Description

【考案の詳細な説明】 本考案はメゾイヤ型乾式粉砕機に関わるものである。[Detailed explanation of the idea] The present invention relates to a Mezoyer type dry crusher.

現在のメゾイヤ型乾式粉砕機は、砕料を投入しても乾式
のため、湿式粉砕機に比して砕料の槽内均一分布が時間
を要し、不十分になりがちで、均一粉砕が効果的になさ
れない欠点がある。Current mezoyer-type dry crushers are dry even when the crushed material is input, so compared to wet-type crushers, uniform distribution of the crushed materials within the tank takes time and tends to be insufficient, resulting in uniform pulverization. There are drawbacks to not being able to do it effectively.

湿式粉砕機においては砕料を含む液体をスクリーン等の
分離装置を介してメゾイヤと分離し一旦粉砕機本体外に
取出し、ポンプで再び本体に投入する循環方式がとられ
ている。In a wet type crusher, a circulation system is used in which the liquid containing the crushed material is separated from the mesoir through a separation device such as a screen, taken out of the crusher body, and then introduced into the crusher body again using a pump.

しかし、乾式粉砕で同様の方法はメチ゛イヤと砕料の分
離が乾式のため困難である。However, a similar method using dry pulverization is difficult because the separation of the methane and the crushed material is done in a dry manner.

本考案はこれらの欠点を除去するもので、砕料抜出部で
メゾイヤと砕料を分離せず、同時に粉砕機本体から抜出
し、スクリューコンベヤ等で投入部に運び再び粉砕機に
投入し、メゾイヤを含めた循環粉砕系を形成するもので
ある。The present invention eliminates these drawbacks, and instead of separating the mesoir and the crushed material in the crushed material extraction section, they are simultaneously extracted from the crusher main body, conveyed to the input section by a screw conveyor, etc., and then fed into the crusher again. It forms a circulating grinding system including
