When the drive device of feeder starts to run, the drive sprocket drives the chain to move horizontally in the conveying box and drags the material forward at the same time.

When the chain and the material through the rotary teeth roller in the crushing box, because the large material cannot pass through the specific space between the teeth roller and the base plate, the large material will be knocked, squeezed and stretched by rotating toothed rollers until broken into small materials which are allowed to pass through. 

Feeder breaker is mainly composed of chain conveyor and roller crusher two parts.

	CONVEYOR   PARTS Chain scraper conveyor mainly composed of drive device,chain scraper,conveying box and tension device. Adjusting the frequency converter can change the motor speed,which can change the running speed of the chain,and it can realize the purpose of adjusting the feeder breaker handling capacity.
CRUSHER PARTS
Hammer Crusher： The Hammer crusher is connected to the motor by the triangular belt.The height of the Hammer crusher can be quickly adjusted by means of a hydraulic device to adjust the discharge size of the crushed material in order to meet the needs of different customers.
	Teeth Roll Crusher: Powerful function teeth roll with picks and a pick pattern designed for chain scraper conveyor to crush material to the desired output size.Since the material is broken,not squashed, the lumps are consistent,producing less waste material and maximizing product value.

FEEDER BREAKER FEATURES

Feeder breaker can be fed directly by truck or loader,saving other types of feeding equipment.	Reducing or completely eliminating the excavation and civil work,greatly reducing equipment cost and civil engineering cost.
The broken teeth are arranged symmetrically at intervals,and the broken surface is fully covered without blind spots,this can not only break the hard material,but also minimize the production of fine.	The feeder breaker has the characteristics of light weight,small volume,flexible arrangement and convenient movement.
Spare parts replacement is simple and convenient, reducing downtime maintenance time and saving operating costs.
