Based on the observation of moved lump coke,the original declaration position angle of the lump coke in screening tube was calculated with mathematic method,and the optimum rolling speed for mula of the screening tube was deduced.

Solid caboodle conveyance model of shale shaker with roller screen;

Based on the analysis of the force of wet solid on the non-submerging roller screen,the single solid conveyance model is built,and the throwing coefficient,conveyance velocity of non-submerging roller screen and their calculating methods are given.

In order to quantitatively analyze the regular conveyance pattern of solid grain on the roller screen,the forces acted on solid grains on the screen were analyzed.

Research on theories of the trommel screen separating municipal solid waste;

5XY-5 cylinder screen grader was developed basing on the national key project, aiming at the existing problems of traditional products in China.

Hence, a cylinder screen seed corn grader used in large and medium-sized seed processing plant is designed.

In this paper, we analyzed the cleaning principle of the two-fan cylinder screen unit, surveyed the flow field of the cleaning section in three conditions.
