Description

A kind of multi-stage screening crusher
Technical field
The present invention relates to crushing plant technical field more particularly to a kind of multi-stage screening crushers.
Background technique
In hard ore, building aggregate are broken, crusher is often used.It needs before crusher broken material to material It is sieved.
Therefore the screening of material and crushing operation, are completed by two procedures, two kinds of process equipments.Usually first pass through The block material that screening machine will be crushed, which is sifted out, to be come, and is then machined to required granularity by broken again.Screening machine used There are gravity flow screen, vibrating screen, probability screen and roller picker.
Crusher has jaw, toothed roller type, reaction type and hammer mill.These screenings and crushing mechanism are in actual production All there is different advantage and disadvantage in operation.From sieve, in terms of broken process flow for, due to the intrinsic factor of equipment, outmoded aging Bring dust, noise all to exceed environmental requirement to actual production, especially foundation of civil work investment, the installation of equipment, using and Maintenance, labor intensity of workers, energy consumption and operating environment pollution aspect are all to compare distinct issues.Further, since being twice Process causes continuous production poor, influences production efficiency and yield.
Publication No. CN 102580814A, publication date are that on 07 18th, 2012 Chinese patent literatures disclose one kind Sieving approach all-in-one machine, it includes rack, it is characterised in that: it is equipped with two vertical-spindle hammer crushers on the rack, it is broken in two vertical shafts The top of broken machine is equipped with winnowing type screening machine, and the composition of winnowing type screening machine includes material screening hollow cavity, in material screening Mixed material feed inlet is equipped with above hollow cavity, being respectively arranged on the left side and the right side air inlet and going out in material screening hollow cavity Air port, in the rough material outlet of material screening hollow cavity being respectively arranged below with and thin material outlet, rough material outlet is located at Below mixed material feed inlet, thin material outlet is located at the direction of air outlet side of rough material outlet, and rough material outlet and carefully Feed inlet connection of the material outlet respectively at two vertical-spindle hammer crushers.
