Rotary Dryer Applicable Materials

Rotary Dryer is often used to dry various non-flammable and non-explosive ores, such as river sand, copper ore, pyrrhotite, hematite, limonite, molybdenum ore, gold ore, quartz stone, iron ore, limestone , clay, etc.

Structure of Rotary Dryer

Rotary Dryer is mainly composed of rotating body, lifting plate, transmission device, support device and sealing ring, etc. It adopts a new type of lifting plate device, which has many functions such as guiding, equalizing flow and lifting material, which can make the material dry during drying. The radial section of the machine is uniformly distributed, and the material curtain becomes a thin, uniform and full state, which is completely in contact with the hot air flow to achieve the purpose of making full use of thermal energy.

• Rotary Dryer is used to convey materials and other media, and the materials are stainless steel, carbon steel and so on.
• The Rotary Dryer mainly passes the heated gas into the container through the fan, and has achieved the drying effect. The main application theory is the direct current hot air drying.
• Cooling section: The sudden cooling of high-temperature objects will degenerate the material. The main purpose of the cooling section is to gradually cool down, which is mainly reflected in the length of the dryer.
• The next segment: The material is finally removed from the device from the discharge port.

How Rotary Dryer Works

Power is generated by electricity, diesel power, wind power, flammable material power, etc., and the ambient air is heated, transported to the surrounding area of ??the tunnel, and then reaches an appropriate temperature for dehumidification treatment. The specific process is as follows: the wet material is sent to the hopper by the belt conveyor or the bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline 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. The material is added from the higher end, the heat carrier enters from the low end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly supplied by the heat carrier, so that the wet material is dried, and then sent out through a belt conveyor or a screw conveyor at the discharge end. A copy board is installed on the inner wall of the cylinder, and its function is to copy and sprinkle 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 advancement of the material. Heating medium is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should also be discharged after passing through a bag filter or a wet filter.

How to Pick a Rotary Dryer

• When purchasing a Rotary Dryer, in addition to considering the quality of the dryer and other factors of the dryer itself, it is also necessary to comprehensively compare the manufacturers of the Rotary Dryer equipment. Because Dryer manufacturers will produce a lot of dryer equipment, including slime dryer, chicken manure dryer, rotary drum dryer, grain dryer, etc.
• Compare prices for Rotary Dryer as well. Purchase dryer equipment with comprehensive performance ratio. Investigate the manufacturer of the dryer: First, the manufacturer of the drying equipment should be inspected to find out whether the factory has experimental equipment, whether there is experimental data for this material, and what the experimental results are. You should listen carefully to the factory's report on the experimental phenomenon, to know whether there is the manufacturing capacity of the mentioned model, whether the processing method of the drying equipment factory can meet the requirements, and listen to the statement of the processing method of the drying equipment manufacturer for the model.
• Rotary Dryer manufacturer's work performance: The level of drying equipment manufacturers depends to a certain extent on its work performance. In general, the more work performance, the stronger the equipment manufacturing capacity. Because the technology will continue to be exhausted by manufacturing equipment. If it is the first to manufacture this model, the user must be cautious, and the maturity of the technology should be carefully demonstrated.
• Rotary Dryer Manufacturer's Reputation: Drying equipment requires frequent maintenance, and sometimes there are problems that are difficult for users to solve during use. Some wearing parts have no generality. Whether the factory can permanently provide users with technical advice and spare parts supply is a problem that users must consider when choosing a drying equipment manufacturer.
• Other users of the drying equipment manufacturer should be asked to understand the manufacturer's reputation. Look at the same models from different dryer manufacturers: As mentioned earlier, drying equipment can also have problems of one kind or another when scaling up.
• It is necessary to check whether the factory has experience in manufacturing models of the same specification required by users. If the experience in this area is accumulated, the equipment success rate is relatively high. Investigate the drying effect of the same or similar materials: If further investigation, the Rotary Dryer equipment manufacturer can provide the drying experience of the same material, which will increase the credibility of the project.

Nonetheless, drying is a highly specialized subject that is difficult for non-professionals to master in a short period of time. If possible, hiring Rotary Dryer experts to check it during the inspection of the project can improve the reliability of selecting equipment manufacturers.
