The complete production process for manufacturing clay bricks using the HR2-25 compressed soil block machine
Producing clay bricks with the HR2-25 compressed soil block machine involves mixing clay, cement, and water, followed by hydraulic pressing to form high-strength, high-density bricks; the entire production process comprises three stages: raw material preparation, pressing and molding, and post-production curing
The process begins with the preparation of raw clay: clay is excavated at the production site and then crushed and screened to produce fine, uniform particles. Next, the clay, cement, and water are loaded into a JQ350 mixer in the required proportions and mixed for 2–3 minutes until the materials are thoroughly blended and the mixture reaches the ideal moisture consistency—forming a clump when squeezed by hand but crumbling easily with a light touch.
The second stage is the production phase: workers pour the prepared clay raw material into the hopper of the HR2-25 compressed soil block machine and lightly press the control switch with their foot. The compressed soil block machine then automatically performs the operations of material feeding, hydraulic molding, and demolding. Workers move the demolded clay bricks to an open area and press the control switch again, repeating this cycle for continuous production.
The dual-version HR2-25 compressed soil block machine offers enhanced versatility, providing a “double guarantee” for clay brick production while optimizing operating costs and delivering superior long-term value. Where a stable power supply is available, the machine can be powered by an electric motor, ensuring low operating costs, silent operation, and zero exhaust emissions—making it ideal for long-term, large-scale production. Alternatively, in areas with unstable power or at remote, cold, and humid work sites, a diesel engine can be used; diesel engines feature mature technology and exceptional environmental adaptability, ensuring the HR2-25 compressed soil block machine continues to operate reliably even under harsh conditions.
The simplest and most direct method is a tactile test: “squeeze into a ball, crumble upon impact.” First, a worker takes a random handful of the raw clay material from the JQ350 mixer and squeezes it in their hand; upon release, the material holds its shape as a ball without crumbling or sticking to the hand. Next, the ball is dropped freely from a height of one meter; if it breaks apart into several pieces upon impact, the moisture content is deemed appropriate.
Before starting the diesel engine, first check the fuel and engine oil levels to ensure there is a sufficient supply, and perform a walk-around inspection to check for any oil leaks. Additionally, the engine oil and oil filter should be replaced every three months, while the diesel filter should be replaced every six months. After starting the engine, let it idle at low speed for 2–3 minutes before commencing clay brick production.
Before starting the HR2-25 compressed soil block machine, inspect the battery casing for cracks or leaks, ensure cable connections are secure, and check battery terminals for oxidation; any oxidation must be cleaned off promptly. Use a multimeter monthly to measure the static voltage; if the charge level falls below 50%, recharge the battery immediately to prevent plate sulfation, which can lead to a reduction in battery capacity. Additionally, keep the exterior of the battery clean by gently wiping the surface with a cloth or sponge.
The difference between diesel and electric power modes lies not in output capacity, but in how well they suit the customer’s on-site operating conditions; both modes ensure continuous production across diverse settings—whether in areas with stable power supplies, remote locations lacking electricity, or regions with harsh environmental conditions. Data confirms that the baseline output remains consistent regardless of whether the diesel or electric mode is used.
During the production of clay bricks with the HR2-25 compressed earth block machine plans pdf, a light tap on the foot pedal immediately triggers a complete single pressing cycle. This frees up the operator’s hands, allowing them to initiate the cycle while handling the bricks; furthermore, the foot pedal’s design prioritizes safety, preventing accidental activation—and the resulting hazards—during the handling process.
