NT7-10 Clay Brick Machine
The NT7-10 is our dedicated clay brick press for African and Southeast Asian markets where red clay bricks are still the dominant building material. While our QT4-40 and QT4-40A produce cement-bonded sandcrete blocks, the NT7-10 uses high-pressure mechanical compaction to turn raw clay soil into solid and hollow clay bricks that cure in the sun — no kiln required for the basic range. The 22 kW host delivers one 7-brick mould every 15 seconds, which means a single shift can produce 20,000 finished bricks.
What is Included in the NT7-10 Line

Why Choose the NT7-10
The NT7-10 is for buyers who already know they want clay bricks, not cement blocks. In much of West Africa, East Africa and South-East Asia, fired or sun-cured clay bricks are the default wall material — they are cheaper than cement blocks, they have better thermal insulation, and they require only soil from the building site. The NT7-10 turns that soil into uniform, sharp-edged bricks that sell at a premium in local markets.
Unlike the QT4-40 and QT4-40A which only produce cement-bonded blocks, the NT7-10 is purpose-built for clay. The 22 kW host, the 15-second cycle, and the 3,800 kg frame give it the compaction force needed to press raw clay into bricks strong enough to handle, stack and sun-cure without cracking. The included JQ750 mixer, clay crusher and vibrating screen form a complete material preparation line — the host receives clay that is already crushed, screened and mixed to the right moisture content.

30 Standard Brick Shapes Included
Every NT7-10 ships with reference moulds for 30 standard hollow clay brick shapes. The most popular in West and East Africa are #7, #8, #9 and #10 (red-outlined in the catalogue) — two-hole and three-hole load-bearing clay blocks in 300×150 and 150×150 formats. Special shapes (paver, diagonal, hourdis) are also covered.
