2024-07-11Dust Removal Method of Sand Dryer
Dust removal method: Sand dryer is required to regularly clean the dust in the dust collector, do not underestimate the dust cleaning work, it is a technical work, non-professionals are generally not allowed to operate, but for the relevant operators of sand dryer, sand dryer supporting dust collector cleaning method is needed to understand and master. 1. Mechanical cleaning method: This method is a very simple one when cleaning the dust collector of the sand dryer. 2. Acoustic cleaning method: The use of acoustic waves to make the filter bag of the sand dryer supporting the dust collector vibrate to achieve the purpose of cleaning. 3. Pulse cleaning method: The use of pulsation will be the sand dryer supporting dust filter bag dust shock 4. Reverse air cleaning method: the gas and the dust on the filter bag show a relative state of motion.

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...

2024-07-04What are the Advantages of the Non-gravity Twin Shaft Paddle Mixer?
Non-gravity twin shaft paddle mixer is widely used in dry mortar, chemical, pesticide, detergent, pigment food, monosodium glutamate, milk powder, salt, feed, chemicals, ceramics, plastics, rubber additives and other dry materials and mixing. How it works: The horizontal cylinder of the non-gravity twin shaft paddle mixer is equipped with a double-axis rotating reverse blade, which turns the material along the axial and radial circulation at a certain Angle, so that the material is quickly mixed evenly; In order to reduce the replacement cost of the wearing parts of the equipment, the blade blade can be made into two pieces, and a movable small blade is placed on the blade base to directly replace the worn small blade, which is economical and fast; The discharge form is generally pneumatic (manual) flap valve, arc valve is tightly embedded in the cylinder, flush with the inner wall of the cylinder, no material accumulation and mixing dead Angle phenomenon; The standard type has the difference of opening the door and opening the door to the side of the cylinder, and the material is clean and fast, and the residue is less. Performance characteristics: The rotation speed of the shaft driven by the reducer and...
