Syntron® Crusher Loading Feeders from FMC Technologies

FMC Technologies introduces its latest advance in vibratory feeder technology, the Syntron Crusher Loading Vibrating Feeder.

Uniform Material Discharge Directly to the Crusher.

The Crusher Loading Feeder is an innovative, cost effective alternative to the ‘feeder-plus-rotary distributor’ setup commonly used to ensure uniform material feed to cone crushers. FMC’s Crusher Loading Feeder distributes material uniformly to the cone, eliminating the need for a rotary distributor in secondary, tertiary and quaternary crushing applications. More uniform material distribution leads to a consistent amp draw on the crusher, longer life for crusher components, and improved fracture ratios.

Suspension framework is mounted on a trolley that can be moved out for crusher maintenance.

The new Syntron Crusher Loading Feeder is a traditional mechanical style vibratory feeder with a peripheral discharge. The Crusher Loading Feeder retains the high reliability and robust design of the mechanical feeder; the peripheral discharge, which has its origins in distribution of snack foods and cereals onto radial scales, enables equal distribution of fine and coarse product. The trough is fully lined to account for wear, and it is suspended by the same method as traditional vibratory feeders. The suspension framework is mounted on a trolley that can simply be moved out of the way for crusher maintenance.

The specially configured discharge blended fines and coarse materials to provide uniform distribution of material to the cone.

In side-by-side installations of a feeder-plus-rotary distributor and a Syntron Crusher Loading Feeder directly feeding the crusher, the Crusher Loading Feeder delivered superior, cone friendly performance. The specially configured discharge blended fines and coarse materials to provide uniform distribution of material to the cone.

Crusher plant maintenance

Convenient maintenance is so important in the quarrying crusher plant industry. Maintenance can be defined as working on something to keep it in a functioning and safe state and preserving it from failure or decline. Maintenance activities at quarries range from the maintenance of machines, equipment and vehicles to the keeping of roadways on site in good order, attending to such matters as providing edge protection and securing excavations.

It’s important to keep structural costs down, to design for ease of maintenance and operation, and to combine best practices with advances in fabrication and erection.

Best installation for crusher plant

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.Since the crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation.

The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with today’s tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor.
