SANITARY WARE PRODUCTION 卫 生 瓷 生 产 1. PRECRUSHING OF RAW MATERIALS 原 料 初 碎 Hard materials (硬质料) like feldspar 长石，quartz (石英)，may be precrushed (初碎)，in order to reduce (减少) the grinding (研磨) time during preparation (制备). The hard materials are charged (装) to an impact crusher (锤击破碎机), for reducing (缩小) the grain size (粒度). A vibrating sieve (振动筛) separates oversized (过大的) grain, which is returned (返回) to the crusher (破碎机). The crushed (破碎过的) materials are stored in silos (料仓). Zircon sand (锆英砂) has to be ground (研磨) in a ball mill (球磨机) to a maximum (最大) size of 100 micron (微米) and is then ground in a vibro-energy-mill (振动磨) to the final sizes. 参考译文： 1、原 料 初 碎 为了缩短原料制备过程的研磨时间，诸如长石，石英之类的硬质原料可先进行初碎。将这些硬质料放进锤击破碎机内缩小其粒度。较大的颗粒由振动筛分离出去，返回破碎机。 破碎过的原料储存在料仓内。锆英砂应在球磨机内研磨，使最大粒度不超过 100 微米，然后再放入振动磨内研磨到所需要的粒度。 2. BODY PREPARATION 坯 料 制 备 According to （按照）the composition （配方）, the raw materials are taken out of the boxes by a shovel loader（装载机）, weighed（称重）on a platform scale （台秤）and dumped（倾倒）into a box feeder （加料箱）. The amount loaded into the box feeder is recorded by the shovel loader driver. As soon as a batch（批料）is collected in the box feeder, a ball mill （球磨机）can be charged （加料）. The materials leaving the box feeder pass a clay（粘土） slicer （切碎机）in order to cut chunks（大块）of clay to smaller size for easy dissolving（细碎）of the clay in the ball mill. By means of（通过）conveyor belts（输送带）the raw materials are transported into the ball mills. After adding the right amount of...
