QT4-25 Automatic Cement Block Machine Overview

The QT4-25 automatic cement block machine is a mechanically driven concrete block machine capable of producing hollow blocks, interlocking blocks, curbstones, and plain pavers. However, it does not produce colored pavers due to the lack of a pigment feeding machine.

  • Production Capacity: 8-inch hollow blocks: 4 pieces per mold at a cycle time of 25 seconds, or 4,608 pieces per day.
  • Price Range: $9,600 to $25,000 USD, depending on number of molds and other configurations.
  • Pallet Specifications: Uses 880×550×22mm GMT brick pallets.

1. Versatile Block Production: The QT4-25 Automatic Cement Block Machine is capable of producing various block types, including hollow blocks, interlocking blocks, paver bricks, and curbstones, making it an ideal solution for diverse brick and block manufacturing needs.

2. High-Frequency Vibration System: Equipped with a high-frequency vibration motor with large amplitude and strong excitation force, this QT4-25 Automatic Cement Block Machine delivers uniform compaction, enhancing the density and durability of finished blocks.

3. Efficient Production Cycle: With a 25-second mould cycle, QT4-25 Automatic Cement Block Machine achieves high efficiency, producing up to 4608 pieces of 8-inch hollow blocks per day,making it an optimal choice for high-volume output.

4. Precision Mould Manufacturing: The QT4-25 block moulds are produced through CNC linear cutting for high accuracy and treated with high-temperature heat for hardness and wear resistance, resulting in a significantly extended mould lifespan.
