How to store better Shenyang gas filling block What about the raw materials of the equipment? today Aerator block The manufacturer's master will ask you for advice!

1. The raw materials of the aerating block equipment are transported by trucks to the warehouse in the plant, and the fly ash is transported to the raw material yard to be concentrated, and is loaded into the hopper when it is used; In terms of treatment, the fly ash is sent to the ball mill for grinding by electromagnetic oscillation feeder, provided by Star, and then transported to the slurry tank for storage by special fly ash loading equipment for better use of concrete aerating equipment;

2. Bagged cement and bulk cement need to be stored in the cement warehouse, and also loaded into the hopper when they are used. Cement and fly ash need to be equipped;

3. Chemicals used in the aerating block equipment shall be separated from other raw materials, put into the chemical warehouse, and shipped to the designated production workshop when they are used. The chemicals in the aerated concrete shall be made into a solution with a specific qualified concentration according to a certain proportion and sent to the storage tank for storage.

Pulverized coal boiler fly ash is generated by pulverized coal boiler incineration, and the burning fineness of pulverized coal boiler is less than 100 μ M high calorific value coal, high furnace temperature (generally above 1400 ℃), and the produced fly ash is quenched after high-temperature fusion.

Circulating fluidized bed incineration technology is a new generation of efficient, low pollution and clean coal-fired technology developed rapidly in the past two decades. The circulating fluidized bed boiler burns granular coal, and the slagging temperature is relatively low, generally 850 ℃~950 ℃. Under this temperature, SO2 and NOx emissions are greatly reduced; This furnace type is mainly planned for low-quality coal (ash content ≥ 30%), coal gangue and other fuels, and is the main furnace type developed recently.

There are great differences between pulverized coal boiler fly ash and circulating fluidized bed fly ash in mineral composition, microscopic description and loss on ignition. These characteristics not only directly affect the activity of fly ash, but also affect the quality of fly ash autoclaved aerated concrete products.

The specification Fly Ash Used in Cement and Concrete (GB/T 1596-2017) has clearly pointed out that fly ash does not include the following situations: (1) when burning municipal waste or other wastes together with fly ash; (2) Burning industrial or municipal waste in incinerators; (3) The collected powder is incinerated by the circulating fluidized bed boiler. Although the utilization mode of fly ash in this specification is different from that in the specification Fly Ash for Silicate Building Products (JC/T 409-2016), it still has certain reference meaning. Circulating fluidized bed fly ash should attract enough attention, and should be treated differently from pulverized coal boiler fly ash when used.

In production, the circulating fluidized bed fly ash cannot be used as all siliceous materials to prepare autoclaved aerated concrete. Generally, it is partially mixed. One fly ash is mostly stored in the open air, resulting in more caking and other impurities inside. In production, it is better to pass the ball mill to remove the impurities in it and obtain a better grading.
