CPM-1 Pan Type Concrete Mixer

CONSTMACH's CPM-1 pan type concrete mixer represents a practical solution designed specifically for low to medium capacity concrete batching plants. This 1,500-liter charging capacity mixer stands out with its straightforward engineering approach that prioritizes operational reliability and minimal downtime. When you're running a concrete production facility, equipment that combines efficiency with easy maintenance becomes essential, and this is exactly where the CPM-1 delivers its strongest value proposition.

The mixer's core design philosophy centers on durability and protection. At the heart of the system lies a spring-loaded central arm fixation mechanism that acts as a safeguard against operational stress. During mixing operations, encountering oversized aggregates or unexpectedly hard materials isn't uncommon in real-world conditions. The integrated spring system absorbs shock loads and protects the mixing arms from potential damage, significantly extending component life and reducing unplanned maintenance interventions. This protective feature alone can save considerable costs over the equipment's operational lifespan.

Material selection plays a crucial role in the CPM-1's longevity. The mixing arms and scrapers utilize NiHard4 alloy, a nickel-chromium cast iron known for exceptional wear resistance in abrasive environments. These 25mm thick NiHard wearing plates maintain their mixing efficiency far longer than standard steel alternatives. The side body incorporates 10mm Hardox 450 plates, providing excellent impact and abrasion resistance, while the bottom section uses 10mm St 52 structural steel for robust foundation support. This combination of materials minimizes operating costs since replacement intervals extend considerably compared to mixers using conventional wear components.

The CPM-1 processes materials through three distinct volume specifications: 1,500 liters charging volume, 1,250 liters fresh concrete output, and 1,000 liters compacted concrete volume. A 37kW motor provides sufficient power for thorough mixing action across various concrete mix designs. The hydraulic discharge door system enables smooth, controlled material release, improving cycle times and reducing concrete waste. Operators benefit from quick batch turnover without manual intervention in the discharge process.

Safety and maintenance accessibility receive careful attention in the CPM-1's design. An emergency stop button provides immediate shutdown capability when needed, meeting essential workplace safety standards. The maintenance access hatch allows technicians to inspect internal components without extensive disassembly, reducing service time and keeping the mixer in production longer. A safety switch on the maintenance door prevents accidental operation during service work, protecting personnel. The mixer's bearing system uses heavy-duty components from SKF or FAG, both recognized globally for quality and reliability in industrial applications.

Pan mixers like the CPM-1 suit operations where straightforward maintenance procedures matter as much as mixing performance. The simple structural design means fewer complex components that could fail, and when service is required, technicians can complete work efficiently. For concrete producers operating compact batching plants or those requiring dependable equipment without complicated support requirements, this mixer configuration offers genuine practical advantages that translate directly into lower total cost of ownership and consistent production capability.
