining rate of the material in the tank is very low;
Disadvantages:
1. The center of gravity of the vehicle is slightly higher than that of the horizontal powder material transporter;
2. The unloading process takes slightly longer than the horizontal powder particle transporter of the same volume. Because the tank is generally a multi-warehouse structure, the gas pressure in the tank must be re-elevated to a certain value after each tank is unloaded, so that the next tank can be unloaded and the unloading time can be longer.
3. The manufacturing process of the vertical powder material transporter is more complicated than the horizontal powder material transporter, and the cost of the entire vehicle is higher.
Third, the advantages and disadvantages of lift-type powder material transport vehicle analysis
The tank structure of lift-type powder and grain material transportation vehicle is relatively simple. A hydraulic lifting cylinder is arranged at the front end of the tank body. A similar cone structure is welded on the tail of the cylinder body, and a fluidized bed is arranged at the bottom of the cone body. And unloading outlets.
Lifting type powder material transporter
   advantage:
1. The lift type pulverized material transporter is a single bin structure. When the can body is lifted, it is equivalent to a compartment of the vertical pulverized material transporter. Therefore, the unloading operation is simple and the unloading speed is higher than that of the horizontal powder. Granular material transport vehicles and vertical powder material transport vehicles should be fast;
2. The materials for the transportation of lift-type powder and grain material carriers are extremely wide. The powder, pellets, and block materials are all suitable. It can be pneumatically unloaded or gravity-discharged.
3, the fluidized bed area is very small, so the material remaining material is extremely low, almost negligible, because the remaining material is extremely low, so some high-end materials for food materials and high quality requirements, lift type powder material transport vehicle Has unparalleled advantages;
4. The internal structure of the tank body of the lift-type powder material transportation vehicle is relatively simple, and it is convenient to clean and disassemble the fluidized bed, and different materials can be easily exchanged to achieve the purpose of one tank;
Disadvantages:
1. The tank wall thickness is slightly thicker than that of the horizontal powder material transporter and the vertical powder material transporter;
2. Due to the addition of a hydraulic lifting system, the one-time investment cost of the vehicle is higher; the site and weather requirements are higher when working;
3, the site requirements are relatively high, to be flat, there must be sufficient height space, the work site can not be too much wind and so on.
Summary: Different types of pulverized material transport vehicles have different working conditions. At present, the most used domestic powder tank vehicles are horizontal tanks, which are mainly used in the cement transport industry. We believe that with the development of the transport market, Increasingly, the market share of the other two types of powder material carriers will continue to increase.
