2. On-Site Production Operation

This project is a flagship large-scale intelligent brick production line built for super-large batch hollow block orders. Facing the huge material demand of urban commercial buildings, industrial parks and large residential supporting projects, the customer introduced the QT12-15 high-end full-automatic brick making production line. After precision installation, hydraulic parameter calibration and hollow block exclusive formula debugging, the equipment has achieved stable 24-hour uninterrupted cyclic production, becoming the core equipment to support the factory's large-volume supply capacity.

Different from medium-sized brick machines, the QT12-15 is equipped with an upgraded heavy-duty frame and high-efficiency platform vibration system, with a vibration frequency of 2800-4500r/min and adjustable frequency conversion. Matched with 21MPa stable hydraulic pressure, it realizes full and uniform filling of hollow block mold cavities. The molding cycle is stably controlled at 15-25 seconds, with extremely high single-cycle output. The hourly output of standard hollow blocks reaches 2700-2900 pieces, and the daily stable output exceeds 45,000 pieces, which far exceeds the production limit of conventional models.

The mass-produced hollow blocks have complete and regular hole structures, smooth and flat inner and outer walls, uniform overall density, and no defects such as hole deformation, wall thickness deviation and internal hollowing. The finished products have stable compressive strength and excellent thermal insulation and sound insulation performance, fully meeting national building wall standards. The production line supports diversified solid waste proportioning, which can make full use of local low-cost waste raw materials. While ensuring 100% qualified products, it effectively reduces comprehensive production costs and realizes high-efficiency green environmental protection production.

3. Unique Advantages of QT12-15 for Hollow Block Production

Flagship super-large output, solving large-order capacity pressure

As a high-capacity flagship model, QT12-15 has optimized mold layout and operating rhythm. It maintains efficient and stable cyclic operation for a long time, with industry-leading hourly and daily output. It perfectly solves the capacity bottleneck of large brick factories and fully meets the continuous and bulk supply demand of super-large construction projects.

Variable frequency vibration + constant pressure molding, ultra-stable hollow block quality

Equipped with 80-120KN adjustable high-power vibration system and 21MPa constant-pressure hydraulic device, the vibration force can be adjusted according to raw material ratio and brick type requirements. The material filling is uniform without dead corners, effectively avoiding common quality problems such as incomplete hole forming and loose brick body in hollow block mass production. The batch consistency of finished products is excellent, and the defective rate is extremely low.

Ultra-wide raw material adaptability, prominent green cost reduction effect

The equipment has low requirements for raw materials, and can flexibly utilize various industrial solid wastes such as fly ash, slag, tailings and construction recycled aggregate for batching production. Waste materials can partially replace cement and natural aggregates. The scientific proportioning formula does not affect the structural strength and thermal insulation performance of hollow blocks, maximizing resource utilization and production profits.

Intelligent integrated control, low labor and high efficiency

The whole line adopts PLC centralized intelligent control and frequency conversion energy-saving technology. Hollow block production parameters are one-key fixed and automatically operated. The equipment has fault self-diagnosis and early warning functions, which reduces manual intervention and operation errors, ensuring long-term stable and standardized production quality.

Heavy-duty reinforced structure, durable for long-term high-load operation

The whole machine adopts 12.6-ton heavy-duty integrated welded frame and thickened wear-resistant manganese steel mold, which is specially adapted to long-term high-frequency and high-load hollow block production scenarios. The core hydraulic and vibration components are of high quality, with strong fatigue resistance, stable operation and low daily maintenance cost.

4. Customer On-Site Evaluation

The customer purchased the QT12-15 full-automatic brick making production line, targeting the large-scale batch production of high-standard hollow blocks for large engineering projects. After long-term on-site operation and market verification, the customer highly recognized the equipment's super-high productivity and stable quality performance.

The equipment runs smoothly with low failure rate and explosive production capacity, completely meeting the long-term bulk order demand of local large-scale construction projects. The produced hollow blocks have neat appearance, standard size and stable thermal insulation and compression resistance, with a high project acceptance rate. The equipment makes full use of solid waste raw materials to reduce production costs, and the high intelligence level saves a lot of labor investment. The customer confirms that QT12-15 is the preferred flagship equipment for large and medium-sized brick factories to achieve high-efficiency and large-scale hollow block production.
