Auger Extruder

The processed raw materials are sent to the feeding section of the upper mixing part through a conveyor, and in the feeding section, appropriate amount of water can be added to the raw materials to adjust the briquetting moisture.

With the rotation of the stirring shaft, the mixing knife continuously mixes and homogenizes the raw materials, and continuously pushes the raw materials to the sealing extrusion section. In the sealing extrusion section, there are a pair of spiral sealing reamers that rotate in opposite directions continuously. Thus sent raw materials are extruded and kneaded, and the material is finally extruded into dense sticks through the material sealing grate plate and continuously squeezed into the vacuum box, and the dense sticks are formed on the population of the vacuum box Vacuum mud seal to ensure the required vacuum degree in the vacuum box.

When the raw material falls from the vacuum box into the lower receiving box, the air in the vacuum box and the stick is sucked out by the vacuum pump through the vacuum suction pipe on the top of the vacuum box to realize the vacuum treatment. The material then falling into the lower receiving box and forcibly pressed into the lower extrusion reamer through a pair of pressing plates with opposite rotation directions. With the rotation of the reamer shaft and the diameter and pitch of the reamer itself, the structural characteristics make the material gradually compacted during the forward conveying process, and finally extruded into a briquette or brick with the desired shape and section through the machine head and the forming outlet.

The compressed air provides pressure air source for the upper and lower axial pneumatic clutches, and the automatic clutch of the pneumatic clutches is controlled by the electromagnetic cut-off valve, so that the upper and lower stages can be started and stopped at any time during the operation of the equipment.

1. The transmission design of the upper and lower stages is separated, and the upper and lower stages of the equipment are installed in a T shape (the extruder can be installed on the left or right according to the needs), which is convenient for maintenance and provides options for equipment layout in future technical transformation.
2. The axial pneumatic clutch is used to make the structure of the whole machine more compact and beautiful, and it can realize remote operation and control of the whole machine equipment.
3. The sieve plate sealing scheme is adopted in the upper sealing section, which can improve the adaptability of the equipment to raw materials.
4. The lower-stage extrusion reamer adopts the design scheme of variable diameter and variable pitch, which provides a guarantee for improving extrusion efficiency and extrusion pressure.
5. The working surface of the extrusion reamer and sealing reamer adopts the special technology of wear-resistant surfacing welding; the mixing knife adopts the insert structure and high wear-resistant alloy material, and the service life is reliably guaranteed.
6. The whole machine is equipped with comprehensive and reliable dynamic and static sealing devices and seals.
7. The spindle structure is uniquely designed to fundamentally improve the reliability and service life of the whole machine.
8. The main body is all steel structure, which improves the strength and service life of the equipment.
9. The lower reducer is a planetary gear reducer with small size, high transmission efficiency, compact structure and high reliability.
10. Due to the large transmission power of the lower reducer, the temperature of the lubricating oil in the reducer will rise after a long period of continuous operation. A circulating cooling device with automatic operation is installed. The starting point temperature of the circulating cooling device has been set at 50C when the equipment leaves the factory. The oil is pumped out and cooled before being pumped into the reducer. The adjustment and setting of the operating starting point temperature of the circulating cooling device is carried out on the operation control panel of the equipment.
11. The special structure design ensures the low speed and high vacuum of the equipment operation.
