Silica is the most abundant mineral in the earth's crust. Unfortunately, breathing in silica dust caused by chipping, cutting, drilling, or grinding soil, granite, slate, sandstone or other natural materials can lead to chronic lung disease.
Using a concrete grinder: Technique matters. When grinding concrete, take your time and allow the machine to do its work. If you move too fast, odds are you'll end up redoing some areas. The way you move the grinder depends on the type you're using. Single disc or duel-disc rotary grinder: Swing the machine from side to side.
Grinding can cause heat buildup and thermal stress, leading to surface discolouration or even cracking in the material. It can be a time-consuming and labour-intensive process, especially for large-scale projects. Grinding can produce dust that can cause respiratory issues and create a safety hazard. Difference Between Sand Blasting …
