Non‑Vacuum vs Vacuum Brick Extruder: How to Choose Equipment for Your Brick Yard

When overseas buyers plan to purchase brick making equipment, one of the most frequently raised questions is whether to invest in vacuum brick extruder or non‑vacuum brick extruder. Both types of brick machines serve fired brick production, yet they differ greatly in price, power demand, production output and applicable working scenarios.

Many brick‑plant investors fall into the misunderstanding that vacuum brick machines are always the only good option. In fact, vacuum extrusion systems add vacuum chambers, which push up equipment cost and power consumption. For many small‑to‑medium brick yards producing standard solid fired bricks, non‑vacuum extruders can deliver fully qualified brick products with much lower overall investment.

Before making purchasing decisions, plant owners need to evaluate their own real‑world conditions: project budget, target brick types, local power supply situation, available raw materials and kiln style. If your main product is standard solid bricks and your budget is limited, a high‑quality non‑vacuum brick machine deserves serious consideration.

The JZ series non‑vacuum brick making machine is a mature multi‑model product line targeting global small and medium brick‑yard projects. Model portfolio covers JZ250, JZ280, JZ300, JZ350, JZ400. Production capacity ranges 7.5 t/h‑25 t/h, auger diameter from 250 mm to 400 mm. Power configuration scales from 11 KW up to 55 KW. Only JZ250 adopts manual brick cutting unit; other models are equipped with independent brick cutting machines.

Key strengths of JZ series:

🔹 Multi‑raw‑material tolerance: Process clay, red soil and fly ash effectively, giving brick factories flexibility to use locally accessible raw resources.

🔹 Economical power performance: The JZ300 model runs at merely 30 KW extruder power, bringing down daily electricity cost for continuous brick production.

🔹 Simple operation & maintenance: Manual clutch structure simplifies operation procedures for on‑site workers, reducing training cost.

🔹 Brick production flexibility: Mainly for high‑quality solid bricks, capable of small‑hole hollow brick output. For large‑hole hollow brick manufacturing, higher‑power vacuum extruder is recommended.

🔹 Compatible with Hoffman kiln: Perfectly matched with Hoffman kiln firing process, widely adopted in Africa, Central Asia and Southeast Asia small brick projects.

FAQ

Q1: What is the difference between non‑vacuum and vacuum brick extruder?

 A: Vacuum extruder adds vacuum de‑airing structure for higher brick density, with higher cost and power. Non‑vacuum type features lower investment, suitable for standard solid fired brick production.

Q2: Can JZ series brick machine work with Hoffman kiln?

 A: Yes, JZ series non‑vacuum brick extruder is highly compatible with Hoffman kiln for solid brick production.

Q3: Which JZ model should I pick for my brick workshop?

 A: Confirm your target hourly output, local power supply and brick types. We offer JZ250‑JZ400 multiple options for different‑size brick yards.
