3. The working principle of the spiral chute
The divider is placed freely on the cross (or tripod) of the
support table. The uniform pulp is slowly fed to the surface of the
spiral groove through the feeding groove installed at the head end
of the spiral groove for sorting. The end of the spiral groove is
equipped with a valve block-type product intercepting groove, which
divides the sorted products into three (or four) grades in the
radial direction. The cut-off width of each product can be changed
by adjusting the position of the valve block. The product gathering
bucket is a concentric annular cylinder, which collects and exports
the intercepted multi-head ore streams separately. The cross
section of the spiral chute, the change of the slope of the curve
is especially suitable for the selection of fine particle
materials. The mineral processing equipment has the advantages of
simple structure, no moving parts, light weight, no noise,
convenient configuration, installation and maintenance.
4. Structural characteristics of spiral chute
The glass fiber reinforced plastic spiral chute consists of six
parts: feeder, ore feeder, spiral groove, product intercepting
groove, product gathering bucket and groove bracket (including
cross or tripod). The helical groove formed by the helical flakes
is the main component. The spiral pieces are made of glass fiber
reinforced plastic (glass fiber reinforced plastic) and are
connected together by bolts. The selected surface of the spiral
groove has a prefabricated wear-resistant layer. The mineral
processing equipment has the advantages of light weight, firmness
and durability. The upper part of the spiral groove is provided
with a multi-pipe ore-feeder and evenly distributed ore, which is
easy to control.
