The method relates to suspending cement clinker particles in a gas moving at a high velocity and causing the gas and particles to impinge upon the wall areas which are normally subject to caking at sufficient velocity to dislodge the caking.,下面是Abrasion of caking专利的具体信息内容。

1. A method of counteracting caking tendencies in a suspension preheater, such as cyclone preheater, which feeds a rotary kiln with preheated cement raw meal so as to be burnt to cement clinker, comprising: suspending cement clinker particles in a gas moving at a high velocity, said cement clinker particles having no detrimental influence upon the burning process in the rotary kiln or upon its product; causing said gas and particles to impinge upon internal wall areas of the preheater which are normally subject to caking at sufficient velocity to dislodge the caking; permitting these particles to exit from the preheater together with preheated cement raw meal exit flow; and feeding said particles to the kiln together with said preheated cement raw meal exit flow.
2. The method according to claim 1 further comprising intermittently suspending said cement clinker particles in said gas moving at a high velocity thereby intermittently dislodging caking on said internal wall areas of said suspension preheater.
3. The method according to claim 2 further comprising suspending cement clinker particles which are approximately in the order of about 2 mm in size.
