Introduction to horizontal dryer
The horizontal dryer is our flagship product of Hongtong Machinery in Gongyi City. After multiple structural modifications and performance improvements, the horizontal dryer produced by the factory has surprised customers in terms of drying effect.
The horizontal dryer is named after the horizontal placement of the drying cylinder, and its structure is more suitable for use as a large dryer compared to a vertical dryer, with a variety of models. It mainly consists of a head frame, a tail frame, a middle frame, a traction chain, a flipper, a guide rail, an automatic tensioning device, an automatic heating equipment, and other parts. The entire drying process requires the coordination of multiple equipment, such as cyclone separators, dust collectors, induced draft fans, hot air stoves, etc.

Horizontal dryer is suitable for materials
The horizontal dryer is suitable for drying materials such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate, slag, clay, limestone, phosphogypsum, steel mill slag, power plant coal slurry, and sewage treatment plant sludge.

Structure composition of horizontal dryer
What are the components of a horizontal dryer and what is the function of each component? Understanding the structural composition and the functions of each component of a horizontal dryer is of great help for troubleshooting, maintenance, and upkeep in the daily production of horizontal dryers.
The main components of a horizontal dryer include a heating device, a feeding device, a supporting wheel device, a drying cylinder, a transmission device, a blocking supporting wheel device, a discharge device, a cyclone separator, and an induced draft fan. Our technicians from Hongtong Machinery Factory will now provide you with a detailed introduction to the functions of each component of the horizontal dryer.
1. Heating device: It can generally be divided into co current and counter current drying. Downstream drying is due to the wet material entering the horizontal dryer equipment and coming into contact with a higher temperature drying medium. In the initial stage, the drying force is greater, and later, as the material temperature increases, the temperature of the drying medium decreases. Therefore, it is suitable for materials that do not require high final moisture content (i.e. drying degree). The discharged dry material has a lower temperature, making it easier to transport. However, in terms of dust generation, fine materials are easily carried away by airflow, resulting in a large amount of dust. Counter current drying has a relatively uniform drying force during the drying process, making it suitable for drying materials with strict requirements. The dust carried by the dry medium is filtered through the wet material area, and the dust content in the airflow is relatively low.
2. Feeding device: It can be divided into single screw feeding and double screw feeding. The single screw feeding is suitable for materials with low viscosity, low moisture content, and easy drying. The double screw feeder is suitable for materials with high moisture content and high viscosity.
3. Wheel support device: made of cast steel, with two identical gears at the front and rear, each consisting of 2 wheels, 4 bearings, and 1 large base. Function: To support the tire belt, rotate the cylinder, and provide radial positioning.
4. Drying cylinder: The cylinder part includes the cylinder and internal devices. The cylinder is a horizontal rotating cylinder made of boiler steel plate rolled and welded. At the feeding end of the cylinder, a blocking ring and a guide plate are installed to prevent material backflow. At the hot end of the cylinder, a heat-resistant protective plate can be installed to protect the cylinder. At the feeding end of the cylinder, a blocking ring and a guide plate are installed to prevent material backflow. At the hot end of the cylinder, a heat-resistant protective plate is installed to protect the cylinder.
5. Transmission device: composed of electric motor, reducer, gear and other parts. The transmission device is a key part of the rotary dryer, used to drive the operation of the rotary dryer. The designed rotary dryer transmission device must select appropriate motors, transmission methods, installation positions of gears on the cylinder body, types of reducers and couplings according to requirements, so that the transmission device can achieve optimization, reduce energy consumption, save resources, and lower production costs.
6. Supporting wheel device: Install one on each side of the discharge end wheel belt, with the axis perpendicular to the cylinder. Function: To prevent the cylinder from moving up or down.
7. Discharge device: The discharge method can be divided into three types: axial discharge, radial discharge, and central discharge. ① Axial unloading: The simplest method is to have the material automatically flow out at the lower end of the drum. If you want to maintain a certain thickness of the material inside the cylinder, you can install an annular material blocking ring at the end of the rotary drum. Also make the cylinder end conical. ② Radial discharge: Multiple holes are opened on the cylinder at the discharge end, and the material is discharged from these holes. This valve is used for unloading materials such as cylindrical screens and heat exchange cooling cylinders for cement clinker. ③ Central unloading: At this time, the rotary drum is equipped with 3-4 scoops at the unloading end. After picking up the material, it is poured into the unloading tube located at the center of the drum and discharged.
8. Cyclone separator: A cyclone separator, also known as a centrifugal separator, uses the centrifugal force generated by the rotational motion of a gas flow containing fine powder to separate the fine powder from the gas.
9. Induced draft fan: The induced draft fan is generally arranged at the rear of the drying equipment, and its function is to discharge the exhaust gas from the drying operation The fan is mainly composed of fan blades, louvers, window opening mechanism, motor, pulley, air inlet cover, inner frame, casing, safety net and other components.

