Powder conveying systems are an essential component of many industrial processes, providing a cost-effective and efficient way to transport bulk materials. These systems are used in a variety of applications, from the food and pharmaceutical industries to the chemical and manufacturing sectors. In this article, we will explore the applications and benefits of powder conveying systems, and the impact they have on modern industrial operations.

Types of Powder Conveying Systems

Powder conveying systems come in a variety of types, each with its own unique set of advantages and applications. Pneumatic conveying systems, for example, use air pressure to transport powders through pipes or ducts. This is a popular option for industries that require a clean and hygienic method of powder transport, such as the food and pharmaceutical sectors. Another common type of powder conveying system is the screw conveyor, which uses rotating screws to move materials along a trough or tube. This system is well-suited to handling abrasive or fragile materials, making it a popular choice for the chemical and mining industries. Other types of powder conveying systems include belt conveyors, bucket elevators, and vibrating conveyors, each offering their own unique benefits and applications.

Powder conveying systems are used in a wide range of industrial applications, playing a crucial role in the efficient and reliable transport of bulk materials. In the food industry, for example, these systems are used to move ingredients and powders between processing stages, ensuring a smooth and continuous production process. In the pharmaceutical sector, powder conveying systems are used to handle delicate and often hazardous materials, providing a safe and hygienic method of transport. Powder conveying systems are also widely used in the chemical and manufacturing industries, where they play a key role in the movement of raw materials and finished products. With their ability to handle a wide range of materials, including powders, granules, and bulk solids, these systems are an essential component of modern industrial operations.

The LZL-200-GS air classifier shapes powders and removes ultra-fine powders. The equipment is fed from the pneumatic butterfly valve of the material in the raw material silo and sent to the main engine, and the material in the main engine is sprayed and depolymerized through the Laval nozzle, and the depolymerized material is graded by the grading wheel to the next grading wheel for compulsory classification, and the coarse powder is discharged through the double manual butterfly valve at the bottom of the breaking up host; The fine powder is collected by cyclone, and the solid-gas separation adopts a pulse dust collector.

I.Equipment advantages

1. Activate and loosen materials, smooth flow of materials, and no coal blockage;
2. Compact structure and low installation height, which can greatly save infrastructure investment;
3. All components are designed with long life, which is basically maintenance-free;
4. The feeding amount is adjustable online, which can be controlled remotely or locally.
5. Small power, large amplitude, simple structure, short maintenance cycle;
6. Neutralization and blanking, the belt does not deviate;
7. It has the function of uniform feeding and warehouse material cut-off, and there is no need to set up another gate;
8. Good sealing performance, even when the amount of coal is large, there will be no coal leakage;
9. The dynamic load of the equipment is small, the impact force is relatively small, and there are no special requirements for the foundation;
10. The equipment runs smoothly and reliably, with low noise and long life.

II.How it works

1. The principle of sub-resonance is adopted, and the excitation force is large. According to the theory of vibration and practical experience, the operating point of the activation feeder is in the sub-resonance range. In this way, it not only takes advantage of the characteristics of the equipment near the resonance point of large excitation force, but also avoids the resonance point, so that the equipment works without resonance, and greatly reduces the loss of the equipment.

2. The opening is a large square opening to avoid arching. According to the characteristics of coal, the phenomenon of material arching has a great relationship with the minimum size of the flow section of the silo, and has a small relationship with the flow section. The activation feeder adopts a large square opening, which maximizes the size of the two unilateral sides of the square while increasing the cutting area.

3. Special activation block design, large activation area. The activation feeder adopts a special activation block design, which organically combines and separates the blanking part and the activation part, so that the activation area of the upper part of the feeder is large, and the activation can reach 3~4 meters above the feeder inlet, so as to ensure that the coal is not blocked within the height range, and the blanking part is not subject to the pressure of the silo material, so as to ensure that the activated material falls freely and smoothly.

