Lining of drive drums of belt conveyors. Lining of drive drums. Lining plate kv

Lining with replaceable elasto-metallic (EM) plates “MARAFON EK”» used to protect conveyor drums when operating them in the coal and mining industries, as well as when operating drums in aggressive environments, at temperatures environment from -45 to +180°C and air humidity no more than 98%.

MARAFON EK ® friction linings are a unique and proven method for increasing conveyor and elevator productivity. Specifically designed for direct installation on the drive drum, these products can transform any conveyor system into high-performance equipment without requiring much Maintenance. Along with a striking increase in the coefficient of friction (adhesion) between the belt and the drum, the drum surface is protected from damage, as well as self-cleaning, in which material does not accumulate on the drum.

The combinations of elastomers and design features the products provide significant advantages over traditional vulcanized drum liners, cold welding or attached to bolted connections. The unique factory fastening system eliminates the separation of the pads, making the MARAFON EK ® ideal option for severe operating conditions on high power drives or when using rubber rope conveyor belts.

Elastomers used in potentially hazardous mining processes, as well as during the transportation of grain and fertilizers, are approved federal service on environmental, technological and nuclear supervision and a certificate of conformity issued by VOSTNII.

Production of overlays

provides the possibility of producing elastomers of special composition for further vulcanization under high pressure on special steel plates that can be installed on any drums. The linings move in special holders welded or bolted to the surface of the drum.

    Friction linings are made using modern elastomers, providing excellent adhesion to the drive drum, elastic movement and long service life. The elastomer maintains its integrity under the most severe operating conditions.

    Hot vulcanization, performed in the factory under pressure, ensures excellent bonding of the rubber to the steel lining. There is virtually no overlay failure due to loss of adhesion and separation - the most common problems encountered with traditional overlays.

    Steel linings are manufactured with high precision, which ensures the possibility of installation on drums of any diameter. The necessary stability of the linings and a long service life are guaranteed.

    Stainless steel holders are welded or bolted to the surface of the drum for reliable fixation of the friction linings. When installed correctly, the pads do not move or come off under the influence of the transported material or belt movement.

These four features make MARAFON EK ® products a unique and reliable choice for installation on all conveyor and elevator drums. MARAFON EK ® pads can subsequently be replaced on site, usually without dismantling the belt or drum. Possible replacement Removing worn or damaged pads is even faster and easier since the holders are already installed.

Lining services from the Flisbant company

Qualified specialists companies carry out fast and high-quality lining of conveyor drums not only on their own premises, but also on the customer’s premises.

The fact that we have a large stock range of high-quality lining materials, including German primers and special ones, is in favor of contacting Fliesbant. adhesive compositions, which allows minimizing downtime of conveyor equipment.

Lining is a method of treating a surface to make it resistant to mechanical damage or to influence chemical substances And physical phenomena(temperature).

Essentially, this is a way to strengthen the surface. Most often, parts of heavy industry mechanisms (mining, metallurgy, heavy engineering and the like) that are susceptible to constant friction succumb to it. This treatment enhances their wear resistance to mechanical abrasion, thereby extending the service life of the mechanisms.

Lining belt conveyors and their drive drums is rubberized. That is, on work surface special plates (linings) made of rubber or rubberized with ceramic inserts are applied.

They not only increase service life conveyor drum, but also improve its movement, adhesion to running surfaces and prevent the belt itself from coming off the conveyor.

Drum lining methods and steps

Lining belt drums carried out by three main methods: hot or cold vulcanization, and mechanically. Depending on the method of their application, manufacturers produce different models.

Application process lining plates occurs in several stages. First, the surface is sanded or blasted, this is done to give it roughness. Then a layer of primer is applied, and after that a layer of glue, which will hold the pad itself. Thanks to all these procedures, the pad is securely attached to the drum.

Polymer coatings for lining

The Russian company TD Plastics Group is engaged in the design and production of various coatings, including linings for most belt sliding mechanisms. Produced polymer coatings- these are fundamentally new materials that replaced their predecessors - metal protective coatings.

They do not require such careful maintenance, but they last much longer. The product catalog from TD Plastics Group contains a wide range of materials for many areas of production: woodworking, mining and oil production, electrical installations, instrument making, water treatment, and the military-industrial complex.

In addition to finished products, it is possible to manufacture them according to special drawings with preliminary development by the company’s specialists.

The process of lining the main drive drum of a belt conveyor is usually carried out by the equipment manufacturer independently, using special technology cold vulcanization by means of which, smooth surface The drum is covered with especially durable or “lining” rubber, which may contain ceramic inclusions. On this moment, this method is the most optimal. The lining of the drums of belt conveyors effectively prevents possible slippage of the drive drum that occurs when the proper level of load on the conveyor belt is exceeded.

In some types of conveyor devices, drive drums are installed, the surface of which remains completely smooth after lining; in some, there are patterns on the lined coating, which, by the way, are a kind of business card manufacturer. However, such a pattern is not intended to perform an aesthetic function at all, but a completely utilitarian one; it allows the drive drum to self-clean, which ultimately provides its surface with better adhesion to the conveyor belt. By the way, ceramic inclusions, in turn, increase the wear resistance of the rubber coating of the drive drum, that is, the lining itself.

How to line the drive drums of belt conveyors

So, lining is the application of a protective layer to the surface of the drums driving the conveyor belt. Rubber is mainly used for lining; however, at the request of the customer, the manufacturer of the conveyor belt can apply any protective material that meets the requirements of the specific production and operation of the conveyor. As options for replacing rubber, silicone, acrylic, polyurethane, and so on can be used, and the protective layer in such cases is simply glued to the surface of the drive drum.

Advantages of lining:

  • Self-cleaning of drive drums of belt conveyors;
  • Improving traction and eliminating slippage;
  • Elimination of accumulation of moisture and dirt;
  • Stable belt tension and set speed;
  • Increasing the service life of the drive drum, conveyor belt and all equipment in general;
  • Reliable protection metal drum from rust;
  • Protection of the drum and belt from mechanical influences.

Belt conveyor drum lining technology

It should be noted that a grooved lining, that is, having either a pattern or ceramic inserts, provides more high level adhesion of the surface of the drive drum and the conveyor belt, as well as best indicator traction factor, which eliminates excessive tension of the conveyor belt, thereby extending its service life.

The lining process does not take much time from the manufacturer; the application of any material as a protective layer on the surface of the drive drum occurs quickly and efficiently. During the operation of a drum with lining, you can save time on repairs and extend the service life of the entire conveyor belt device.
