QT4-15B Automatic Block Making Machine Domestic Project Case

1. Project Overview

Equipment Model: QT4-15B Automatic Block Making Machine

Project Location: Municipal brick plant site in China

Production Products: Hollow blocks, standard bricks, eight‑hole bricks, paving bricks, grass‑planting bricks, curb stones

Process Raw Materials: Cement, river sand, crushed stone, stone powder, fly ash, cinder, coal gangue, industrial waste residue

2. Project Site Introduction

The customer is a local small‑and‑medium‑sized building‑material manufacturer. Driven by growing local infrastructure projects, there is strong market demand for concrete blocks and paving bricks. The client also intended to make full use of local industrial solid waste to cut raw‑material costs. A complete production line based on QT4‑15B full‑automatic block making machine was purchased, matched with JS500 mixer, belt conveyor, automatic pallet feeder and block stacker. After commissioning, the whole process including pallet feeding, material distributing, vibration‑pressing, demoulding and block discharging runs automatically. Molds can be changed rapidly to produce various building‑material products to satisfy diverse orders from construction and municipal‑road projects. High‑proportion solid‑waste addition realizes eco‑friendly brick production and lowers material expenditure.

3. Core Equipment Advantages

① Wide raw‑material adaptability and high solid‑waste utilization rate

Compatible with various sand‑stone materials and industrial residues. Fly‑ash proportion can reach up to 70%, making good use of industrial waste for eco‑friendly production. Multiple block types can be produced by replacing molds. One machine serves multiple purposes to save equipment investment and meet multi‑variety orders for small‑and‑medium‑size brick plants.

② PLC automatic control, integrated mechanical‑electrical‑hydraulic system

Equipped with PLC programmable controller integrating mechanical, micro‑electronic and hydraulic technologies. High‑level automation realizes full‑process production to reduce labor cost. Automatic and manual modes are optional for convenient commissioning and maintenance.

③ Patented vibration box for stable product quality

With patented vibration box, high‑frequency vibration combined with hydraulic pressing provides sufficient exciting force. Produced green blocks feature high compactness, regular dimension and qualified strength. Forming cycle is 15‑20 seconds for stable output.

④ Robust machine structure

Main frame adopts thickened steel welding for excellent vibration resistance. Core hydraulic and electric components ensure low failure rate. Wear‑resistant molds and easy‑maintenance design support long‑time continuous industrial production.

4. Customer Evaluation

The machine runs steadily after commissioning. Automatic operation cuts labor quantity greatly. Using fly ash and other residues significantly reduces raw‑material cost. Mold replacement is simple, so the factory can switch among different products for market orders flexibly. Finished blocks have qualified strength and precise dimension, selling well in local market. On‑site installation, commissioning and technical training are satisfying with timely after‑sales support. The project brings fast investment return.
