Feeder breaker Variable frequency motor drives the driving wheel through the transmission drive device, the driving wheel through the sprocket and the ring chain mesh drive the driven wheel rotation; At the same time, the conveyor scraper connected with the ring chain is driven to move horizontally in the conveyor box, and the conveyor scraper drags the materials in the conveyor box for material transportation at the same time. When the horizontal movement of the conveyor scraper and its material pass through the rotating crusher roller in the crushing box, because the large material cannot pass through the specific space between the crushing roller and the conveyor scraper, the large material will be knocked, squeezed and stretched by the rotating tooth roller until it is broken, and the small material less than the discharge particle size requirements can pass through the crushing roller without breaking. The final broken material is discharged through the discharge port of the crushing device.
By adjusting the frequency of the inverter and changing the speed of the variable frequency motor, the running speed of the conveyor scraper can be changed, and the processing capacity of the whole equipment can be adjusted to a certain extent. By adjusting the center height of the crushing tooth roller, the crushing and discharging particle size can be adjusted to meet different customer needs.
Main structure
The scraper conveyor of feeder breaker is composed of transmission device, conveying box, conveying chain, frame tail guide device, etc. The crushing part is mainly composed of crushing drive, crushing tooth roller and crushing box. Pre-screening by dynamic screening and static screening two ways, according to different working conditions to configure.
The reducer adopts a large speed ratio, high torque planetary reducer, torsion arm suspension support, no foundation support. Choose well-known brands at home and abroad. The reducer has good sealing and does not leak oil. The reducer is easy to replace and disassemble, and the self-positioning card block is designed between the gear coupling box, which can realize the rapid installation of the center. The reducer has an intuitive oil level indicating device, and has a suitable fan cooling system, oil temperature detection device and input shaft bearing temperature detection device, and enters the centralized control. Selection of well-known brands at home and abroad, frequency conversion motor selection of high-efficiency energy-saving motor, this motor low energy consumption, high mechanical power, with good transmission efficiency and energy-saving effect, generally suitable for heavy duty large conveying capacity equipment, in line with the latest national energy-saving standards products, insulation level: "grade, protection level: P55, frequency 0~50Hz, stator winding adopts high quality copper core, large temperature rise margin, long life, cooling mode is C416(independent air cooling), motor is continuous working system S. Bearing temperature measurement and winding temperature measurement, and can be connected to the plate feeder operation control system. Independent temperature measurement junction box is set, and the motor is set with anti-condensation heater.
Conveyor chain
Feeder breaker conveyor chain is made of high strength mining ring chain through the rectangular tooth connection ring and the conveyor scraper in series. After hardening treatment, the resistance and impact resistance of the ring connection are improved, with good wear resistance and long service life. The normal service life is not less than 3 years.
Conveyor box
The conveying box is composed of a number of small conveying box combinations lined up to form the conveying box, the main function is to connect the head and the tail and carry the conveying chain to slide in it to transport materials. Welded by Q345 steel plate, strong structure; Shot blasting is carried out before blanking, stress relief is carried out after welding is completed, and then shot blasting is carried out, and finally spray painting is carried out. Ensure the quality and appearance of the body. The inner liner is made of wear-resistant plate and connected by bolts, making it easy to replace.
Sprocket wheel
The drive sprocket and tension wheel are forged from alloy, and the working surface is quenched after normalizing, and the hardness is HRC48-56.
Tail guide
The tail guide device is composed of a guide spindle equipped with two guide wheels installed on the tail of the frame through two sliding bearing seats. Through hydraulic adjustment, convenient and fast.
Feeder breaker is a kind of crushing and conveying equipment specially for the production of leaky mine. It has the advantages of large processing capacity, low investment cost and low operating cost.
