RANDOM-FLOW™ gravity

blending and storage system



Higher production, lower cost

Gravity blending

The advanced engineering o the

RANDOM-FLOW™ gravity blending and

storage system delivers increased

capacity, productivity and savings by

decreasing:

• Power consumption

•Maintenance

•Dust

•Capital costs

•Kiln uel consumption

•Air ow

The efcient process and simple design

o the RANDOM-FLOW system

achieves accepted blending efciencies

or dry, pulverized, ree-owing

particles...saving you both time and

money.

The RANDOM-FLOW system meets

the cement industry’s demand

or a more energy-efcient, cost-

eective system. Designed or

higher production at lower costs,

the RANDOM-FLOW system has

already proven its capabilities in new

installations and retrofts worldwide.

In retrofts, it can increase capacity up

to 40% over uidized systems while

decreasing kiln uel costs through a

more uniorm blend.

• Simple silo design

• Maximum clean-out capability

• Reduced installation cost

• Low power consumption

• Reduced maintenance

• Blending and storage

Free power

The RANDOM-FLOW™ system

minimizes costly mechanical power

requirements and maximizes the

ree power o gravity or a variety

o blending applications. In act, the

RANDOM-FLOW system can reduce

power consumption rom 2.0 kWh/

metric ton o raw mix to as low as

0.07 kWh/metric ton.

In addition, the RANDOM-FLOW

system utilizes oil-ree dry air rom

equal-size, positive-displacement

blowers, oering uniormity o parts,

less component wear and minimal

lubrication requirements.

The RANDOM-FLOW system is a

cost-eective gravity blending and

storage system that requires low

power consumption but provides high

blending efciency. The system is well

suited to converting existing uid bed

blenders and storage silos to gravity

blenders.

The silo oor consists o six aeration

zones. Each aeration zone has six

collection points. Blending is achieved

by systematically withdrawing layered

material through a gathering slide

rom a total o thirty-six collection

points.

The material is withdrawn by low-

pressure air in closed-type AIRSLIDE™

gravity conveyors rom the collection

points to the central silo discharge

point. A relatively small inverted cone,

centrally positioned over the silo

discharge point, prevents material rom

exiting without frst owing through a

collection point.

Low power, ecient

withdrawal rom storage

The multiple collection points ensure

uniorm withdrawal o material about

the entire oor area, closely resembling

a mass ow discharge. This allows

uidization rom small zones to

move material to the discharge point

resulting in material discharge using

very low power and low air volumes.
