Measure inside big and material particles and micro-crack be present, these features are advantageous to follow-up grinding operation.Therefore, high pressure roller mill at present
Technology is widely used in the work flow in small, broken bits in ore dressing plant.It is closed circuit by high pressure roller mill in magnetite separation factory
The through-screen size of screening can be controlled in 0-3mm, and this part undersize can get rid of 20- after the pre- magnetic separation whipping of coarse grain
30% non magnetic ore, the treating capacity of follow-up ore grinding can be substantially reduced, realize much broken and lessmill, it is energy-saving.
The current equipment Layout Problem about handling high pressure roller mill product, i.e. screening-magnetic separation-ore grinding-magnetic dressing process equipment
The reality of arrangement is：All magnetic concentration workings and grinding operation are all placed in a main building by most ore dressing plants, and large-scale
Ore dressing plant often magnetic concentration working and grinding operation respectively account for main building one across, referred to as magnetic separation across with ore grinding across.High pressure roller mill is closed circuit
The pre- magnetic separation of undersize coarse grain of screening is all magnetic concentration workings before grinding operation after screening operation from flow
First paragraph operation.Relatively other magnetic concentration workings, its coarse size gravity flow gradient is big, if the pre- magnetic concentration working of coarse grain is placed in magnetic separation
Across, then in order to meet the gravity flow of its ore pulp, the general operation be respectively positioned on magnetic separation across highest point, raised overall magnetic separation across height
Degree；In addition magnetic separation across screening across and surge bunker between also by ore grinding across separating, add the pumping of the pre- magnetic concentration working of coarse grain
Distance, add energy consumption.
Therefore, it is smooth to develop a kind of flow, equipment connection and reasonable arrangement is energy-saving, it is not necessary to increases magnetic separation across height
Screening-magnetic separation-ore grinding-magnetic plant arrangement system is necessary.
The content of the invention
It is an object of the invention to provide a kind of flow is smooth, equipment connection and reasonable arrangement is energy-saving and need not increase magnetic separation
Across screening-magnetic separation-ore grinding-magnetic dressing process equipment arrangement system of height.
The purpose of the present invention is realized by following technical proposals：
The present invention a kind of screening-magnetic separation-ore grinding-magnetic dressing process equipment arrangement system, including basic platform, screening across, buffering
Storehouse across, ore grinding across, the surge bunker positioned at surge bunker span centre top, the surge bunker platform below surge bunker, positioned at surge bunker
Lower section and be arranged on surge bunker platform ribbon conveyer, screening is shaken across interior below ribbon conveyer driving wheel end
Dynamic sieve, positioned at ore grinding across one section of ball mill on interior basic platform and its charging gear, one section of cyclone group feed pump, one section of rotation
Device group, a stages of magnetic separation are flowed to ore deposit pulp distributer, a stage magnetic separator, the pre- magnetic concentration slurry distributor of coarse grain and coarse grain pre-selection magnetic separation
Machine, described screening across, surge bunker across with ore grinding across being arranged in parallel and be sequentially connected, it is characterised in that：The pre- magnetic separation of coarse grain
After the tail wheel of ribbon conveyer being sequentially arranged in ore deposit pulp distributer, one section of low intensity magnetic separation pulp distributer and one section of cyclone group
On the surge bunker platform of side；Surge bunker across surge bunker platform below set magnetic concentration working platform, on magnetic concentration working platform
It is sequentially arranged the described coarse grain pre-selection stage magnetic separator 13 of magnetic separator 8 and one.
The ore deposit pump pond 5 in the case where being provided with sieve below described vibratory sieve on basic platform.
Described surge bunker across basic platform on be provided with sieve under ore deposit pump, by connecting pipe with sieve descend ore deposit pump pond 5 connect
Connect, installation and repairing electric block 7 is provided with ore deposit pump correspondence position under sieve below magnetic concentration working platform.
It is an advantage of the invention that：
1）Surge bunker across surge bunker platform below set magnetic concentration working platform, the pre- magnetic concentration working of coarse grain and a weak magnetic are elected to be
Industry is arranged at magnetic concentration working platform, takes full advantage of the originally existing clearance spaces of surge bunker bottom, and magnetic separation is not required to individually set
Across arrangement, main building, across forming, greatly reduces capital expenditure only by ore grinding；
2）The pre- magnetic separation of coarse grain is given to ore deposit pulp distributer, one section of low intensity magnetic separation pulp distributer and one section of cyclone group and vibratory sieve
Material belt type conveyer shares surge bunker platform, takes full advantage of the free space at ribbon conveyer rear, reduce further base
Build up this；
3）Magnetic separator and cyclone are arranged in surge bunker across, not only integral device characteristics of compact layout, and equipment room connecting line away from
From shortening, the discrepancy in elevation needed for pulp gravity flow is reduced, reduces the discrepancy in elevation of integral device arrangement and the pumping of ore pulp that needs pump
Energy consumption.The arrangement and screening-magnetic separation-ore grinding-magnetic dressing process of whole system move towards basically identical, and flow is more smooth.
