When processing hard wheat with small flour processing equipment, the slag grinding process of "clearing powder first, then adding slag" is usually adopted. The main characteristics of this process are wide range of flour cleaning, high extraction rate of first-class high-quality coarse grains, uniform quality of materials into slag mill, low grinding turnover rate, which are suitable for processing wheat with high hardness. The disadvantage is that the cleaning equipment is used a little more, the slag grinding materials are not selected, and the role of slag grinding is not fully played.

小型面粉加工設(shè)備加工軟質(zhì)小麥時(shí)，可采用“先入渣。后清粉”的站流程，該流程的主要特點(diǎn)是充分發(fā)揮了渣磨系統(tǒng)的作用，清粉范圍稍窄，清粉機(jī)使用數(shù)量較少，適合加工軟質(zhì)小麥。缺點(diǎn)是渣磨物料的質(zhì)量不均勻，小型面粉機(jī)周轉(zhuǎn)率高，一等品質(zhì)的粗粒提取率稍低。

When small flour processing equipment is used to process soft wheat, it can use "slag first". The main characteristics of this process are that it gives full play to the role of slag grinding system, the scope of cleaning is slightly narrow, and the number of cleaning machines is less, so it is suitable for processing soft wheat. The disadvantages are that the quality of slag grinding materials is not uniform, the turnover rate of small flour machine is high, and the extraction rate of first-class quality coarse grains is slightly low.

提取高質(zhì)量面粉時(shí)，通常采用“先清粉，后入渣，再清粉”的渣磨系統(tǒng)，該流程的主要特點(diǎn)是不僅充分發(fā)揮了清粉系統(tǒng)的作用，而且充分挖掘渣磨系統(tǒng)的潛力，盡可能多提取一等品質(zhì)的粗粒、粗粉，該工藝有能力提取數(shù)量較多的阿高精度面粉。缺點(diǎn)是清粉機(jī)使用臺(tái)數(shù)較多，操作管理要求稍高。渣磨平篩中分級(jí)篩的選配是根據(jù)平篩的流量、篩理物料的特性和達(dá)到制粉流程流量平衡的要求而決定的。

When extracting high-quality flour, the slag grinding system of "first cleaning, then slag, then cleaning" is usually used. The main feature of this process is that it not only gives full play to the role of the cleaning system, but also fully exploits the potential of the slag grinding system to extract as many first-class quality coarse grains and coarse flour as possible. This process has the ability to extract a large number of high-precision flour. The disadvantage is that the number of cleaning machines used is more, and the operation and management requirements are slightly higher. The selection of grading screen in slag grinding flat screen is determined by the flow rate of flat screen, the characteristics of sieving materials and the requirement of flow balance in pulverizing process.
