Su robusto marco de acero soldado alberga varios subsistemas clave que trabajan en conjunto:<\/p>\n El nombre del modelo \"QT4-18\" es un código que revela su capacidad central. En la nomenclatura estándar de la industria: Here are the key technical specifications that define its performance:<\/span><\/p>\n | Especificación | Detalle | Nota Importante:<\/strong> The “blocks per shift” figure is a theoretical maximum under ideal conditions. Real-world output depends on raw material quality, product type, and operational efficiency.<\/span><\/p>\n The term “full automatic” signifies a profound shift in plant operation. While the QT4-18 machine itself automates the moulding process, it is designed to be the centerpiece of a fully automated line. This line can include automatic batching, mixing, conveying, curing, and stacking systems. The PLC control is the cornerstone of this automation.<\/span><\/p>\n Block strength and finish are non-negotiable for market acceptance.

\nA: While the theoretical capacity is ~4,300 blocks\/8 hours, a practical, sustainable output for hollow blocks is between 2,800 and 3,500 blocks, accounting for mould changes, maintenance breaks, and material handling.<\/span><\/p>\n
\nA: For the core moulding process, 1-2 workers are sufficient to monitor the PLC, manage pallet flow, and perform basic checks. A complete plant with mixing and stacking may require 3-4 personnel per shift.<\/span><\/p>\n
\nA: Manual machines require constant physical labor for every cycle. Semi-automatic machines mechanize some steps (like vibration) but require manual feeding and block removal. The QT4-18 is fully automatic, running continuous cycles with minimal human intervention, leading to exponentially higher output and consistency.<\/span><\/p>\n
\nA: Yes, absolutely. The QT4-18 is well-suited for using fly ash, slag, or even certain types of construction waste. These materials can reduce costs and improve block workability, but mix design ratios must be tested for optimal strength.<\/span><\/p>\n
\nA: Moulds are purchased from your machine supplier or specialized mould makers to ensure perfect compatibility. Changing a mould involves loosening bolts, removing the old mould, positioning the new one, and re-aligning—a task trained operators can do in 30-60 minutes.<\/span><\/p>\n
\nA: A solid, level concrete foundation (approx. 300mm thick) is mandatory to absorb vibration. The total plant space needed, including area for raw materials, mixing, curing, and block storage, is typically a minimum of 1,500-2,000 square meters for efficient operation.<\/span><\/p>\n
