Feeder, also known as feeder, is mainly used in crushing and screening combined equipment in metallurgy, coal mine, mineral processing, building materials, chemical industry, abrasives and other industries. It is an indispensable and important equipment in the whole production line when it is fed to the receiving device.
At present, common feeders include screw feeders, vibrating feeders, etc., and vibrating feeders are the mainstream models of application. The vibrating feeder is composed of a vibrating frame, a vibrating body, a vibrating motor, an exciter, and a spring (the spring is divided into an excitation spring and a support spring).
In terms of working principle, the vibrating feeder uses the rotation of the eccentric block in the vibrator to generate centrifugal force, so that the movable parts such as the screen box and the vibrator are forced to move in a continuous circular or approximately circular motion. The belt drives the drive shaft, and then the gear on the drive shaft meshes with the passive shaft to rotate, and the main and passive shafts rotate in opposite directions at the same time, so that the tank body vibrates, so that the material flows continuously and achieves the purpose of conveying the material.
The vibrating feeder is located at the beginning of the production line. The upstream production situation will directly affect the downstream. The most feared problem in the production process is the slow feeding speed of the feeder. There are various reasons for the slow feeding speed. Generally, there are external reasons for the insufficient placement angle of the organism, but more are the reasons for the vibrating feeder itself, such as insufficient vibration intensity.
HSF vibrating feeder
HSF series bar vibrating feeder is a feeder developed by Bellian Group on the basis of years of accumulation and technological innovation. It avoids common problems during the research and development process, integrates the latest technology and effectively solves the problem of feeding Slow feeding speed, poor machine stability and other problems.
Compact structure and high impact resistance are critical. The feeder often has to carry materials such as stone and building materials. These materials are irregular in shape, high in hardness and heavy in weight, which will inevitably cause collision and impact on the body.
The main components of the HSF series bar vibrating feeder, such as the box side plate, the reinforcing plate, the frame beam, etc., are all made of Q355 high-strength plate for overall CNC cutting, and the contact surface is made of AR400 wear-resistant plate. When assembling, all bolts are tightened with a special torque wrench according to the standard requirements to prevent the bolts from loosening. When welding, a dedicated welding engineer is responsible for the equipment welding to minimize welding stress. From material selection to process, strict requirements in all aspects make the body strength of the vibrating screen optimal.
The body is sturdy and has strong impact resistance, so it can apply high-intensity vibration. If the body is not strong enough and high-intensity vibration is applied, problems such as cracking of the side plate, bottom plate, and the body falling apart will occur. It is the high-strength body that greatly enhances the impact resistance of the equipment. The vibration strength of the HSF feeder can be as high as 4.5G, the maximum feeding particle size in production can reach 1500 mm, and the maximum feeding volume can reach 2000. ton/hour, whether in the production of stone, building materials, or metallurgical mines, the equipment can fully meet the demand.
In addition, HSF feeders perform well in other ways. In terms of lubrication, the HSF feeder has an excellent thin oil lubrication system, which can effectively lubricate all key parts of the equipment, making the maintenance cycle of the thin oil lubrication system up to 1200-1500 hours. Each shaft is independently lubricated, making the entire production flow more smoothly.
HSF feeder is an advanced equipment in the industry based on the summarization of many on-site production experiences and the blessing of the latest cutting-edge technology.
