QT6-15 Machine: Enhancing Paver Block Production

Understanding QT6-15 Hydraulic Paver Block Machine

The QT6-15 hydraulic paver block making machine is a state-of-the-art, fully automatic system engineered for the high-output manufacture of diverse concrete products. Renowned globally, it delivers exceptional paver blocks, hollow blocks, solid bricks, and curbstones, thanks to its sturdy construction, intelligent control system, and advanced hydraulic pressure technology.

Step-by-Step Guide: Producing Paver Blocks with QT6-15

Material Preparation

• Cement
• Sand
• Gravel or crushed stone
• Water
• Color pigments (for colored pavers)

The initial phase involves precise measurement and mixing of these components using a concrete mixer to ensure a consistent and uniform blend.

Feeding the Material

Post mixing, the material is transferred into the QT6-15's hopper. The feeding system, equipped with a ring belt, ensures the mix is evenly and efficiently delivered into the mold box, critical for maintaining block quality.

Molding Through Vibration

Distinct from traditional methods relying on hydraulic pressing, the QT6-15 utilizes high-frequency vibrations:

• The concrete mix is spread into the feeder car.
• Robust vibration motors create intense vertical vibrations.
• The vibrations compact and settle the material within the mold cavities.

Block Forming and Transfer

Once compaction via vibration is finalized:

• The mold, aided by a hydraulic system, lifts while the tamper head holds the blocks.
• As the mold ascends, the blocks are placed onto the pallet below and transferred smoothly to the conveyor or stacking system for further processing.

Curing Process

Freshly formed blocks are transported—typically by automated stacking systems—to a curing area, where they undergo:

• Initial curing lasting 24-48 hours
• Water curing to reach optimal strength

Curing is a vital step to ensure the blocks' durability and weather resistance.
