Brake Lining Compounds Kneader

Perfect homogeneity ensures consistent friction coefficients, heat resistance, noise reduction, and wear properties. The kneader’s intense shear forces prevent agglomeration and maintain batch-to-batch consistency, which is essential for safety, performance, and durability of the finished friction products.

The machine is offered in Stainless Steel 316, Stainless Steel 304, and Mild Steel. Stainless-steel versions can be finished to matt or mirror polish as required. Mild-steel units receive one coat of red oxide primer followed by two coats of epoxy paint.

Models range from ASM-50 (approx. 50 L working / 80 L gross capacity) to ASM-3000 (approx. 3000 L working / 3800 L gross capacity). Motor power is available in both general and heavy-duty ratings, with voltage adjustable to suit local power requirements.

Discharge options include manual (hand-wheel operated) or automatic hydraulic operation. The heavy-duty tilting design allows 75°–140° hydraulic tilting for complete and rapid discharge without leftovers. Screw systems or automatic valve discharge can also be added.

Yes. A jacket for heating or cooling (water or thermal oil) is available, complete with mineral-wool insulation. Rotor cored cooling further maintains compound temperature within ±2–3 °C, preventing premature curing of phenolic resins during intensive kneading.

It uses high-shear sigma/Z-blade or intermeshing rotors engineered for abrasive and fibrous compounds. Rotors, mixing chamber, and side plates are made of hardened alloy steel with hard chrome plating or tungsten carbide coating for superior wear resistance and extended service life. Dust-stop sealing technology prevents powder leakage.

The kneader can be equipped with PLC + HMI automation featuring recipe management, real-time torque and temperature monitoring, and batch traceability. Safety features include emergency stop, rotor reverse, anti-overload protection, a pressure lid system (hydraulic or pneumatic), and full compliance with CE/ATEX standards.

Optional features include a liquid spray system, vacuum system, blades cooling arrangement, screw system, and automatic valve discharge system. These enhance process flexibility for complex friction material formulations.

In the tangential design, Z-shaped blades rotate toward each other at different speeds (typically a 3:2 ratio), creating intense shearing and kneading ideal for high-viscosity compounds. The overlapping design rotates blades at the same speed for faster material interchange and lower shear, suitable for lighter-viscosity mixes. Both designs help achieve thorough dispersion of fibers, resins, and fillers.
