The double roller crusher is also known as a roll crusher or double teeth roll crusher This crusher is widely used in industries such as cement chemical electric power mining building materials and metallurgy for rough and intermediate crushing of brittle materials Product Features High Durability The rolls are made from wear
·Figure 1 Double roll crusher geometry Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4] [5] For rolls that have equal radii and length tangents drawn at the point of contact of the particle
·4 ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing Roll crushers have a theoretical MAXIMUM reduction ratio of 4 1 If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch
·Moreover petrographic analysis accelerated mortar bar test AMBT and miniature concrete prism test were conducted The results indicated differences in expansion for different crushers particularly in the AMBT where the expansion of aggregate Vitória was approximately fold higher when crushed with jaw crusher compared with roll crusher
·Crusher housing 2 Fly wheel 3 Base frame 4 Fixed roll 5 Floating roll 6 Hydraulic gap setting system Working principle Material is fed by a continuous feed arrangement into the middle of the machine between both rolls a The rolls operate at 5 m/s or even higher and shear and compression forces crush the material between the roll in the
Mining Machinery Supplier Roller Crusher Crusher Manufacturers/ Suppliers Zhejiang Chentai Machinery Manufacturing Co Ltd
The single roll crusher and tooth double roll crusher manufactured in China is the classic primary grinder with the maximum feed granularity up to 800 1000mm While the WMS roll crusher manufactured in Germany is used for fine crushing and rough grinding work
·Such rolls are used mainly for coarse crushing ; that is they take the product from the jaw or the gyratory crusher from to in in size and reduce it to about in where the ore requirements demand a maximum granulating effect and a minimum pulverizing or sliming effect upon the crushed product have made little progress