4. The matching of the material quantity and the activation amount is reasonable to avoid the more vibrating and more solid the material. The relationship between the amount of blanking and the amount of activation is designed reasonably to ensure that the amount of blanking is greater than the amount of activation, and there will be no accumulation of activated materials at the discharge port due to untimely blanking, resulting in agglomeration, thereby blocking the channel.

I.How it works:

The air tank for mixing control is filled with clean compressed air (in line with the operating pressure): the suction (feeding) device feeds the material into the mixing silo; PLC can be programmed to control the control valve/pneumatic control valve, and send compressed air (through the mixing head) into the mixing silo in the form of intermittent pulses, and the powder in the silo presents a spiral upward flow state under the action of pulsating airflow, and is thrown up and dislocated and falls; After several pulsed processes, the materials in the mixing silo are homogenized in a few minutes.

The compressed air enters the silo through the nozzle of the mixing head in a pulsed way, the compressed air spirals up, the material is impacted by the spiral rising compressed air, and the compressed air spirals up and expands together, and the material settles down after the compressed air expands to a certain extent, and a pulse mixing process is completed. After a pause for a few seconds after the end of one pulse, the mixing of the second pulse is started, and the pulsed compressed air drives the material to flip and roll (at the same time, there is diffusion mixing, convection mixing or mobile mixing, in which convection mixing or mobile mixing plays a major role) until the material is mixed evenly.

By continuously comparing the set value with the actual weight of the material conveyed by the screw, the speed of the steady flow spiral is constantly adjusted. As a result, the material flow is always stable at the set value.

I.How it works

The operator places the bag on the stand and pushes it into the grid. Then, the operator cuts a vertical opening in the bag, and dumps the shake bag to empty it, and the material falls into the hopper by power, and can be connected with the conveying unit equipment through the conveying pipe at the bottom, and the material is output to the specified position. The built-in induced air dust collector collects dust from the dust produced during the bag emptying process. The filter is cleaned by a reverse compressed air jet, and the cleaned dust falls back into the hopper for continuous feeding.

Vacuum feeder is a kind of dust-free closed pipeline conveying equipment that uses vacuum suction to transport particles and powdery materials, and uses the air pressure difference between vacuum and environmental space to form gas flow in the pipeline and drive the movement of powdery materials, so as to complete the transportation of powder. The foreign vacuum technology introduced by China has been continuously improved and improved, and is now widely used in chemical, pharmaceutical, food, metallurgy, building materials, agricultural and sideline industries and other light and heavy industries.

I.How it works

A vacuum generator or vacuum pump is used to generate a vacuum, and the negative pressure generated by the vacuum sucks the material from the inlet. The air is then separated from the material in the filter bin of the separator vessel. The material falls automatically due to gravity and is collected in the silo. Our cyclones prevent fine powders from entering the filter to improve the efficiency of the filter. When the silo is full of material, the vacuum pump automatically shuts down, and the pressure in the conveying equipment reaches equilibrium. The discharge valve is opened, and the material flows out through the discharge port and falls directly into the storage container. When discharging, the filter element is automatically cleaned by a back-blowing air bag. If the material is more viscous, we can install a special vibrator to assist in discharging. At the end of the blanking, the discharge compartment is automatically closed, and the whole conveying process is started again.

II.Equipment features:

When cleaning, the design of the clamps between the various modules of the equipment allows the conveyor to be easily removed and installed. The equipment does not have gaps and dead corners that are easy to accumulate materials.
2. Fluidization device: The fluidizer is to produce a layer of air mold between the material and the inner wall of the conveyor silo, through which the air film can effectively help the flow of materials with poor fluidity, which not only prevents the material from bridging, but also improves the unloading efficiency. The fluidizer material is sintered polyethylene, which meets the requirements of FAD.
3. Back-blowing system: built-in one-to-one back-blowing airbag, pulsed gas back-blowing, each cycle can efficiently clean the filter, making the equipment performance more stable.
