CPLN-1.5 Planetary Concrete Mixer

CONSTMACH's 1.5 cubic meter planetary concrete mixer represents a significant advancement in high-performance mixing technology for the concrete production industry. This machine delivers exceptional mixing efficiency through its sophisticated planetary design, where rotating mixing arms follow a dual-motion pattern that ensures complete coverage of the mixing pan floor. The result is a mixer that consistently outperforms conventional designs while maintaining the reliability demanded by modern concrete production facilities.

The planetary mixing principle sets this equipment apart from traditional twin-shaft or turbine mixers. Two three-armed mixing stars rotate on their own axes while simultaneously orbiting around the pan's center point. This countercurrent movement creates an intensive mixing action that thoroughly processes even zero-slump concrete mixes in remarkably short cycles. After water addition, most concrete types reach optimal homogeneity in 30 seconds or less. This rapid processing capability directly translates to increased plant throughput without requiring larger equipment footprints or additional energy consumption.

CONSTMACH has engineered this 1.5 model with a charging volume of 2,250 liters, producing 2,000 liters of fresh concrete per batch. The compacted output reaches 1,500 liters, providing substantial production capacity for medium to large-scale operations. Dual 30 kW motors drive the system through a large-capacity reduction gearbox submerged in an oil bath for superior cooling performance. This configuration runs considerably cooler than compact commercial gear units found in competing designs, which often struggle with heat buildup during continuous operation. The gearbox carries a comprehensive 5-year or 10,000-hour guarantee, reflecting the manufacturer's confidence in its durability.

The mixer's pan volume exceeds many competitors rated for similar output by up to 30 percent. This generous capacity ensures the unit handles full-rated loads without strain while maintaining consistent mixing quality across varying batch sizes. The three-armed star configuration provides superior mixing action compared to two-arm alternatives and demonstrates extended service life. Each arm features 25mm Ni-Hard mixing blades that resist abrasive wear from harsh aggregates, while the pan floor incorporates individually replaceable 10mm Hardox 450 tiles. Side body protection comes from 10mm ST-52 steel plates. For extreme wear applications, chromium carbide cladded components are available, and rubber blades can be specified when processing particularly aggressive materials.

The planetary motion creates a powerful countercurrent flow that achieves higher concrete strength values while reducing cement requirements by 10 to 15 percent compared to conventional pan or drum mixers. This efficiency gain impacts both product quality and operational costs. The mixing arms perform the actual homogenization work, meaning the mixer delivers consistent results on both full batches and smaller partial loads. Discharge paddles serve only to move material out of the pan rather than contributing to the mixing process itself.

Discharge occurs through hydraulically operated rubber-sealed doors that eliminate water leakage issues common with mechanical door systems. The hydraulic mechanism provides precise control during opening and closing cycles, and up to four discharge points can be configured based on plant layout requirements. Complete cleanout happens naturally through the discharge doors without needing additional mechanisms or manual intervention. The motors and gearing can handle occasional startup under full load without hydraulic coupling assistance, though this practice isn't recommended for regular use.

Access for maintenance and cleaning comes through a large half-moon cover that opens safely and quickly. A high-security locking latch physically prevents startup when the cover is open, providing a fail-safe mechanism that protects operators even if lockout procedures are inadvertently bypassed. All electrical wiring meets UL standards, and motors carry CE certification with UL approval available upon request. This attention to safety standards makes the mixer suitable for installation across different regulatory environments.

CONSTMACH's planetary mixer excels particularly in dry-cast concrete applications where its intense mixing action breaks up stiff, zero-slump mixes that challenge other mixer types. The combination of rapid cycle times, reduced cement consumption, superior concrete strength, and minimal maintenance requirements positions this equipment as an excellent value proposition in its category. Production facilities seeking to maximize output quality while controlling operating expenses will find this 1.5 cubic meter planetary mixer delivers measurable performance advantages over alternative mixing technologies.
