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:

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

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

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

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

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


Q:What is a combination of drying equipment?
Combination drying equipment is a combination of two or more dry forms, the main material, mainly in series, that is, when the material has been through the drying equipment, two or more drying equipment, combined dry mainly to meet a The need for a drying process.
Q:What are the characteristics of the drum dryer?
The main body of the rotary drum dryer is a slightly tilted and rotatable drum, and the wet material is fed from one end thereof and passes through the inside of the drum and is dried in contact with the hot air or the heated wall in the cylinder. , Chemical industry, metallurgy, building materials and other industries have a wide range of applications. Rotary drum drying and other drying equipment compared to the production capacity, continuous operation and simple structure, easy operation and less trouble, low maintenance costs
Q:What are the common types of dryers?
The belt dryer consists of a number of individual unit segments, each of which includes a circulating fan, a heating device, a separate or common fresh air extraction system and an exhaust gas extraction system. The amount of drying medium, temperature, humidity and exhaust cycle
Q:What are the basic types of common drying equipment?
(4) hollow paddle dryer (leaf dryer) hollow paddle dry dryer, also known as leaf dryer, mainly by the jacket with the W-shaped shell and two hollow blade shaft and transmission components. A hollow blade is arranged on the shaft and a rotary joint with a heat medium inlet is provided at the shaft end. The heat required to dry the moisture is conducted to the material by the inner wall of the W-shaped groove with the jacket and the hollow leaf wall.
Q:Frozen sublimation drying equipment which consists of several systems
the vacuum system: by the freeze-drying room, condenser, vacuum valves and pipes, vacuum equipment and vacuum instrument composition, the current vacuum equipment is extremely combination of three: the Roots pump, cryogenic condenser, and multi-stage steam ejector, which , Multi-stage steam ejector structure is simple, no mechanical power, easy maintenance, low failure rate, the material requirements are not high, usually need to set 4-5 level.
Q:What are the types of drying equipment?
the drying medium, the thermal efficiency is high, the product is not polluted, but the drying capacity by the metal wall heat transfer area limit, the structure is also more complex, often in vacuum operation; radiation dryer is the use of various radiation Emitting a certain wavelength range of electromagnetic waves, the wet material surface is selectively absorbed into heat after the dry; dielectric dryer is the use of high-frequency electric field effect, so that the wet material inside the thermal effect of drying
Q:How to solve the dryer a series of failures
If the dew point reading is normal after the dry machine is replaced, the dew point rises rapidly after the end of the drying cycle of the dryer, indicating that the ambient air may enter the closed gas path, causing the dryer to absorb prematurely. Another possibility is that the dryer is not completely regenerated or contaminated. If the dew point reading and reflow air dew point readings are close, it indicates that the regenerative gas path is completely failing or the desiccant is seriously polluted.
Q:What are the common drying methods?
Is the use of moisture to remove gas, liquid, solid material in a small amount of water, due to moisture dehumidifier dehumidification capacity is limited, only used to remove trace moisture in the material, so the production of very little.
Q:The working principle of belt dryer
Material from the feeder evenly spread on the mesh belt, mesh with 12-60 mesh stainless steel mesh. Moved by the drive in the dryer. The dryer consists of several units, each unit of hot air independent cycle, part of the exhaust by a special exhaust fan discharge, the exhaust gas from the control valve control, the heat from the bottom up or from top to bottom through the shop in the material on the net, heating Dry and take away moisture. The mesh belt is slowly moving, the running speed can be adjusted according to the material temperature freely, and the dried finished product falls into the feeder continuously. Up and down the cycle unit according to user needs can be flexible equipment, the number of units can be selected according to need.
Q:What is the best drying equipment?
In the traditional horizontal fan-type dryer, the air flow only in the material surface flow, the drawback is the low heat transfer coefficient, poor heat utilization, material drying time is long.
