HSR Concrete Mixing Plant

Home / Product / Ready-mixed Concrete Mixing Plant /HSR Concrete Mixing Plant

The high-speed railway concrete mixing plant developed by NFLG perfectly meets the requirements of high-speed railway construction, ensuring the accuracy of calculation and measurement as well as proportioning, the homogeneity of mixing and meeting the standards of aggregate arrangements. Based on its 25 years of experience on mixing, NFLG has developed 10 categories of concrete mixing plants with 35 models. The big concrete mixing stations with the volume above four cubic meters take the biggest share of market.

01

Aggregate Weighing and Conveying System
Individual aggregate weighing system.
Groove belt conveyor takes a small floor space with high efficiency.
The original return belt conveyor can totally solve the blanking problem of groove-belt conveyor.
Sand hopper exclusively uses the structure of "liner-board with vibration", not only able to make the sand down by vibration, but also will not cause the board to be shattered, significantly solving the problems of aggregate measurement inaccuracy due that sand material distribution is uneven and not smooth.

02

Compact Structures
It is easy to move with its compact structure.

03

Powder Weighing System
The accurate feeder screw conveyor can be used in the weighing of powder. Both screw conveyors can work simultaneously. When the feed amount is nearly target, the main screw conveyor will stop working and the small screw conveyor will continue working, achieving the goal of accurate feeding.
Screw conveyor outlet with butterfly valve can avoid the inaccuracy of weighing led by unstable blanking for inertial.
Each powder can be calculated and measured independently, which is convenient to add and remove, ensuring the accuracy of weighing.
The big end and small end joining technique is used between powder scale and screw conveyor and mixer without powder accumulation and impacts on the measurement.
The connection between powder scale and platform is non-welding and unlocking, avoiding the inaccuracy of weighing of powder made by calculation and measurement platform deformation when overfeed.
Reasonable permeability design and balance powder scale pressure effectively avoid impacts on the measurement.

04

Liquid Weighing System(Engineering Liquid Supply System)
Rough and precise calculation of liquid admixture as well as adjustment equipment such as stock bag and manual ball valve can adjust at proper time and rise the accuracy of weighing.
Upstairs water storage tank can automatically drop by gravity. Flux is more stable. Weighing is precise. Rough and precise measurement, and automatically add the lost and remove the extra, and ensure measurement accuracy.
Independent admixture scale, adding in advance and adding later are both feasible. Admixture leakage prevention device can ensure the quality and safety of the concrete.
Small-amount of admixture weighing system is available, which is designed for small-amount liquid admixture such as air-entraining agent. The smallest add amount reaches 0.4kg/cube when under the national standard error.

05

Mixing System
The JS/SUN mixer can be applied to all kind of production process.
Twin-spiral mixer can save 15% of the mixing time and 20% of the energy.
The most smooth mixer in China (Clean 1 time once a month).
Gate-type discharge hopper and the discharge hopper speed are controllable without spatter and draining.
