So the material will first impinge there, crush and then falls smoothly on the belt. Please i want your opinion about this. Are we thinking on the right position?

Thank you in advance.

Get rid of the baffle you intend on installing and

add some slick liner material to the vertical sides

and slopw of the chute. in this way you bypass any

issues with remaining moisture in the filter cake.

I would be doubly sure to install a rubber belt scraper

at the head pulley of the conveyor. ■

The idea is certainly a good one, but not knowing the material properties or moisture it is difficult to say how or if it will work.

At the end, any object on the way is a potential for clogging, so I would also follow the comment with the well gliding liner and rather change the idlers below to an impact bed. In that way allowing for sure transfer of the material and avoiding idler/roller damages. ■

After opening the bombdoors the cake should be dropped straight onto the receiver without anything to stop it.

Impact is handled by reducing the idler pitch rather than by fitting impact rollers. The loaded running time is quite low. ■

A plate filter cake will normally be broken by impact on the side walls of the collecting hopper, so reducing some of the potential energy of free fall. Impact forces can be further reduced by fitting a narrow dispersing insert, but the insert shape shown on the sketch is too shallow, too wide and very likely to cause blockages at the small side clearances. Any insert must be robustly supported, self clearing and leave very generous clearances of the side walls. An inverted 'V' with sides at 80 degree inclination to half the width of the hopper outlet would divert the cake to the walls, fracture the cake and minimise impact. Facing the hopper with UHMDPE will also help to prevent build up on the walls and clear the hopper contents. ■
