·Among his findings were empirical models showing that crusher setting feed size crusher speed and throw affects particle shape in products from cone crushers Increased average feed size increases flakiness index likewise does decreased crusher speed Further Bengtsson states that in full scale crushing there is no evidence that feed shape

The impact force occurs as the material enters the crusher and is impacted by the rotating roll Shear and compression forces occur as the feed material is pulled between the crushing plate and/or crushing rolls Depending on the feed size material is fed into the crushing chamber and encounters a single or a pair of rotating rolls
Easily ensures the desired crushed particle size Suitable for fine crushing More suited for fine crushing than top feed type Uniform particle size The grate bar minimizes the effects of raw stone size and shape on the crushed particle size Extremely high reduction ratio

·Feed size was divided into two fractions of −4 and 2 − millimeters from which different feeds with different weight and size percent values were fed to mill at three feeds of
·Where a product size is required below that of the feed size it is usual to operate the crusher in closed circuit with a screen of appropriate size and adequate capacity However the crusher can be operated in open circuit • Typical net production of 5mm product from 5 35mm feed Result 53 tph 5mm product STANDARD SPEED
Maximum Feed Size [mm] Rotor Size D x W [mm] Weight [kg] HRC 0505 200 250 x 530 225 520 x 510 HRC 0507 Roll Crusher operation is based on the principle of continuous pressure generated between two counter rotating rolls; allowing uninterrupted crushing in contrast to the intermittent action of jaw crushers
·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
In this study the effects of three different choke feed level 1/1 1/2 and 1/4 and four different effective reduction ratios 5 10 and 20 depend on the capacity of the crusher of the
·may get stuck in the feed opening of a cone crusher thus blocking other material from entering the cavity The big feed opening and lifted spider arms of the GP Secondary cone crusher help by enabling smooth flow of even the coarsest feed material by preventing the formation of blockages This unique feed opening to weight ratio creates

·Feed Size Jaw crusher can accept large limestone lumps or rocks as feed sizes ranging from 1000 1200mm depending on the crusher model This eliminates prior size reduction steps Output Size The coarse reduction ratio of 6 1 produces output ranging from 60 100mm which is suitable as feed for secondary cone or impact crushers
Extra coarse concave max feed size 195mm check lead time ¹ NOTE NOT RECOMMENDED TO BE USED WITH PRE SCREEN SYSTEM Coarse concave max feed size 175mm check lead time ¹ Sand concave max feed size 63mm check lead time ¹ RECOMMENDED TO TAKE SHORT THROW ECCENTRIC OPTION Short throw eccentric check lead time ¹
·Feed Opening Looking at the cone crusher diagram above the feed opening is the first aspect of the machine The feed opening is where the raw material feeds into the crusher Even the largest cone crushers are limited by the size of their feed opening as they can only accommodate pieces of rock or substrate that will fit inside the machine
Versatile The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and higher It is less sensitive to wet and sticky material than RollSizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks
·Feed the crusher slowly for one or two days until the cast wear surfaces have been worn smooth the feed at Full Rate LMC50 JAW CRUSHER End fineness < 1 5mm depending on material size and characteristics End fineness setting 1 5 15mm Capacity 50kg/u depending on material size and characteristics

Figure is a typical set up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm
