Description of ouble stage vacuum extruder

In brick and ceramic industry, this is the last machine which gives the final shape to the product. It basically consists of two main units. The first unit located on the top is a double shaft de-airing mixer. It mixes and kneads the clay material. Mud is then passed through a vacuum chamber in which de-airing of the material is achieved. The vacuumed mud is then directed towads the so called lower unit. Here the squeezing and driving augers carry the mud into the machine barrel. Finally the exrusion operation is completed by forcing the mud block through the desired die shape. This machine can handle materials with moisture ratios os 20 to 25 per cent. 
The double shaft de-airing mixer is a sturdy steel construction. The main body and other parts of the lower exruding machine are of heavy duty cast materials. 

At the outled port of the upper unit a cutter is installed. In this system the mud is brought to the most desirable condition for de-airing. Problems of over compaction and over loading in the vacuum chamber is thus prevented. 
All paddles and augers are made out of wear resistant steel. They are designed with high accuract to operate with minimum energy consumption. 

Slippage of mud in the forcing paddle section and in the machine barrel is prevented by easily replacable internal steel linings. 

Upper and lower units are driven by two different gear boxer and motors. Also clutching systems are installed on both units. 

Upper and lower units could be positioned atraight or at right angle with respect to each other depending on the plant layout requirementer

JKB40 hollow bricks making machine price

1.Description of  JKB40 hollow bricks making machine price

The primary extruder is without mixing system.This machine is also single stage structure which makes the whole set compact and reasonable.Mixing by machine saves time and effort.The raw materials agitation is relatively uniform which makes the end bricks color and quality of qualitative improvement.

Simple extruder with mixing box or not belongs to the first generation.The next stage came with the application of vacuum technology.A vacuum chamber is added before extruded portion.The operators can see the internal workings via the side observation room.This is a true stage of quality improvement.After vacuum stage,the intensity of the mud is much strengthened.Soft mud pieces need second setting but the bricks made by the vacuum extruder can burned directly after cutting.This is also a milestone of reducing the production cost.

New technology brick Hoffman kiln for firing clay brick

  A Hoffman kiln consists of a main fire passage surrounded on each side by several small rooms. Each room contains a pallet of bricks. In the main fire passage there is a fire wagon that holds a fire that burns continuously. Each room is fired for a specific time, until the bricks are vitrified properly, and thereafter the fire wagon is rolled to the next room to be fired.

Each room is connected to the next room by a passageway carrying hot gases from the fire. In this way, the hottest gases are directed into the room that is currently being fired. Then the gases pass into the adjacent room that is scheduled to be fired next. There the gases preheat the brick. As the gases pass through the kiln circuit, they gradually cool as they transfer heat to the brick as it is preheated and dried. This is essentially a counter-current heat exchanger, which makes for a very efficient use of heat and fuel.

  

The modern Hoffman kiln for clay brick has the following advantages:1.low investment,low influence to environment,high capacity.

2.We can put adobes or green bricks directly into the hoffman kiln

so that we do not need to invest on the tunnel kiln.
3.The brick production will not be influenced by weather condition any more.
