Products for the
Mining Industry
In mining – both underground and in open-cast operations – equipment is exposed to extreme conditions: highly abrasive dust, constant moisture, mechanical impact and high-frequency vibration, extreme pressures and severe temperature fluctuations. WEICON products are specifically developed to withstand these harsh conditions. They perform reliably where abrasive materials, temperature fluctuations and mechanical impact place heavy demands on materials and connections. In maintenance and new installations involving heavy-duty machinery, they help ensure reliable operation: stabilising joints, protecting sealing points against pressure, chemicals and micro-movements and extending the service life of components even under the most demanding continuous loads.
WEICON products are designed to perform reliably under the toughest mining conditions – whether in heavily loaded conveying systems, crushing and screening plants operating in dusty environments, highly stressed conveyor belts, pumps and valves exposed to pressure and cavitation or exposed peripheral equipment.
Our high-performance epoxy compounds from the Epoxy Solutions range, adhesives, technical sprays and sealing and assembly pastes provide reliable performance and high process reliability.
They also help ensure efficient, predictable maintenance intervals, even in the most demanding mining environments.

Wear protection in conveying and material handling areas
with WEICON HP (primer), WEICON WPN, WEICON WPG-19, WEICON Ceramic BL and WEICON Ceramic HC 220
Heavy abrasion caused by fine dust and granular bulk material leads to rapid wear and unplanned downtime in chutes, hoppers and transfer channels. With a cold-applied wear protection system, repairs in the mining industry can be carried out quickly and without dismantling the equipment. After coarse sandblasting, Bristle Blaster treatment or grinding, the surface is properly prepared for coating application. On difficult substrates and in areas subject to vibration, WEICON HP is used as a primer. WEICON WPN is then applied at a thickness of 3–5 mm, while WEICON WPG-19 is used for layer thicknesses of 20 mm and above. On low-friction substrates, an additional layer of WEICON Ceramic BL or WEICON Ceramic HC 220 improves the sliding properties. Subsequent thorough compression ensures the material achieves its full performance. The coating reliably protects against abrasion and impact, extends service life and reduces downtime costs. The repair is simple, quick and can be refurbished whenever wear occurs. This makes it ideal for bulk material handling, processing and raw material extraction in open-cast and underground mining operations.

Impeller repair in a cement factory
with WEICON Cleaner Spray S, WEICON HP, WEICON WPN and WEICON Ceramic HC 220
In cement plants, abrasive raw materials cause significant material loss on impellers. Without effective wear protection, efficiency decreases and maintenance becomes difficult to plan. To carry out the repair, the blades are mechanically cleaned and roughened, then degreased with WEICON Cleaner Spray S. This is followed by wet-on-wet coating: WEICON HP serves as the bonding primer, WEICON WPN fills the worn areas and WEICON Ceramic HC 220 provides the finishing layer for a precise fit (observe the overcoating interval). Finally, the impeller is balanced to ensure reliable operation. The smooth ceramic coating reduces friction, increases conveying capacity and extends service life – an efficient maintenance solution for the cement industry and mining.

Filling the gap on a rotor shaft in a gravel washing plant
with WEICON WR
In gravel plants, play and vibrations in rotor shafts lead to premature wear, loss of performance and unplanned stoppages. To increase stability, in our application example, the 4 mm gap between the inner and outer shafts is filled with WEICON WR, ensuring that no air bubbles are trapped. Threaded holes are prepared at one-metre intervals and connected with hoses and valves. The highly filled epoxy resin system WEICON WR is injected from the bottom up until material emerges from the uppermost hole. In this way, the gap is completely filled and air inclusions are avoided. After 24 hours at room temperature, the gap fill has cured and the gravel plant is ready for operation again. The measure increases shaft rigidity, reduces vibrations and extends service life without the costly replacement of the assembly. The application can be carried out in-house and is ideal for plant engineering in the mining industry.
Maintenance work on the outlet base plate of a hopper
with WEICON Cleaner S, WEICON Surface Cleaner and WEICON WP
Abrasive bulk material places particular strain on the outlet zones of hoppers in mining operations. High flow and impact speeds occur in these areas, shortening maintenance intervals and increasing downtime. To provide long-lasting protection for these critical areas, the base plate is first sandblasted and all dust is thoroughly removed. The surface is then prepared with WEICON Cleaner S or WEICON Surface Cleaner. Next, WEICON WP is applied as a wear protection layer. The layer is compacted and smoothed with PE film to create a homogeneous, dense surface. The coating protects the base material and typically extends the maintenance interval from around three to at least six months. It also reduces downtime costs. Once the protective layer has been worn away, the plate can be quickly recoated – an economical maintenance solution for hoppers, chutes and linings in mining.

Repair of damage to a bucket elevator conveyor belt
with WEICON Cleaner Spray S, WEICON 1K Primer G and WEICON Urethane 85
In conveyor systems in the cement industry, abrasive fine particles and material impact cause localised damage to the rubber belt. If left untreated, this can compromise the embedded tension cords and shorten the service life of the belt. To stabilise the damaged area quickly and reliably, coarse rubber residues are removed. The surface is then roughened with abrasive cloth and cleaned with WEICON Cleaner Spray S. Next, WEICON 1K Primer G is applied to ensure reliable adhesion. WEICON Urethane 85 is then applied and smoothed evenly. The elastic repair protects the cords against corrosion, extends the service life of the belt and reduces downtime costs – an economical repair without dismantling or vulcanisation.

Coating of the cell wheel of a rotary valve in a cement plant
with WEICON Anti-Stick
Fine mineral bulk materials tend to adhere to surfaces in cement plants. Material builds up on the cell wheel of the rotary valve, causing uneven material flow and reducing conveying capacity. To reduce material build-up and extend service life, the stainless steel components (approx. 3.5 m²) are first blast-cleaned, then warmed with a hot-air blower and finally coated with WEICON Anti-Stick in a two-coat system. The non-stick surface reduces friction, prevents material build-up and stabilises throughput. The Anti-Stick system protects the base material, extends service life and ensures efficient, trouble-free operation of the rotary valve.
