QTJ4-26C Cement Brick Block Making Machine

The QTJ4-26C is a semi-automatic concrete block and paver making machine designed to produce high-quality hollow bricks, hole bricks and interlocking pavers using mould vibration technology for improved density and finish.

By changing moulds the machine can produce hollow blocks, solid blocks, interlocking pavers, curbs and various hole bricks. Typical example sizes quoted include 400×200×200mm, 400×150×200mm and 400×100×200mm.

Production depends on block type and cycle time. Typical theoretical outputs per 10-hour shift are: 400×200×200mm — 4,000 pcs; 400×150×200mm — 5,600 pcs; 400×100×200mm — 8,800 pcs.

The moulding cycle is approximately 26–30 seconds per cycle, depending on material mix and operator efficiency.

Host machine rated power is 13.5 kW. The accompanying blender is 7.5 kW and the conveyor is 1.5 kW. Exact electrical supply requirements (voltage/phase) should be confirmed with the supplier based on your region.

Overall machine dimensions are 3200 mm × 2100 mm × 2350 mm (L×W×H). Host machine weight is 1.5 tonnes. Blender and conveyor have separate dimensions and weights (blender: 1300×1300×1100 mm, ~400 kg; conveyor: 800×320×6000 mm, ~300 kg).

The machine works with common concrete block raw materials including cement, sand, fly ash and ready-mix concrete. Material proportions and mix design should be optimized for desired strength and density.

The QTJ4-26C is designed to be efficient — typically 2–3 people are sufficient for production and transportation of finished blocks.

The machine is semi-automatic and equipped with a PLC and control system for consistent operation. Key actuators include vibration moulding, lifting and scraping systems; loading/feeding and curing are handled manually or with auxiliary equipment.

Moulds are changed manually; the machine is multifunctional so different moulds produce different block types. Changeover time depends on operator skill and mould complexity but typically ranges from 30 minutes to an hour.

Key components include a PLC, pressure vessel, engine/motor, pump and gearbox. Standard wearing parts are supplied with the shipment and the supplier provides after-sales support to facilitate faster spare parts replacement.

Regular maintenance includes daily cleaning of the mould and moving surfaces, routine lubrication of bearings and gearboxes, periodic inspection of hydraulic and vibration systems, and timely replacement of wearing parts. Follow supplier maintenance schedules for best performance.

The machine requires a flat, level and stable foundation (concrete recommended), adequate workshop space for operation and material handling, and appropriate power supply capacity for the host, blender and conveyor. Confirm exact electrical and foundation specs with your supplier.

Safety features typically include emergency stop controls, guarding on moving parts, and standardized electrical protections. Operators should receive training on safe operation, lockout/tagout, basic troubleshooting and routine maintenance from the supplier or trained personnel.

Warranty terms and after-sales services vary by supplier and region. The product description indicates spare parts and faster after-sales service are provided; contact your supplier or distributor for details on warranty coverage, replacement parts, installation assistance and operator training packages.
