Refractory bricks are mainly used in steel, cement, glass and electric power. In these industries, kiln equipment needs to be removed after the service cycle. At the same time, it has always been a question mark around the users. I don't know how to deal with it. Let's analyze and answer it today. Can it be recycled again? What are the uses of waste refractory bricks? How much is waste refractory brick crushing equipment?
1. How to deal with waste refractory bricks?
Generally, refractory bricks are used in every new high-temperature kiln, and some high-temperature kilns are basically built with refractory bricks except the steel structure furnace shell. For example, the whole coke oven type in coking plant is built with refractory bricks, which is widely used, so a large number of waste bricks are produced, At present, through certain technical means, we can further improve its utilization value and reduce the cost of raw materials.
Treatment method of waste refractory bricks:
01. Waste brick is used as raw material, that is, it is used as slag making material during smelting and refining;
02. After classifying and crushing the waste bricks, the ingredients and granularity should be adjusted to make use of refractory materials, including the used waste refractory brick regeneration technology, and the waste refractory bricks can be used as raw materials such as unshaped materials.
2. What are the uses of waste refractory bricks?
01. After screening, sorting and crushing in the refractory plant, select appropriate raw materials to make the aggregate and powder of refractory bricks;
02. Waste brick is used as raw material, that is, it is used as slag making material during smelting and refining;
03. It can replace river sand as fine aggregate;
04. Waste refractory bricks can be used as road materials;
Use value of waste refractory bricks of different materials:
Waste silica refractory bricks: it is also cost-effective to add waste silica bricks as raw materials for new silica bricks in silica brick production, which can reduce a large part of the cost of silica bricks, reduce firing expansion and reduce firing waste rate, especially for large and special products with complex shapes. More waste silica bricks should be added to improve the yield, but it should be noted that, The addition of waste silica brick will also reduce the fire resistance and mechanical strength of the products. To control the addition amount, it is generally better to be less than 20%.
High alumina and clay waste refractory bricks: after selection and crushing, they can be added to the clinker of newly produced refractory bricks, or the crushed particles can be graded and proportioned into low-grade refractory castable or refractory concrete, or they can also be finely ground into refractory mud and refractory soil of different materials.
3. What equipment is used for crushing waste refractory bricks?
Refractory brick is generally made of refractory clay or other refractory raw materials. Its shape has standard rules and has good compression resistance, bending resistance and wear resistance. What equipment is good for crushing waste refractory brick? According to its characteristics, it is recommended to use jaw crusher and mobile crusher, which can be reasonably purchased in combination with output demand, site conditions, investment budget and other aspects.
4. How much is waste refractory brick crushing equipment?
Generally speaking, waste refractory bricks have high recycling value and are a good industry. According to the current market understanding, the prices of waste refractory brick crushing equipment are different. The larger the model and output, the higher the price will be. At the same time, the material selection, workmanship level and product service of each crusher manufacturer are not exactly the same, which will lead to different prices, Therefore, it is also very necessary to go to the manufacturer to inspect the spot.
How much is a waste refractory brick crushing equipment? You are welcome to consult for free. The technical manager will send you details, videos, schemes, etc. at any time. Moreover, SMMVIK Machinery is produced and sold by itself, which is cheaper than middlemen. At the same time, it has strict ex factory quality standards and sufficient goods.
