4-28 is aconcrete semi-automatic paving block making machine powered by diesel engine.

Function

This machine can produce a various concrete hollow/solid block, paver by changing moulds.

Production efficiency

For 400*150*200mm, 4-28 can produce 3000cps/8h. For 240x115x53mm solid block, it can produce 14400pcs/8h.

Advanced technology

Hydraulic pressure moulding technology is adopted by this machine, so the brick machine has more stable and higher-efficiency working status and the bricks produced are of better quality, larger density and higher strength.

High-quality mould

Our brick moulds are made of 16# manganese steel. Besides the good raw material, Precise line cutting technology and 900 ℃ carburizing heat treatment technology are all adopted in the process of the brick mould production. Thus the brick moulds have better performance and longer service time. And the bricks produced are of higher quality
