Impurities have a great impact on the daily production of stone mill flour machinery. On the one hand, they will cause wear to the parts of the equipment, on the other hand, they will also reduce the quality of processed products and improve the ash content in products. Therefore, manufacturers need to pay attention to the cleaning of impurities in raw grain of stone mill flour machinery if they want to obtain more income. So what are the basic requirements for impurity cleaning of stone flour machinery?

雜質(zhì)會造成石磨面粉機生產(chǎn)故障：如含有秸稈、雜草、紙屑、麻繩等體積大、質(zhì)量輕的雜質(zhì)，容易使輸送管道堵塞，妨礙生產(chǎn)順利進行，或阻塞石磨面粉機的喂料機構(gòu)，使進料不勻，減少進料量，降低設備的工藝效率和加工能力。有時還會堵塞篩孔，使糧粒混入大雜質(zhì)中，造成糧食的浪費。

Impurities will cause the production failure of the stone mill flour machine: for example, containing impurities with large volume and light weight such as straw, weeds, paper scraps and hemp rope, it is easy to block the conveying pipeline, hinder the smooth progress of production, or block the feeding mechanism of the stone mill flour machine, make the feeding uneven, reduce the feeding amount, and reduce the process efficiency and processing capacity of the equipment. Sometimes, the screen hole will be blocked to make the grain mixed with large impurities, resulting in the waste of grain.

雜質(zhì)可能導致石磨面粉機損壞。如雜質(zhì)中含有石塊、金屬等堅硬雜質(zhì)，在加工過程中容易損壞石磨面粉機清理機械，影響設備工藝效果，增加維修費用，縮短設備使用壽命，甚造成工傷事故和設備事故;堅硬雜質(zhì)與設備金屬表面間的碰撞及摩擦，還有可能產(chǎn)生火花，引起火災及粉塵爆炸。

Impurities may cause damage to the stone flour mill. If the impurities contain hard impurities such as stones and metals, it is easy to damage the cleaning machinery of the stone mill flour mill during processing, affect the process effect of the equipment, increase the maintenance cost, shorten the service life of the equipment, and even cause industrial accidents and equipment accidents; The collision and friction between hard impurities and the metal surface of the equipment may also produce sparks, causing fire and dust explosion.

降低石磨面粉成品品質(zhì)。物料中的雜質(zhì)含量高，這些雜質(zhì)在加工的時候混入面粉成品中，如不清理，會降低成品純度，影響成品和副產(chǎn)品的質(zhì)量。因此，石磨面粉機須對雜質(zhì)進行清理，以保證產(chǎn)品質(zhì)量和生產(chǎn)。

Reduce the quality of stone flour products. The content of impurities in the material is high. These impurities are mixed into the finished flour during processing. If they are not cleaned, the purity of the finished product will be reduced and the quality of the finished product and by-products will be affected. Therefore, the stone flour mill must clean up the impurities to ensure product quality and production safety.

而面粉廠的規(guī)模大小直接影響工藝流程的繁簡和選用設備的類型及數(shù)量。對于大中型廠而言，清理流程相對說來要完善些;小型廠由于投資條件的限制，設備較少，清理流程也簡單些。但為了保證產(chǎn)品質(zhì)量，清理流程不應因為廠小而過于簡略。因此，在這種情況下，可選用結(jié)構(gòu)緊湊、具有多種功能而且工藝效果較好的組合清理設備，以保證基本的清理工序和必要的清理道數(shù)。

The scale of flour mill directly affects the complexity of process flow and the type and quantity of equipment. For large and medium-sized plants, the cleaning process should be relatively improved; Due to the limitation of investment conditions, small plants have less equipment and the cleaning process is simpler. However, in order to ensure product quality, the cleaning process should not be too simple because the plant is small. Therefore, in this case, the combined cleaning equipment with compact structure, multiple functions and good process effect can be selected to ensure the basic cleaning process and the necessary number of cleaning passes.
