1. Introduction. Barium slag (BS) is a hazardous industrial solid waste formed during the production of barium carbonate from barite. BS contains a lot of soluble barium ions (Ba 2+) with a leaching concentration 2–20 times higher than the regulation limit of hazardous waste in China (GB 5085.3–2007) [].In addition, the leaching rate of Ba 2+ in BS can exceed 90% in acidic …
However, wollastonite grinding powder has always used dry processes such as Raymond mill machine, impact mill or air mill. Although the fiber structure of the product can be retained, there are process level restrictions in the realization of ultra-fine wollastonite.
Barium minerals are dense (e.g., BaSO 4, 4.5 grams per cubic centimetre; BaO, 5.7 grams per cubic centimetre), a property that was the source of many of their names and of the name of the element itself (from the Greek barys, "heavy").Ironically, metallic barium is comparatively light, only 30 percent denser than aluminum.Its cosmic abundance is estimated as 3.7 atoms (on a …
Small amounts of water-soluble barium may cause a person to experience breathing difficulties, increased blood pressures, heart rhythm changes, stomach irritation, muscle weakness, changes in nerve reflexes, swelling of brains and liver, kidney and heart damage. Barium has not shown to cause cancer with humans.

Barite is an important barium-containing mineral, with high specific gravity (4.3-4.7), low hardness (3-3.5), stable chemical properties, insoluble in water and acid, barite can be used as a white pigment (commonly known as Lith Powder), can also be used in the chemical industry, papermaking, textile fillers and other industrial sectors. In the glass production, it can …
Munson's Pin Mill, or "Centrifugal Impact Mill," reduces bulk materials into narrow particle size ranges without the need for screens, hammers, knives or rolls. Instead, it relies on material impacting hundreds of pins thousands of times as it travels from the center to the periphery of the milling chamber.

Barium stimulates striated, cardiac, and smooth muscle, regardless of innervation. It is antagonistic to all muscle depressants, no matter whether they act primarily on nerve or muscle. Initial stimulation of contraction leads to vasoconstriction through direct action on arterial muscle, peristalsis through action on smooth muscle, tremors and cramps through action on the …
