Product introduction

A belt feeder is an indispensable equipment in clean coal production line. It is widely used in metallurgy, chemical industry, construction and other large-scale high-yield and high-efficiency industries, especially suitable for bulk material conveying system. It is a new type of continuous feeding equipment. In general, the delivery capacity of the equipment can reach thousands of tons per hour, which is incomparable to ordinary models.
 
 Belt feeder

Product features

1. The equipment is stable and reliable, with small power and low energy consumption, but the feed rate is relatively large, with an average of several thousand tons per hour, which is efficient and stable, and has good economic performance.
2. The noise generated by the operation of belt a feeder is relatively small, the materials are fed in the sealing device, and the investment cost is low. It is an energy-saving and environmental protection equipment.
3. When adjusting the speed of the equipment, manual or electrical stepless speed regulation can be adopted, and the feeding amount and running speed can be adjusted according to different requirements of customers, so as to fully realize remote control operation.
4. The equipment is a kind of universal equipment with more than 90% of the common parts. It is easy to install and maintain, and the wear of each accessory is small and the maintenance quantity is small.
5. The bottom of the silo is equipped with several groups of buffer idlers, which can enhance the impact resistance, effectively protect the armour belt from abrasion and have a long service life.
6. There is an arch breaking device inside, which can overcome the air blocking and arching phenomenon in the silo, and ensure the smooth flow of materials. It can also replace other types of feeders in use.

Product characteristics
 
1. Because the sealing device is used between the material guide groove and the belt, there is almost no gap between the two materials, which plays a role of sealing and protecting the materials and the environment.
2. If you want to change the feeding rate of the equipment, you can change the speed of the output shaft by adjusting the speed regulating hand wheel of the reducer of the equipment, so as to change the feeding amount.
3. If you want to change the running speed of the a-belt, you can change it by adjusting the frequency of the frequency converter of the equipment.
4. Changing the size of the feed inlet can be realized by the opening of the gate.
5. During the operation of belt a feeder, the main load of the system is supported by rolling bearings, with small running resistance, small driving power required by the equipment, and long service life of all parts of the system.
 
 Common faults of a-belt coal feeder

working principle

      When feeding materials, the materials enter from the previous process of the equipment, and enter the guide trough through the connecting section, and the feeding port falls on the a-belt. The friction force between the material and the a-belt is used to move forward, forming an angular static accumulation at the discharge port. At the same time, the driving drum starts to rotate under the driving device, and drives the belt a to rotate together. The belt drives the materials on the belt a Push it to the discharge port and turn back, and the material will be discharged from the outlet continuously. With the inertia, it will fall into the next equipment to complete the feeding process.
 
 Hydraulic gate of belt feeder
 
The sealing device provides a seal for the material leaking out from the gap between the guide groove and the belt. During the return journey, the unshipped material adhered to the a-belt is continuously dropped on the lower guard plate due to the influence of gravity and vibration, and then is taken back to the discharge port by the scraping plate protruding on the a-belt.

product mix

According to the principle of variable speed belt conveyor, the speed can be adjusted by variable speed belt conveyor. The connecting section is installed at the mouth of the bin, under which a guide groove is installed, and a feeding device is installed under the guide groove.
      A belt feeder is composed of connecting section, guide groove, gate mechanism, driving motor, drive drum, direction changing drum, annular belt and a-belt. The annular belt is wrapped by belt a, and the annular belt is mainly used for traction. Belt A is the main part of carrying materials. In this way, the belt a can effectively protect the annular belt from being scratched and torn by hard coal and sundries.
The driving device is driven by the stepless speed reducer through chain transmission. The driving device and the feeding device a are both installed on the bracket and can be adjusted. In order to reduce friction, the cross section of the feeder guide groove is inverted trapezoid. On the guide groove, a gate mechanism and a driving hand wheel are installed to open and close the outlet during maintenance.

Instructions for use

1. Regular maintenance and overhaul is an important means to extend the service life of the machine and ensure normal operation, and users should pay attention to it. For lubrication, pay attention to the following points:
(1) The machine adopts splash lubrication of thin oil. The lubricating oil should be determined according to the place of use and air temperature. Gear oil is generally used;
(2) It should be ensured that the thin oil level in the vibration exciter is higher than the height of the oil level (filled through the joint elbow). It must be replaced every 3-6 months. Clean gasoline or kerosene should be used to clean the oil tank, bearing raceway and gear surface.
