مشروع مكنه لصناعه الطوب الاسمنتى

Dear PLCMAN,
Actually i was trying to give hand in this subject but as i have explained earlier that such plants are tailored according to the clients requirements, this is why i have asked the to upload all required information, anyways i will try to explain in simple manner how such machine works and i will upload some drawings and circuit diagrams ,and part of the program hoping that will make things more clear .
Actually as i have seen in the pics earlier uploaded this is a semi automatic plant the automatic part is related to the block making machine
.
normally the manufacturing process is summerised as below
1-Dosing of raw material that comprises of crushed washed sand 4.5mm, 3/8inch aggregate,plaster sand 2.5mm
2-there are several types of dosing either through conveyor belt below the hoppers where the raw material is stocked and this conveyor is driven by electric motor with gear box and there is an opining of XxY opened to the raw material directly by knowing the speed of conveyor belt and the opening through which the material is passes from the hopper VxXY you can know the volumetric flow of the material you can adjust the time to dosethe required material and this small conveyor belt throw the material to a bigger conveyor belt where material is transfered to the concrete mixer .
the other type is by having a pneumatic cylinder that is connected to the lower part of the hopper and it doses material by opening the hopper gate by the pnumatic cylinder to a transfer car that is held on 4load cells that weighs the material required from the hopper and it transfers to the 2nd ,3rd,4th hoppers that it doses the required weight of each material
2-The car will move after that to another car that transfer the material vertically to the mixer where material is mixed and cement will be loaded and starts the process of water addition and by having a probe fixed at the bottom of the mixer it measures the moisture in the mix and once the neede value is raeched water will stop and then the mixer will mix thw material for another15-20secs and then is transfered to the machine either by aconveyor belt below the mixer or by atransfer car
tomorrow i will upload some photos for understanding and we will continue ta;king about thae machine

الف شكر على هذه الاستجابه السريعه
ولكن لو سمحت تفصيل اكثر
ولو عملت البرنامج يكون افضل
