1.1 The following 250T/24H flour mill is specially designed according to hard wheat.
1.2 This design adopts the technical process of extracting flour from medium and long flour scheme in the milling workshop and 14 MMD25/100 pneumatic automatic roller mills to consist the 5B8M2S2T milling technique which is full blown in Europe. 3B, 4B and 5B all have coarse and fine systems; bran pieces from upper section of plansifter is treated with bran scourer to shorten the process of break system. Middling system, semolina system and 1T system all adopt smooth rollers and combine with impact detacher to reduce the power of rear milling stage. 2T system adopts smooth rollers to give special treatment to material in T system in rear milling stage and thus plays the key role of reducing ash content. Roller’s contact length is 11.20mm/100Kg wheat•24h; sieving area is 0.090m2/100Kg wheat•24h; purifier’s unit sieve surface width is 1.89mm/100Kg wheat•24h.
