    • A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel. The grinding sludge containing the oil-based coolant and hardened component parts such as steel component parts that are used in bearings is compressed. To this end, the grinding sludge produced from a grinding line (1) is filtered by a filtering unit (4) to provide a concentrated sludge which is subsequently compressed by squeezing by a briquetting machine (5) to provide the briquette (B1). The briquette B1 so obtained can be reused as steel material. The coolant separated from the grinding sludge during filtering and squeezing is returned to the grinding line (1) through recovery passages (7, 8).
    • 一种用于压缩研磨污泥的方法和装置,其有效地压缩研磨泥浆以提供预期的刚性团块,即使研磨污泥含有硬化铁和/或钢材料的研磨碎片和油基冷却剂,以及 以便于将煤块(B1)作为生产钢材的再利用。 包含油基冷却剂的研磨污泥和用于轴承的钢组分部件等硬化部件被压缩。 为此,由研磨线(1)产生的研磨污泥由过滤单元(4)过滤以提供浓缩的污泥,随后通过压块机(5)的挤压压缩以提供压块(B1)。 如此获得的团块B1可以作为钢材重复使用。 在过滤和挤压期间从研磨污泥分离的冷却剂通过回收通道(7,8)返回到研磨生产线(1)。
