Brake Lining Compounds Mixer

The mixer is available in Stainless Steel 316, Stainless Steel 304, and Mild Steel. Stainless steel versions can be polished to matt or mirror finish as per customer requirements. Mild steel units receive one coat of red oxide primer followed by two coats of epoxy paint. PTFE shaft sealing is provided for compatibility needs.

Tangential action of mixing and kneading is obtained by ‘Z’ type (SIGMA) shaped blades that rotate accurately at different speeds toward each other (typically a 3:2 ratio), transferring product from one end to the other. The action combines bulk movement, stretching, folding, dividing, and recombining, with shearing and tearing against the blades and side walls for size reduction and uniform dispersion. An overlapping blade design is also available for certain viscosities.

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 (e.g., 5–7.5 HP for the smallest up to 100–120 HP for the largest), with voltage adjustable to the customer’s local power supply requirements.

Discharge can be performed via a hand-wheel-operated (manual) mechanism or a hydraulic-operated (automatic) system for tilting and complete emptying. Additional options include discharge through bottom valves or by means of an extrusion screw beside the container.

Yes. A jacket for heating or cooling applications can be fitted, complete with mineral wool insulation and cladding. This supports process temperature management important for resin curing agents and overall compound consistency.

Features include tangentially designed ‘Z’ blades for uniform mixing, a minimum gap between the trough inner shell and blades to prevent product sticking, robust construction for handling abrasive compounds under intense mechanical stress, and optional systems such as spray or vacuum. These ensure lump-free mixes critical for braking efficiency, heat dissipation, wear resistance, and noise reduction.

It uniformly mixes complex formulations of asbestos-free or semi-metallic friction materials, including resins (phenolic, epoxy-modified), reinforcing fibers (aramid, glass, steel, mineral fibers), friction modifiers (graphite, molybdenum disulfide, ceramics), fillers (barytes, calcium carbonate), rubber compounds, and curing agents. It achieves consistent particle distribution, eliminates agglomerates, and delivers the required rheological properties.

Key advantages include superior batch-to-batch consistency and material uniformity, reduced mixing time with improved production efficiency, better flow characteristics during compression molding, lower scrap rates and fewer defects in finished brake pads, enhanced mechanical and tribological properties of the final product, and easier cleaning and maintenance between different formulations.

Optional features include a spray system, vacuum system, and other enhancements that increase process flexibility for adding liquids, removing air, or controlling product consistency during the preparation of friction compounds.
