We are a professional exporter of mini concrete batching plant. This is a new type concrete batching plant which is much smaller size concrete batch plant. Besides due to its small body the whole plant covers small space which can reduce users’ cost. As one of mini cement plant manufacturers our target is to supply high-quality mini cement plant project to clients all around the world.
1. Mini concrete batching plant is similar with other concrete mixing plant. It is also a combination of batching station belt conveyor silo screw conveyor concrete mixer weighing system water and air supply system control system and so on.
2. This plant is suitable for small and medium-sized construction sites. And the machine can mix kinds of concrete and mortar.
1.Horizontal twin-shaft compulsory mixer has strong mixing ability it can mix the materials evenly and effectively. It can mix concrete with different slumps and raw materials ratio. Its mixing blade and lining board are made of high chromium wear-resistant alloy. External shaft end support and special shaft seal ensure the long sevice life of the mixer.
The quantity of aggregate silos depends on the customer’s requirements usually three silos. A wheel loader can be used to transferthe aggregates to the aggregate silos. In the bottom of the aggregate silo there are one fine aggregate and one coarse aggregate discharging gate. Once receiving signals the cylinder will open the discharging gate and the aggregates are discharged into the weighing hopper respectively.
It adopts special DSB-III it has the function of automatic difference compenstaion. aggregates cement water and additive all has their own weighing machine and the results are accurate.
Aggregate transfering system
After weighing the aggregate are sent to the hopper from the hopper the aggregates are dicharged into the mixer.
The whole plant is controlled by industrial control computer. This system has the following features:real-time data processing function; both automatic and manual control are available; simple and convenient operation. It can save all the data of the plant and the materials ratio; It can also print all the report forms. Constant temperature containerized type of control room adopts sound and heat insulation colorful battenboard which can ensure the working temperature of electrical devices and also provide a comfortable enviroment for the operator.
1. It is PC+PLC control which can vividly display the production process on the screen so that the operator can monitor whole process all the time.
2. Scale board and mixing blades are made of wear resistant alloy special shaft end seal and longer service life.
3. Screw conveyor is a new type of transporting equipment which use rotary screw vane to push material continuously in closed housing with round section.
4. The silo can be used to store cement coal ash and other kinds of powder as a main part of concrete batching plant.
Installation site should be plain and well-grounded. The pithead should be higher than ground to prevent the water inflow.
Lift the mixer with lifting device and install four supporting legs connecting angle inclined strut ladder and the downward track. Then place the mixer in the appropriate place of the pit.
2. Inspection and preparation before test
Check if the connection of the motor and electric element is steady.
Check connecting bolts between two parts(especially the moving parts) and ensure they are firm. If not tight them up in time.
Check if there are sundries stuck in mixing canister and track rack.
3. No-load test
Start mixing motor. At the same time the running direction of two mixing shafts should be same with indicating direction of the signs . If there is any difference change the power connection.
4. Over-load test
Shut down the discharge door and lift the hopper after feeding. Insure that the hopper can run steadily and stop on the track freely. If there is slipping you should put the hopper into the pit bottom then adjust the big nut in brake motor.
1. Focus on the maintenance of quick-wear parts and reserve appropriate spare parts.
2. When the machine is on maintenance adjustment or cleaning cut off the total power switch and hang a warning sign.
3. Contact with local power supply departments and require them to supply reliable electric power .
4. There must be an experienced electrician who is responsible for the daily maintenance of electrical equipment specially.
5. If the plant installed is taller than the surrounding buildings or equipment the lightning protection facilities should be collocated.
6. All the safety signs shall be inspected at least once every six months. If there is any damage deformation color fading etc. the signs should be repaired or replaced in time.
