Airlock Feeder

1.Product Overview

An airlock feeder is a combined air sealing and quantitative feeding device,integrating air lock,discharging and metering functions in one unit.It is mainly installed under dust collectors,cyclones,silos and hoppers.It continuously and steadily conveys powder,granular and small lump materials,while isolating internal and external pressure differences,preventing air leakage and dust emission,and ensuring efficient and stable operation of pneumatic conveying and dust removal systems.

2.Working Principle

Driven by a motor and gear reducer,the precision rotor rotates steadily in the sealed housing.Material fills the rotor chambers from the top inlet,and is transferred to the discharge port with rotor rotation for uniform discharging.The closed rotor compartments form a reliable air barrier,which effectively blocks airflow backflow,maintains system pressure balance,and achieves air locking and feeding at the same time.

3.Main Structure

Drive assembly:motor,speed reducer and transmission parts

Heavy-duty sealed housing with standard flange connections

Multi-blade wear-resistant rotor

High-efficiency shaft sealing and bearing components

Optional wear liner,anti-blocking structure and inspection cover

4.Key Features&Advantages

Dual functions of airlock+feeding,compact and space-saving

Tight sealing performance,no air leakage and dust overflow

Uniform feeding and stable discharge capacity,easy speed regulation

High wear resistance and structural strength for long-term heavy-duty use

Simple operation,convenient maintenance and low running cost

Flexible customization for high temperature,anti-corrosion and explosion-proof conditions

5.Application Scope

Widely applied in environmental protection dust removal,building materials,chemical industry,metallurgy,mining,grain,feed and biomass industries.Ideal for fly ash,cement,limestone powder,ore granules,grain materials and various industrial bulk powders.

6.Common Types

Cast iron standard type,stainless steel food grade,high temperature resistant type,heavy wear-resistant type and explosion-proof customized type1.Product Overview
