Dry Roasting Equipment---Tunnel Roasting Kiln---The Mobile Rotary Tunnel Kiln

Product Description:

Tunnel roasting kiln can be divided into straight tunnel kiln (with kiln car) and mobile rotary tunnel kiln (without kiln car). Straight tunnel kilns can be further divided into masonry tunnel kilns and prefabricated tunnel kilns in terms of construction methods. The mobile rotary tunnel kiln belongs to the assembled tunnel kiln.

The Mobile Rotary Tunnel Kiln:

(1) Main products: sintered common bricks, porous bricks, hollow bricks

(2) According to the different output, the gauge of mobile rotary tunnel kiln can be divided into the following types:

① the gauge is 7.2 meters, suitable for 150,000-200,000 pieces per day (common bricks)

② the gauge is 8.6 meters, suitable for 200,000-300,000 pieces per day (common bricks)

③ the gauge is 10.8 meters, suitable for daily production of 300,000-400,000 pieces (common bricks)

④ the gauge is 12.98 meters, suitable for daily production of 400,000-500,000 pieces (common bricks)

⑤ the gauge is 16.8 meters, suitable for daily production of 500,000-600,000 pieces (common bricks)

(3) Kiln body structure

Using prefabricated structure, the kiln wall and kiln roof are factory processed into different units and spliced on site. Aluminum silicate refractory fiber is both the working layer and the insulation layer, and different thicknesses and materials are used in different temperature sections. The exterior is composed of steel frame and color steel plate and relates to the transmission mechanism to complete the movement of the kiln body.

(4) The drying and roasting of the mobile rotary tunnel kiln is completed at one time, and the length of the tunnel kiln is more than 160 meters. The diameter of the inner rail of the tunnel is greater than 78 meters, and the diameter of the outer rail of the tunnel is greater than 90 meters.

(5) Firing temperature: 900-1050℃

(6) Firing cycle: 48h
