Self-compacting concrete mobile batch station is suitable for high-speed railway CRTSIII type slab ballastless track special concrete which is a joint research and development of NFLG and the CHINA ACADEMY OF RAILWAY SCIENCES, specially developed and produced for China’s high-speed railway patent technology. The concrete for high-speed railway requires high fluidity, and can be cast flat without extrusion. This requires the mixer for cement production to have accurate measurement, very small deviations, and the ability to measure water content and temperature according to weather conditions. The NFLG self-compacting concrete mobile batch plant fully meets this demand.

Using replaceable friction disc type rubber roller, can be replaced within half an hour (Replacement of the old roller usually takes 4 days).Five cleanings + water cleaning to reduce belt abrasion.
Equipped with a 6.5m³ powder storage bin, which can be manually unpacked. There are arch-breaking mechanisms at multiple places in the silo to ensure smooth feeding. Accurate measurement of small and big connection to avoid the influence of screw conveyor on powder weighing, reasonable ventilation design, balance powder weighing air pressure, effectively prevent scale pulling and supporting.
Equipped with 1.5m³ water tank and 0.5m³ admixture tank. The specially designed liquid metering system is suitable special working conditions. Automatically realize the functions of over-weighing buckling and missing-weighing adding, timely adjustment, and improve the measurement accuracy.
There are two 1.2m³ stone storage bins and one 2.5m³ sand storage bin. The small belt dedicated for sand bins with frequency conversion is used to eliminate the difficulty of material blocking and improve the measurement accuracy.
The hydraulic lifting mechanism can store 2 batch materials, avoiding other defects such as the buckets design which needs to waiting material and improves production efficiency. The targeted enlarged discharge port can discharge the concrete quickly without residue.
Using pulse bag filter, the dust removal efficiency is as high as 99.9%, and low maintenance costs; The large fan actively extracts and removes dust, which can balance the pressure of each system in the main tower to ensure measurement accuracy and material discharge speed.
Based on the actual needs of customer projects, NFLG provides scientific production solution design to help enterprises achieve profitability.
