the plants, constituting 40% of herbal preparation. This was followed by the roots which constituted 30% while corms, twigs and whole plant were rarely used for the preparation of the medicines. The commonest method of herbal preparation was infusion (Table 1). This is made by boiling pulverized or loose plant materials in water.
11.19.2. Previously, information concerning this segment of the crushed stone industry has not been available in AP-42. Data concerning pulverized mineral processing operations are a logical extension of stone crushing plant data because (1) the quarry, initial crushing, and screening operations are identical to
crushed to coarse powder. Extraction of the Root Bark The pulverized plant sample (1000 g) was macerated successively in n-hexane, ethyl acetate, chloroform and methanol exhaustively until complete extraction. 4.4.

bacteria was seeded on molten Mueller-Hinton agar plate. Using a sterile corn borer of 6 mm diameter, equidistant wells was made in the agar. One millimeter of the various re-suspended extracts (7.5, 15, 30 and 60 mg / ml) was introduced into the wells. The plates were allowed to stand on the bench for 1 hour, to allow pre-diffusion of the extracts
2.2. Preparation of plant extracts The air dried leaves of P. hispida were pulverized and one hundred and fifty grams (150g) of the powder macerated in two and a half litres (two thousand five hundred millilitres) (2.5L) of methanol inside clean solvent bottles.

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...

Pulverized plant material (600 g) was degreased by Soxhlet extraction in several batches of 150 g each with 600 mL petroleum ether (Roth) over a period of 7 h. The resulting extracts were combined and evaporated under vacuum (m = 18.65 g; corresponding to 3.09%).
Pulverized fuel ash is a residue resulting from the combustion of ground or powdered or crushed bituminous coal or sub-bituminous coal (lignite). About 80 percent of the total ash is finely divided and get out of boiler along with flue gases and is collected by suitable technologies. This ash generally and in this standard is termed as fly ash.

1. Pulverized Coal Burners 1.1. Pulverized Coal Supply Pulverized coal from the coal pulverizers is conveyed in a stream of hot primary air from the mills to the burners where it is injected into the furnace space to be burned. Generally, the air–fuel ratio of the fuel mixture leaving the pulverizers is about 2:1 for
one. A PLI value close to one indicates heavy metal loads near the background level, while values above one indicate soil pollution (Cabrera et al., 1999; Liu et al., 2005). A modified and generalized form of Hakanson (1980) equation for the calculation of the overall degree of contamination was defined as the sum of all contamination factors (C f
(a) Produce Crushed Stone (CS-1) and Crushed Stone Screenings (CS-2) by crushing limestone, sandstone, porphyry, (rhyolite, basalt, granite, and Iron Mountain Trap Rock are examples of porphyry) or other types of stone. (b) Produce Crushed Gravel (CG) by crushing siliceous gravel containing not more than 15% non-siliceous material.
The two methods used to feed the pulverized fuel to the combustion chamber of the power plant: 1. Unit System 2. Central or Bin System. In unit system, each burner of the plant in fired by one or more unit pulverizers connected to the burners, while in central system, the fuel is pulverized in the central plant and then distributed to each furnace with the help of high pressurized air currents ...
Coal-fired power plants are highly complex systems. The . type of plants chosen for this study are commonly referred to as pulverized coal (PC)-fired plants, where the coal is crushed to a fine powder in a pulverizer in order to increase the surface area for injection into a …
Lime, sometimes known as agricultural lime, is crushed or pulverized limestone which is primarily comprised of calcium carbonate. It is commonly used in products such as plaster, mortar, concrete, chalk, and even in antacid heartburn medications. The ultimate goal of is to increase alkalinity.

For preparing of extracts, plants were properly dried and pulverized into a coarse powder. Each of 40 g grinded powders was soaked in 50 ml ethanol 95%, separately for 20 h (shaking occasionally with a shaker). After one day of dissolving process, materials were filtered (Whatman no. 1 filter paper).

(i) Processes. Combustion of pulverized coal in entrained or suspended beds in utility and industrial boilers is by far the most common method of coal use. The run- of-mine coal is crushed, dried, and pulverized to fine powder in a crusher and a pulverizer or mill. Typically, 70 to 80% of the pulverized coal particles pass through a
