Dry Powder Mortar Dryers These innovations bring unparalleled advantages
Traditionally, the single-cylinder type sand washing and drying machine is used. Due to the small wet resistance coefficient, the low heat transfer efficiency, and the high external dissipation, the cost per ton of dry powder produced is much higher than the market price. Investors are reluctant to engage in this area, and special washing sand dryers can solve this problem. The special washing sand dryer breaks the traditional drying concept. On the basis of inheriting the traditional drying concept, it is innovated and improved, and has unparalleled advantages.
1. Due to the accumulation of backlog for a long time, there are large lumps. If the large lumps enter the cylinder and are not crushed in time, it is easy to cause blockage or unclean water drying. The drum is equipped with a device for dispersing and automatic uniform distribution, which solves this difficulty.
Second, the particle size is relatively fine, and the drying process is negative pressure drying. If the air pressure is too small, the heat source cannot pass through quickly, and the output cannot be increased. If the wind pressure is too large, the undried fine powder will be brought into the finished product, so the stability of the final moisture content of the material cannot be guaranteed. Our company has designed a feeding device inside the barrel of the washing sand dryer, which completely solves the above problems.

3. When selecting the type, it is necessary to explain the water content and final water content, the loss on ignition of ash, the content ratio of primary ash, the content ratio of secondary ash, and whether to use a sorting machine.
Uncover the structure and principle of the sand washing and drying machine equipment, let all users know the structure and working principle of the sand washing and drying machine, and how to reach a new level for their drying business.
The main body rotates horizontally on the four supporting wheels 5 at both ends through the wheel belts 4 at both ends, and the feed end of the cylinder body is provided with fuel, steam, coal and other hot blast stove devices. The discharge end is provided with a dust cover and an automatic feeding device. The dust cover is connected to the dust collector through a pipeline, and the dust removal equipment, feeding equipment and conveying equipment can be designed separately according to the user's process conditions and requirements. The drying process of the sleeve-type three-cylinder washing sand dryer is realized in this way. The dried material is fed into the inner cylinder of the washing sand dryer from the feeding end, and the material enters the inner cylinder through the spiral guide plate of the inner cylinder. There are many spiral lifting plates inside the inner cylinder. The material is continuously lifted by the lifting plate through the rotation of the cylinder body and moves longitudinally. The material reaches the left end of the inner cylinder and falls into the middle cylinder due to its own weight. Under the action of the rotation of the cylinder, the material is pushed back to the middle cylinder, and under the action of the middle cylinder lifting plate, the material moves to the right until the right end of the middle cylinder, and the material falls into the outer cylinder under the action of its own weight. In the same way, the material is folded back and moved to the left under the action of the outer cylinder screw lifting plate until the left end of the outer cylinder. Under the action of blocking the outer guide cone, it falls into the barrel of the discharge end.
In the 1, 2, 3, and three concentric cylinders of the main body of the three-cylinder dryer, there are different numbers and different angles of curved surface helical lifting plates, and the end of each cylinder is provided with a guide plate. The main body of the sleeve-type short-drum sand washing and drying machine drives the two transmission rollers at both ends through two reduction motors, so that the wheel belt rotates around the center. The wet material of the sand washing and drying machine is fed into the feeding end of the inner cylinder 3 through the feeding device and the feeding pipe, and the wet material is quickly pushed to the screw lifting plate through the spiral guide plate. The spiral lifting plate in each cylinder makes the material to be lifted, and at the same time, it continuously rolls, scatters and moves longitudinally to the discharge end.
