Introduction YK series circular vibrating sifter is a kind of new and highly effective vibrating screen that does circular vibrations and has multiple layers. Circular vibrating screen adopts cylinder postures eccentric block to produce strong exciting force. Its main body is connected by high strength screw bolts. A circular, elliptical vibration motion is created in order to sieve the materials efficiently. It is composed of screen box, screen mesh cloth, suspension (or support) device, under-frame and motor. Working Principle When circular vibrating screen on operation, first the materials will feed on the screen mesh, and the materials will separated uniformly on screen mesh plates. The rolling bearing of the screen will stressed by highly mostly shock-type loads. And more, the screen bearing ,while rotating about their own axis, going a way of circular ,elliptical or linear vibrating motion .This results in high radial accelerations which additionally stress the bearings , and especially the cages considerably. The operating speeds are usually in a very high condition. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignment between the bearing locations and considerable shaft deflections have to be accommodated. Features Ring groove rivet connections, advanced structure, strong and durable. To connect sieve and the sieve beams by using high strength bolts, simple structure and convenient maintenance. To use eccentric block as the excitation power, strong power, low power consumption and noise. Small amplitude, high frequency, large angle structure, high screen efficiency, and high processing capacity. Vibrator uses a large clearance bearings, thin oil lubrication, low noise, long service life. universal parts and easy maintenance. Application Circular Vibrating sifter is widely used in mining, power stations, water conservancy projects, building industry, light and chemical industry, for coal dressing as well as in metallurgy. Generally, these models are built to specifically classify large, middle and small materials efficiently.

Circular vibrating screen is a new type of vibrating screen with circular vibration, multi-layer number and high efficiency. The circular vibrating screen adopts cylindrical eccentric shaft exciter and eccentric block to adjust the amplitude. The material screen has long flow line and many screening specifications. It has the characteristics of reliable structure, strong exciting force, high screening efficiency, low vibration noise, durability, convenient maintenance and safe use. The vibrating screen is widely used in the product classification of mining, building materials, transportation, energy, chemical industry and other industries. Sports introduction Vibrating screen is divided into resonance screen and inertia vibrating screen according to whether the vibration frequency is close to or far away from the resonance frequency. Resonance screen once rose, received universal attention and developed rapidly; However, in production practice, the disadvantages of complex structure, difficult adjustment and many faults are exposed. The inertial vibrating screen is widely used because of its simple structure, reliable operation and easy maintenance. The inertial vibrating screen is driven by the inertial vibrator with eccentric block fixed in the middle to vibrate the screen box. Inertia vibrating screen can be divided into single shaft vibrating screen and double shaft vibrating screen according to the form of vibrator.

It is widely used for grading and screening materials in the following fields: mines, quarries, aggregate, high-way construction, building materials, chemical industry, and metallurgy and so on. Working Principle: Vibrating screen uses electric exciter as vibrating source; the material will be thrown around the screen, at the same time doing forward sports, in order to achieve the screening purpose. Material from the feeder evenly enters into the machine's feeding inlet, with multilayer sieves to produce various of products and unqualified products on the screen or under the screen, then discharging from the outlet respectively. It can be used in the automatic production line.

Combining high technology and innovative engineering with its experience, , operates and delivers crushing and screening plants with this coordination. Quality and trust is the most important priority in every material used. series sieves are used to separate the aggregate into different sized classes. It is manufactured as 1, 2, 3 or 4 layers. A separate engine, belt-pulley system, eccentric shaft mounted on the sieve body with special bearings, are driven by an eccentric weight at each end of the shaft, and they separate the aggregate according to its dimensions by making circular vibrations. completes the required spare parts and service requests as soon as possible.

Introduction YA series circular vibrating sifter is a multi-layer, high-efficient vibrating screen machine, with the applications of classification, separation, grading, according to material particle size. It is basically a sifting machine that works in circular motion to classify any sizes of bulk materials, such as coal, minerals, stone, and coke, etc. Separating machine consists of screen deck, screen box, vibrating motor, eccentric block, rubber spring, and coupling-adopt motor with vibration exciter that work together to efficiently classify and separate the materials according to any requirement size. Working Principle Circular Vibrating Sifter using indirect excitation of the screen mesh. The entire screen frame is driven by unbalance masses, which produce a circular vibrating motion. It used eccentric block to produce strong exciting force. The directionless vibrations of the circular vibrating system have a steep launch angle and the screen area must be further tilted in order to achieve a suitable transport speed. Drive and Mounting of Circular Vibrating Screen Drive is by electric motor and cardan shaft to the main drive shaft equipped with a single unbalance weight where required additional v-belt can be provided. The drive shaft is mounted on heavy duty roller bearing sets, lubricated with grease or oil. Like the linear vibratory screens, circular vibrating screens are mounted on reinforced rubber springs to prove the same benefits in performance and longer lifespan. Features Advanced structure and easy maintenance; High amplitude and large angle of inclination; High screening efficiency, large processing capacity, multiple layers (1-5); Long service life, low power consumption and low noise; High sifting efficiency; Adoption of punching sieve or steel made screening mesh in order to prevent blockage; Sift body connected by using high strength screw bolts; Adopts spring steel woven mesh or perforated sieve-plate, which is helps to prolong the service life and prevent blockage; Rubber vibration spring is used to reduce noise pollution and provide smooth vibration operation. Application YA series vibrating sifter is Widely used in Chemical, coal dressing, mineral ore dressing, building material, hydro-power, light, construction industries, etc. Generally, these models are built to specifically classify large, middle and small materials efficiently.

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.
