After mining, the materials are transported to the sandstone processing plant by belt conveyors, or other means. From the hopper, the material is transported to a fixed or vibrating screen by gravity, belt conveyors, hydraulic pump, or bucket elevators.Sand and gravel are often mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels and bucket wheel excavators. The wet sand and gravel raw material will be fed directly into a hopper. Oversize material may be used for erosion control, reclamation, or other uses, or it may be directed to a crusher for size reduction, to produce crushed aggregate, or to produce manufactured sands. The vibrating screens separate the oversize material from the smaller, marketable sizes.
The principal object of the invention is to develop a method for crushing concretions in the urinary bladder and to provide an instrument for realization of this method which would exert, on the stone to be crushed, remotely controlled actions varying in their character and intensity.
It should be noted that; above content is in conjunction with concrete embodiment further description made for the present invention; can not assert that the specific embodiment of the present invention is only limitted to this; under above-mentioned guidance of the present invention; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion drops in protection scope of the present invention.
An additional object of the invention is to reduce sensitivity to the environment, to permit the machine to operate at lower temperatures and in water-scarce areas. An ancillary object is to permit release of relatively precise proportions of the various size ranges, to facilitate the formation of an aggregate mix to specification. A further object of the invention is to perform the desired washing and classification with high throughput, while not requiring as large a machine as was heretofore needed and while keeping wear to a minimum. A second object of the invention is to remove as much undesirable matter from an aggregate mix as reasonably possible.A first object of the invention is to provide an efficient and effective method and apparatus for washing and classifying an aggregate. Yet another object of the present invention is to enable the apparatus for washing and classifying to be portable without significant disassembly or labor, such that the apparatus may readily be transported as a trailer or load upon a vehicle from location to location. Another object of the present invention is to quickly and efficiently classify the aggregate mix into appropriate size ranges.
% in H2O and (2–3) cP in 15% H2O .5 °C melting point and 138 °C flash point.11 g/cc at 25 °C in 50 wt. Polyacrylamide has a high molecular weight water soluble or swellable polymer. The properties of polyacrylamide solution are 4–6 pH and 1. New developed chemical materials like polyacrylamide polymer were used for consolidating the grain sand of the formation.The chemical sand consolidation methods discussed above have some unfavorite feature such as multiple phases for consolidating, environmental unfriendliness, less compressive strength and difficulty of surface pumping and handling. The properties of acrylamide are 1. Polyacrylamide polymer can be a polymer, which can be obtained from acrylamide subunits, Figure 10.322 g/cc density, 84. The acrylamide can be an organic compound with the chemical formula CH2=CHC(O)NH2.
