In this specific embodiment, which is mainly used for the coal sample sample preparation stage, needs first by coal sample
3mm is crushed to, then division goes out file for reference coal sample and the coal sampling of 3mm.
Wherein, batcher 1 be used for by coal sample from acquisition zone or from the exit of a upper coal sample Preparation equipment transport to
The feed inlet of crusher 2, in order to crush coal sample, mechanization transportation contributes to the labor intensity of mitigation personnel.Usual batcher 1
Select Z-type elevator, naturally it is also possible to be the batcher of belt feeder, screw(-type) feeder, rotary feeder or other forms.
The feed inlet of crusher 2 is connected with the discharge port of batcher 1, while the discharge port of crusher 2 and fairing 3
Feed inlet is connected, and is mainly used for coal sample reduction.Broken purpose is mainly to increase the granule number of coal sample, reduces reduction error.By
6mm (or 13mm), 3mm, 0.2mm sample preparation stage are generally comprised in the preparation of coal sample, wherein, 6mm (13mm) stages prepare full water
Divide coal sample, the 3mm stages prepare coal sample of filing for reference, and the 0.2mm stages prepare general analysis sample, therefore the crumbling method of crusher is also classified into out
Coarse crushing that material granularity is 25mm~6mm, discharging-material size are that broken in 3mm~1mm and discharging-material size is in small, broken bits less than 0.2mm.Accordingly
Ground, the crusher type for coarse crushing include jaw crusher and hammer mill, and broken crusher type includes hammer in being used for
Formula crusher and double-roll crusher, include disc mill and closed crushing machine for crusher type in small, broken bits.In coal
In sample preparation flow, when a kind of coal sample of granularity of division, it need to ensure the discharging-material size of selected crusher and selected reduction device
Division granularity it is consistent.In this specific embodiment, prepared by the coal sample for being mainly used for 3mm due to the equipment, therefore select broken
Broken machine is specially 3mm double-roll crushers.It is of course also possible to be the crusher of other forms, but it must assure that its discharging-material size should
It is consistent with division granularity.
