Rockwool single-drum dryer

Structural composition:

• Drum body:

It is the core component of the dryer, usually made of metal material, with good sealing and heat resistance, and can withstand the high temperature and weight of the material during the drying process.

• Wheel device:

Located at both ends of the cylinder, it is used to support the cylinder and enable it to rotate stably in the horizontal direction. There are generally four rollers, evenly distributed on both sides of the cylinder to ensure the smooth rotation of the cylinder.

• Transmission device:

It includes components such as motor, reducer, coupling, etc., which provide power for the rotation of the cylinder. The motor transmits power to the coupling through the reducer, and the coupling is connected to the wheel belt of the cylinder to drive the cylinder to rotate.

• Feeding device:

It is responsible for conveying the rock wool material to be dried into the cylinder. The feeding device needs to ensure that the material can enter the dryer evenly and stably to ensure the consistency of the drying effect.

• Discharging device:

After the drying is completed, the dried rock wool material is discharged from the dryer. The discharging device usually has a certain degree of sealing to prevent hot air leakage and dust overflow.

• Heat source device:

provides heat for the drying process. Common heat sources include coal, natural gas, fuel oil, biomass particles, etc. The heat source device is connected to the inside of the cylinder through a pipeline, and the hot air flow is transported to the dryer for heat exchange with the rock wool material.

• Dust removal device:

Since rock wool will generate a certain amount of dust during the drying process, the dust removal device is used to collect and treat the dust to reduce environmental pollution. The dust removal device is usually connected to the discharge end of the dryer through a pipeline, and the dust-containing gas is sucked into the dust removal equipment for purification.

• Working principle:

The rock wool single-drum dryer is a rotary dryer. After the wet rock wool material enters the cylinder from the feeding device, the material is constantly turned and lifted as the cylinder rotates. At the same time, the hot air flow generated by the heat source device enters the cylinder and fully contacts the rock wool material, causing the moisture in the material to gradually evaporate. The evaporated water vapor is discharged from the discharge end along with the hot air flow, and the dried rock wool material is discharged from the discharge device, completing the entire drying process.

Advantages and characteristics of rock wool single-drum dryer:

High drying efficiency:

• Large-capacity processing:

The single-drum structure has a large internal space and can process a large amount of rock wool materials at one time, which improves production efficiency. For example, for large rock wool production enterprises, single-drum dryers can meet their large-scale production needs.

• Good heat exchange:

Through reasonable design, such as optimized lifting plate structure and drum speed, the rock wool material can be fully in contact with the hot air flow in the drum, which improves the heat exchange efficiency and speeds up the drying of the material.

Good drying quality:

• Uniform drying:

During the drying process, the rock wool material is constantly turned and moved in the drum, so that the material can be heated evenly, avoiding local overheating or uneven drying, and ensuring the quality stability of the rock wool after drying.

• Little damage to the material:

Compared with some other drying methods, the single-drum dryer has less mechanical damage to the rock wool material, can maintain the fiber structure and physical properties of the rock wool, and does not affect its subsequent use and processing.

Low energy consumption:

• Efficient heat source utilization:

It can select appropriate combustion equipment and heat exchange methods according to different heat sources to improve the utilization efficiency of the heat source and reduce energy consumption. For example, the use of advanced combustion technology can make coal and other fuels fully burn and release more heat.

• Good thermal insulation performance:

The cylinder and pipes of the dryer are made of high-quality thermal insulation materials, which reduces heat loss and further reduces energy consumption.

Strong equipment reliability:

• Solid structural design:

The main body of the cylinder and the supporting wheel and other key components are made of high-strength materials, and after strict processing and assembly processes, the structural strength and stability of the equipment are ensured, and it can maintain a good working condition during long-term operation.

• Low maintenance cost:

The equipment has high operating reliability and low failure rate, which reduces the maintenance and repair workload of the equipment and reduces maintenance costs. At the same time, the replacement of some wearing parts is also relatively convenient, which shortens the downtime of the equipment.

Easy operation:

• Automatic control:

Equipped with advanced automatic control system, it can monitor and control the temperature, speed, feed amount and other parameters in the drying process in real time. The operator only needs to set the relevant parameters, and the equipment can run automatically, which greatly reduces the labor intensity.

• Easy to operate and maintain:

The operation interface of the equipment is simple and clear, and it is easy for the operator to master. At the same time, the daily maintenance of the equipment is also relatively simple. You only need to regularly check, clean and lubricate the equipment to ensure the normal operation of the equipment.

Strong adaptability:

• Applicable to a variety of materials:

Not only suitable for drying rock wool, but also for drying other similar materials, such as slag, sand, clay, etc., with strong versatility.

• Low requirements for material humidity:

It has a good drying effect for rock wool materials with different humidity and can adapt to the requirements of different production processes. Even rock wool materials with high humidity can achieve ideal drying effects in a shorter time.
