The investment of Tunnel kiln and tunnel dryer about 60~70% of whole project, we have professional team for kiln construction and supervision, most of the brick project facing problem from kiln and dryer. But we are professional in dryer and kiln.
A tunnel kiln is a type of continuous kiln that is typically open on both ends and heated centrally. Building materials, such as bricks, may be passed through the device in an uninterrupted fashion, allowing large volumes to be processed without shutting off the kiln between batches.

A number of different methods can be used to heat tunnel kilns. Typical heat sources include coal,gas,and other fuel.
Tunnel Kilns are computer-controlled, continuously operating car-bottom kilns. Computer technology allows kiln car movement through the kiln to be controlled for changes in firing curves and firing temperatures. Automatic controls can be programmed to make firing changes for differences in product size and color.
Pushers move the train of cars non-stop at a predetermined rate. This method is ideal for all ceramic industries requiring high volume production and/or a continuous production process.
1.the fuel can be coal,gas,coal-gas,oil etc.
2.the investment budget will be depend on the automatic degree (project design and feasibility study, investment pay-back period
1. High efficiency: Speed up for green brick drying than the natural air drying.
2. Energy saving: waste heat from kiln, it could recovery the waste heat from kiln.
3. No influence by the bad weather, even in raining and wet/cold weather, could continuously operation for green brick
4. Saving your area and labor:If use dryer, it will use small area and labors than natural air drying.
5. It should have dryer, when you need cell brick with high hole rate or clay material.
6. Drying chamber is used together with kiln. It can speed up drying bricks taking the energy from the kiln, the production will not be influenced by rainy season or low temperature, such as in Bangladesh, India, Russian etc.
Vacuum extruder equipment is mainly used for extrusion of various brick types make of clay, shale, coal gangue, fly ash as raw materials. It can also be used for extrusion of high end building materials like split brick, tile and ceramic pipe etc.
Introduce from KWS company of Germany and receives the permission to produce in China with GFK trademark according to German standard.
This series equipment is well made in compact structure, good forming performance, high production efficiency, low power consumption, under the same extrusion pressure and production situation, it saves 20% of energy comparing with common vacuum extruder.
