Limestone is one of the most versatile materials which are rich in resources. It is widely used in both industry and construction. Here we’re gonna talk about the most common uses of limestone—desulfurization in power plants. When limestone is used to desulfurize power plants, what are the requirements for limestone grinding? What kind of mashin din niƙa Shin ya kamata mu zaɓa? A nan za mu gabatar da su muku.
1. Bukatun injin farin ƙasa idan ana amfani da shi wajen cire sulfur a masana'antar makamashi
Generally, not all limestone flour can be used for desulfurization. Limestone flour for desulfurization requires not only powder fineness but also calcium carbonate content. In addition, there are also regulations on environmental protection during the grinding production. In order to ensure the comprehensive utilization of desulfurized gypsum and reduce the discharge of sewage, the content of calcium carbonate in the limestone should be higher than 90% when it’s used for desulfurization.
Kwarewar da ta gabata tana nuna cewa ƙaƙƙarfan ƙura na limestone (da ake amfani da shi wajen cire sulfur) a tashoshin wuta yawanci yana bukatar ya kasance tsakanin matsakaicin 200 da 325 meshes. Saboda haka yana bukatar cewa girman abun da ke fitowa daga injin niƙa ya dace da ma'auni. Ga masu ƙonewa da albarkatun mai masu ƙaramin ƙunshe sulfur, ƙaƙƙarfan ƙura na limestone ya kamata ya tabbatar da 90% na abubuwan da ke wucewa ta cikin super 250-mesh. Idan ana ƙona coal mai ɗauke da manyan sulfur, ƙaƙƙarfan ƙura na limestone ya kamata ya tabbatar da 90% na abubuwan da ke wucewa ta cikin super 325-mesh. Tabbas, za ka iya amfani da kalkali mai sauri (da tsaftar kalkali ya fi 85%) a matsayin mai shaƙewa.
