1. Positive Displacement Blower

The first machine is the blower package.

From your motor tag I can read:

• 5 HP

• 230/460V

• 3 Phase

• 1740 RPM

• US Electrical Motors

The blower itself appears to be a Roots-type positive displacement blower.

Features visible:

• inlet silencer

• discharge silencer

• oil reservoir

• oil cooler

• pressure gauges

• flexible couplings

This blower does not create huge CFM like a centrifugal fan.

Instead it creates:

• constant airflow

• higher static pressure

• very stable vacuum/pressure

Typical performance for a 5 HP Roots blower:

• 200–600 CFM

• 5–15 PSI pressure capability

• or equivalent vacuum

Perfect for aspiration systems. It provides consistent airflow regardless of product loading.

2. Carter Day Aspirator

The large blue machine marked:

CEA Carter Day

is the separator.

Inside is a series of cascading decks where the seed repeatedly falls through controlled airflow.

The blower pulls air through the falling grain.

Heavy product falls.

Light product is lifted.

It separates:

• sticks

• dust

• chaff

• empty seed

• cracked seed

• leaves

• hulls

• fines

without using screens. Carter Day has long produced aspiration equipment for grain and seed processing.

3. How it works

Product flow is roughly:

Feed

↓

Gravity feed

↓

Carter Day separator

↓

Good seed exits bottom

↓

Dust/light material exits air stream

↓

Cyclone

↓

Dust discharge

↓

Clean air continues to collector

4. Kice Cyclone

Your gray cyclone is a standard cyclone separator.

Purpose:

• separates air from product

• removes dust

• prevents material entering blower

• recovers lightweight product

The cyclone is large enough I'd estimate around

400–800 CFM

capacity.

5. Rotary Airlock

The Kice rotary valve tag is readable.

It appears to be:

Model beginning with 1410

Manufactured:

May 17, 2011

Made in USA.

The rotary airlock allows material to discharge while maintaining the pressure differential in the aspiration system.

6. Distribution Manifold

The white manifold with four labeled outlets:

• Overhead

• Big Mixer

• West Bin

• East Bin

is simply a gravity distributor.

One inlet.

Four selectable destinations.

Very common in feed mills.

7. White Machine

The large white machine with multiple inspection doors looks like a gravity screener or scalper.

Likely used ahead of the aspirator.

Purpose:

• remove rocks

• remove large trash

• remove oversized material

before aspiration.

Capacity Estimate

Based on:

• 5 HP blower

• Carter Day body size

• cyclone diameter

• airlock size

I'd estimate this system was designed for approximately:

Actual capacity depends heavily on the product density and the degree of cleaning required.
