·A crusher with a high choke point incorporated in its design is not appreciably affected by choke feed When these crushers are fully buried the choke point throttles back the material so as to prevent overloading the lower part of the crushing chamber and there is so little active crushing surface above the choke point that very few fines
·This is important especially in fine crushing Choke feeding maximizes the amount of multi layer crushing improves the shape of the crushing cavity as it wears and improves the crushing efficiency => Choke feed level for an HP cone crusher is 300 mm or more above the feed plate • The feed must be distributed evenly 360º around the crushing
·This is important especially in fine crushing Choke feeding maximizes the amount of multi layer crushing improves the shape of the crushing cavity as it wears and improves the crushing efficiency => Choke feed level for an HP cone crusher is 300 mm or more above the feed plate • The feed must be distributed evenly 360º around the crushing
·Segregation in crusher hopper Fine Coarse Fine Coarse Segregation is the enemy of optimum crusher performance and operating costs Remember crushers operating under conditions as indicated above suffer from cyclic pressure peaks and cannot safely be operated at settings reasonable with a non segregated feed
·Various feeding sizes 19 mm and quantities 500 1500 g were adopted to reveal the choke feeding intensity during crushing actions The efficiency of feeding properties was investigated through the response surface methodology RSM such as crusher performance feeding method and rock properties All these parameters
· Fines in the crusher feed is defined as material entering the top of the crusher which is already equal to or smaller than the crusher s closed side discharge setting As a rule of thumb the maximum number of fines in the crusher feed should not exceed 25 percent for secondary crushers or 10 percent for tertiary crushers
The cone crusher is a modified gyratory crusher and accordingly many of the same terms including gape set and throw apply The essential difference is that the shorter spindle of the cone crusher is not suspended as in the gyratory but is supported in a curved universal bearing below the gyratory head or cone Figure Major suppliers of cone crushers include Metso
·Choke feeding maximizes the amount of multi layer crushing and improves wear shape and crushing efficiency 1 Choke feed level for GP secondary crusher is at the level of the mantle fixing nut 2 Choke feed level for GP fine crusher is max 1 meter above the top bearing arrangement • The feed must be distributed evenly 360° across the crushing
·Cone Crusher Function zA cone crusher has an annular crushing chamber zThe CSS runs around the chamber so the action is basically rotational zRaw material enters the chamber on the OSS and is crushed one hlf lti lt bthCSShalf revolution later by the CSS zThis cyyp pcle takes place in most cone crushers 5 to 6 times per second
·Like the jaw crusher the cone crusher provides a relatively low cost crushing solution but there are application drawbacks that may make another crushing solution more appealing First cone crushers cannot accept all material sizes Any material fed to the crusher must be pre sized for that particular crusher usually 200mm or less
Choke feeding produces fines; desirable for liberation purposes Typical Jaw Crusher Operation Product size is smaller than the open side setting Typical operating and performance characteristics Top Feed Size = x Gape When the feed drops into the crusher the mantle squeezes the rock against the concave surface
·• Stroke adjustment enables choke fed condition for different feed rates Choke feed maximizes capacity shape and reduction ratio • Short stroke lowers power draw and piston pressure and helps the crusher to reach tighter CSS Typically best product shape and size fraction share is achieved around the CSS
·Gradations and capacities are most often based on a typical well graded choke feed to the crusher A choke feed is when the crusher cavity is kept full without spilling out over the top of the crusher A minimal feed is when the crusher cavity is kept fairly low just enough to ensure the crusher continues to work
5 ·Feeding Your Jaw Crusher Jaw crushers are often choke fed to maximize production speed Choke feeding results in stone on stone crushing which can help break apart more flaky materials However choke feeding also often results in a finer output Trickle feeding will result in larger products but also reduce capacity and jaw crusher efficiency
The adjustable stroke also allows you to attain proper choke feed conditions and optimum crusher settings ensuring the maximum yield of a required end product size The crusher automation on the other hand provides smooth process adaptation full crushing process automation and ensures that your crushing machine runs at its optimal
choke feeding cone crushers information for buying a used jaw crusher and how jaw crushers are used for primary crushing in mining construction
·Uniform distribution of feed material around the cone crusher inlet is good practice This allows production of a consistent product as well as efficient reliable operation of the crusher Choke feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter particle crushing action
·The reduction ratio is driven by the Crusher Close Side Setting The actual minimum safe closed side setting of a crusher will vary somewhat for any given crushing machine depending upon the character of the material the amount of fines in the feed and whether the crusher is being operated under choke feed or regulated feed conditions It is
·Segregation in crusher hopper Fine Coarse Fine Coarse Segregation is the enemy of optimum crusher performance and operating costs Remember crushers operating under conditions as indicated above suffer from cyclic pressure peaks and cannot safely be operated at settings reasonable with a non segregated feed
·Choke feeding a cone crusher whereby a head of material is maintained in the chamber provides rock on rock breakage Evertsson 2000 Jacobson and Janssen 2010 studied the effect of varying cavity level inside a high speed cone crusher chamber in relation to capacity power utilization and size reduction properties
·The next consideration is correct presentation of feed to the crusher When possible the secondary crusher should be operated with a flooded crushing chamber referred to as choke feeding the crusher In a top performing crusher the head action at the top allows for a high rate of reduction as the material experiences its first
