The composition of the mobile mini concrete batching plant is relatively simple compared to the large-scale commercial concrete mixing station. The gas path system of the mini mobile concrete batching plant is composed of an air compressor, a cylinder, a solenoid valve, a water separator, an oil mister and a pipeline. The air source is supplied by the air compressor, and enters each branch through a pressure reducing valve, a water separator and an oil mister, and a gas distribution package.

The supporting gas path includes the batching system supporting gas path, the cantilever pulling shovel system supporting gas path, the stirring system supporting gas path, the cement silo supporting gas path, the admixture, the water, the cement, and the fly ash metering supporting gas path.
The batching system supporting gas path of mobile concrete batching plant is composed of an integrated solenoid valve and six cylinders, control the opening and closing of the four batching doors through the cylinder to complete the batching process.
The cantilever shovel system supports gas path is consist of two cone clutch cylinders in the hoist, two outer brake cylinders and corresponding manual and foot valves. The shovel driver controls the electromagnetic valve to realize the bucket throwing and collecting.
The stirring system branch circuit is composed of two series cylinders and one electromagnetic gas valve. The two cylinders push and pull open and close the concrete discharge door.
The cement silo supporting gas path is composed of electromagnetic valve and the oil-water separator. When the cement in the cement silo is arched, the electromagnetic valve breaks the arch according to the manual instruction or the automatic command issued by the microcomputer.
Admixture, water, cement, fly ash metering gas route of mobile mini concrete batching plant is composed ofan integrated solenoid valve, control each cylinder to complete the metering and delivery of admixture, water, cement, fly ash.
