Coarse sheet

Shelf (elastics) Sheet-like sandbodies resulting from storms or transgression. Usually thin but very continuous sands, well sorted and coarse between marine clays. Very high productivity but high quality sands may act as thief zones during water or gas injection. Action of sediment burrowing organisms may impact on reservoir quality. 

In order to dry the crystals, the Buchner funnel is inverted over two or three thicknesses of drying paper (i.e., coarse-grained, smooth surfaced Alter paper) resting upon a pad of newspaper, and the crystalline cake is removed with the aid of a clean spatula several sheets of drying paper are placed on top and the crystals are pressed flrmly. If the sheets become too soiled by the mother liquor absorbed, the crystals should be transferred to fresh paper. The disadvantage of this method of rapid drying is that the recrystallised product is liable to become contaminated with the Alter paper flbre. 

Asphalt-coated glass fiber venting base sheet with fine mineral surfacing on the top side and coarse granules on the bottom side perforated/embossed or not. The coarse granules provide an open, porous channel in the horizontal plane (5,11). 

The physical nature of the material to be handled is the primaiy item for consideration. A slurry will demand a different type of diyer from that required by a coarse ciystaUine solid, which, in turn, will be different from that required by a sheet material (Table 12-9). 

The hybrid circuit in Fig. 20-26 has proven most versatile, and can increase capacity of an existing ball-mill circuit by 30 to 100 percent. Recycling the rock as in the hybrid flow sheet reduces the need for coarse-b milhng. 

A flow sheet for one iron ore process is shown in Fig. 20-56. For the grinding of softer copper ore the rod mill might be eliminated, both coarse-crushing and baU-milhng ranges being extended to fill the gap. 

Flexible metallic media are especially suitable for handling corrosive liquors and for high-temperature filtration. They have good durability and are inert to physical changes. Metallic media are fabricated in the form of screens, wire windings, or woven fabrics of steel, copper, bronze, nickel and different alloys. Perforated sheets and screens are used for coarse separation, as supports for filter cloths or as...

To accommodate efficient heating of coarse solids, it would be desirable to break the fall of these particles during their descent by means of baffles in order to prolong their residence time, as shown schematically in Fig. 13 (Kwauk, 1979b). In this respect, a good baffle needs to cover up to 100% of the cross-sectional area traversed by vertical flow, and yet permit oblique passage as near to 100% as possible. Also, baffles should distribute solids laterally in order to give uniform solids population in the heat transfer apparatus. Thus, conceptually, an ideal baffle plate should consist of a cellular array, structurally robust, of deflectors made of infinitesimally thin sheet materials.

Alliger (U.S. Patents 3,659,402,1972, and 3,905,788,1975) describes fiber-bed structures which are not random, but are rather built up from flat mesh sheets offset angularly from one layer to the next and then compressed and bonded. Such bonded beds of relatively coarse hydrophobic fibers both are remarkably flushable, to prevent fouling by insoluble solids, and have surprisingly high collection efficiency per unit pressure drop for submicrometer particles, approaching that of irrigated fine hydrophobic fiber filters such as described by Fair (U.S. Patent 3,135,592, 1964) and Vosseller (U.S. Patent 3,250,059, 1966). 

Aluminum dust and fine powder are highly explosive and can spontaneously burst into flames in air. When treated with acids, aluminum chips and coarse powder release hydrogen. The heat from the chemical reaction can then cause the hydrogen to burn or explode. Pure aluminum foil or sheet metal can burn in air when exposed to a hot enough flame. Fumes from aluminum welding are toxic if inhaled.
