Vibrating feeder, also known as vibrating feeder, is specially designed for uniformly conveying large pieces of material in front of the coarse crusher. The vibrating feeder adopts the structural characteristics of double eccentric shaft vibration exciter to ensure that the equipment can withstand the impact of falling large pieces of material and has a large feeding capacity. In the production process, lump and granular materials can be uniformly, regularly and continuously fed from the storage bin to the crusher. In the sand and gravel production line, the crushing machinery can be continuously and uniformly fed, and the materials can be coarsened. Screening to prevent the crusher from crashing due to uneven feeding and prolong the service life of the equipment. It is widely used in crushing and screening combined equipment in metallurgy, coal mine, mineral processing, building materials, chemical industry, abrasives and other industries.
working principle
The vibrating feeder uses the rotation of the eccentric mass in the vibrator to generate centrifugal force, so that the movable parts such as the screen box and the vibrator make forced continuous circular or approximate circular motion. The vibrating feeder is composed of a feeding trough, a vibration exciter, a spring support, and a transmission device. The vibration source of the trough vibrating feed is a vibration exciter, which is composed of two eccentric shafts (active and passive) and a gear pair. The motor drives the active shaft through a V-belt, and the gear on the active shaft meshes with the passive shaft When rotating, the active and passive shafts rotate in opposite directions at the same time, so that the tank vibrates, so that the materials flow continuously, and the purpose of conveying materials is achieved. According to its structure and purpose, the vibrating feeder can be divided into: ZSW series vibrating feeder, DHS series vibrating feeder, GZG series vibrating feeder. Of course, different manufacturers have different naming methods, and differences in models are normal.
ZSW series vibrating feeder is designed based on the principle that the shaft eccentricity generates exciting force. It is mainly used for continuous and uniform feeding before the coarse crusher. At the same time, it can pre-screen the fine material, making the crusher more efficient and widely used. Used in metallurgy, mining, chemical, coal, building materials and other industries. It has stable vibration, reliable work and long service life; the structure of the discharge end is diverse, which can be installed with screen bars, flat plates, and plate drilling, etc. The gap between the screen bars is adjustable; the use of thin oil lubrication can make the product lubrication, heat dissipation, and prolong life Etc., optional variable-frequency speed-regulating motor, easy to control the feeding amount, without the need for frequent motor start.
The DHS series vibrating feeder is a high-energy-efficiency heavy-duty feeder produced by our company introducing foreign technology. This series of feeders are designed with a more sturdy reinforced frame, which can meet the harsh and complex working conditions and ensure that The equipment is highly reliable. It has a solid heavy-duty tank structure, reliable strength, impact resistance, large processing capacity, and a wider range of applications; zigzag grate cascade arrangement, with self-cleaning function, not easy to block materials, and easy to replace and adjust the gap; large amplitude, Large feeding capacity, large effective area of pre-screening, good pre-screening performance; adopting vibration absorbing technology to avoid lateral shaking caused by resonance when starting and stopping; optional variable frequency speed regulating motor, easy to control the feeding amount and other characteristics.
GZG series vibrating feeder is a trough feeder with a vibrating motor as the vibration source. It is mainly used to uniformly, continuously and quantitatively transport loose blocks, particles and powders from the storage bin to the relevant receiving equipment It is widely used in metallurgy, mining, chemical, coal, building materials and other industries. It is an auxiliary equipment in the crushing and processing of various minerals and rocks. It is a simple, practical and efficient storage and feeding equipment. It has simple structure, convenient maintenance, low noise, easy installation, stable work, fast start, stable stop; the vibration motor is used as the excitation source, the material is in parabolic motion, the feed trough wears little, and the service life is increased; it can be changed instantly Start the material flow to improve the accuracy of quantitative feeding; the tank body is formed by integral bending, which is light in weight and strong in strength.
These three types of feeders have their own outstanding advantages, but what production line is each suitable for? GZG series vibrating feeder (suspended motor vibrating feeder) is often used in medium and fine crushing crushers. Its advantage is stable feeding, and the feeding amount can be selected according to the size of the crusher; DHS series heavy-duty vibrating feeder It can be used in harsh and complex working conditions, and is mostly used for large-scale mine coarse-breaking feeding; ZSW series vibrating feeders are mostly used in metallurgy, mining, chemical, coal, building materials and other industries, and can also be customized according to customer needs. Weir plates, liners, and bottom plate pre-screening parts can also be equipped with blind plates or expanded metal meshes, which are suitable for different working conditions.
