JKB40/40 Double Stage Vacuum Extruder for Medium Scale Brick Production Line

JKB40/40 vacuum brick extruder is upgraded medium-output double-stage extrusion equipment, positioned between compact JKR30/30 small brick machine and JKB45/45 large extruder, tailor-designed for medium-size new brick plants and old brick factory renovation across global developing markets. Adopting mature dual-layer deaeration extrusion technology, it completes raw material mixing, crushing, vacuum deairing and mud strip forming in one unit, producing dense solid bricks, perforated bricks and big hollow bricks steadily.

Wide Raw Material & Finished Brick Application

This extruder fits diversified low-cost local raw materials: natural clay, shale, coal gangue, fly ash, mine tailings, cinder, bentonite mud, no strict requirement on raw soil composition. It supports customized moulds to produce standard solid bricks, multi-hole perforated bricks, wall hollow blocks, paving bricks, refractory bricks, widely used in construction building materials, rural brick manufacturing, waste residue recycling projects in Nigeria, Kenya, Ghana, India, Myanmar, Bangladesh.

Core Machine Advantages

Balanced productivity & cost: Hourly output 8000~10000 standard bricks, higher efficiency than JKR30/30 (4000-6000pcs/h), lower investment & power consumption than heavy JKR45/45 large extruder, optimal ROI for medium investment brick factory；
High vacuum & strong extrusion: Stable vacuum degree ≤-0.092MPa, forming pressure up to 2.5MPa, mud blank compact, low breakage rate after cutting and firing；
Durable wear-resistant structure: Screw auger with wear-resistant surfacing treatment, main shaft, gearbox via quenching & tempering aging process, hard tooth surface reducer, service life 3-5 times longer than ordinary cast parts；
Easy installation & maintenance: Compact integrated body, no need for complicated concrete foundation bolts, quick on-site assembly, spare parts universal and easy sourcing overseas；
Energy-efficient design: Matched total driving power 160~170KW, optimized spiral lead design cuts idle power loss, saves 20% running cost vs outdated old-type extruders。

Matching Full Brick Production Line Configuration

We can configure full supporting equipment per customer’s budget: box feeder → roller crusher → double-shaft mixer → JKB40/40 vacuum extruder → automatic brick cutter → brick unloading machine, semi-auto layout optional for small-medium brick plant.
