Dust control vacuums for the mining industry. The DuroVac™ line of industrial vacuums can pick up a variety of sizes and types of material, from dust to 8in rocks, in wet slurries or very dry conditions. DuroVac vacuums pay for themselves within a short period of time, especially if the material has value.
· The dust kicked up by drilling through rock, particularly sandstone and granite, contains crystalline silica which can cause silicosis if inhaled. Silicosis devastated a number of mining communities in early days of industrialised drilling, but the disease persists today, especially in developing mining markets like South Africa.

Silica is usually exploited by quarrying and it is rare for it to be extracted by underground mining. Physical and Chemical Properties. The three major forms of crystalline silica -quartz, tridymite and cristobalite- are stable at different temperatures and have subdivisions. For instance, geologists distinguish between alpha and beta quartz.
Mining operations require very particular solutions for their unusual situations. RoboVent has decades of experience designing and manufacturing dust collectors to fit this kind of need. For example, RoboVent's Mobile series of dust collectors are built to move. No mining operation stands still, and neither can its air management equipment.

Scientists have known for decades that prolonged and excessive exposure to crystalline silica dust in mining environments can cause silicosis, a noncancerous lung disease. During the 1980's,
The main purpose of silica sand is the product expansion to make glass, casting, ceramics and refractory materials, smelting and other relevant. However, processing, processing for silica sand, according to different purposes appeared many for silica sand mining equipment, which is widely is silica sand crushing machine, milling machine and so on.
Moreover, Silica facilitates the audits of the products that we administer. As part of this service, Silica provides all technology including the ability to deliver a workflow solution within our customers business. The service includes a customized web portal utilising Silica's standard web parts and web services.
Mining, processing and transporting sand generate large quantities of silica dust, which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called "fracking," has led to boom in sand mining across the upper
Parts of Xuan Wei County, Yunnan Province, China have the highest known lung cancer mortality in nonsmoking women. This high mortality displays a clear spatial relationship to the mines producing coal from the uppermost Permian. Geochemical, petrographic, and grainsize analyses were undertaken on a set of coal samples from Xuan Wei. Results demonstrate that the single geochemical property that ...
