Production Case of QTJ4‑26 Semi Automatic Hydraulic Block Making Machine

Equipment Model：QTJ4‑26 Semi Automatic Hydraulic Block Making Machine

Project Location：Domestic brick‑manufacturing plant workshop

Main Block Types：Mainly produces road curbs. By changing molds, it can also produce paving bricks, permeable bricks, hollow blocks, standard bricks and other concrete products. 4 blocks can be formed per cycle. With sufficient forming pressure, finished curbs have complete edges and high compactness, widely applied in municipal roads, residential parks and road edge projects.

Raw Materials：Crushed stone, manufactured sand, stone powder and ordinary Portland cement, mixed with water in required proportion. Raw materials are easy to obtain; stone tailings can be utilized. Green bricks adopt natural curing. Steam curing system is optional to shorten curing cycle and accelerate production turnover.

Project Description

The customer purchased a complete production line based on the QTJ4‑26 semi‑automatic block forming main machine, including batching & mixing system, automatic pallet elevator‑stacker and pallet conveying system. Mass production of road curbs started after installation and commissioning.

Production Process: Automatic batching and mixing of aggregates and cement → Semi‑automatic feeding and distributing (host operation) → High‑frequency vibration and hydraulic pressure molding → Green bricks discharged with pallets → Multi‑layer stacking by automatic pallet elevator‑stacker → Forklift transfers stacked pallets to curing area for natural curing → Qualified finished curbs delivered for local municipal road projects.

The optional automatic stacking equipment greatly reduces manual handling work. Only a few workers are required for inspection and pallet transfer. Featuring small footprint and reasonable investment, the QTJ4‑26 semi‑automatic brick machine is well‑suited for small‑and‑medium brick factories focusing on municipal curbs and paving products.

Main Equipment Advantages

1. Economical & cost‑effective: 4 pieces per molding cycle with stable rhythm. Low investment for equipment and plant, ideal for new medium‑small brick plant projects.

2. High forming pressure for large‑size products: Powerful hydraulic pressing system ensures compact curb blocks with sharp edges, meeting municipal engineering strength requirements.

3. Optional automatic pallet elevator‑stacker: Realizes automatic stacking of green‑brick pallets, reduces labor intensity and improves workshop handling efficiency.

4. Flexible mold replacement: Quick mold change for road curbs, permeable bricks, paving bricks and hollow blocks to handle diversified orders.

5. Reliable electric‑button control for host machine: The supporting batching system can adopt automatic PLC control. The host completes feeding, molding and brick output under semi‑automatic cycle with electric interlock protection. Easy operation; workers can master operation after short‑term training. Robust hydraulic system enables simple daily maintenance.

6. Wide raw‑material adaptability: Stone powder and tailings can be used as raw materials to cut production costs.

Customer Feedback

The customer is satisfied with the complete production line centered on the QTJ4‑26 semi‑automatic block machine. The equipment runs stably for mass‑production of road curbs. The finished curbs meet the appearance and strength standards required for municipal‑project supply. The optional automatic stacking system saves substantial manual labor. Thanks to its multi‑mold compatibility, various concrete products can be manufactured. The customer plans to purchase permeable‑brick molds at a later stage to expand its product portfolio and win more municipal and landscape‑engineering contracts.