Working principle of horizontal dryer

The structure and working principle of a horizontal dryer are relatively simple, but many customers are unaware of them. Understanding the working principle of a horizontal dryer is of great help for its daily operation, maintenance, and upkeep in production. Now, our Hongtong technicians will explain the working principle of the horizontal dryer to you.
Wet materials are transported by belt conveyors or bucket elevators to the hopper and added through the feed inlet. The main body of the rotary dryer is a slightly inclined and rotatable cylindrical body When the material enters the interior of the cylinder, it is dried by coming into contact with the hot air passing through the cylinder in a downstream or upstream direction, or by effectively contacting the heating wall. After drying, the product is discharged from the lower part of the other end During the drying process, the material is slowly rotated by the cylinder and moves from the higher end to the lower end under the action of gravity. There is a forward copying plate installed on the inner wall of the cylinder, which continuously picks up and sprinkles the material, greatly enhancing the thermal contact surface of the material, improving the drying rate, and promoting the material to move forward. After drying the material with heat carriers (hot air, flue gas), the dust in its narrow strip is collected by a cyclone dust collector and then discharged.

1. The horizontal dryer is equipped with an automatic tensioning device, which ensures smooth operation and easy flipping of the chain plate, thereby solving problems such as chain dropping, jamming, and deviation.
2. The screen plate of the horizontal dryer is made of heat-resistant steel punched into a mesh shape, which has high strength, is not easily deformed, and has good breathability.
3. The chain plate of the horizontal dryer is driven by a speed regulating motor, which can adjust the operating speed and control the drying time as needed
4. Digital display of temperature in each section of the kiln body, making it easy to grasp and control the temperature inside the kiln.
5. There are maintenance channels on both sides of the flipping machine inside the kiln for easy maintenance of the equipment.
6. The hot blast stove only uses chain furnace automatic heating equipment for heating, with automatic coal feeding and slag removal, high thermal efficiency, wide adaptability to coal types, clean and environmentally friendly, and time-saving.
7. The horizontal dryer is equipped with a fire prevention device, with three thermocouples installed at the kiln head, kiln middle, and kiln tail. The flue inlet is equipped with a smoke gate. In case of mechanical failure, the gate is immediately lowered to isolate the heat source and prevent fire.
8. The horizontal dryer adopts negative pressure induced draft, which reduces dust and evenly distributes hot air. There is a settling tank at the air inlet and the bottom of the chimney, and the dust emission meets the standard. The flipping plate is equipped with a spiral automatic ash removal device at both ends, which is simple and convenient. Positive pressure air blowing generates large amounts of dust, causes severe pollution on the production site, and the air ducts are prone to clogging.
9. Design the ball to enter and exit from the low-temperature zone at the tail of the machine, with the coal balls gradually heated from the low-temperature zone and the high-temperature zone to avoid cracking and bursting of coal balls containing 8-10% moisture due to rapid heating after forming, resulting in a low damage rate.
10. Negative pressure induced draft kiln tail air temperature ≤ 100 ℃, low dust content, long service life of induced draft fan, and low operating cost. Positive pressure blower fans can experience imbalance, vibration, and abrasion due to long-term exposure to high temperatures and dust, resulting in a short lifespan and high operating costs.
