griyyly feeder

The Vibrating Grizzly Feeder is used to separate ROM feed material into fractions prior to the primary crushing stage of the process. The feeder takes a bin load and is often installed horizontally but to improve material flow they can be installed up to a maximum 10-degree downslope. The feeder is mounted on springs and vibrated via a mechanism located underneath the pan. The vibration force is angled to the feeder, pointing toward the discharge end. This action of the vibrator forces the material toward the discharge end while segregating the material, causing the finer particles to move toward the bottom of the load.

Capacities range from 250 tph through to 2500 tph. The feeder operates at a minimum of 4G’s force with an approximate of 10mm. The discharging bars are interchangeable, adjustable and individually replaceable. The feeders are powered by two out of balance vibrating motors complete with feed rate control and each having individual overload protection.

stacker reclaimer

The Stacker is used for preparing the stockpile with the incoming material. The material coming on the yard conveyor is raised by a tripper attached to the stacker and discharged into the boom conveyor which carries the material up to its end to form different types of stockpile.

As the boom’s inclination can be adjusted and the boom itself can be slewed, it gives room for various methods of building bulk material stockpiles. Also, the machine travels continuously to-and-fro so that the pile is built up layer by layer.

The Reclaimer is used to pick up the material from the stockpile for onward discharge. A rotating bucket wheel with several buckets around the circumference is mounted at the end of a long luffing and slewable boom. Bucket wheels cuts into the pile with to-and-fro movements of the boom across the pile. The material picked up by the buckets is discharged on to a reversible boom conveyor running along the boom.

Stacker cum Reclaimer is a combination of both the function of Stacker & reclaimer and is an effective solution for stockyards. Stacker cum reclaimer as a rule, consist of a luffing boom mounted on a slewable superstructure and balanced by the counterweight mounted on its arm. These are supported on the undercarriage which travels on wheels running along the rail track. Both the bucket wheel boom and the counterweight boom are hinge-mounted on the superstructure and guyed by ropes or tiebacks via a pylon. The bucket wheel boom is raised or lowered with the help of hydraulic cylinders or cable winches. The reversible boom conveyor discharges the material at the center of the machine from where it moves down to conveyor or receives material from yard conveyor.

vibrating feeder/Screen
Vibrating screens shutterstock_744276172 [Converted]-01

A Vibrating Feeder consists of a trough mounted on a stiff base frame with springs in between to convey bulk material through vibration. Inclination and stiffness of springs determine the vibration angle and position of resonance. These are classified based on the source of vibration exciters where feeding rate is controlled by variable vibration amplitude & frequency which are either (I) electromagnets through thyristor controller; (II) mechanical exciters through shafts and unbalanced masses

The determination of screen capacity is a very complex subject.  A general rule of thumb for good screening is that “ the bed depth of material at the discharge end of the screen should never be over four times the size opening in the screen surface for material weighing 100 lbs/cuft or three times for material weighing 50 lbs/cuft.  The material flow in the screening media varies between 0.2 m/s to 0.25 m/s. The high frequency and low amplitude operation ensure a faster material travel speed without loss of screening efficiency.

The slope of the Inclined screen is fixed between 15 to 30°, although the stroke can be adjusted to the required level to improve efficiency of screening. The working stroke of an inclined screen is between 8 to 12mm.

 A Horizontal screen has slight incline between 0 to 5°. Horizontal screens are equipped with drive mechanisms that produce elliptical vibration motion at the required stroke. The exciter mechanism in horizontal vibrating screen combines the advantages of linear and circular vibration types in elliptical vibration. The stroke of horizontal screens may be adjusted in a range of 14 to 20 mm with a 750-rpm rotational speed.

screw conveyor

A Screw Conveyor consists of a circular or “U” shaped tube in which helix screw rotates. The Screw Conveyor is capable of handling variety of materials based on material characteristics such as flowability, moisture content, temperature etc.  Material is pushed along the bottom of the tube by the helix. These conveyors are not practical for high capacity or long transportation distances due to high power requirements. It varies in size from 75 to 400 mm in diameter and from 1m to more than 30 m in length.

The capacity of a Screw Conveyor is dependent upon three principle factors, like Conveyor Diameter, Trough Loading & Speed. When deciding upon trough loading, less abrasive and free flow tends to better be conveying.
