2024-07-09Development of Dry Mortar Production Line
The development of dry mortar production line in China is mainly concentrated in the following points: 1. Dry mortar varieties using industrial wastes and local materials as the main raw materials. The utilization of fly ash, slag, waste stone powder, oil refining waste, bentonite, etc., but can not reduce the cost of dry mortar, mortar performance, and is conducive to protecting the environment and saving resources. 2. Develop new varieties. Only the development of mortar varieties that meet the needs of the market can make its scope of use unrestricted and create good conditions for its smooth promotion. With the emergence of mortar, special mortar not only drives the development of dry mortar, but also creates conditions for promoting the development of other industries. 3. Develop their own production process. At present, the production process of dry mortar is not mature enough in China, and the production lines of general production enterprises are introduced from abroad, and their investment in a production line is 20-30 million yuan, and the price is expensive. Only by developing a production process in line with China’s national conditions can we create conditions for the construction of dry mortar enterprises, which not only reduces the...

2024-07-08Factors affecting the production efficiency of Three-Return Dryer:
There are many factors affecting the production efficiency of the three-return dryer, many such as the environmental impact of mechanical use, the use of components and the state of wear, etc., will reduce the use efficiency of the machine. During the work of the three-way dryer, each part is in a high temperature state, when the mortar and mineral powder enter the drying cylinder for drying, there will be a lot of steam discharged at the exhaust hole, for drying materials we need to do logistics support in each link, because there will be materials in the drying did not dry, need to return to the oven drying. Three return dryer energy measures: 1. Reduce heat loss 2. Reduce evaporation load 3. Increase the hot air temperature 4. Waste cycle 5. Air flow direction control 6. Exhaust air volume control 7. Drying solvent control 8. Automatic control 9. Waste gas heat recovery 10. The impact of three-return dryer installation and use 11. Impact of ambient humidity

2024-07-08How to Reduce Noise in Triple Cylinder Drying Machine？
The three-return dryer and other dryers are medium and large machinery, and the three-return dryer produced by the old era and the undeveloped technology dryer manufacturers is noisy in the operation process. Now our country is advocating energy conservation and environmental protection, and the noise of the dryer also affects the lives of residents. In today’s advanced society, the noise problem of the three-trip dryer can be avoided, so how is it done? For you to analyze how the three-return dryer is able to reduce the noise problem: 1. Add sound insulation cover. The whole three-pass dryer is closed by using steel structure skeleton, thin steel plate as shell, internal damping layer and filling with ultra-fine glass wool or other sound absorbing materials. Because the three-return dryer generates a lot of heat when it is running, attention must be paid to solving the heat dissipation in the cover and facilitating equipment maintenance. 2. With rubber liner instead of manganese steel liner, the noise level can be reduced by 9dB(A), and the spectrum characteristics also have high frequency to low frequency. 3. Set the elastic layer. Lay a heat-resistant soft rubber pad between the inner surface of the three-return dryer drum...

2024-07-05Which is more Advanced, Three Drum Dryer or Triple Cylinder Drying Machine?
The two have similarities: 1. All industrial dryers are used to dry sand and other materials with good fluidity. 2. All are composed of three cylinders, and the material goes back and forth in the dryer three times to achieve full drying of the material. 3. Small floor area, high heat utilization rate, energy saving and environmental protection, dry thoroughly. The difference between the two: 1. Generally speaking, the three-return dryer is short in length and large in diameter, while the three-cylinder dryer is slightly longer in length and relatively small in diameter. 2. The three-cylinder dryer has no taper from the appearance, and is slightly longer, while the three-return dryer has a slight taper from the outside, and is thicker and shorter. 3. The three cylinders inside the three-return dryer have a certain taper, and the three cylinders inside the three-cylinder dryer have no taper. 4. Generally speaking, the length of the three-cylinder dryer can be designed to be longer, and the three-return dryer is designed to be shorter. Which of the two dries better? We suggest that it is better to use a three-cylinder dryer or multiple three-return dryers for drying materials above 50 tons per hour; The...

2024-07-05What factors should be considered when using Sand Dryer?
1. Drying temperature: According to different materials, in the case of drying quality, try to choose a higher drying temperature to speed up the drying speed. 2. Humidity: Materials have different humidity. 3. Wind speed of hot air medium: The speed of hot air medium in the drying room is related to the drying speed, material shape and material characteristics. 4. Drying speed and drying method selection: drying should be controlled under technical parameters, such as temperature, humidity and wind speed, in order to achieve the retention of raw materials during the drying process. 5. Material placement: Stack thickness and placement method affect the drying speed. Reasonable control of pile thickness, increase heat exchange area and ventilation, speed up the drying speed. 6. Mixing and drying of different varieties: in principle, when raw materials are dried, a single variety is needed, and it is impossible to mix and dry together.
