DZK 烧结砖制砖机

DZK series single stage vacuum clay brick making machine has almost same structure as non-vacuum extuder, the different part is the former machine has a longer mud cylinder, the middle part of cylinder is separated into two parts which is composed of vacuum chamber.When the soil is pushed forward by auger and passes the grid,thesoil is splited into several thin mud column ,thus giving chance to exit air from soil.The vacuum chamber is settled with exhaust pipe.when soil passes vacuum room, the vacuum pump can exhaustair.

Advantages:

The structure is simple, low price, lower electricity consumption .It can produce solid ,multi-hole and hollow bricks.Cost-effective. If buyer does not have high demand on brick vacuum pressure, it is the best machine.

Disadvantages:

Residence time of Pug in vacuum chamber is short,  suction is uneven .vacuum degree is not high. And it has higher demand for raw materials, if mud compounds with stone, plant roots and other debris, the production process may cause blockage of the vacuum chamber, then need to clean up vacuum room,influencing production.

1.If the soil contains stone, such soil can be used to make bricks?

No,the stone must be removed, otherwise the machine will accelerate wear and tear, or even damage to the machine. Generally based on the size of stone, you can choose the following machines: stone removing roller machine, roller sieve, thrust sieve.

2.What fuel can be used for sintering the clay brick?

Coal, gas, oil, rice husk, coffee shell, wood and so on.

3.What's the difference between Single stage vacuum extruder and Double stage Vacuum extruder?

1).Double stage Vacuum brick extruder can make three kinds of brick, solid brick, porous brick and hollow  bricks.To produce different kinds of bricks, usually, only need to fix different brick die. It is composed of  upper stage mixing parts and lower stage extruding parts;

2).Single stage vacuum extruder usually can produce solid bricks. It has only lower stage extruding parts;

3).Double stage vacuum extruder has higher capaicty ,higher vacuum pressure than single stage vacuum extruder . Also double stage extruder green bricks contains less moisture.

4.What's the difference between Vacuum extruder and non-vacuum extruder?
1).Vacuum brick extruder can make three kinds of brick:solid brick, porous brick and hollow bricks.To produce different kinds of bricks by changing the different brick die.
2).Another type is the common clay brick machine, non vacuum brick extruder,can only produce solid bricks. Vacuum brick is extruded out of the vacuum extruder. And non-vacuum extruder has no extraction equipment,so the brick hardness is lower than vacuum brick.
3).The vacuum brick machine is first extracted with air and water and then fired,the production time and firing time is shorter, rapid prototyping.Greatly reducing the production cycle time.
