LG Series Dry Pelletizer

Short Description:

Operating Principle: Charge the prepared powder with certain amount of crystal water in the hopper. The powder is propelled to the upper part of the two extrusion wheels as conveyed and compressed (the density of the doubles and redoubles) by the feeding screw. At this point, the powder is under such a condition as being pressed from five directions. with the turning of extrusion rollers, the powder is delivered to the space between the two extrusion rollers for intensive extrusion and turn i...

Operating Principle:
Charge the prepared powder with certain amount of crystal water in the hopper. The powder is propelled to the upper part of the two extrusion wheels as conveyed and compressed (the density of the doubles and redoubles) by the feeding screw. At this point, the powder is under such a condition as being pressed from five directions. with the turning of extrusion rollers, the powder is delivered to the space between the two extrusion rollers for intensive extrusion and turn into hard bars, which are crushed and granulated into ideal grains by the granulating system. The entire process automatically proceeds.

1. Main Uses:
It is suitable for such occasions where raw material uses its self-contained crystal water for direct dry extrusion and grain forming in pharmaceutical, chemical and food productions.

2.Main Characteristics:
1)Heat proceeding from extrusion is cooled by the cooling water producer.
2)Surface of extruding roller is specially designed and processed to avoid caking.
3)The side seal structure and the reasonable scraper bar structure may effectively eliminate the phenomenon of fine powder at the side of running roller.
4)The structure of crushing system plus two pairs of roller granulating mechanisms employed in the extrusion, crushing and granulating system is a creation in the country which coordinates the feeding and discharging of materials and produces ideals grains. The system is enclosed in a sealed stainless steel housing to avoid flying dust in the operation room.
5)For the profiled non-equal-distance screw stem,nylon screw stem or stainless steel screw stem is provided depending on different material requirements.
6)Oil lubrication is used for bearings of principal axes instead of the commonly used grease lubrication and thus has enabled the machine to be filled with oil with out the necessity for assembly and disassembly.
7)The reasonable housing structure is convenient for a ssembly and disassembly as well as internal cleaning,which is in conformity with GMP verification requirements.
