20000 Blocks Per Day Block Making Machine Line

Building a 20000 Blocks Per Day Block Making Machine Line

A 20000 blocks per day block making machine line is a two-shift factory, not a scaled-up yard. It needs a mid-size host machine, a belt-rack curing line that can hold and return thousands of pallets a day, and a double-station cuber so the flow never waits at the end of the line. The configuration is different in kind from a 10000-block plant, not just larger in number.

At this output, the constraint moves from the press to the material supply and the pallet loop. The host machine is rarely the bottleneck. Batching that cannot keep the mixer full, or a curing area that returns pallets slowly, will cap a 20000-block plant at 13,000 or 14,000 pieces and nobody notices until the monthly totals come in.

• Host machine: QST1200 fully automatic block machine, with QST1500 for higher single-machine output.
• Stated host output: up to 120,960 standard bricks per 8-hour shift on the QST1200.
• Curing: QSDJ belt-rack curing line with a lithium-battery transfer car and 485 wireless networking.
• Cubing: QS-1000G-C double-station cuber, about 3,800 pallets per shift.
• Host footprint: QST1200 measures 11,500 x 4,550 x 2,800 mm at 17 t.
• Packing: QSSX-16A top-rotary baler or the QS cantilever wrapper for a closed pack.

Line Flow for a 20k/day Plant

At 20000 blocks per day the line runs continuously and the pallet loop carries real volume. Each stage must be sized for two shifts of steady work.

1. Aggregates are weighed by the PL Series batching machine, sized to the QST1200 cycle so the mixer never waits for a batch.
2. The batch is mixed in the CMP vertical shaft planetary mixer, which keeps turnout uniform on short cycles.
3. The QST1200 moulds the products on a 1,350 x 880 x 25 mm pallet with a cycle of 15 to 25 seconds.
4. Loaded pallets transfer into the QSDJ belt-rack curing line. A lithium-battery transfer car moves stacks to and from the curing racks, and a self-organised RS-485 wireless network links the line to cloud remote monitoring.
5. Cured products reach the QS-1000G-C double-station cuber, which runs two-way cubing on the left and right to lift line efficiency, at about 3,800 pallets per shift.
6. Finished cubes are strapped or wrapped, then handled to the yard or straight onto a truck.

Equipment List and Configuration

The QSDJ line matches a host machine of any manufacturer and any model, so a plant can add the curing line around an existing press without replacing it. See the concrete block production line range for how these stages connect.

Capacity Assumptions

Two shifts change the arithmetic. The host figure is per shift, so a two-shift plant doubles the daily ceiling, but only if batching, curing and packing carry the second shift without extra downtime. A hollow block carries fewer pieces per mould than a thin brick, so the block count for a 390 x 190 x 190 mm product is lower than the standard-brick figure. Confirm your own piece count with the block machine capacity guide.

How a 20k/day Line Differs From a 10k/day Line

The difference is not a bigger number on the same list. The larger line carries a different curing technology, a double-station cuber, automatic packing and a bigger batch plant, and it is planned for two shifts from the start.

Factory Requirements

Area

A 20k/day plant needs more curing volume than a compact line, because pallets spend hours curing while the host keeps making new ones. The QSDJ rack-curing design stores each layer on an isolated rack level and uses building height, which holds the ground footprint down. The QS-1000G-C double-station cuber covers about 19,000 x 7,500 x 5,500 mm, and the batching plant and aggregate yard need room for two shifts of consumption.

Power

The driven load is roughly the host plus the cuber plus batching and packing. Reference values: QST1200 host 57.6 kW, QS-1000G-C cuber 44 to 45 kW, QSSX-16A baler about 5 kVA, QSPY-16A baler 2 kW. Equipment is built for a 380 V three-phase supply, and the QSDJ transfer car runs on a new-energy lithium battery with wireless control and an automatic charging pile. Size the transformer to the total installed load plus a margin, and plan for two-shift duty, not peak-only.

Water and Foundation

Water is for mixing and for curing moisture, sized from your mix design and two-shift batch count. The QST1200 host weighs 17 t and vibrates; its foundation must carry that weight with dynamic loading on stable ground. Release foundation drawings before shipment so concrete work runs during transit.

Manpower

The QSDJ line is automatic, so the crew is small relative to the tonnage moved, but the exact number follows the finished-goods and packing scope you select. With two shifts the same small crew runs twice, and the operating skill concentrates in the PLC, the wireless transfer control and the mould change.

Cost Factors

No price is quoted here, because a figure only exists once the configuration is fixed. These are the variables that move a 20k/day budget.

• Host size. QST1200 against QST1500, which carries a heavier frame and higher installed capacity.
• Curing technology. A belt-rack line with a lithium transfer car and wireless monitoring carries more control and battery content than a single-layer layout.
• Cuber. The double-station QS-1000G-C costs more than a single-station cuber but removes a flow limit at the end of the line.
• Pallet count. Two shifts and a large curing volume multiply the pallet requirement.
• Packing. A strapping baler or a cantilever wrapper adds equipment and removes manual handling.
• Batching and mixing. Larger dosing capacity is needed to feed a two-shift host.
• Site works and freight. Foundations, buildings, incoming power, container count and site conditions are the buyer scope.

Delivery and Installation

A 20k/day line is a project with a defined sequence, and the curing line is the long pole.

1. Confirm the configuration and site conditions, then freeze the drawings and release foundations.
2. Install batching and mixing, then set the QST1200 host on its foundation and level it to the pallet line.
3. Assemble the QSDJ curing racks, the transfer car track and the charging pile, then align the transfer points.
4. Install the QS-1000G-C double-station cuber and the packing equipment, and connect them to the control system.
5. Run the whole loop on real mix across both shifts, then train the crew on the control system, the wireless transfer and the mould change.
6. Agree the wear-parts list and the two-shift maintenance routine before handover.

Plan for two shifts from day one, including staffing and spare pallets, or the second shift will arrive without the support it needs. For regional demand and power habits, see the Syria market page, and when you are ready Get 20k/day Plan with your block sizes, shift plan and site area.
