Why choose QT8-15 Fully Automatic Cement Block Machine for Commercial Block Manufacturers
- The QT8-15 fully automatic cement block machine can produce up to 14,400 hollow bricks per day in a single shift, making it capable of handling large orders with ease. The pallet size has been increased to 950 × 900 mm, and the molding cycle is controlled at 15–20 seconds. In an 8-hour single shift, production can reach up to 14,400 hollow bricks, 40,000 colored paving bricks, and as many as 100,000 solid bricks. This daily production capacity means that when large local construction or municipal projects require urgent delivery, you can guarantee on-time fulfillment with just one machine—without worrying about penalties for late delivery.
- 21 MPa heavy-duty hydraulic system paired with 85 kN vibration force ensures high compressive strength of the bricks. The main unit’s hydraulic system pressure has been increased to 21 MPa, combined with 85 kN of table vibration force, with a vibration frequency adjustable between 2,800–5,100 r/min. This powerful physical compaction force thoroughly compacts cement, sand, and gravel in just over ten seconds. The resulting bricks feature high density and excellent edge hardness, and they consistently pass all random inspections.
- 51 kW high-power main unit supports high-intensity continuous operation. The main unit is equipped with a total power output of 51 kW. For large-scale commercial brick factories, it is critical that the machine does not overheat or shut down unexpectedly. The high-power motor, combined with a heavy-duty frame (overall dimensions: 8300 × 2800 × 2900 mm), ensures stable operation even during high-intensity, continuous production across two daily shifts, minimizing downtime for repairs.
- Siemens Smart PLC Control: Reducing Labor Costs Through Automation Equipped with a Siemens PLC and a smart touchscreen, the machine operates fully automatically. Although the machine is larger and output has doubled, automation allows the production site to operate with only 3 to 4 workers. Based on a single-shift output of over 14,000 hollow bricks, the labor cost per brick is reduced to an extremely low level.

Frequently Asked Questions about QT8-15 Automatic cement Block Machine
The QT8-15 block machine and QT6-15 look pretty similar, which one should I choose?
It really depends on your local market sales volume and order size. If your daily sales are within 10,000 units (8-inch hollow bricks), the QT6-15 block machine is more than sufficient. However, if you’re working on large construction sites, municipal projects, or planning to build one of the top-ranked large block plants in your area, we recommend going straight for the QT8-15 automatic cement block machine. It has a larger pallet (approximately 950 × 900 mm) and produces more bricks per mold (for example, 8 hollow bricks per mold), boosting daily production capacity to 15,000 bricks. For the same 8-hour workday, the QT8-15 block making machine can help you generate several thousand more bricks in profit.
What is the approximate budget and floor space required to set up a complete QT8-15 fully automated cement block production line?
When setting up a block manufacturing plant, you shouldn’t just look at the price of the main unit; you also need to consider equipment investment and site area:
QT8-15 Equipment Investment: Includes an automatic batching machine (PLD1600), a JS750 twin-shaft mixer, the QT8-15 main unit, and a fully automatic palletizer at the back end.
QT8-15 Space Requirements: The factory building (with a roof) should be no less than 350–500 square meters, primarily to house the production line and cement silos; an outdoor storage yard and finished product curing area of 3,000–5,000 square meters is recommended to allow for forklift maneuvering and stacking.
Is the strength of bricks produced by the QT8-15 sufficient?
The strength of bricks depends on the pressing force and vibration compaction. The QT8-15 cement block machine is equipped with a heavy-duty hydraulic power unit with a rated pressure of 21 MPa, combined with a high-frequency vibration system exceeding 85 kN. Provided the proportions are correct, the produced hollow bricks and load-bearing solid bricks fully comply with international standard brick specifications (e.g., MU10, MU15 and above).
The QT8-15 fully automatic cement block production line sounds very advanced. What if the workers don’t know how to operate it? Is daily maintenance a hassle?
Modern systems are highly intelligent, so there’s no need to worry. The QT8-15 control cabinet uses a Siemens smart touchscreen with a Chinese/English (and multilingual) operating interface; batching, pressing, and brick discharge are all automated with a single button press. We pre-configure the software before shipment, and during installation, our engineers will provide hands-on training to your on-site workers—typically, they’ll be proficient within 2–3 days. Routine maintenance mainly involves periodic grease lubrication, checking the hydraulic oil level, and cleaning mold residue. By following the maintenance manual, one person can easily handle it.
If I want to produce both hollow bricks and curbstones as well as grass pavers, is it difficult to change the molds?
Not at all. The QT8-15 cement block machine features a quick-change mold design. With the assistance of a crane, a skilled operator can complete a mold change in 1 to 2 hours. By equipping a single main unit with different molds, you can switch between producing hollow bricks, solid bricks, colored paving bricks, curbstones, and other products at any time in response to seasonal market changes, achieving “one machine, multiple uses.”
