Which way is better for coal mine drum lagging ?

On the coal mine, it feels like all the heavy machines there, and it is better to use the popular plug-in plate lagging for the drum lagging piece. Hehe, I don't know much about this, I heard from my father, he is a mechanic in my small coal mine. Hope it helps.

Commonly used is cold adhesive. Ceramic, plug-in plate lagging Among them, most of them are plug-in type.

In order to ensure the safety of on-site transportation and improve the life of the conveying system, the drum lagging material with fireproof and flame retardant performance is mostly required.

The fireproof materials usually used in the underground drum lagging in coal mines include drum lagging fireproof and flame retardant glue and drum lagging fireproof and flame retardant rubber board, which work together to maximize the bonding performance and fire retardant performance after lagging to the maximum.

Fireproof and flame retardant glue.

At present, the number of high-temperature resistant glues is also increasing, but the fireproof and flame-retardant glues are relatively few. At present, the commonly used cold vulcanized drum adhesive glue SK313 is one of the few fireproof and flame retardant adhesives.

This glue is imported from Germany, and the curing speed is more than doubled when used with the curing agent, which can greatly improve the efficiency of the drum lagging process. After curing, the bonding strength can reach 10,000cps, and it has both fireproof and flame retardant properties, especially suitable for underground use in coal mines.

Fireproof and flame retardant rubber sheet.

The fireproof and flame retardant rubber board is also a kind of rubber board that is relatively hot at present, which can consciously isolate the flame and self-extinguish when leaving the fire, effectively improving the safety factor of the on-site transportation system.

Among them, the most frequently used is the new RIT diamond-shaped wear-resistant and flame-retardant rubber plate, which is engraved with a diamond-shaped pattern, which can greatly improve the friction coefficient between the roller and the conveyor belt, and increase the anti-slip and wear-resistant performance. Moreover, the rubber plate can form a vulcanization reaction with the cold vulcanized glue, and the adhesion force can be increased to more than 3 times that of the ordinary rubber plate, which can effectively ensure the bonding continuity after starting.

The material of the rubber is an important factor to ensure whether the drum is wear-resistant, the performance parameters of the rubber affect the quality of the rubber, so it is necessary to choose the rubber varieties that meet the industrial and mining conditions, the main rubber covering in the market is divided into imported rubber and domestic rubber, the general industrial and mining conditions are mostly domestic rubber, and for the harsh industrial and mining conditions, most of the high wear-resistant rubber plates imported from abroad are selected.

The selected manufacturer must have a good on-site analysis and construction ability, according to the actual situation to choose different thickness, hardness and wear resistance of the rubber plate, no practical choice often causes the lag to wear too quickly.

The function of the pulley lagging of the belt conveyor in the underground coal mine is to protect the outer rubber of the belt drive drum in the second horizontal transportation lane from being damaged, so that the belt can operate normally without slipping.

Belt conveyor is the abbreviation of belt conveyor, there are fixed and mobile, simple structure, high efficiency. Continuous conveying machinery with flexible conveyor belt as material bearing and traction components. An unended conveyor belt surrounds the drive pulley and the reversing pulley.

The upper and lower branches between the two rollers are each supported by a number of idlers. The material is placed on the upper branch, and the friction between the drive pulley and the belt is used to pull the conveyor belt and the material to run. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions, and can also be used for assembly lines for certain process operations.

The structure is simple, the work is stable and reliable, the adaptability to materials is strong, the conveying capacity is large, the power consumption is small, and the application is wide.

The main purpose of pulley lagging is to prevent the belt from slipping. Zhengzhou DPT - conveyor belt care expert, specializing in providing conveyor belt repair, conveyor belt hot gluing, and roller on-site cold lagging operations.

The main thing is to increase the friction between the belt and the roller.

You can be considered to have asked about this, because my previous company was to make pulley lagging to protect the belt from debris damage during transmission, and then to increase friction to the conveyor belt and standardize the direction of the conveyor belt, I hope it can help you.

1. When the metal surface of the drum is polished, it should be polished clean.

2. Choose the right materials: such as adhesives, cleaning agents, metal treatment agents, rubber sheets and other materials, it is best to choose the same series of products.

3. Sealing treatment: treatment of butt seam or lap joint.

4. Pay attention to construction details: dust, temperature, humidity, etc.

Whether you choose ordinary materials or choose imported RAMIMTECH lagging series materials, you must be careful and careful during construction.

1. Adhesive.

Drum cold lagging uses cold adhesive for on-site cold vulcanization of adhesives. It is mainly used for bonding wear-resistant rubber sheets.

2. Cleaning agent.

Cleaning agent, mainly used to clean the surface metal particles after grinding the metal surface of the drum.

3. Metal treatment agent.

Metal treatment agent: It is mainly used for the transition between the metal surface of the drum and the adhesive, which can increase the adhesion.

4. Rubber sheet.

The rubber board is generally divided into four forms: the plane of the back section, the herringbone, the diamond and the strip, but the rubber board is divided into two kinds of blue CN adhesive layer and no adhesive layer, the blue CN adhesive layer is the imported rubber plate, the bonding does not need to polish the adhesive surface, and the adhesive layer does not need to be polished, and the tungsten steel disc needs to be polished to increase the adhesion.

5. Sealing the rubber wheel.

The sealing glue is mainly used for the seam treatment of the drum rubber plate when it is docked. Prevents the seam from entering moisture or dust and affecting the bonding effect.
