Technology description of D15 - G9 concrete block production
(1) Silo: A Special purpose storage contains cement. Besides the steady steel structure, it includes dust filtering system, anti-clogging aeration and safety valve.
(2) Batching machine: Include two or three materials hoppers. After feeding materials fully into hopper, they will be scaled exactly before transfering into machine
(3) Belt conveyor: Transfer materials after scaling to mixer
(4) Screw conveyor: Transfer cement and fly-ash from silo to cement scale
(5) Cement scale: Include a bucket and a scale. Scaled data will be displayed on control center to help workers monitor the production process easily
(6) Mixer: Aggregates (grind stone, sand, thermal slag, ect), water and cement after scaling are mixed together evenly as the setting parameter.
(7) Belt conveyor: Transfer materials after mixing to material deviding machine
(8) Material deviding machine: Store and deliver materials after mixing to block making machine
(9) Pallet feeder: Put pallet into block making machine to bear products and push them to block conveyor
(10) Block making machine: Being designed integratively between pressure, vibration pressure and forced vibration pressure. It creates a strong pressed vibration force to form blocks with high quality and uniformity.
(11) Block conveyor: Clean the surface and transfer block pallet to block stacker
(12) Cooling machine: Cool the hydraulic oil by circulating water pump system
(13) Color feeding machine: Receive the surface material mixture of interlocking block, paver block, ect, then feed color into the mould of block making machine
(14) Belt conveyor: Transfer surface material mixture after mixing to color feeding machine
(15) Pigment mixer: Mix the materials such as cement, sand, color matter, water, ect together to make a surface materials mixture for interlocking block, paver block, ect.
(16) Silo: a special purpose storage contains cement to use for mixing surface color
(17) Batching machine: Include two material hoppers to feed for area of mixing surface color
(18) Belt conveyor: Transfer material after scaling to pigment mixer
(19) Srew conveyor: Being mouted at the bottom of silo at the surface color mixing area.
(20) Cement scale: Include bucket and scale
(21) Elevator (10 storeys and 20 trays): Receive the wet block pallet from block conveyor and stack into 10 storeys
(22) Finger cart (10 storeys and 20 trays): Receive the wet block pallet from block stacker, then transfer to curing chamber, after that, receive the dry block pallet and feed for block stacking system
(23) Movement rails system: A rails system supports block conveyor transfer to the positions such as block stacker, lowerator and curing chamber
(24) Lowerator (10 storeys and 20 trays): Receive the dry block pallet from finger cart (10 storeys and 20 trays) and lower each pallet into block conveyor
(25) Cured block conveyor: Receicve block pallet from lowerator (10 storeys and 20 trays), transfer pallet with block to horizontal block conveyor and pallet without block to pallet turner.
(26) Horizontal block conveyor: Separate and transfer block from cured block conveyor to block conveyor and turned machine.
(27) Block conveyor and turned machine: Gather and turn block horizontally and transfer to pending position for stacking.
(28) Cuber: Pick the block up from the pending position to stack into bale (block bale)
(29) Chain type conveyor: Transfer block bale to pending position for wrappong nylon
(30) Pallet turner: Turn and clean pallet
(31) Pallet gathering machine: Receive pallet from chain type conveyor, then gather at the beginning position.
(32) Nylon wrapping machine: After wrapping nylon, the block bales will be transferred by forklift to the finished product yard.
(33) Curing chamber: Contain block bale for natural cure within 24 hours
(34) Control center: Contain electric cabinet and operating worker
Production process of D15 – G9 concrete block
(B1) Step 1: The dumper feeds materials (stone, sand, ash, slag, ect) into hoppers to scale.
(B2) Step 2: The materials after scaling are mixed together with cement and water.
(B3) Step 3: The pressure - vibration machine forms block piece as the mould. In this process, workers must regularly check to adjust timely to limit the error products.
(B4) Step 4: The dumper feeds materials (sand, ect) into hoppers to scale
(B5) Step 5: Mix the materials such as cement, sand, color matter, water, ect together to create the mixture of surface materials for interlocking block, paver block, ect
(B6) Step 6: The materials for surface are discharged to belt conveyor and transfered to pigment feeding machine. Color is fed in the surface of block, then block making machine vibrates and presses the second time
(B7) Step 7: Atfer forming, block stacker rucks block into 10 storeys.
(B8) Step 8: Finger cart transfers blocks to curing chamber from 18 to 24 hours, then transfers to lowerator and stacks into bale.
(B9) Step 9: Lowerator (10 storey and 20 trays) separates each pallet to cured block conveyor
(B10) Step 10: The machine pushes the pallet with block to horizontal block conveyor and pushes the pallet without block to pallet turner at once
(B11) Step 11: The machine gathers and turns block then transfer to stacking pending conveyor
(B12) Step 12: The cuber picks block up from stacking pending position to stack into bale
(B13) Step 13: After stacking, block bale is wrapped by nylon and transferred to finished product yard. After from 15 to 20 days, block can be exported.
