The mobile concrete mixing plant is a concrete production equipment which integrates the material storage, weighing, conveying, mixing, discharging and fully automatic control system of concrete mixing plant into one trailer unit; it is identical to the fixed automatic mixing plant in terms of operation, operation and maintenance, It is the best model for mobile construction of public railway, bridge, port, hydropower and other projects.
Mobile concrete mixing plant model letter meaning: YHZS: Y – mobile, H – concrete, Z – mixing plant, S – using double horizontal shaft mainframe; so its official name is "mobile concrete mixing plant". Abbreviated as "Mobile Mixing Plant.
2. Main Features
At present, there are two types of mobile concrete mixing plants: tractor type and trailer type. The tractor type chassis contains a complete front and rear axle; the trailer type chassis only has a rear axle, and the front end is placed on the saddle axle of the tractor.
Quick disassembly and assembly, easy to move
When transferring: Except for the screw conveyor and cement silo, the whole mixing plant can be hauled and moved by dropping the front end; others such as the walking platform and the raised plate are folded down, and all the control cables need not be dismantled. The dismantled accessories can be taken away with the plant.
The mobile concrete mixing plant is equipped with tires, traction pins, signaling device and braking system, and the maximum speed allowed when the trailer is towed is up to 50 km/h.
For installation, a flat and hardened surface is required; for disassembly, a 30-ton crane is required.
When storing: If the equipment is not used temporarily, keep the transportation status when transferring.
Other performance, operation method and principle are the same as that of fixed standard mixing plant.
All parts of the mobile concrete mixing plant are smaller than the inner container size, and three 40-foot containers are required for the transport of the whole plant.

Main machine chassis: cantilever-shaped mixing machine chassis, which contains towing pins and parking legs of the truck; the chassis is equipped with the mixing machine, cement and water admixture weighing scale; the surrounding inspection platform and railing are attached.
Control room: The control room is located at the bottom of the chassis of the main machine and contains the fully automatic control system of the mixing plant. The control system is the same as that of the fixed mixing plant; the control room is used as the front support point of the whole plant when it is in working condition; the control room is put away in the inner space of the support when it is transferred; all the control lines do not need to be dismantled.
Aggregate batching and metering: This system is located at the back end of the whole plant, the upper part is the aggregate (sand and stone) storage hopper, which can be divided into 2 or 4 compartments and equipped with a heightened plate to increase the storage capacity, and the door is opened in pneumatic order. The bottom part is equipped with walking rear axle and working frame legs.
Belt conveyor frame: The frame is a truss structure connecting the chassis of the main machine and the aggregate batching frame, and the belt frame is installed inside; so that the main machine frame, belt frame and batching frame are integrated to form the main structure of the whole mobile mixing plant.
Peripheral parts: cement silo and screw conveyor. The peripheral parts are integral parts no matter working or transporting, so they can be transported and disassembled as a whole.
Mixing machine: Generally, it adopts JS type forced mixer, which can mix liquid and dry concrete quickly and evenly.
