HAWEN QT12-15 Block Making Plant Shipped to Client in Algeria

In late September 2026, HAWEN Machinery shipped one QT12-15 Automatic Block Making Plant to China Harbour Engineering Company Ltd. (Algeria Branch) for a port construction project in Algeria. The line is configured for double-layer Zigzag Pavers and is expected to arrive at the Port of Algiers in early November 2026.

Customized Production Line for an Algeria Port Construction Project

This project was supplied for China Harbour Engineering Company Ltd. (Algeria Branch), supporting concrete product manufacturing for a port construction project in Algeria. The required product is a double-layer Zigzag Paver with a finished size of 225 × 112.5 × 100 mm.

To match the customer's product requirements, HAWEN configured the production line with a QT12-15 main block making machine, Face Mix Device, PL1600-III batching machine, MP1000 planetary concrete mixer, customized moulds, automatic pallet feeding and wet block handling equipment.

The complete shipment reflects HAWEN's ability to provide not only individual machines, but also a coordinated block production solution based on product size, mould capacity, concrete preparation and site application.

Integrated QT12-15 Plant for Zigzag Paver Manufacturing

The QT12-15 serves as the main forming machine, while the batching, mixing, feeding, moulding and product handling systems work together to form a continuous production process.

The PL1600-III batching machine proportions aggregates according to the selected mix design. The MP1000 planetary mixer then prepares concrete with stable mixing quality before material enters the forming stage.

For double-layer paver production, the Face Mix Device feeds the surface layer and base layer separately. An automatic feeding cart delivers concrete to the mould shoe in sequence, allowing the machine to form pavers with clear surface and base layers.

Stable Forming, Accurate Control and Reliable Compaction

The QT12-15 hydraulic station incorporates Japanese YUKEN proportional and directional valves together with an American ALBERT hydraulic pump. These components support coordinated movement of feeding, moulding and pressing mechanisms during each production cycle.

The machine adopts a 6-shaft vibration box design with eccentric blocks positioned outside the housing. Proper coordination of vibration, pressing parameters, concrete mix and mould structure helps achieve consistent compaction and repeatable product formation.

The SIEMENS S7-200 PLC control system and touch panel allow operators to manage production settings efficiently. Where remote monitoring is configured, operating information can also support technical troubleshooting and service response.

Designed for 30 Pieces of Zigzag Pavers per Mould

The customized mould is designed for Zigzag Pavers measuring 225 × 112.5 × 100 mm, with 30 pieces formed per cycle. Accurate mould design helps maintain product dimensions, edge quality and stable production performance.

HAWEN manufactures moulds compatible with various leading block machine brands, including MASA, HESS, ZENITH, POYATOS, BESSER, TIGER, Columbia, Quadra and OMAG. Mould hardness and material configuration are selected according to production requirements and machine conditions.

The 1350 × 950 mm GMT pallets provide reliable support during forming and product transfer, helping the customer maintain stable handling throughout the production process.

Careful Loading for Overseas Infrastructure Project Delivery

The HAWEN QT12-15 Automatic Block Making Plant was shipped in late September 2026 and is expected to arrive at the Port of Algiers in early November 2026. Each equipment module was organized according to loading sequence, container space and protection requirements.

For this port construction project, HAWEN matched the forming machine, mould, concrete preparation equipment, Face Mix Device, pallet system and handling equipment to the customer's intended concrete product. This integrated approach helps reduce coordination difficulties and supports efficient project implementation after arrival.

Supporting International Concrete Product Manufacturing Projects

Founded in 2009, HAWEN Machinery specializes in concrete block making machines, brick making machines, concrete moulds and complete production equipment for concrete products.
