1. Heavy‑duty Gantry‑frame & Four‑column Guide Structure, Durable Frame & Less Unexpected Downtime
QTJ4‑40B2 adopts gantry‑style frame welded by high‑strength section steel, equipped with four vertical guide columns plus wear‑resistant sliding sleeves. The mold lifts and descends with precise guidance without offset or shaking. It withstands long‑time high‑frequency vibration and anti‑fatigue performance is excellent. With simplified mechanical design, it reduces risk of jamming and deformation, minimizing unplanned shutdown and securing stable small‑batch production.
2. Combined Upper‑lower Dual‑vibration System for Dense Blocks & Good Finished‑product Appearance
The machine is equipped with upper and lower vibrators working cooperatively. Lower vibrator runs during material feeding phase; both vibrators activate synchronously in forming stage. Vibration energy transfers fully into mold cavity to make aggregate flow sufficiently and exhaust trapped air bubbles. Finished hollow blocks and standard bricks feature dense texture and intact edges with low reject rate. Products meet procurement requirements for building walls and support you to win local small‑medium construction orders.
3. Flexible Mold‑change Design for Multi‑block Types, Responding to Diversified Small‑batch Orders
It supports pallet size 850×460‑550 mm. One molding cycle produces 4 pcs 390×190×190 mm hollow blocks or 21 pcs 240×115×53 mm standard bricks. Various hollow blocks & standard bricks can be manufactured simply by swapping molds. Mold disassembly, assembly and adjustment are user‑friendly, operators can finish mold replacement quickly. One single machine handles various small‑batch orders and improves your equipment return‑on‑investment without buying extra main machines.
4. Wide Raw‑material Compatibility, Utilize Local Aggregates & Residues to Cut Material Expense
This machine works well with sand, stone powder, pebble, crushed stone, fly ash, brick residue and other materials. You can take advantage of locally available aggregates and industrial waste, reduce cement dosage while keeping block quality. It only requires simple pre‑treatment for raw materials. Well‑suited for township workshops and construction‑site projects with abundant local raw‑material resources.
5. Low‑entry Investment, Simple Supporting Configuration, Fast Commissioning & Easy Operator Training
Total machine weight is only 933 kg with compact dimension. It can be installed on ordinary hardened concrete ground without complicated foundation construction. A complete simple production line can be built by matching with JQ350 pan mixer with low overall project cost. Electric‑mechanical control logic is straightforward. Operators can get competent after short‑term hands‑on training, no high‑salary senior technicians required and saving labor cost, ideal for new‑start block‑making businesses.
6. Modular Shipment, Sufficient Spare‑part Supply & Controllable After‑sales Maintenance Cost
Modular split packaging facilitates sea‑container transportation. After on‑site positioning, leveling and power connection, simple commissioning enables trial‑production. Manufacturer provides guidance for mold replacement and production‑process operation. Wear parts including vibration motors, springs and mold accessories are continuously supplied. Component replacement can be finished by ordinary mechanics, no senior maintenance specialist required, keeping long‑term operation‑cost low.
