How to use a sand three tube dryer correctly?

Sand triple drum dryer is a common industrial equipment used for dehydrating and drying materials with high humidity. Before using a sand three tube dryer, it is necessary to first understand its working principle and correct operating methods to ensure the normal operation and safe use of the machine.

The working principle of the sand three tube dryer is to use the heat generated by combustion to evaporate the moisture in the material through the contact between hot air and wet material. Due to its structure being divided into three cylinders, continuous feeding, feeding, and discharging processes can be carried out simultaneously. The following will introduce the correct method of using a sand three cylinder dryer from the aspects of preparation work, operation steps, maintenance, etc.

1、 Preparation work

Confirm the power supply of the sand three drum dryer and inspect and maintain the equipment. Ensure stable power supply and no faults in equipment circuits to avoid affecting normal operation.

Check if all components of the sand three tube dryer are intact, such as the motor, reversing valve, temperature controller, etc. If any damage or malfunction is found, it needs to be repaired or replaced in a timely manner to ensure the normal operation of the equipment.

Check the fuel supply and combustion system to ensure sufficient fuel supply and normal operation of the combustion system.

2、 Operation steps

Feed the wet material to be processed into the feed inlet of the sand triple drum dryer. When loading materials, it is necessary to ensure that the loading is uniform and not stacked too high, so as not to affect the normal operation of the equipment.

Turn on the hot air stove or heater and ignite the combustion furnace. The fuel can be coal, fuel oil, natural gas, etc. Choose the appropriate fuel according to the specific situation, and adjust the supply of fuel according to equipment specifications and production requirements.

Turn on the motor to start the cylinder rotating. Hot air gradually evaporates the moisture in the material by coming into contact with it inside the cylinder. At the same time, there are specialized discharge ports and collection systems along the direction of the cylinder for collecting processed materials.

Adjust the temperature and speed of the sand triple drum dryer according to the properties and requirements of the material. Generally speaking, the dehydration and drying speed of materials are related to temperature and speed, and need to be adjusted according to specific circumstances.

During operation, it is necessary to observe the working status of the dryer in a timely manner to ensure that the equipment is working properly. Especially, close attention should be paid to temperature control devices to prevent temperatures from being too high or too low, which may affect dehydration efficiency or even cause safety hazards.

In short, the correct use of a sand three tube dryer requires comprehensive consideration from the aspects of preparation work, operation steps, and maintenance. Only by operating and maintaining the equipment correctly can the normal operation of the dryer be ensured and its service life be extended. During use, it is necessary to strictly follow the instructions and safety operating procedures, and conduct regular inspections and maintenance to ensure work safety and the normal operation of the equipment.
