1.绪言生产砖的设备很多,从国内来说已有几十种.国外就更多,并且自动化程度很高,发展也很迅速.1974年6月23日,国家建委、建材总局在西安召开了《全国砖瓦机械设备定型会议》,有几个省市,约40名代表参加,最后初步定了四种砖机:500挤砖机组(即50型),450双级真空挤砖机组(即45型),350挤砖机组(即35型),320双级真空挤砖机组(32型).32型主要用于生产瓦泥.另外还有干压砖机也有使用的,因为原料处理较困难,生产效率较低,所以还没有推广应用.
1.Introduction There are many equipments for producing bricks. There are dozens of kinds of products for domestic use. There are more foreign countries, and the degree of automation is very high. The development is also very rapid. On June 23, 1974, the State Construction Commission and the Building Materials Bureau were held in Xi’an. The “Construction Conference of National Machinery and Equipment for Brick and Tile Machinery” has several provinces and cities, and about 40 delegates participated in the project. Finally, four types of brick machines were preliminarily fixed: 500 Extruded Brick Units (ie 50 Type) and 450 Double-stage Vacuum Extruded Brick Units ( Type 45), 350 Extruder (ie Type 35), 320 Duplex Vacuum Extruder (Type 32). Type 32 is mainly used for the production of tile mud. In addition, dry presses are also used because of raw material handling. It is difficult and the production efficiency is low, so it has not been popularized and applied.
