我厂是1964年由原古冶耐火厂、秦皇岛市耐火厂和石门寨矾土矿合并而成的。为了改变防尘落后面貌,1975年8月份,党委带领全厂职工在不影响全年生产计划完成的前提下,开展了一场安全防尘大会战,对主要产尘工序粉碎车间,用脉冲袋式除尘系统取代原来的水浴除尘系统,对原块料输送线进行有利于除尘的技术更新,基本实现了破碎工序的密闭和自动化。8月31日投产以来,该车间的矽尘浓度合格率由原来的13.15％猛增至63.6％,部分收尾工程完成后,预计可达70％以上。为便于湿式喷洒除尘,各车间用
I plant in 1964 by the ancient rule of the fire plant, Qinhuangdao refractory plant and Shimen Walled bauxite merged. In order to change the outlook of the dust-proof fall, in August 1975, the party committee led the entire plant workers without affecting the annual production plan under the premise of carrying out a dust-proof congress battle, the main dust production process crushing plant, using pulse bag Dust removal system to replace the original water bath dust removal system, the original block conveyor line for dust removal technology updates, the basic realization of the crushing process of the airtight and automated. Since the commissioning on August 31, the passing rate of silicon dust concentration in the workshop has risen sharply from 13.15% to 63.6%. After the completion of some of the projects, it is expected to reach 70% or more. To facilitate the wet spray dust, the workshop
