Meanwhile, in the brick factory in the prior art, the proportioning is carried out by adopting off-line weighing and metering in the process of making the brick skin, so that the efficiency of firing the green bricks is greatly reduced. The weighing method cannot timely and effectively adjust errors generated in the material preparation process.
With the continuous development of wall material reformation, clay is gradually changed into new raw materials such as coal gangue and shale for producing the baked brick. The production line of the baked brick is built by adopting the novel material all over the country. The sintered product is also developed from the traditional standard brick and is called as a sintered perforated brick and other various products. However, the practicality of the novel material brings new problems, and a plurality of brickyards face the embarrassing situation that qualified products are difficult to produce.
