The vibrating feeder is mainly used for continuous and uniform feeding before the coarse crusher, and at the same time, the fine material can be sieved to increase the capacity of the crusher. The machine adopts the structural characteristics of the double eccentric shaft vibration exciter to ensure that the equipment can withstand the impact of falling of large materials and has a large feeding capacity. In the production process, the block and granular materials can be uniformly, regularly and continuously sent from the storage bin to the receiving device, thereby preventing the receiving device from colliding due to uneven feeding, and prolonging the device. Service life. The feeder can be divided into a steel plate structure and a purlin structure. The feeder of the steel plate structure is mostly used in the sand and gravel production line, and the materials are all uniformly fed into the crushing equipment; the feeder of the purlin structure can roughly screen the materials. It makes the system more economical and reasonable in preparation, and has become an indispensable equipment in crushing and screening. Therefore, the machine is widely used in crushing and screening combined equipment in metallurgy, coal mining, mineral processing, building materials, chemical industry, abrasives and other industries.
Features and advantages
1. Linear motion trajectory with stable vibration;
2, special grid design to prevent material blockage;
3. The gap of the grid is adjustable. The series of vibrating feeders are reliable in operation, low in noise, low in energy consumption, no punching phenomenon, long service life, convenient maintenance, light weight, small size, convenient adjustment and installation of equipment, and good comprehensive performance. Prevent dust pollution when using a closed structure.
Working principle The vibrating feeder is composed of a feeding trough body, a vibration exciter, a spring bearing, a transmission device and the like. The vibration source of the tank vibration feeding is the vibration exciter. The vibration exciter is composed of two eccentric shafts (main and passive) and a gear pair. The motor drives the driving shaft through the V-belt, and the gear on the driving shaft meshes with the passive shaft. Rotating, the main and passive shafts rotate in the opposite direction at the same time, and the tank body vibrates, so that the material continuously flows continuously to achieve the purpose of conveying materials.
