How Can the Water in a Block Factory Avoid "Flowing Away for Nothing"?
In the cost accounting of a block production line, water charges often account for only a very small proportion. Many factory managers believe that what goes into the water is nothing more than tap water and curing steam, which costs little. But in fact, from the invisible water carried in by aggregates, to the precise water for batching and mixing, and to the wastewater from cleaning equipment and pallets, an improperly managed production line loses not only water resources every year, but also cement and aggregates hidden in the wastewater and waste slurry.
In the design of its complete-line solutions, UNIK Machinery treats "water supply, water use, and waste slurry recycling" as a closed loop of a systematic project, allowing every drop of water to deliver its proper value.
1. Precise Water Addition: No More "Going by Feel"-Relying on Precision Flow Meters
In traditional small block plants, adding water to the mixer often relies on the operator "judging by the look of the mix"-manually opening the valve and closing it when it looks about right. This rough-and-ready approach directly causes fluctuations in the water-cement ratio and seriously affects block strength.
In the JS series forced mixers supplied by UNIK, the water supply system is precisely controlled by a central PLC. The system is equipped with a high-precision water flow meter. Once the water addition amount is set, the PLC not only controls the start and stop of the water pump, but can also automatically close the valve based on the real-time data fed back by the flow meter. The JS series mixers are equipped with dedicated pump motors ranging from 0.75 kW to 7.5 kW, ensuring that even with large-capacity models (such as the JS2000), a strong and precise water supply can be delivered in a short time.
2. Aggregate Moisture Compensation: Making "Invisible Water" Visible
The moisture carried in sand and gravel aggregates is the culprit that disrupts the water-cement ratio of the mix design. High-end production lines must be equipped with online moisture meters. Before the aggregate enters the batching station for weighing, the system measures the moisture content in real time and automatically deducts the weight of "water" in that batch of aggregate in the PLC program, while simultaneously reducing the water addition amount of the mixer. This closed-loop compensation mechanism keeps the actual water-cement ratio of each batch of concrete locked in the optimal range, which not only saves cement (because excessive water requires more cement to maintain strength) but also avoids mold sticking and rejects caused by excessive moisture.
3. Waste Slurry Recycling: Turning Cleaning Water into a "Resource"
The forming machine and mixer need to be cleaned after shutdown every day, and the pallet return line also generates a large amount of flushing wastewater. If this waste slurry water is discharged directly into the sewer, it not only risks environmental penalties but also represents an enormous waste of resources.
In its complete-line design, UNIK can integrate a waste slurry mixing and recycling system. The waste slurry water generated by cleaning equipment flows into a waste slurry tank equipped with a mixing device to prevent cement from settling and hardening. Subsequently, through a sewage pump, it is recycled in proportion into the water supply pipeline of the mixer and used directly as mixing water for the next batch of concrete. This not only solves the discharge problem but also reuses the cement particles in the wastewater, achieving "zero discharge" green production.
From the moisture carried by a single grain of aggregate to a tank of seemingly useless cleaning waste slurry, UNIK minimizes the loss and waste of water resources through the intelligent control and recycling design of the complete-line system, helping customers squeeze out every bit of hidden profit while remaining environmentally compliant.
