The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. ... Feed enters from a hopper and passes through a grizzly screen to remove oversize; Gyratory crushers are operated in open circuit. The feed is limited to 1 to 1.5 meters in size. Thus, based on ...
A common misconception is that a grizzly can eliminate the problem of oversized material. It is true that, with a grizzly in place, boulders are less likely to enter the primary crusher. However, a grizzly is still susceptible to blockages – mine personnel need to remove oversized material or schedule rock breaking. A proactive alternative
Standard (Secondary) Cone Crusher (Refer to Fig. 1): The Standard Cone crusher is normally applied as a secondary crusher in a multi-stage crushing circuit. The small diameter feed distributor and the wide throat opening at the top of the liners enable the Standard Cone crusher to accommodate the larger feed produced by the Primary …
Wide application: Suitable for both dry and wet crushing, for materials with up to 15% moisture. One-time forming: Eliminates the need for primary and secondary crushing, reducing costs by approximately 40%. Large feed opening: Handles feed sizes up to 1000 mm, making it ideal for coarse crushing. Non-clogging: Designed to ensure …

The integrated grizzly with efficient bypassing of fines boosts crusher capacity, reduces energy consumption and increases liner lifetime. A particularly effective kinematic of the oscillating roll with constant stroke in the entire crusher cavity allows for higher reduction ratio and more effective use of crushing energy.
This article focuses on a feeder type that plays a critical role in the efficient operation of primary crushers – the vibrating grizzly feeder (VGF). {{image2-a:r-w:325}}The purpose of a VGF is two-fold: to absorb …

The first step in choosing a primary crusher takes place at a high level. It's necessary to identify the purpose the crusher will be used for. This purpose is a given that precedes the entire decision-making process. Sometimes, a measure of guidance or experience is needed. The two main components to consider when i…
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The …
Grizzly feeders are used to separate raw materials into two fractions to send to the primary crusher only the largest elements and to eliminate the under size. In quarries, this operation is to avoid sending to the crusher material which does not need to be crushed. ... When installed ahead of the primary crusher it performs coarse sizing and ...

Vibrating Grizzly Feeders & Grizzly Bars. ELRUS Hydraulic Grizzly Bars and Vibrating Grizzly Feeders work in conjunction with each other to remove oversize rock and fines from the primary crusher feed to optimize production and reduce wear and tear on equipment.
An apron feeder withdraw the ore and discharges this onto the Vibrating Grizzly. The Vibratory Feeder's units are especially designed for harsh operations where lumps requires separation from fine ore. The fine ore passes through the tapered grizzly fingers and bypassing the crusher, whereby the lumps are fed into the primary crusher.
