Principle of mineral powder dryer

1. dissimilarity! There is no strength in the mineral powder itself, but when the mineral powder and cement are mixed together, the silica in the mineral powder will react with the alkali in the cement to form ettringite, which will have a strength effect. The composition of mineral powder is relatively active and can participate in a lot of hydration reactions. Therefore, mineral powder is divided into three grades. S105 S95 S75 mineral powder and cement are replaced by the same amount. To put it bluntly, if you mix 90 kg of mineral powder into each concrete, you can mix 90 kg less cement. But fly ash is different. Fly ash has no activity and basically does not participate in the hydration reaction of cement. The good point is to improve the workability and rece the hydration heat. The hard point is to alterate and rece the cost. Fly ash is replaced by excessive amount.

2. Dryer is a kind of washing machine, which is usually used to remove moisture from clothing and other textiles after washing and dehydration. Most dryers include a rotating drum, the inner drum is driven by a belt, and there is hot air around the drum to evaporate water. The drying cylinder adopts the principle of positive and negative rotation of the drum to achieve the non winding effect of drying articles
working principle
power is generated by electric power, diesel power, wind power, inflammable materials, etc., which is heated by ambient air and transported to the surrounding area for dehumidification treatment at appropriate temperature
characteristics
1. The drying intensity is high, because the material is highly dispersed in the air flow, the whole surface of the particles is the effective area for drying
2. Short drying time
3. The air flow dryer is simple in structure, small in floor area, and easy to build and maintain
4. Large capacity and high thermal efficiency. When the unbound water is dried, the thermal efficiency can reach 60%
5. The dryer realizes "zero horizontal thrust", greatly reces the wear of the retaining roller, and the cylinder runs smoothly and reliably
6. The dryer adopts "self-aligning supporting roller device", which makes the supporting roller and rolling ring always in linear contact, thus greatly recing the wear and power loss;

3.

The drying principle of the dryer is to generate power through electricity, diesel power, wind power, flammable material power, etc., and use the ambient air to heat, transport to the surrounding, and then reach the appropriate temperature for dehumidification

wet materials are sent to the hopper by belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipe through the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line

with the rotation of the cylinder, the material moves to the lower end under the action of gravity. When the wet material moves forward in the cylinder, it is directly or indirectly heated by the heat carrier to dry the wet material, and then sent out by belt conveyor or screw conveyor at the discharge end

the inner wall of the cylinder is equipped with a plate, which is used to and scatter the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the material forward. The heat carrier is generally divided into hot air, flue gas and so on

After the heat carrier passes through the dryer, a cyclone is usually needed to capture the materials in the gas. If it is necessary to further rece the st content of tail gas, it should be discharged after the bag filter or wet filter

extended data

dryer is mainly used for conveying materials and other media, including stainless steel, carbon steel and so on. The main application theory is direct current hot gas drying

cooling section: the sudden cooling of high temperature objects will make the materials denatured. The main purpose of the cooling section is to graally cool, which is mainly reflected in the length of the dryer. Next segment: the material is finally separated from the equipment from the discharge port

Due to the high dispersion of the material in the air flow, the whole surface of the particles is the effective area for drying. The drying time is short. The air dryer has the advantages of simple structure, small floor area, easy construction and maintenance

large capacity and high thermal efficiency. When the unbound water is dried, the thermal efficiency can reach 60%. The dryer realizes "zero horizontal thrust", greatly reces the wear of the retaining roller, and the cylinder runs smoothly and reliably; The dryer adopts "self-aligning supporting roller device", which makes the supporting roller and rolling ring in linear contact forever, thus greatly recing the wear and power loss

4. Working principle of slag dryer: slag is delivered to the hopper by belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe of the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the mine dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line, and the material is added from the higher end, The heat carrier enters from the low end and contacts with the material in a counter current. Some heat carriers and the material flow into the cylinder in parallel. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. In the process of moving forward in the cylinder, the wet material is directly or indirectly supplied by the heat carrier, so that the wet material can be dried, and then sent out through the belt conveyor or screw conveyor at the discharge end, The inner wall of the slag dryer cylinder is equipped with a plate, which is used to and scatter the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the material forward. After the heat carrier passes through the dryer, it generally needs a cyclone to capture the material in the gas (the heat carrier is generally divided into hot air, flue gas, etc.).

Introction: in instrial proction, we often use the dryer. The use of the dryer can not only improve the quality of our procts, but also improve our proction efficiency, so as to bring huge economic benefits to our enterprises. However, how much do you know about the working principle of the dryer? We only use dryers, but we don't know how they work. Is that a pity? So want to understand the working principle of the dryer friends come to understand it

working principle of dryer: the dryer is mainly powered by electricity, diesel power, wind power, inflammable material power, etc., which is heated by ambient air and transported to the surrounding area to reach the appropriate temperature for dehumidification treatment

the specific working process of the dryer is as follows: wet materials are sent to the hopper by belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipe through the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line

the material is added from the higher end, the heat carrier enters from the low end and contacts with the material in a counter current, and the heat carrier and the material flow into the cylinder in parallel. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. When the wet material moves forward in the cylinder, it is directly or indirectly heated by the heat carrier to dry the wet material, and then sent out by belt conveyor or screw conveyor at the discharge end. The inner wall of the cylinder is equipped with a board, which is used to and scatter the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the material forward

heat carriers are generally divided into hot air and flue gas. After the heat carrier passes through the dryer, the cyclone st collector is generally required to capture the materials in the gas. If it is necessary to further rece the st content of tail gas, it should be discharged after the bag filter or wet filter. Heat pump dryer (also known as heat pump dryer) is a professional device based on the principle of heat pump, additional air supply system and heat dissipation system. Heat pump dryer is a new type of high efficiency and energy saving dryer

the above is Xiaobian's introction about the working principle of the dryer today. As the users of the dryer, we understand the working principle of the dryer, not only can we use it better, but also can understand it when our dryer has problems, And will not blindly do not know anything, so that when the professional maintenance was pit money. The above small and medium-sized editor has introced to you the working principle of the dryer, I hope you can help

6. The dryer is also a large oven,
drying must have a heat source, heating methods are: electric heating, oil heating, and heating with other fuels
in order to heat the dried articles evenly, there should be a hot air circulation system in the dryer
in order to maintain the specified drying temperature of the dried articles, there should be a temperature control system in the dryer.

7. The dryer is a kind of washing machine, which is usually used to remove moisture from clothing and other textiles after washing. Most dryers include a rotating drum, the inner drum is driven by a belt, and there is hot air around the drum to evaporate water

When the weather is fine, many of us like to hang out our wet clothes, but if it's rainy or cold, it's better to dry them - so that you can put on clean, warm clothes without clothes. You need to know which clothes need to be dried and how to use the machine. Please pay attention to the following tips

dryer is a kind of washing machinery, which is generally used to remove moisture in clothing and other textiles after washing and dehydration

most clothes dryers include a rotating drum, the inner drum is driven by a belt, and there is hot air around the drum to evaporate water. Clothes drying cylinder adopts the principle of positive and negative rotation of roller to achieve the non winding effect of clothes drying

the principle of the dryer is to take away the moisture with hot air

the air first enters the upper heater, which heats the air to 70-80 degrees, and then the air enters the dryer to heat the clothes and take away the moisture by the way, and then enters the lower filter screen, which filters the impurities such as fluff in the air, and then enters the fan, Exhaust through the exhaust fan

the main principle is blowing hot air, cooling with cold water to complete the drying! It's impossible for you to do it yourself. Even if it's similar, the cost will be much higher than buying a ready-made one
