The amount of free silica in the stone was 85–97%. Golbabaei et al. (2004) measured TWA concentrations of total dust, respirable dust, and crystalline silica (α-quartz) in a marble stone quarry located in the north-eastern region of the Islamic Republic of Iran. Full-shift (2 × 4-hour samples) personal breathing zone samples were collected ...
In the grinding of high quality fused silica parts with complex surface or structure using ball-headed metal bonded diamond wheel with small diameter, the existing dressing methods are not suitable to dress the ball-headed diamond wheel precisely due to that they are either on-line in process dressing which may causes collision problem or …
Recently, many correlation models between SSD and processing parameters, involving also the SR, have been developed, considering the kinematics characteristics of the machining process. For example, for grinding, Yao et al. [13] used the scratch fracture mechanics to develop a model between SSD depth and SR, which was related with the ...
When it comes to minimizing respirable silica, machines should utilize water during the cutting process, which helps to suppress silica dust by wetting the stone surface and reducing airborne particles. Additionally, CNC machines can be programmed, minimizing the need for manual intervention, and further reducing worker exposure to …

A ball mill, also known as a ball grinding machine, is a well-known ore grinding machine widely used in mining, construction, and aggregate applications.JXSC started the ball mill business in 1985, supplying global services including design, manufacturing, installation, and free operation training.
By contrast, granite contains only 10–45 percent silica content, and marble typically has less than 5 percent silica. Engineered stone slabs are made by crushing, blending, and compacting a unique ratio of quartz, polyester resin, and other additives. Because the quartz has already been crushed once, by the time fabricators polish or cut ...
Stone washing machine, also called sand washing machine, is used for desliming and screening a large number of sand and gravel in construction sites, sand and gravel factories, prefabrication plants, and hydroelectric construction sites, and can also be used for ore sorting operations.Stone washing machines can be roughly divided into …
Cutting stone, as pictured, generates dangerous crystalline silica dust that can become trapped in lung tissue and cause silicosis. This Hazard Alert focuses on countertop …
When processing stone containing crystalline silica, dust containing respirable crystalline silica (RCS) is released into the air. RCS can cause diseases such as silicosis in exposed workers. As crystalline silica content varies considerably in both engineered stone and natural stone, working with the higher silica content stone should be avoided.
