The Mini Batch Concrete Mix Plant

The mixing drum of the mini batch concrete mix plant mixer is equipped with two horizontal mixing shafts. Each shaft is equipped with mixing blades. The blades of the double-shaft concrete mixer of mini concrete mixing plant are staggered. The mixing arms of the same serial number on the two shafts reach the same position in the mixing area. The phase difference is 135°, the connection between the stirring arm and the shaft is split bolt connection (during the mixing process, if the stirring arm breaks, it can be quickly replaced), and the stirring arms near the two ends of the mixing drum are equipped with side blades, which can be scraped off. The concrete on the end face changes the flow direction of the concrete, and the gap between the blade and the village slab is less than 5mm.


 
Due to the discharge capacity of the concrete mixer is relatively large capacity, generally use the bottom opening door type, which can not only make the concrete be discharged smoothly during the mixing process, but also avoid the cylinder tipping, which is safe and labor-saving, shows a lot of freedom and is easy to operate. The unloading mechanism of mini batch concrete mix plant is controlled by a hydraulic system, which can reduce the labor intensity of workers and improve the safety of equipment. In the case of an emergency when the hydraulic system fails, the machine is equipped with a safety device, and workers can manually operate the safety handle to open the discharge door.
 
The storage hopper of the mini concrete batch plant is composed of hoppers with equal volumes. The box can be disassembled and assembled for transportation. The aggregates in the storage hoppers are loaded by a loader. Each hopper has a volume of 10m3. The bucket doors in the frame are controlled by air cylinders, and feed materials into the sand weighing bucket (each two bucket doors control one aggregate).
 
The overhaul of the mini batch concrete mix plant is for the purpose of restoring the original performance of the machine. The interval is 100,000min, and the maintenance is stopped for one week. The operator will carry out an extra repair shift, including the middle repair content and add: replace all the liner mixing blades and part of the mixing arm; replace the belt chain Coupling rubber block; replace the lubricating oil in each turbine gear box, replace the lubricating oil in the turbine gear box, replace the air pump (pay attention to the difference in winter and summer); clean and check the main shaft bearing to determine whether to replace it.
