QT4‑15B Automatic Hydraulic Brick Making Machine Production Case for Concrete Hollow Blocks
Production Case of QT4‑15B Automatic Hydraulic Brick Making Machine
Project Overview
Machine Model: QT4‑15B Automatic Hydraulic Brick Making Machine
Main Product: Concrete hollow blocks
Raw Materials: Crushed stone, river sand, cement, stone dust. Non‑firing, cured under natural temperature.
Production Capacity: 4 hollow blocks per cycle. Output reaches 2800‑3200 pieces within 8 working hours. Equipped with automatic feeding and brick discharging system to reduce labor intensity.
Project Position: Manufacturing non‑load‑bearing wall blocks for civil buildings, fences and low‑rise construction. The customer takes hollow blocks as core product, and solid bricks, curb stones can be produced by changing moulds.

Site Introduction
The complete production line consists of QT4‑15B main machine, aggregate bin, belt conveyor, hydraulic station and PLC control console. It adopts combined forming technology of hydraulic pressing and high‑frequency vibration. The vibrating table compacts mixture materials, ensuring full filling inside hollow blocks and high density to avoid cracking.
Only 3‑4 workers are required for batching, machine operation, pallet handling and finished block stacking. Fresh wet hollow blocks on pallets go through natural outdoor curing and reach usable strength in 7‑10 days. The hollow‑block mould keeps installed on machine for continuous mass production.
Advantages for Hollow Block Production
1. Stable finished quality: Cooperation of high‑frequency vibration and hydraulic pressing brings neat cavity shape, uniform wall thickness and low reject rate.
2. Suitable capacity for hollow‑block market: Multiple hollow blocks per cycle, ideal for mass production in small‑medium brick plants to supply wall materials for construction sites.
3. Wide raw‑material adaptability: Stone dust and mining waste can be utilized to cut cost and realize solid waste recycling.
4. Cost‑effective investment: Small occupation area and simple foundation work, perfect for investors focusing on hollow block production.
5. Flexible multi‑function: Produce solid bricks, porous blocks and slope‑protection bricks with different moulds for business expansion.
Customer Feedback
This customer supplies hollow blocks to local construction market. The qualified rate of hollow blocks remains above 95% after commissioning. The hydraulic system works stably with low failure rate. Output hollow blocks have light weight and good heat‑insulation & sound‑insulation performance, enjoying good market sales. The client thinks QT4‑15B is cost‑effective for small‑and‑medium brick factories focusing on hollow blocks, which can meet large‑volume supply demands for local wall blocks.
