Problems solved by technology

In the production of iron-making or calcined cement of this kind of well-type kiln, the materials entering the kiln are only spherical materials with a relatively small diameter, and the air permeability in the production of the well-type kiln is not very good. The poor air permeability of the well-type kiln will affect the quality of the product. yield and quality

Embodiment 1

[0009] Embodiment 1. When using a well-type kiln for ironmaking or calcining cement, the kiln material is added from the top of the kiln, and the burnt product is taken out from the outlet of the kiln bottom. In the kiln material, there are spherical materials in the prior art. In the material, when using a well-type kiln to make iron, in the pellets of 10-20 mm or in the case of calcining cement in a well-kiln, in the raw meal balls of 10-25 mm, there are evenly mixed wood blocks, wood blocks The size is that the length of the longest part of the wooden block is 50-60 mm, and the length of the shortest point is 10-60 mm. The addition of the wooden block is that the volume ratio of the wooden block to the spherical material in the prior art is 0.2-0.4 , the material of the wooden block is the stem, root, fruit core or / and husk of the plant, and the wooden block is a massive wooden block processed from the stem, root, fruit core or / and husk of the plant, and the processed wooden...

Embodiment 2

[0010] Example 2. In calcining cement in a well-type kiln, the kiln materials are added from the top of the kiln, and the burnt products are taken out from the outlet of the kiln bottom. Among the materials entering the kiln, there are spherical materials, and the spherical materials include solid raw meal balls and wood. The raw meal balls with material cores, solid raw meal balls and raw meal balls with wooden material cores are evenly mixed with wooden blocks. The size of the essential blocks is that the length of the longest part of the wooden block is 50-60 mm, and the length of the shortest part is 10-60 mm, the addition of wooden blocks is such that the bulk volume ratio of the wooden blocks to the spherical material in the prior art is 0.2-0.4. The material of the wooden block is the stem, the root, the core or / and the husk of the plant, and the wooden block is a massive wooden block processed from the stem, the root, the core or / and the husk of the plant, and the proce...

Abstract

The mad of raising air permeability for well-type kiln to make iron or calcine cement is to add wood blocks into the material fed to the kiln from the kiln top. The wood blocks have sizes with maximum value of 50-60 mm and minimum value of 10-60 mm and the added amount is 0.2-0.4 of the spherical material volume. The addition of the inflammable wood blocks can raise the air permeability of well-type kiln effectively to raise the yield and quality of the product of the kiln.

Description

technical field [0001] The present invention relates to a method for improving air permeability in pit-type kiln ironmaking or calcining cement, in particular to the composition and proportion of kiln-feeding materials in pit-type kiln ironmaking or calcining cement. Background technique [0002] Well-type kilns can be used for ironmaking and cement calcining. When using pit-type kilns for ironmaking or cement calcining, materials are added into the kiln from the top of the kiln, and fired materials are taken out from the outlet of the kiln bottom. When pit type kiln is used to make iron or calcined cement, the materials entering the kiln are spherical materials, that is, during iron making, the materials entering the kiln are iron ore powder, which is made into iron ore powder balls on the ball forming plate, and then the iron ore powder balls are preformed Sintered pellets; when calcining cement, the kiln material is the raw meal balls that are made by feeding the raw meal...
