900 Class Sugar Mill Chains
900 Series Pintle Chains, sometimes referred to as "sugar mill" or "intermediate carrier chain" is used extensively in sugar mills. Multiple strands of 900 Pintle Chain, available with one or two holes per link, can be fitted with overlapping beaded carrier slats to form a continuous apron conveyor for intermediate carrier service.
The pin holes at the closed end of the 900 Class link are provided with smooth bushings which are press-fitted into the links and keyed into place. The bushings are renewable and can be driven out and replaced when they become worn. 900 Class Pintle Chain is designed with dual barrels, one on each side of the open end of the links, to accommodate double sprockets.
The purpose of this driving method is to eliminate the possibility of material build-up in the sprocket contact area, which often causes the chain to jump the sprocket. Heavy ribs rigidly reinforce these driving barrels.
Our 900 Class chain links, with tensile strength from 22,500 to 32,500 pounds, are available with large sliding surfaces to reduce chain wear and prolong chain life. Broad wearing surfaces and heavy cross sections team up to provide a substantial link which is made according to manufacturer's standards and can perfectly replace links made by other manufacturers.
Brutaloy sprockets for 900 Class Pintle Chain are readily available in 3.170 inches. 900 Class Pintle Chain should only be allowed to travel in one direction; links should always run in the direction of their closed narrow end.
Available in cottered construction only, 900 Class Chain is assembled with T-headed pins which are locked into place by two lugs cast on the ends of the driving barrels to prevent pin rotation. Pin rotation during operation would result in wear on the inside of the bushing. Both the head of the pin and the cottered end of the pin are protected by cast lugs on the barrel end of the links.
Material ：900 Class Pintle Chain are links cast of malleable iron or Promal (Duramal). It is furnished with carbon steel heat treated pins and carbon steel case hardened bushings as standard. However, stainless steel pins and bushings can be provided when specified.
