Gyratory Crushers - Metallurgist & Mineral Processing Engineer

The breaking head gyrates inside an inverted truncated cone. These crushers are designed so that the head-to-depth ratio is larger than the standard gyratory crusher and the cone angles are much flatter and the slope of the mantle and the concaves are parallel to each other. The flatter cone angles help to retain the particles longer between ...

A non-contact technology, like a 20 kHz acoustic transmitter, is the best choice because of its narrow beam, self-cleaning capability, not affected by background noise in the crusher and will see through dust. Acoustic transducers have the ability to see through dust. Particles of dust in suspension are micron in size.

The secondary crushers are designated as Standard cone crushers having stepped liners and tertiary Short Head cone crushers, which have smoother crushing faces and steeper cone angles of the breaking head. The approximate distance of the annular space at the discharge end designates the size of the cone crushers.

The answer, the company says, is to reduce the wear on components instead of having to replace them so often. This is where off-line oil filtration and the company's CJC® Offline oil filter comes in. How clean is the crusher lube oil? With crushers being sited in very dirty and dusty environments, the oil gets highly contaminated with particles.

Impact Crushers Typical rules for primary crusher selection: Rule 1: Always use a jaw crusher if you can due to lower costs. Rule 2: For low capacity applications, use jaw crusher and hydraulic hammer for oversize. Rule 3: For high capacities, use jaw crusher with big intake openings. Rule 4: For very high capacities, use gyratory crusher.

Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when product shape is an important requirement but the proportion of fines produced needs to be minimized. Even though the reduction in fines produced may only be a few percentage points, this could represent a significant amount of material in a large ...

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. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

Technically, CJC ® Oil Filter is known for keeping oil clean, dry and without oxidation residues, which is documented over many years and in several cement production installations. When you choose CJC ® Oil Filter, you ensure a long lifetime of pumps, gearboxes, bearings and hydraulic components.

Secondary crushing (or intermediate crushing) accepts the material from the primary crushing stage and reduces it even further, whether for final product sizing or in preparation for final product sizing in the tertiary or quaternary stages. Tertiary and Quaternary Crushing

FORMER PRODUCT LINE. The HTI series was designed for the economic tertiary crushing of hard rock. It's a modular system, manufactured with the objective of fulfilling every task in the bulk materials industry. The machine's fittings, as well as its control, may be adapted to suit operators' individual requirements – including fully ...

crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen.

By constantly removing particles, water and oxidation from oil, CJC® Oil Filters can reduce wear on all mining equipment including crushers, mills, haul trucks and excavators, drilling equipment, and conveyor belt drives. Lifetime of oil and components can be extended by several thousand hours when you use CJC® Oil Filters.

This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

Oil is increasingly stressed as machinery tolerances become finer, often below 3 microns. Since particles of this size can cause immediate breakdown, reducing their number to as few as possible is a priority. Oil filtration is the most effective and economical way to remove smaller particles effectively. Research has shown that up to 6 times ...

MX™ Series cone crushers utilize a revolutionary technology that combines a rotating bowl with piston into one crusher. Known for lower operating costs, high uptime and consistent high-quality output, MX™ Series cone crushers are ideal for secondary, tertiary and quaternary stages in hard and soft rock applications.

The rock breaks and falls out the bottom. These types of crushers are usually applied as tertiary or quaternary crushers with less than 2" (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very application-specific. They are sensitive to abrasive materials ...

Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm (75 mm ...

The secondary crusher product is screened and conveyed to bins ahead of the tertiary crushers. The tertiary crushers operate in either open or closed circuit with a variety of arrangements available in positioning the tertiary screens. The screens can be placed above or below the tertiary crushers or in a separate screen house.

If after the secondary round of crushing, a tertiary reduction may be desired (sometimes even further). Particle sizes range from 100mm to 10mm during this final stage. Tertiary crushing is highly valuable in the mineral processing industry. The degree to which a material is reduced largely depends on how fine the material's final size should be.

Overall significantly reduced lost production! • Extended oil lifetime by 3-4 times, and no prema-ture oil degradation/aging i.e. 80% reduction in oil consumption • Up to 60% reduction in use of bushing on crushers • Up to 80% reduced downtime – less planned as

High oil temperature should stop the crusher feed and allow the unit to cool down. After the machine has cooled, further investigation of the high-temperature condition is needed before the machine is operated again. No oil flow should prevent operation of the unit.

Compression crushers can be used at the primary, secondary or tertiary stage, depending on the application. They are ideal for hard, tough and abrasive materials that are not sticky. Types of Compression Crushers Cone Crushers DDC-Sizers Feeder-Breakers Jaw Crushers Roll Crushers Sampling/Pilot Plant Crushers Impact Crushing

Horizontal shaft impact (HSI) crushers are used in primary, secondary or tertiary crushing stage. HSI crushers reduce the feed material by highly intensive impacts originating in the quick rotational movement of hammers or bars fixed to the rotor.

Three factors are of prime importance in selecting the size and type of the secondary crusher, or crushers: capacity; size of feed, size of product. You add to these the item of product characteristic, which embraces shape characteristic, and gradation. These are not always important, but they are sometimes very much so. Capacity of Secondary Stage
