Description

The Fote Double Roll Crusher is ideal for primary and secondary reduction of ROM coal, washed coal, middlings, screenings, slag, moist clay, limestone, cement, potash, rock, sulfur, lignite, pyrite and other materials where minimum fines are required.

Fote brings over a century of experience to the design, performance and capacity of these machines to provide unmatched product control with dependable operating efficiency, minimum maintenance and long service life.

The commonly seen roller crusher falls into three types: single roll crusher, double teeth roll crusher and four roll crusher.

In the working process, material falls in between the two rollers, and will be crushed. Normally, the material will be discharged from the bottom. When encountering material with high hardness, the rollers will automatically concede by hydraulic cylinder or spring which will increase the space between the two rollers, resulting in the falling of material with high hardness and uncrushable material, to protect the machine from damage. Changing the space between the two rollers can definitely control the maximum particle size of discharged material.

Each roll assembly comprises of renewable and reversible toothed segments, bolted and keyed to a robust hexagonal hub with the nuts inside the hub. Locking nuts are securely located in fabricated pockets in the drum. This enables removal and replacement of segments from the outside using only one tool (Allan Key).

Bolt heads are protected from excessive wear by being counter sunk in recesses on each segment. Teeth are arranged in a staggered formation on the segments to prevent tooth on tooth impact. Tooth proportions are designed for the particular product requirements.

The rolls are separately driven by two identical motors, through sets of vee belts which are connected between the gearbox pulley and the flywheels.

The drive arrangement is free standing with the electric motors mounted on adjustable base plates.
