我们为了解决坯子密度大,不易排水,表里干燥不一致,测定了哈尔滨市第二制砖厂的“木龙口”规格。其长度为200厘米;后口宽290;前口宽247;锥度率10.75%;后口高160;前口高118;锥度率10.5%,故大于苏联制砖机“龙口”锥度,因此产量低。以含水率20%的原土掺兑25%瘦化剂的原料计划每班仅产11,900块。 In order to solve the problem of large billet densities, difficulty in drainage, and inconsistent dryness in the table, we measured the “Wood Longkou” specification of Harbin Second Brick Factory. Its length is 200 centimeters; the rear mouth width 290; the front mouth width 247; the taper rate 10.75%; the rear mouth height 160; the front mouth height 118; the taper rate is 10.5%, therefore is larger than the Soviet Union brick machine “Longkou” taper, therefore Low Yield. The raw material blended with 25% of the lean-incining agent in the original soil with a moisture content of 20% is planned to produce only 11,900 per shift.
