CONSTMACH's CPM-2 pan type concrete mixer represents a practical solution for production facilities where moderate output capacity meets the demand for durability and operational efficiency. This mixer model has earned its place particularly in low to medium capacity concrete batching plants, where its straightforward design philosophy translates into real-world benefits for operators who value both performance and maintainability.
The CPM-2 comes equipped with a charging volume of 3,000 liters, producing 2,500 liters of fresh concrete and 2,000 liters of compacted concrete per batch. This capacity range positions it as an ideal choice for projects that require consistent production without the infrastructure demands of larger industrial mixers. The unit operates with a robust 55 kW motor, providing sufficient power to handle various concrete mix designs while maintaining energy efficiency throughout extended production cycles.
What sets this mixer apart is its engineering approach to common operational challenges. The central arm fixation system incorporates a spring mechanism that acts as a protective buffer when oversized aggregates or foreign materials enter the mixing chamber. This design detail prevents costly arm breakages that can halt production and lead to expensive repairs, a feature that becomes particularly valuable in environments where aggregate quality control may vary. The protection system doesn't compromise mixing efficiency but instead ensures continuous operation even under challenging conditions.
Material selection for wear components demonstrates CONSTMACH's understanding of long-term operational economics. The mixing arms and scrapers utilize high-quality NiHard4 alloy, a material specifically chosen for its exceptional wear resistance in abrasive environments. This metallurgical choice directly impacts the bottom line by extending component life and reducing the frequency of replacement cycles. The side body wears plates consist of 12 mm Hardox 450, while the bottom plates use 12 mm St 52 steel, creating a layered defense against the constant abrasion inherent in concrete mixing. The mixing arm wear plates feature 25 mm Ni-Hard material, providing enhanced durability at the most critical contact points.
Maintenance accessibility receives careful attention in the CPM-2's design. The structure allows technicians to reach key components without extensive disassembly, which translates to shorter maintenance windows and reduced downtime. This straightforward architecture means that routine inspections and part replacements can be performed by on-site personnel without requiring specialized external service teams, a significant advantage for operations in remote locations or those working under tight production schedules.
Safety features integrate seamlessly into the operational framework. The emergency stop button provides immediate shutdown capability, while the maintenance door safety switch prevents accidental operation during service procedures. These aren't merely compliance checkboxes but functional elements that protect both personnel and equipment. The access hatch facilitates internal inspection and cleaning, ensuring that quality control processes can be maintained throughout the mixer's service life.
The bearing selection further underscores the commitment to reliability. SKF and FAG brand heavy-duty bearings handle the rotational loads and operational stresses, components chosen for their proven track record in demanding industrial applications. The hydraulic discharge door system enables controlled material release, contributing to precise batch management and clean transitions between production cycles.
CONSTMACH's pan mixer technology reflects an understanding that equipment reliability directly influences project timelines and profitability. The CPM-2 serves operations where dependable performance, manageable maintenance requirements, and reasonable operational costs converge to support successful concrete production across various project scales and site conditions.
