Subtraction = Addition

The advanced engineering of the Fuller® Random Flow™ (FRF) gravity blending system delivers increased capacity, productivity and savings by decreasing:

Power consumption
Maintenance
Dust
Capital costs
Kiln fuel consumption
Air flow

The innovative process and simple design of the FRF system achieves accepted blending efficiencies for dry, pulverized, free-flowing particles saving you both time and money.

Competitive Advantage

The FRF gravity blending system is FLSmidth’s response to the cement industry’s demand for a more energy-efficient, cost-effective system. Designed for higher production at lower costs, the FRF system has already proven its capabilities in new installations and retrofits worldwide. In retrofits, it can increase your capacity up to 40% over fluidized systems while decreasing kiln fuel costs through a more uniform blend.

Free Power

The FRF system minimizes costly mechanical power requirements and maximizes the "Free" power of gravity for a variety of blending applications. In fact, the FRF system can reduce power consumption from 2.0 kWh/metric ton of raw mix to as low as 0.07 kWh/ metric ton! In addition, the FRF system utilizes oil-free dry air from equal-size, positive-displacement blowers, offering uniformity of parts, less component wear and minimal lubrication requirements.

6² = 1 Powerful Solution

The FRF system is a cost-effective gravity blending system that requires low power consumption but provides high blending efficiency. The system is well suited to converting existing fluid bed blenders and storage silos to gravity blenders. The silo floor consists of six sectors. Each sector has six collection points. Blending is achieved by systematically withdrawing layered material from a total of thirty-six collection points. The material is withdrawn by low-pressure air in closed-type Airslide® conveyors from the collection points to the silo discharge. A relatively small inverted cone, centrally positioned over the silo discharge, prevents material from exiting without first flowing through a collection point.
