Artificial sampler what
The scene of the artificial sampler is varied, but mainly sampling spoon,HCS90 cone crusher in India sampling pot, sampling. Etc.
In order to ensure the accuracy of the sampling, sand washing machine in India sampling must obey the following:
1) sampling spoon the width of the mouth, at least in the specimen should be the biggest particle 4, 5 times.
2) sampling box should have smooth wall, and easy to dump.
3) sampling, should make sampling spoon cross-sectional pulp flow, and should be the constant flow through the pulp.
4) sampling time interval must be the same.
5) sampling box after dumping,wet pan mill rinse with water, rinse water and pour into in the specimen.
6) each a sampling point should have special sampling box.
Sample processing steps what
Take the original samples, carry on the processing to inspection. Processing steps include the crushing, blending and classified. If the sample after screening out, to keep original requirements must be the grain size composition, it needn't broken, just blending and points can.
The broken adopting laboratory with crusher or grinding machine. The aim is to put the samples were mixing, can use ring cone method, first to sample of the cone into, and then PingCheng garden ring, again will garden ring into garden of cone, repeatedly mix two or three times can.
Classified is will sample quantity reduction, will have the samples were spread out on four differentiator or two differentiator classified until requirements so far.
How to determine the minimum weight
In order to make some of the sample is truly representative samples, can reflect the overall in the ore various component content, mineral composition, chemical composition and physical properties, such as, to determine the not destroy the sample accuracy, weight and the minimum weight but samples.
Sample the minimum weight, the main materials and the largest size, mineral disseminated characteristics and the grade of ore has close relationship. Normally available next type calculation:
Type: Q-sample weight, kg;
D-largest size in the specimen, centimeters;
K-and ore properties related coefficient, generally 0.01 0.2.
The needs of the sample weight, and sampling purpose has close relationship. Such as chemical analysis and tries gold analysis of the sample weight, general 10, 500 grams (including, vice sample); Screening for 25 g sample chromatography (ore size in the 0.1 mm below) to 20 kg (ore grain size of 20 mm); For optional sex research sample by the hundreds of kg to several tons.
