Operation

The QTS4-10 features a robust, all-welded structure made from thickened, national-standard steel plate. The machine body offers high rigidity and pressure resistance, resisting deformation and enabling stable, continuous 24-hour operation. It is equipped with a high-flow hydraulic system capable of a rated high pressure of 31 MPa, ensuring uniform pressing force. With four molds forming simultaneously, the density, thickness, and uniformity of the four bricks are identical, effectively preventing defects such as size inconsistencies, voids, or loose structures.

The equipment is controlled by an intelligent PLC system that enables one-touch automated operation, handling the entire process—feeding, vibration, pressure holding, and demolding—automatically. With short molding cycles and precise movements, labor requirements are minimal, limited to monitoring the machine and transporting finished products. The molds are constructed from high-hardness alloy materials, offering excellent wear and pressure resistance as well as a long service life; they support quick disassembly and replacement, allowing for easy switching between different brick types. The equipment features adjustable pressure, height, and vibration frequency settings. Parameters can be intelligently adjusted based on local soil moisture levels, clay-to-sand ratios, and cement mix proportions to accommodate the specific raw material characteristics of different regions.

The machine boasts a mature structural design, a low failure rate, and a high degree of parts standardization, making it easy to source replacement parts overseas. An optional diesel power system allows for operation independent of the industrial power grid, ensuring stable production at remote construction sites, mining areas, and large-scale rural projects.

Working Principle

The QTS4-10 utilizes a molding process combining high-pressure hydraulic extrusion with vibration-induced compaction. First, clay, cement, and water are mixed thoroughly according to a scientifically determined ratio; the mixture is screened to remove stones and impurities, resulting in a fine, uniform raw material. This mixture is fed via an automated conveyor system into the main machine’s hopper, where it automatically and evenly fills four mold cavities. The equipment then initiates high-frequency vibration to ensure the material fully fills the cavities and to expel trapped air. Subsequently, the hydraulic system rapidly descends to apply and maintain high pressure, bonding the soil particles and cement to simultaneously press four high-density solid brick units. Once the molding and pressure-holding phase is complete, the upper mold retracts, the mold frame lowers to release the bricks, and the finished bricks are gently deposited onto the ground.

The bricks require no firing; they harden through the natural hydration of the cement. After 7–14 days of open-air curing, they achieve the standard strength required for construction, slope protection, and paving applications. The entire process is pollution-free, produces zero smoke emissions, and consumes minimal energy.

Configuration

1. Clay Crusher: Breaks down large, compacted clay clumps and refines the soil texture to ensure uniform mixing.

2. Vibrating Screen: Filters out stones, roots, and hard lumps to protect the molds and increase the yield of high-quality finished bricks.

3. Forced-Action Mixer: Thoroughly blends soil, cement, and water, ensuring a consistent mix ratio and uniform moisture content.

4. Belt Conveyor: Provides fully automated material feeding, eliminating the need for manual loading. 5. QTS4-10 Fully Automatic Molding Unit: Features synchronous pressing across four molds; serves as the core molding equipment.

6. Independent High-Pressure Hydraulic Station: Supplies stable pressing power and ensures balanced pressure across all four molds.

7. PLC Intelligent Control Cabinet: Manages automated operation, parameter adjustments, and fault alerts for the entire system.

The entire production line features a high level of automation, requiring only 2–3 operators to manage production; it is ideal for long-term, large-scale brick manufacturing.
