Vibrating grizzly feeder is a kind of linear direction feeding equipment. The vibrating grizzly feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc .The Vibrating Feeder has been used to transfer the large size materials and granular materials from hopper to receiving device uniformly, periodically and continuously in the production flow and to feed materials into the crusher continuously and uniformly also to screen the materials in the sandstone production line.
Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed. When installation, the two gears must be jogged according to the sign. Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, The materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, avoiding the further crushing, so screening purpose can be reached.Vibrating feeder can be used in these areas such as metallurgical industry, coal mining industry, mining-selecting, building, chemical and grinding industry, etc.
Vibrating feeder features
Vibrating feeder is used to feed raw materials into the primary crusher continuously. Vibrating feeder is widely used in stone quarrying, aggregate production, sand making, ore beneficiation, coal and cement industry to feed limestone, granite rock, basalt rock, river stone, iron ore, copper ore, feldspar, gold ore, bauxite ore etc. to primary crusher. According to the process capacity of the primary crushing machine and the whole crushing plant, the clients can adjust the feeding capacity flexible
Vibrating Feeder with Unbalanced Motor is available in medium and heavy duty models for conveying bulk materials. Electro mechanical Vibrating Feeder is used where material is to be fed either continuously or in batches. Offering uninterrupted operation each feeder utilizes the forces set up by two synchronized, counter-rotating, heavy-duty, unbalanced Vibratory Motors, which are firmly fixed to the Feeder trough, in a specific angle to the feeding level. Feeders with unbalanced drives, vibrate freely on a support spring which is insulated against vibration transmission to base frame. This results in a straight line, push-pull, -linear, oscillating motion. The fact that the motors are synchronized and in balance with one another, eliminate the isolation problems normally associated with simple brute force single eccentric drives systems.
Electromechanical Vibrating Feeders are designed to convey product by creating a linear straight line motion. Two counter-rotating WAGWELL motors provide the linear (push-pull) action required. As the Unbalanced motors counter-rotate, the side forces cancel out and the linear forces are combined. With the motors properly attached and located on a rigid trough suitable for the forces being exerted, and also suspended on isolation springs, the conveyance action is quiet and positive. The synchronized motors provide a semi-balanced design which eliminates the uncontrolled bouncing at shut down. Final motors selected can be either 1800, 1200 or 900 RPM, depending upon amplitude required. Final motor horsepower selected is a function of trough weight and TPH capacity required. All motors are continuous duty rated at maximum force.
It is been widely used in the food, mining, cement, refractory, iron ore, coal feeding, feed, chemical and the pharmaceutical industries,etc.
Vibration feeder simple structure, convenient operation , power consumption is small; Can adjust evenly to ore amount; So has been widely used. Electromagnetic vibrating feeder is in the material from the bunker or other storage device or even the supply of quantitative is expected in the equipment, is a necessary equipment for automation flow operation to open type and closing two points. Generally for loose material. It is used for the pharmaceutical, glass, food and chemical processing, steel, plastics, rubber and fertilizer industries. Additionally, electromagnetic vibrating feeders are specially applied for industries that involve non-stop processes. So that it can handle slightly wet, heated, dusty, lumpy and abrasive materials, electromagnetic vibrating feeders are applied in batching, weighing, packaging, blending, sprinkling, proportioning and storage.
A vibratory feeder is a device that uses vibration to "feed" material to a process or machine. Vibratory feeders use both vibration and gravity to move material. Gravity is used to determine the direction, either down, or down and to a side, and then vibration is used to move the material. The material is almost always a dry material that unlike a liquid, may not move down an incline without some assistance from the vibration effect. The vibratory feeder comes in many shapes and sizes but all uses the same principle, which is to feed bulk material in at the top in an uncontrolled fashion and take material out at the bottom at a controlled and steady rate.
Our experience and longevity in the market have resulted in a variety of deck models.
