Production Case of QT4‑15C Automatic Concrete Brick Making Machine (Focus on Standard Solid Bricks)

Project Overview

Machine Model: QT4‑15C Automatic Concrete Brick Making Machine

Main Product: Concrete standard solid bricks

Raw Materials: River sand, crushed stone, cement, stone dust. Fly ash, slag and other industrial waste can be added. Non‑firing, natural curing.

Production Capacity: Optimized vibration and feeding system for solid bricks. Output reaches 45000‑52000 standard solid bricks within 8 working hours. Equipped with automatic feeding and brick discharging to reduce labor cost.

Project Position: Supply building materials for civil construction and wall masonry. The customer takes standard solid bricks as core product. Hollow blocks, porous bricks, paver blocks and curb stones are available by changing moulds.

Site Introduction

The full‑set production line includes QT4‑15C main unit, batching & mixing system, aggregate bin, belt conveyor, hydraulic station and PLC control console. It adopts combined table‑mould vibration plus hydraulic pressing technology. Low‑frequency feeding and high‑frequency compaction make concrete material exhaust quickly. Solid bricks achieve high density right after demoulding and can be stacked directly, saving pallet investment.

Only 4‑5 workers are needed for batching, machine monitoring, finished‑brick handling and stacking. Fresh solid bricks are stacked for curing before delivery. Solid‑brick mould keeps installed for continuous mass production.

Advantages for Standard Solid Brick Production

1. High strength & regular appearance. Uniform exciting force ensures high density, small dimensional tolerance and low reject rate. Compressive strength meets masonry requirements.

2. High output for solid‑brick orders. Short molding cycle with large output per mould, well‑suited for medium‑small brick plants to fulfill bulk construction orders.

3. Wide raw‑material compatibility. Fly ash, slag and stone dust can be utilized to lower cost and realize solid waste recycling.

4. Stable for long‑time continuous running. Integrated hydraulic system with quality key components, specially optimized for high‑density solid brick production. Simple foundation and reasonable plant space requirement.

5. Multi‑function flexibility. Switch to produce hollow blocks, pavers, slope‑protection blocks by replacing moulds to adapt to market changes.

Customer Feedback

This customer mainly supplies standard solid bricks for local construction market. The qualified rate of solid bricks keeps above 96% after commissioning. The machine runs continuously with low failure rate. Produced solid bricks reach required hardness and satisfy large‑volume market demand. The client thinks QT4‑15C is cost‑effective for small‑and‑medium factories focusing on standard solid bricks and solves local building‑material supply demands.
