在耐火材料厂的防尘工作中,一般把注意力集中到破碎、筛分、运输设备上,而对作为主要成型设备的摩擦压砖机的防尘未引起重视。在破碎、筛分、运输作业场所的粉尘浓度逐渐接近或达到国家卫生标准的情况下,相对地,摩擦压砖机作业区的矽尘危害就日益显得突出。摩擦压砖机生产时,扬散的粉尘量虽然较少,但是在一个厂房内在在安装了成批的摩擦压砖机,当它们同时工作时,所扬散的粉尘对厂房内空气的污染非常严重。因此,作好主要成型设备摩擦压砖机的防尘工作,是
In the dustproof work of refractory plants, attention has generally been focused on the crushing, screening and transportation equipment, and dust-proofing of the friction brick pressing machine, which is the main molding equipment, has not been taken seriously. In the crushing, screening, transport operations, the dust concentration gradually approaching or meet the national health standards, relatively, friction brick operating area of the hazards of silica dust is increasingly prominent. Friction brick press production, although the amount of scattered dust less, but in a plant within the installation of a batch of friction brick press, when they work at the same time, the dust scattered on the plant air pollution is very serious. Therefore, make the main molding equipment friction brick press dust work is
