QT4‑25C Automatic Concrete Block Forming Machine Overseas Production Case

1. Project Overview

Equipment Model: QT4‑25C Fully‑automatic Hydraulic Block Forming Machine

Project Location: Brick factory site in East Africa

Production Products: Standard hollow blocks, solid concrete bricks, paving bricks, interlocking bricks, curb stones, perforated blocks

Process Raw Materials: Sand‑stone aggregate, crushed stone, ordinary Portland cement, fly ash, slag, construction waste recycled aggregate, industrial waste residue, mineral color pigment

Equipment Configuration: Forming main machine, hydraulic power unit, PLC automatic electric control system, automatic pallet feeding mechanism, belt feeding conveyor, brick output station, compatible with batching mixing station and cement silo

2. Project Site Introduction

This is a commercial brick‑making plant in East Africa with semi‑open production yard. After installation and commissioning, QT4‑25C block machine was put into continuous mass production. The batching‑mixing unit works cooperatively with the forming host.

Proportioned raw materials are delivered to machine silo by belt conveyor. Bricks are shaped by hydraulic‑vibration compaction and automatically discharged onto pallets. Fresh blocks and pavers with neat edges are stacked on site for natural curing. Local workers carry pallets and load finished bricks onto trucks. Finished products supply local residential buildings and municipal infrastructure projects. Feeding, distributing, pressing and brick‑discharging run automatically, only few workers are required for auxiliary work. Local sand‑stone and industrial residues can be utilized to cut material cost.

3. Core Equipment Advantages

① Hydraulic & High‑frequency Vibration Composite Molding

Powerful hydraulic pressure plus high‑frequency vibration ensures high compaction, stable brick strength and precise dimension. Low reject rate for large‑volume commercial production.

② High Output for Mass Production

Stable production cycle delivers large capacity for medium‑small brick plants. Quick mold change supports hollow blocks, solid bricks, interlocking pavers and curb stones, diversifying product portfolio and market competitiveness.

③ Broad Raw‑material Compatibility

Local sand, stone and cement serve as basic materials. Fly ash, slag and recycled construction waste can be mixed into formula. Color pigments are available for colored paving bricks, reusing local waste resources and lowering material expenditure.

④ PLC Automatic Control System

Pallet feeding, material distributing, pressing and brick discharging are fully automatic. Operation logic is user‑friendly. Local workers can master operation after short‑term training.

⑤ Heavy‑duty & Durable Structure

Reinforced frame adapts to dusty outdoor African working conditions. Few wearing parts and low failure rate simplify maintenance for long‑term continuous operation overseas.

4. Customer Evaluation

The customer is satisfied with stable mass‑production performance of QT4‑25C. High output meets large demand of hollow blocks for local housing construction. Various products can be obtained by replacing molds to win more municipal orders.

The machine makes good use of local sand‑stone and waste materials to save production cost. High‑automation reduces labor requirement. Robust structure suits outdoor site environment with low failure rate. Local staff can handle daily operation and simple maintenance independently. The customer considers QT4‑25C as a cost‑effective brick‑making solution for commercial medium‑small brick factories in East Africa.
