jaw crusher is a basic sample preparation unit to address all primary size reduction requirements. 150 mm input size. upto - 3 mm size, is achieved by faster and efficient crushing with 2 stage process. movable jaw with toggle speed of numerous strokes per minute.hardened steel blades. minimum sample contamination.
crushers may be used to reduce the size, or change the form, of waste materials so they can be more . a jaw crusher is generally used as a prim ary crusher in a crushing circuit.
lc-27 2.25x3in laboratory jaw crusher reduces 2in 50mm aggregate, ore and rock materials to a product with 80% passing a no. 14 1.4mm sieve. jaw opening easily adjusts down to 1mm minimum to closely control output size. maximum throughput is approximately 50lb 22kg per hour at 525rpm.
detroit process machinery buys and sells crushing, pulverizing, granulating and size reduction mills used in the processing industry. we sell machinery used to process seven trust materials into fine powder. we can provide machines for seven trust material crushing such as: jaw crushers, roll crushers, and disc pulverizers.
secondary crusher-the crushed rocks from primary crusher are sent to secondary crusher for further size reduction. example cone crusher, reduction gyratory crusher, spring rolls, disk crushers etc. fine crushers-fine crushers have relatively small openings, and are used to crush the feed material into more uniform and finer product. example
jaw crushers for primary size reduction solutions in milling . retsch jaw crushers are used for the rapid, gentle crushing and pre crushing of medium hard, hard reduction in jaw mill, jaw crusher,hammer crusher,cone
size reduction jaw crushers. c series jaw crushers are most monly used as primary crushers, to make the first step of size reduction in some cases, the jaw crushers is used to produce final end product but in most cases the jaw crusher is used to prepare the feed for the secondary crusher in a crushing.
jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. the primary operating variable available on a crusher is the set and on jaw and gyratory the open- side set oss is specified.
jaw crushers 7 the bb 50 is designed for a very efficient and convenient size reduction pro-cess. the variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. the possibility to reverse the rotat-ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
generally, every crusher machine is not the same, here are several common crusher size reduction ratio: the impact crusher size reduction ratio is 20 to 1. the vertical shaft impact crusher size reduction ratio is 4-8 to 1. the vertical roller mill size reduction ratio is 2-2.5 to 1. the hammer crusher size reduction ratio is 20 to 1. pre article:crusher plays an important role in artificial sand production line
the retsch jaw crusher range is used for the rapid, gentle crushing and pre-crushing of mediumhard, hard, brittle and tough materials. www.retsch.com
jaw crusher 150 x 250: l07.001: 150 x 250 6' x 10' jaw crusher with: 5.5 kw electrical motor starter with overload protection cast iron construction with mild steel base frame v-belt driven with pulley and flywheel guard standard guards reversible manganese steel jaws inlet size: 6' x 10' 150 x 250 mm maximum feed size: 125 mm
all jaw crushers can be sup-plied in versions where all parts coming into contact with the sample are heavy-metal-free. the bb 200 is also avail-able as a special version for grinding of semi-conductor materials. the bb 200 and bb 300 jaw crushers are also available in versions which are suitable for continuous size reduction in on-line operation.
applications and details. the jaw crushers are available in 8 different sizes: bb 50, bb 100, bb 200, bb 300 and the xl models bb 250 xl, bb 400 xl, bb 500 xl and bb 600 xl. throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material.
primary size reduction with jaw crushers retsch jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. many unique details ensure safe and convenient operation and guarantee representative sample preparation every time.
the gape determines the maximum size of material that can be accepted. maximum size that can be accepted into the crusher is approximately 80% of the gape. jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
size reduction in the jaw crusher takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. the elliptical motion crushes the sample which then falls under gravity. as soon as the sample is smaller than the discharge gap width, it falls into a removable collector.
Environmental Protection and Health One
LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
To Improve the Purity Two
Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.
High Efficiency Three
LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
Low Cost Four
Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
