1. Low‑entry‑cost Flexible Production for Small‑medium Paver‑brick Orders
QTJ4‑35B2 is developed for startup building‑material processors and small‑medium brick factories supplying municipal paving projects. Buyers can start business without huge upfront capital investment. It supports two working modes: standalone host operation, or simple production line combined with belt conveyor and JQ350 mixer. Customers can configure accessories step‑by‑step according to order volume and budget, instead of purchasing full‑line equipment at one time. Weighing only 1154 kg with dimension 1500×1660×2460 mm, the machine only requires flat hardened ground for installation. Production can run in simple workshop or open‑air shed, which greatly cuts civil‑construction costs. The 35‑second molding cycle delivers 2200‑2700 blocks per 8‑hour shift. Its proper output matches small‑scale paving‑brick projects and avoids overcapacity waste for new brick plants.
2. Combined Upper‑and‑lower Vibration for Dense Neat Pavers & Less Waste
Equipped with two 3 KW bottom vibrators plus one 1.5 KW upper‑die vibrator, the machine realizes combined table‑vibration plus head‑press vibration with 40 KN exciting force and 2800 rpm vibration frequency. For permeable bricks and interlocking pavers with strict requirement on corner compactness, compound vibration pushes concrete material fully into every corner of mould cavity. It effectively reduces common rejects such as loose corners, chipping and inner voids. Finished blocks feature uniform density and neat appearance, raising qualification rate and cutting raw‑material loss. Optimized vibration logic reduces abnormal mould wear and mould‑replacement frequency, saving consumable cost for plant owners. Produced paving and slope blocks reach acceptance standard for municipal landscaping and river‑protection projects.
3. Wide Raw‑material Compatibility, Utilize Local Solid Waste to Lower Paver Production Cost
QTJ4‑35B2 works well not only for conventional river sand, crushed stone, manufactured sand, but also for locally‑available industrial residues including stone dust, fly ash, cinder, slag and shale. Plant operators can replace expensive natural aggregates with low‑cost on‑site waste materials, greatly cutting expense on raw‑material purchasing and long‑distance transportation and improving profit margin of each paving brick. It adapts to ordinary concrete as well as lightweight concrete. Stable paver production can be achieved without complicated pre‑processing devices. It is an ideal option for factories near mining or thermal‑power plants to turn stock‑piled waste into salable paving building materials.
4. Multi‑mould Quick‑switching to Diverse Paving‑engineering Orders
Fitted with wear‑resistant manganese‑steel moulds, the machine can produce multiple building products simply by changing mould sets. Besides standard hollow blocks, it can make various permeable paving bricks, interlocking pavers, river slope‑protection blocks and landscape bricks. Factories can take mixed municipal, landscaping and slope‑protection orders with one single host, avoiding repeated investment on multiple machines. Mould replacement is user‑friendly. Operators can adjust product portfolio quickly following market demand and strengthen order‑receiving competitiveness. Custom non‑standard moulds are available for special local project specifications.
5. Low Operation Threshold, Controllable Labor Cost for Fast Mass‑production of Pavers
All lifting, discharging and vibration actions are controlled via central electric cabinet, without complex programming workflow. Built‑in upper‑die suspension positioning and automatic scrap‑removing mechanism reduce heavy manual work. General workers can master the full production cycle after short‑term training, no high‑salary professional technicians required. Only 1‑2 operators are enough for one production unit. Customers can launch formal paver supply business shortly after machine arrival, shortening the period from equipment receiving to commercial delivery.
6. Export‑oriented Complete‑set Solution & Reliable Foreign‑trade Delivery Support
The whole set including host, mixer and spare parts can be loaded into one 20ft container, simplifying sea shipment and customs clearance for overseas buyers. Basic scope covers main machine, hopper and spare parts. JQ350 mixer, belt conveyor and hand trolley are optional for complete simple production line. Trade term is FOB Qingdao. Multiple international payment options including TT and irrevocable sight L/C are supported. Goods will be delivered within 25 days upon deposit receipt and mould confirmation. One‑year full warranty takes effect after on‑site installation & commissioning. Mature procurement terms lower comprehensive purchasing risks for overseas small brick plants.
