Applicable Raw Materials: Sand, stone powder, crushed stone, cement, fly ash, slag, mine waste and construction recycled aggregate

Complete Line Configuration: JS750 forced mixing system, automatic batching unit, quantitative feeding conveyor, QT8-15 forming host, 21MPa high-pressure hydraulic station, frequency conversion vibration system, PLC intelligent control system, automatic pallet feeding and brick output device

On-Site Operational Status

This project is a large-scale standardized intelligent brick production line tailored for high-volume hollow block batch production. After professional assembly, precision commissioning and hollow block formula optimization, the QT8-15 production line has been put into 24-hour continuous stable operation, supplying high-standard hollow blocks for large residential communities, commercial buildings, industrial park construction and urban infrastructure projects.

Upgraded from conventional medium-sized brick machines, the QT8-15 features enhanced platform vibration and high-pressure hydraulic synchronous molding system. With a vibration frequency of 2800-4500r/min and maximum exciting force up to 90KN, the equipment delivers uniform filling and dense compaction for hollow block blanks. The stable molding cycle is controlled at 15-20 seconds, with 8 standard hollow blocks molded per pallet, achieving a daily output of over 15,000 qualified hollow blocks, which far exceeds the production capacity of ordinary QT6 series equipment.

The finished hollow blocks present complete and regular hole structures, smooth inner and outer wall surfaces, uniform overall density and stable compressive strength. There are no common defects such as hole deformation, wall thickness deviation and internal hollowing. The production line supports diversified raw material proportioning, which can fully utilize local low-cost aggregates and industrial solid wastes. While ensuring 100% qualified hollow block products, it effectively reduces comprehensive production costs and realizes green and efficient production.

Unique Advantages of QT8-15 for Hollow Block Production

1. Industry-leading large output, meeting super-large order demands

As an upgraded high-efficiency model, QT8-15 has significantly improved single-mold output and hourly capacity compared with ordinary brick machines. The stable cyclic operation supports long-term uninterrupted mass production, perfectly solving the capacity bottleneck of medium and large brick factories, and fully meeting the continuous supply requirements of large-scale construction projects.

2. High-frequency variable vibration, superior hollow block molding quality

Equipped with frequency conversion adjustable vibration system and 21MPa stable high-pressure hydraulic device, the equipment realizes three-dimensional uniform compaction of brick blanks. It effectively avoids hollow block quality problems such as incomplete hole forming, loose structure and uneven hardness caused by insufficient vibration force. The batch product consistency is excellent, and the defective rate is extremely low.

3. Ultra-wide raw material adaptability, prominent cost-saving effect

It is compatible with various low-cost raw materials such as stone powder, fly ash, slag and construction recycled aggregate. Various industrial waste residues can be scientifically proportioned to replace part of cement and natural aggregates. The flexible formula does not affect the structural stability and load-bearing performance of hollow blocks, maximizing the economic benefits of brick factories.

4. Intelligent integrated control, low operation difficulty

The whole line adopts PLC centralized intelligent control, with one-key fixed parameter production and automatic cycle operation. The equipment has built-in fault self-diagnosis and early warning functions, which reduces manual intervention and operation errors, ensuring long-term stable and consistent product quality.

5. Heavy-duty reinforced structure, durable for long-term operation

The whole machine adopts thickened heavy-duty frame and high-strength wear-resistant molds, which is specially optimized for high-frequency and high-load hollow block mass production scenarios. The core hydraulic and vibration components are reliable, with strong fatigue resistance, low failure rate and simple daily maintenance, greatly reducing later operation costs.

4. Practical Customer Evaluation

The customer purchased the QT8-15 fully automatic brick making machine specially for large-batch and high-efficiency production of construction hollow blocks. After long-term on-site operation and market verification, the customer highly recognized the equipment’s comprehensive performance.

The equipment runs stably with low failure rate and sufficient explosive production capacity, fully meeting the large-volume order demand of local construction projects. The produced hollow blocks have neat appearance, standard size and stable strength, which pass engineering inspection with a high rate. The equipment makes full use of waste raw materials to reduce production costs, and the high degree of automation saves labor investment. The customer confirms that QT8-15 is an ideal high-efficiency production equipment for large-scale hollow block factories.
