QTJ4-40A
HS
The QTJ4-40A is a semi-automatic concrete block making machine designed for small and medium-sized block manufacturers. Equipped with a JW350 concrete mixer, belt conveyor, and feeding system, it simplifies material preparation and transportation, reducing manual handling throughout the production process.
With a total power of 9.6 kW, an excitation force of 48 kN, and a molding cycle of 60–70 seconds, the QTJ4-40A supports the production of hollow blocks, solid bricks, standard bricks, and concrete paving blocks through compatible molds.
Whether you are starting a block manufacturing business or expanding your existing production, QTJ4-40A provides a practical equipment combination for your business needs.
Beyond machinery, HS offers customized block molds, local raw material mix guidance, installation assistance, and after-sales support to help you move from equipment purchase to actual production.
Unlike a basic manual block making machine, the QTJ4-40A comes with supporting mixing and conveying equipment to simplify the material preparation process.
The JW350 mixer prepares the concrete mixture, while the belt conveyor transfers the mixed material toward the machine's feeding area. Together with the feeding arrangement, these components help reduce manual material handling and make the production workflow more organized.
For small block manufacturers, this provides a practical way to improve material handling without investing in a large fully automatic production line.
The JW350 mixer provides a dedicated mixing solution for preparing concrete materials before block forming. It helps achieve a more organized material preparation process and supports your daily production operations.
Your Benefit: Reduce manual mixing work and prepare concrete mixtures more conveniently for block production.
The belt conveyor transfers the prepared concrete mixture from the mixing area toward the block making machine's feeding position, reducing the need for manual material transportation.
Your Benefit: Make material transfer easier and reduce repetitive handling between production stages.
The feeding hopper provides a designated material receiving and feeding arrangement for the block forming process, helping coordinate material delivery to the machine.
Your Benefit: Support a more organized feeding process and improve coordination between material preparation and block forming.
With the mixer, conveyor, and feeding arrangement working together, QTJ4-40A offers a more convenient semi-automatic production setup for small block manufacturers.
