Clay and Coal Material Prepare and Treatment
By the Bulldozer or Loader to send the raw clay to the box feeder, the box feeder adopted the valve
controller, it can control the feeding quantity according to the requirements. Then, the raw clay through
the belt conveyor go to double-roll crusher for crushing.
Coal will be crushed by the coal crusher and being piled up. Then by labor vehicle or loading machine
send the coal to coal feeder, which adopt valve controller, can control the coal feeding quantity according
to requirement. Through the belt conveyor, coal powder will go to normal rolling crusher, together with
the clay crushing, coal powder and clay will be mixing completely.
The clay will receive second time mixing by fine pulverizing double roll grinder, in order to get the proper
grain size. By water adding again and mix, extrude, cut up, so that to get a better molding quality.
Molding
Extruding machine is the key equipment among the whole production line, its performance are required
as follows:
1) They can meet the need of different specification and hole shapes of the brick;
2) The vacuum degree is -0.092Mpa, the extruding pressure is 2.5-3.0Mpa;
3) The hourly output per set is more than 7000pcs bricks.
Moisture content when molding is controlled to 15%-18%.
Cutting and stacking
The columns will be cut into the required adobes by cutter, then the green brick be pulled distance by the
distributing machine and stacked onto the drying car by labor. The drying cars are transported by labor
to hydraulic ferry pusher at the inter end of drying chamber and be sent into the drying chamber.
The green wet brick will become to the requested semi-finished products after adding heat.
The dried car be sent into the hoffman kiln by the trailer what be pulled by the small tractor, stacking
the brick into the hoffman kiln by labor.
The brick bodies go through the pre-heat, firing and cooling, then be sent to the storage yard by labor.
Drying
In order to save energy, reduce the CO2and SO2 emission and take full use of the heat, green bricks are
dried by the tunnel drying chamber with small size cross section. Heat resource comes from the remaining
heat of the hoffman kiln.
Green bricks come from the cutter then being put on the drying cart by man after bricks distributing and
transferring machine, and then it will be sent to the drying chamber by the ferry pusher.
Firing
Dried bricks via the hydraulic ferry pusher are sent to the trail car. Then, the workers push the drying car
onto the trail car, then send to the Hoffman kiln / tunnel kiln for unloading, stacking and firing.
