Product description
The Ceramic Pulley Lagging Rubber Sheet is a highly effective, wear-resistant solution designed for
material conveying systems across multiple industries. It's
constructed from high-quality alumina ceramic (hardness exceeding
HRA85) and highly elastic rubber through a high-temperature
vulcanization process. The ceramic layer boasts over 10 times the
wear resistance of ordinary rubber, protecting it from erosion by
hard materials such as coal, ore, and cement. The rubber layer
absorbs impact, prevents ceramic shedding, and enhances friction
between the pulley and the conveyor belt to prevent slipping.
The product offers high and low temperature resistance from -40°C
to 120°C, as well as acid and alkali resistance. Customizable to
suit pulley size and operating conditions, it's suitable for both
new and refurbished pulleys. It significantly extends pulley life
by 3-5 times, while reducing energy consumption and maintenance
costs. It's widely used in conveyor pulleys across industries such
as coal, mineral processing, cement, steel, ports, thermal power,
and the chemical industry, providing reliable and stable wear
protection for customers worldwide.
Core Features: Wear-resistant, non-slip, and impact-resistant,
suitable for complex working conditions.
Highly Wear-Resistant Ceramic Layer: Utilizing high-quality alumina ceramic as the core wear-resistant
material, the ceramic boasts a hardness exceeding HRA85 and boasts
wear resistance over 10 times that of ordinary rubber. This layer
effectively withstands long-term erosion from hard materials such
as coal, ore, and cement, significantly extending the roller's
service life.
Highly Adhesive Composite Structure: Through a special process, the ceramic layer is tightly bonded to
a highly elastic rubber base. The rubber layer possesses excellent
elasticity and cushioning properties, absorbing material impact and
preventing ceramic dislodgement due to severe vibration. It also
enhances friction between the roller and the conveyor belt,
preventing slippage and ensuring stable operation of the conveyor
system.
Weather-Resistant and Corrosion-Resistant: The product's surface undergoes a special treatment for excellent
acid and alkali resistance, ensuring stable performance in humid
port environments, corrosive chemical environments, and
high-temperature thermal power plant environments, requiring no
frequent maintenance.

Production Process
Ceramic pulley lagging adheres to the following strict production
process to ensure product quality:
Raw Material Screening: High-purity alumina powder (≥92%) and high-quality natural rubber
are selected to ensure that the raw materials meet performance
standards.
Ceramic Sheet Forming and Sintering: The alumina powder is pressed and sintered at 1700°C to form a
high-hardness ceramic sheet.
Rubber Vulcanization: The rubber raw material is mixed with a vulcanizing agent and
vulcanized in a vulcanizer to form an elastic rubber base.
Composite Molding: Using a high-temperature vulcanization process,
the ceramic sheet and rubber base are laminated to form a
ceramic-rubber composite layer.
Pulley Fitting: The composite layer is cut and polished according to the
customer's pulley dimensions to ensure a precise fit.
Quality Inspection: Ceramic hardness, rubber elasticity, and composite layer adhesion
are tested. Only qualified products are packaged and shipped.

FAQ:
Q1: Does the ceramic sheet of the ceramic pulley lagging easily
fall off?
A: No. We use a high-temperature vulcanization process to tightly
bond the ceramic sheet to the rubber layer. The rubber layer is
then secured to the metal surface of the pulley with a specialized
adhesive. The adhesive is strong and has been tested to withstand a
peel force exceeding 150N. Under normal operating conditions, the
ceramic sheet will not fall off.
Q2: Can ceramic lagging be refurbished on old pulleys?
A: Yes. Simply derust and polish the old pulley surface, removing
the old, aged lagging. Then, ceramic lagging can be installed.
Refurbishment costs only one-third of replacing a new pulley,
significantly reducing costs.
Q3: Does the product have quality certification?
A: Yes. Our ceramic pulley lagging is ISO9001 certified.
Q4: What is the thickness of the ceramic lagging? How do I
determine the appropriate thickness?
A: Common thicknesses include 8mm, 12mm, 15mm, and 20mm. The
specific thickness should be selected based on the operating
conditions. For conveying hard materials such as ore and sand
(mines and ports), 15-20mm is recommended; for conveying
lightweight materials (food and textiles), 8-12mm is recommended.
For pulley diameters greater than 800mm or for high operating
speeds, 12-15mm is recommended. Customization recommendations can
be provided based on the customer's specific operating conditions.
Q5: What are the core advantages of ceramic pulley lagging compared
to traditional rubber lagging?
A: First, it extends service life by 3-5 times, reducing downtime
and maintenance costs. Second, the non-slip texture of the ceramic
surface reduces motor energy consumption and prevents localized
wear on the conveyor belt. Third, it is customizable and suitable
for both new and retrofitted pulleys, making installation simple
and non-disruptive.
Q6: Do you support custom sizes?
A: Yes, we can customize the drum diameter, width, and tile
arrangement.
Q7: Are anti-static or flame-retardant models available?
A: We offer special rubber materials such as anti-static and
flame-retardant to meet safety requirements in chemical and coal
mining applications.
