        Quartz Sand Crushing Process

        Author:REPUBLICA Post Date:2012-4-28

        Occurrences of Quartz Sand

        This is a rare occurrence because in most environments the Quartz Sand tend to be altered to other substances, such as clay minerals. They also may be found in many metamorphic rocks formed from precursor rocks that contained Quartz Sand and/or the stone elements required for their formation. In addition, Quartz Sand occur in veins and pegmatites, in which they were apparently deposited by fluids, and within sediments and soils, in which they were probably deposited by groundwater solutions. Some of the typical occurrences for the individual species are given in the table. Morocco, China, India, Indonesia, Japan, Laos , North Korea, Singapore, Thailand , Vietnam, Belgium, Bosnia and Herzegovina Bulgaria, France, Germany , Italy Kazakhstan, Netherlands, Norway, Russia, Slovakia, Spain, UK, Argentina, Bolivia, Colombia, Guatemala, Mexico, Peru, Canada, Trinidad and Tobago, United States (USA), Australia, Iran, Kuwai, Turkey, United Arab Emirates (UAE), etc.

        Quartz Sand Crushing Process

        Quartz Sand crushing process and the process is mainly divided into the following aspects:
        Crushing Process
        ① a broken process. A broken process is generally used to provide the right from the feed mill, often constitute a system with self-mill. The process is simple, less equipment, plant and small footprint.
        ② two crushing process. The mostly small-scale plant using the process.
        ③ three sections broken process. The basic form of the process open and three sections of three sections of a closed two.
        ④ work with broken washing process. When the feeding of the mud (-3mm) of more than 5% to 10% and water content greater than 5% to 8%, should increase in the crushing process Quartz Sand washing operations.

        Grinding and Classification Process Procedures

        In terms of dressing, using a grinding or two can put the economy grinding to a mineral Quartz Sand to any size needed. Two or more grinding, usually elected by the other requirements of the decision stage.

        Period and compared to two processes, a grinding process of the main advantages are: less equipment, low investment, simple operation, do not stop because of a grinding segment to another segment of the work of grinding, less downtime losses. But the mill to the Quartz Sand particle size range, a reasonable ball hard, not easy to get the final product of smaller, low grinding efficiency.

        When asked the maximum particle size of the final product of 0.2 ~ 0.15mm (or 60% to 79% -200 mesh), generally used a grinding process. Small factories, in order to simplify the process and device configuration, when the grinding fineness required 80% -200 mesh, we also used a grinding process. Two outstanding advantages of grinding can be smaller products, in different sections coarse grinding and fine grinding, especially for stage process.

        In large and medium-sized factories, as required grinding fineness is less than 0.15mm (ie 80% -200 mesh), using two grinding more economical, and uniform particle size composition, was less than smashing. Under the first paragraph of the mill is connected with the classification of different ways, the two grinding process can be divided into three types: the first open; second paragraph of the entire house; first local house, and the second is always closed circuit grinding work process.

        Grinding Process

        Since the grinding process is classified to dry and wet. Concentrator to use more wet. Since the mill in order to solve the difficult problem of wear particles to improve grinding efficiency, adding a small amount from the ball mill, then known as the semi from the mill.

        Since the constant grinding and crushing, milling, grinding Quartz Sand crushing equipment, joint work, based on their association composed of a variety of ways to process.
