The QT4-40 is a compact, high-output semi-automatic block molding machine. Its model designation indicates a production capacity of 4 standard-sized hollow cement bricks (400*200*200 mm) every 40 seconds, resulting in a daily (8-hour) production capacity of 2880 8-inch hollow bricks.
Price is significantly lower than fully automatic lines, yet output is considerable, resulting in a short payback period. The normal price will be around $2800 for a set of hollow block making line, price list will vary a little based on different kinds of brick moulds.
Simple operation and maintenance.
Simpler structure than fully automatic lines, lower failure rate, lower maintenance costs, and less demanding on operators.
High product strength. Stronger vibration force and hydraulic pressure ensure the density and molding quality of the brick blanks.
Disadvantages:Still requires manual handling of cement bricks using trolleys, not achieving fully automated production line operation.Output limit is constrained by the manual handling speed and cannot be infinitely increased by increasing the cycle time like a fully automatic line.
During production, manual filling of raw materials and manual brick unloading/forklift transfer are required: the molded brick blanks, along with the pallet, are ejected, and then workers use manual trolleys to transport the stack of brick blanks to the curing area.
Main Components of the Production Line: A typical QT4-40 production line includes:
Main Machine – QT4-40 Block Molding Machine
Mixer: Typically equipped with a JS350 mixer, matching the main machine’s output.
Feeding System: Optional simple bucket feeder or handcart is used to lift and pour the mixed concrete into the main machine’s hopper.
Brick Unloading System: Relies on manual trolleys for transfer.
Cure Area: Used for stacking and natural curing of the brick blanks.
