Питатели – это приспособления, которые регулируют дозированную подачу сыпучих грузов из бункеров, контейнеров, воронок и других емкостей.
Современные питатели бывают таких видов:
- пластинчатые;
- качающиеся;
- ленточные;
- грохот-питатели;
- пылепитатели;
- вибрационные.
При этом каждый из них выполняет отдельно отведенную задачу. Пластинчатые питатели предназначены для подачи грузов при помощи ленты-конвейера, состоящей из пластин. Пылепитатели подают угольную пыль в пылевые горелки. Качающиеся питатели «просеивают» материал при помощи лотка, который выполняет поступательно-возвратные движения. Вибрационные питатели используют для выгрузки кокса, известняка, обожженных окатышей, а также для загрузки вагонов.

Worm feeders of WF-type
Are designed for handling bulk products (with bulk density from 0,4 to 4,5 t/min) to weight batcher, mixing machines and other devices.
Are transporters where loads move by dragging on fixed chute (pipe) with swiveling rotor blades. -
Swinging feeder
Is designed for the uniform delivery of inadhesive bulk materials with the size less than half the width of the tray from bunkers, cones and other storage capacities to technological cars or transporting devices.
-
Scraper-pulley feeder SPF-350
Designed to prevent the escape of gases through the lower window of unloading units of drying and dust collecting installations with material’s moisture level varying from 5% to 12%, and with the fractional composition of the material of 0 … 40 mm.

Paddle pulverized coal feeder PPCF
Designed for uniform supply of coal dust of needed quantity from the bin into dust pipes to burners, as well as for bin rooffing to avoid own-accord leakage of dust into the dust pipe the smoke damper machine is used.
-
Double screw type conveyor
Designed for coal dust transportation to dust feeders and is used on thermal electric power stations.

PP Type Plate Feeders
The plate feeders are designed for uniform delivery of different industrial materials from the bins and other reservoirs. It is a continuous belt of metal links up to 2400 mm wide, and 18 m long across shaft axes. The belt rests upon the upper and bottom rollers mounted in the bearings on the frame.
