Criteria of design and selection of a crusher machine

Compression crushing is required, and the expected production capacity is fixed in the choice between a jaw crusher and a gyratory crusher equipment. For capacities below 600 t/h, the jaw crusher is recommended, with a simple effect if the rock is very hard and very resistant. The reduction ratio is at most 4 to 5, and the size of the most significant blocks determines the choice of the

Primary Crusher Selection & Design

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.

Crushing of Ores and Rocks in Mineral Processing

The gyratory crusher; can produce 600 to 6000 t/h crushed ore, depending on the size. Jaw crushers; can provide up to 1,400 t/h depending on their tightening which determines the output size. The impact crusher can also be used in primary stage, but its use is usually limited at this stage. Regardless of the type of crusher used, it will always be heavy and very able to split large boulders.

2014-02-26· CHARACTERISATION UNDERSTANDING THE ORE BODY AND THE METALLURGY Rock Mass Properties • Standard rock mass properties are usually obtained as geotechnical information from drill core and include: • Rock Mass Rating • Rock quality designation • Point load Index • Young’s Modulus • Poisson’s Ratio • Unconfined Compressive stress • In-situ block size • Joint

Crushing Plant Design and Layout Considerations

Ore characteristics are a critical element in both crusher selection and plant design. Dry ores require greater provisions for dust suppression and collection, including dust enclosures around screens, sealing on conveyor skirts, and vacuum and wash-down systems. Wet, sticky ores can plug chutes, reduce surge capacity, and decrease the live storage capacity of bins and silos. To address this

Production line to the ore crusher stone crusher includes jaw crusher, cone crusher, impact crusher, impact crusher and so on. Ore crushing production line will be broken based on the principle of different material properties and requirements plus a comprehensive selection of stone crusher. According to the method usually crushed stone

(PDF) Material Selection for Crusher Jaw in a Jaw Crusher

Primary crushers are commonly designed to operate 75% of the available time, mainly because of interruptions caused by insufficient crusher feed and by mechanical delays in the crusher (Lewis, et.al, 1976). The reclaiming operations of the primary crusher products from the ore storage to the disposal of the final crusher product involves the secondary crushing process, it is usually between 0

Advanced comminution modelling: Part 1 – Crushers

2020-12-01· The friction coefficients are 0.5 for rock-crusher and 0.6 for rock-rock contacts. The normal spring Fig. 4 shows the flow and breakage of material through the crusher for the softer ore with an E b = 1100 J/kg. The feed material is large and so is coloured from red to yellow to green for the smallest feed. The counter-rotation of the rolls predisposes particles to being trapped between

Optimized crusher selection for the cement industry

The properties of raw materials required for the cement production differs at a wide range. The limestone deposits used today as base material show very different prop- erties regarding hardness, abrasiveness and stickiness. To optimize the crushing and at the same the investment and operating costs different types of crusher are avail-able on the market. This paper should give a short

We have sold our jaw crushers to many different industries over the years, but the hard rock mining industry is still the #1 purchaser of our jaw crushers. The hammer mill or ball mill takes the <3/4″ discharge from the jaw crusher and pulverizes it to liberate the values in the ore (usually gold), and one of them is a component of our Turn-Key Ore Processor. The size of the powder from a

Jaw Crusher ScienceDirect

2016-01-01· The ore or rock is fed to the crusher where the jaws are furtherest apart, i.e., at the maximum opening or gape. When the jaws come together the ore is crushed into smaller sizes and slip down the cavity. In the return stroke, further reduction of size is experienced and the ore moves down further. The process is repeated till particles having size less than the bottom opening or set pass
