Drying production line
The drying production line is a complete set of equipment for heat drying and screening sand or other bulk materials. It consists of the following parts: wet sand hopper, belt feeder, belt conveyor, burning chamber, rotary dryer (three-cylinder dryer, single-cylinder dryer), cyclone, pulse dust collector, draught fan, vibrating screen, and electronic control system.
The sand is fed into the wet sand hopper by the loader, and be conveyed to the inlet of the dryer through the belt feeder and conveyor, and then enters the rotary dryer. The burner provides the drying heat source, and the dried sand is sent to the vibrating screen by the belt conveyor for screening (usually the mesh size is 0.63, 1.2 and 2.0mm, the specific mesh size is selected and determined according to actual needs). During the drying process, the draught fan, cyclone, pulse dust collector and pipeline constitute the dust removal system of the production line, and the whole line is clean and tidy!
Because sand is the most commonly used raw material for dry mortars, the drying production line is often used in conjunction with the dry mortar production line.
Wet sand hopper
The wet sand hopper is used to receive and store the wet sand to be dried. The volume (standard capacity is 5T) can be customized according to user needs. The outlet at the bottom of the sand hopper is connected to a belt feeder. The structure is compact and reasonable, strong and durable.
The belt feeder is the key equipment for evenly feeding the wet sand into the dryer, and the drying effect can be guaranteed only by feeding the material evenly. The feeder is equipped with a variable frequency speed regulating motor, and the feeding speed can be adjusted arbitrarily to achieve the best drying effect. It adopts skirt conveyor belt to prevent material leakage.
Belt conveyor
Belt conveyor is used to send the wet sand to the dryer, and convey the dried sand to the vibrating screen or any designated position. We use nylon conveyor belt, which has high strength, impact resistance and long life.
Burner
Depending on the user's fuel, we can provide gas burners, light oil burners, heavy oil burners, pulverized coal burners, and biomass pellet burner, etc.
Provide space for fuel combustion, the end of the chamber is provided with an air inlet and an air regulating valve, and the interior is built with refractory cement and bricks, and the temperature in the burning chamber can reach up to 1200 ℃. Its structure is exquisite and reasonable, and it is closely combined with the dryer cylinder to provide sufficient heat source for the dryer.
Three cylinder rotary dryer
The three cylinder rotary dryer is an efficient and energy-saving product improved on the basis of the single-cylinder rotary dryer.
There is a three-layer drum structure in the cylinder, which can make the material reciprocate three times in the cylinder, so that it can obtain sufficient heat exchange, greatly improve the heat utilization rate and reduce power consumption.
The material enters the dryer inner drum of the dryer from the feeding device to realize downstream drying. The material is continuously lifted up and scattered by the inner lifting plate and travels in a spiral shape to realize heat exchange, while the material moves to the other end of the inner drum then enters the middle drum, and the material is continuously and repeatedly raised in the middle drum, in the way of two steps forward and one step backward, the material in the middle drum fully absorbs the heat emitted by the inner drum and absorbs the heat of the middle drum at the same time, the drying time is prolonged, and the material reaches the best drying state at this time. The material travels to the other end of the middle drum and then falls into the outer drum. The material travels in a rectangular multi-loop way in the outer drum. The material that achieves the drying effect quickly travels and discharges the drum under the action of hot air, and the wet material that has not reached the drying effect cannot travel quickly due to its own weight, and the material is fully dried in this rectangular lifting plates, thereby completing the drying purpose.
Advantages
1. The three cylinder structure of the drying drum increases the contact area between the wet material and the hot air, which reduces the drying time by 48-80% compared with the traditional solution, and the moisture evaporation rate can reach 120-180 kg/m3, and the fuel consumption is reduced by 48-80%. The consumption is 6-8 kg/ton.
2. The drying of the material is not only carried out by the hot air flow, but also carried out by the infrared radiation of the heated metal inside, which improves the heat utilization rate of the whole dryer.
3. The overall size of the dryer is reduced by more than 30% compared to ordinary single-cylinder dryers, thereby reducing external heat loss.
4. The thermal efficiency of the self-insulating dryer is as high as 80% (compared to only 35% for the ordinary rotary dryer), and the thermal efficiency is 45% higher.
5. Due to the compact installation, the floor space is reduced by 50% and the infrastructure cost is reduced by 60%.
6. The temperature of the finished product after drying is about 60-70 degrees, so that it does not need an additional cooler for cooling.
7. The exhaust temperature is low, and the life of the dust filter bag is extended by 2 times.
8. The desired final humidity can be easily adjusted according to user requirements.

Note
1. These parameters are calculated based on the initial sand moisture content: 10-15%, and the humidity after drying is less than 1%
2. The temperature at the inlet of the dryer is 650-750 degrees.
3. The length and diameter of the dryer can be changed according to customer requirements.
Cyclone
It is connected to the air outlet of the dryer end cover through a pipeline, and is also the first dust removal device for the hot flue gas inside the dryer. There are a variety of structures such as single cyclone and double cyclone group could be chosen.
It is another dust removal equipment in the drying line. Its internal multi-group filter bag structure and pulse jet design can effectively filter and collect dust in the dust-laden air, so that the dust content of the exhaust air is less than 50mg/m³, ensuring that it meets the environmental protection requirements. According to the needs, we have dozens of models such as DMC32, DMC64, DMC112 for selection.
Draught fan
The draught fan is connected to the impulse dust collector, which is used to extract the hot flue gas in the dryer, and it is also the power source for the gas flow of the entire drying line.
After drying, the finished sand (water content is generally below 0.5%) enters the vibrating screen, which can be sieved into different particle sizes and discharged from the respective discharge ports according to the requirements. Usually, the size of the screen mesh is 0.63mm, 1.2mm and 2.0mm, the specific mesh size is selected and determined according to actual needs.
All steel screen frame, unique screen reinforcement technology, easy to replace the screen.
Contains rubber elastic balls, which can automatically clear the screen blockage.
Multiple reinforcing ribs, more robust and reliable
Electronic control system
The entire production line is controlled in an integrated manner, with a visual operation interface, through frequency conversion to adjust the speed of the feed and drying drum rotates, intelligently control the burner, and realize intelligent temperature control and other functions.
