Organo-Ceramic Brake Linings for Heavy-Duty Industrial Brake & Clutch Applications

STOP THE TEAR – MINIMIZE THE WEAR with MICKE 190-30 CC high friction, extremely wear resistant, and mechanically ultra strong ceramized organic woven brake linings, which provide extreme wear resistance + ultra mechanical strength with increased dynamic and static friction coefficients thanks to MICKE’s own specially-developed, special inorganic ceramizing process.

CUSTOMER
Our final customer, Société Nationale Industrielle et Minière (SNIM), is a 75% state owned company which employs 5000 permanent workers and operates the largest open pit iron ore mines in Northern Africa – Guelb el Rhein, Kedia d’Idjill, and M’Haoudat – near the city of Zouerate in the province of Tiris in Mauretania. After drilling and blasting, the iron ore  is loaded onto heavy-duty 200-ton Le Tourneau mine trucks by huge 26 m³ shovel volume P&H drag lines. The trucks haul the ore to crushing terminals, from which the ore is transported to the nearby concentration and enrichment plants via belt conveyor systems. The concentrated ore finally leaves by train, and is shipped over 700 km to the ore port terminals at Nouadhibou on the Atlantic coast. In 2010, SNIM produced approximately 12 million tons of hematite and magnetite iron ore, and still owns mining reserves for approximately 100 years of exploitation. SNIM is regarded the 7th biggest supplier of iron ore on the international market and had 1.1 billion USD of turnover in 2010.

ceramised organic woven brake linings

OBJECTIVE
1. Material alternatives to preexisting organic, homogeneously mixed and hot pressed US made brake linings used on the 2250 mm diameter steel band brakes of the clutch and brake winches in the customer’s shovel draglines.

2. Achievement of continuous, highest possible static and dynamic friction
coefficients µ >= 0.5.

3. Increase of mechanical stability of the bolted brake and clutch linings by at least 50% of existing values.

4. Considerable increase of lining lifetime by a factor of two.

5. Considerable reduction of mechanical wear of brake drums by at least a factor of two.

6) Considerable reduction of specific pressure per mm² brake lining surface down
to 75% of existing values.

7) Considerable reduction of repair & maintenance cost on dragline winches.
