Introduction Mesh-vibrating sifter has similar structure and function with the Hi-Cline Screener in Rotex, and it is suitable for material’s classification,especially for the loose material and fine particles. Mesh-vibrating sieve is designed and manufactured autonomously by absorbing the American’s advanced technology experience, its vibrating source is electromagnetic high frequency vibrating, which makes screen and screen frame oscillating, so as to realize the material classification. The amplitude of the sieve machine is adjustable. Working principle 1.the deck vibration frequency is 50Hz,amplitude is 1-2mm,it has very high vibration intensity, it can reach 8-10 times gravitational acceleration, which is 2-3 times to the ordinary sifter vibration intensity. Vibrators fixed on the screen box, the vibrator flexible system is balanced with the exciting reaction force on the screen box, so the screen box is not moving. The exciting force drives the vibration system shake the deck. The machine is supported by rubber damping spring, dynamic load is very tiny,and need not special foundation, and it can be random installed. 2.The deck consists of three different layers of the flexible screen, the bottomed mesh is made of rope-core polyurethane mesh, trawl formed by hook plate on both ends tight, and contacted with exciting device directly. Composite mesh is paved on tow-net, and it comprised of two-layer bonded stainless steel mesh. The top of composite mesh has contacted the material directly, its bottom mesh size is much more bigger than the top mesh, the bottom mesh contacts the tow-net, thus reducing the working mesh wear. The working mesh aperture ratio is very high, and it has certain rigidity, and it is easy to install, then improving the service life of the screen.

Linear vibrating screen adopts double vibrating motors as power source, with the specific working mode of these two motors make the materials be thrown up on the sieve and go forward in a straight line.

Introduction The main function is to provide accurate separation of materials without product deterioration, thereby resulting greater product yields at higher production rates. This screening equipment consists of Supporting rack, screen frame, the cleaning ball, side plate, screen box, deck, screen assembly, etc. The unique gyratory motion of the near horizontal screen surface and the available screen mesh cleaning system secure the M&Y gyratory vibrating screen quality as a high capacity product that efficiently developed for materials screening purposes. Functional principle  M&Y gyratory vibrating screen puts the distribution of material device and screening plant together as it passes along the screen surface. It begins with a horizontal circular motion at the feed end, gradually changes to changes to elliptical motion at the center, and finally to a straight-line motion at the discharge end, keeping the material in constant contact with the screen surface without deterioration. Advantages No vertical vibration, longer life span of screen deck. All components are easily accessible and removable for ease of teardown and cleaning. Due to adopting the principle of plane rotary, thus improving the effective utilization rate of screen surface and eventually improving the screening efficiency.

Introduction Tumbler sieve is designed to meet the high output and precision screening of manufacturers and special design of an efficient screening machine. The simplest screening is a binocular fixation and hands screening, swinging screening machine is the simulation of this movement. At present, it is the most effective simulated artificial sieving movement effective principle. It meets all the fine and ultrafine particulate materials, especially for hard process materials.  Functional principle  The residence time of each product can be adjusted by the radial direction and the tangential angle of the swinging screen. Then, established the level and throwing three-dimensional tumbling motion. From the center to the outer edge in the sieve surface is uniformly dispersed, to in a spiral motion to the axial propagation. Thus fine particles complete the whole screening process. Horizontal and vertical acceleration with the movement of the material increased, and close to the aperture size of particles subsequently successfully separated, larger particles were transported to the exit, the outlet is controlled by an adjustable guide device, which is another factor that controls the retention time of the material. The process is repeated among each layer of screen. Advantages Greatly improving the screening efficiency Shorten screening time

Introduction Under some special working conditions, such as space limitation or higher requirements of replacing the screen, MPG series gyratory vibrating screen is an ideal choice. It has the similar functional principle with gyratory vibrating screen, while, the MPG gyratory screen has a unique and economic design which not only reduce the downtime but also increase the productivity. Each screen divides into many screen deck, and every deck is very light, one person can complete screen replacement. Due to the decrease of the screen size, it needs smaller space when the screen is replaced. There are side-opening doors replacing the screen on both sides, it does not affect the upstream and downstream equipment when changing screens. Functional principle  MPG series gyratory vibrating screen puts the distribution of material device and screening plant together as it passes along the screen surface. It begins with a horizontal circular motion at the feed end, gradually changes to changes to elliptical motion at the center, and finally to a straight-line motion at the discharge end, keeping the material in constant contact with the screen surface without deterioration. Advantages Less space needed, saving labor costs. Replacing screen’s time is shorter, thereby improving screening efficiency. Side door design reduces workload furthest.

Introduction Linear vibrating sifter is used to separate materials into various particle sizes for further processing.Basically, professional large capacity mining linear vibrating screen manufacture consists of the screen box, supporting device, driving unit,vibration isolation and etc. It has two operational driving modes: dual-vibration mode (light duty) and dual-vibration exciter mode(heavy duty). Working Principle The vibrating source is also from vibrating motor. There are two motors to be fixed on the both side of screening box(or under the screening box) to corotate on the contrary direction. In the process of rotating, when two motors synchronous reversely rotate, the eccentric blocks of motor will emerge a kind of centrifugal force, which can be transmitted to the screening box and make the machine run by linear direction. Then the material on the mesh will be vibrated forward and screened. There is an angle of inclination two motor axis's relative to screen deck, under the influence of resultant force of exciter force and materials self weight, materials are threw up to make saltatory and linear movement forward on the screen deck in order to screen and grade the materials. By choosing the suitable mesh, the screening target is realized.   Features High productivity Tightness, very little dust spilling, also can be enclosed or can be connected with duct collector.
