Airlock Discharge Valve Rotary Rigid Impeller Feeder For
Mining/Grain Industries
Product Description
The rigid impeller feeder is commonly known as the unloader, also known as the ash discharge
valve, which is specially designed as bulk material discharge
device under dust-moving equipment, silo, storage bin, hopper
etc.The JL type and JLT type rigid impeller feeder use a rotating
impeller with a compartment to transfer powder and small granular
materials from the upper storage bin or hopper to the lower
discharge port for uniform feeding or shifting. material. When
using constant speed feeding, the machine can achieve uniform
feeding. If the speed control motor is used, the speed of the
impeller can be adjusted and changed at any time as needed to
achieve the adjustment of the feed amount. The rigid impeller
feeders produced by our factory are divided into two types. The JL
type is non-speed-regulating type, equipped with cycloidal pinwheel
reducer, JLT is speed-adjusting type, equipped with slip speed
regulating motor and ZQ series reducer.

Working Principle
The rigid impeller feeder is composed of a rotating impeller with a
compartment, a machine body, and a new cycloidal pinwheel reduction
motor. Small size, reliable work, good sealing and wear resistance.
The working principle of the rigid impeller feeder: when the
impeller is driven by the transmission mechanism to rotate in the
body, the powder material falling from the upper separator (or
hopper) will enter the impeller compartment through the feed port,
and will be It is sent to the discharge port for discharge. During
the whole working process, it can continuously ration feed and
discharge.
Main Features
1. Material of silo discharge: stainless steel, carbon steel.
2. Compact structure
3. Good sealing performance
4. Variable speed, with slip speed motor and ZQ series reducer.
5. Wide range of application.
Application
Rigid impeller feeder is widely used for nuts, almond, sunflower
seed, cotton seed, grain cereals, chestnut, coffee, grain, sugar,
spice, cement, calcite, glass powder, marble powder, plastic
pellets, sawdust, coal etc.
