The highest median concentration of Fe (107 mg m-3) and Mn (28.7 mg m-3) was found in the inhalable fraction during plasma cutting and air carbon arc gouging, respectively. More than 40% of the inhalable PM generated during flame and plasma cutting, air carbon arc gouging and surface grinding was present in the respirable fraction.

Cutting (plant) - Wikipedia

A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation.A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil.If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking.A stem cutting produces new roots, and a root cutting ...

Suitable grinding jars of the MM 400 are made of steel or PTFE; single-use vials of 1.5, 2 and 5 ml are also available. Care must be taken that no liquid nitrogen is enclosed in the grinding jars. The frictional heat of the grinding process causes LN2 to enter the gaseous phase, resulting in a considerable pressure increase inside the grinding jar.

Refractometers Explained Coolant Consultants, Inc.

With most soluble oils the index is 1, so a refractometer reading of 5 multiplied by an index of 1 = 5% concentration. However, many semi-synthetics, synthetics, grinding fluids, and some soluble oils can have a refractive index from 1.5 to 3. So a refractometer reading of 5 multiplied by an index of 1.75 = 8.75% concentration.

Grinders - an overview ScienceDirect Topics

The particle diameter is controlled by the size of the holes in the mincer/grinder plate. They can vary from very large, the so-called ‘kidney plate’ (because of the shape of the holes) that produces fist-sized chunks, to 3 mm.. Some mincers/grinders are designed with a double plate that consists of a double-edged knife, or knife holder, sandwiched between a coarse plate of about 13 mm and ...
