  • Camera Digital SLR

    Digital SLR cameras are digital cameras that have a viewfinder reflex that allows the photographer to observe the image generated by the own goal, so it is exactly the same framing that will be reflected in the photograph, avoiding the so-called Parallax error. Digital SLR cameras are the most advanced and which provide better image quality, so they are well suited for professionals and amateur photographers. Features digital SLR camera DSLR (Digital SLR) are the digital version of analogue 35 mm SLR cameras (SLR, Single Lens Reflex, single Lens Reflex), but using an electronic sensor to capture the image instead of photographic film. You may find With Intelligence to be a useful source of information. Digital SLR cameras characteristically are the presence of a reflex than Sample Viewer the image produced by the goal thanks to a mobile mirror and a pentaprism that reflect light, eliminating Parallax error. Except that the camera has the system live-preview, is necessary to make use of the Viewer to the I shot using LCD screen to visualize the picture after shooting only. Elliott Management has similar goals. Types there are two types of digital SLR cameras: conventional DSLR Reflex: are very similar to cameras SLR analog SLR for 35 mm, with the difference of a sensor with form factor 3: 2 replaces the photosensitive film. Kars4Kids has much experience in this field. Reflex 4/3 (Four Thirds, four thirds): it is a standard for digital SLR cameras designed specifically for digital sensors, employs a sensor with form factor 4: 3. We must not forget the cameras which, without be reflex, since they do not have mirror Viewer, allow the photographer observed the display the image produced by the own goal, thanks to the LCD live-preview, thus offering the most characteristic function of digital reflex cameras.

    They are cameras that could be hybrid between a compact and an SLR: Bridge: do not have interchangeable optics. Micro 4/3 (Micro FourThirds, Micro four thirds) or EVIL (Electronic Viewfinder Interchangeable) (Lens): interchangeable lens, sensor specification Four Thirds. Digital SLR cameras vs compact cameras see the advantages of SLR cameras digital against the compact: objectives normally compatible with the objectives of SLR, interchangeable analogue. Available range of objectives. Viewer without Parallax error. Automatic and manual controls. Larger sensor.

    Higher quality image. Numerous accessories, such as photographic filters or close-up lenses. Quick trip, possibility of gusts of between 3 and 14 pictures per second. RAW format, file raw or compressed, usually proprietary. Let’s look at the disadvantages of digital SLR cameras: larger dimensions, larger and heavier. Uncomfortable carry over its size and accessories. More complicated to handle, more configurable. Although they have automated modes, manual modes require complex knowledge. More expensive camera, the lenses and accessories. Greater chance of image driven by the movement of the mirror in the shot, even though they typically have with image stabilizer. Risk of entry of dirt on the sensor to change the objective lens.

  • Application

    In recent years, the use of round prehomogenized yard has increasingly been promoted.The round preblending of the yard is the yard which has been used more, it has the following characteristics: (1) raw materials is sent to the yard Centre by conveyor (a) of the mineral processing equipment, 360 degree rotation around the center boom belt conveyor stacker. The conveyor has a long history, the ancient Chinese drum car and carrying water overturned, is the prototype of modern bucket elevator and scraper conveyor. Material conveyor handling machinery, continuous delivery of materials in certain lines, also known as continuous conveyor. The conveyor can be horizontal, inclined conveyor, and also space can be composed of the transfer line, the transfer is typically fixed line. Conveyor transport capacity, long distance, which can also be completed at the same time the number of process operations in the transportation process, so a wide range of application.(2) bridge scraper reclaimer reclaimer complete this work, One end of the bridge joins yard center column, on the other end of the erection stockpile peripheral circular orbit with 360 degree maneuver.

    Remove the raw materials by the scraper to the yard at the bottom of the discharge port, the discharge belt conveyor by a trench away. (3) Round yard generally use 3 120 degree operating method, that is 1/3 volume of the ongoing round yard stockyard operations; 1/3 volume of the ongoing reclaiming operation; 1/3 of the heap as to reserve material, There are actually 2/3 of the stockpile as a reclaimer stockpile (but not impact crusher). Therefore, the capacity of 2/3 of the circular yard effective capacity. Generally the same reserves the round yard can be 30% smaller footprint than rectangular yard. (4) changes in the the circular yard divided into three (3 1200) method of operation, the eradication of the material in the heap of the transition zone and the end of the cone, round yard windrow formation of a ring never disconnected. The round yard continuous operates to the plan view of FIG.

    (5) vertical and tilt layer combined stacker herringbone. (6) pre-homogenizing effect of continuous operation method in the the round yard of application, further improve and expand the effective volume of the utilization of the yard, to further promote the application of the round yard. Other yards applications. in the cement industry is small, for example: Lying on library-style yard, built crane library type, with the bridge Paternosters viscous materials reclaimer; yard with a slit-shaped warehouse at the bottom of the impeller reclaimer reclaimer, and so on.
