Abstract

The invention discloses an iron ore sampling and sample making method, which comprises the following steps of: 1) sampling; 2) crushing: crushing the samples taken in the first step; 3) splitting: inputting the taken samples crushed in the second step into a splitting machine to be split; and 4) indoor sample making. The invention also discloses an iron ore sampling and sample making system, which comprises an ore feeding hopper, wherein a first belt conveyor corresponding to the ore feeding hopper is arranged at the lower part of the ore feeding hopper, the tail end of the first belt conveyor corresponds to a crude crushing machine, a material outlet of the crude crushing machine is connected with a fine crushing machine through a second belt conveyor, and the fine crushing machine is connected with the splitting machine through a third belt conveyor. The defects of a spooning method and a well digging method are fundamentally overcome by a reverse shoveling digging machine sampling method, and in addition, the method has the advantages that the sampling speed is high, the sample quantity is large, and the representativeness is high. Through production test and through the verification, analysis and comparison in various aspects, the system is used for carrying out large-batch sampling and sample making on large-block materials and outsourcing ores, and the samples which really reflect general materials can be obtained.

Description

technical field

[0001] The invention relates to an iron ore sampling method and system. Background technique

[0002] The applicant purchases a relatively large amount of iron ore every year. The lumpiness of iron ore is between 0 and 350mm. The most critical part of purchasing iron ore is to test the iron grade and related quality indicators of the iron ore. The detection accuracy is directly related to the economic benefits of the purchased iron ore.

[0003] The more important link in the detection process is to take samples from many items. Sampling is the process of taking out a small part of the material from a large number of materials in a scientific way. This small portion of materials can represent the raw materials both in nature and in composition.

[0004] Existing equipment can only meet small samples with relatively small particles, which cannot meet the existing needs. At present, manual division is generally used, which has poor uniformity, high labor i...

Embodiment Construction

[0111] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0112] Such as figure 1 Shown, a kind of iron ore gets sample preparation method, comprises the following steps:

[0113] 1) Sampling;

[0114] 2) broken, the sampling of step 1) is broken;

[0115] 3) shrinkage, step 2) broken sampling input shrinkage machine 4 shrinkage processing;

[0116] 4) Indoor sample preparation.

[0117] The sampling of described step 1) adopts crawler-type backhoe excavator sampling, and the width of sampling bucket mouth is 1 meter, and the depth of bucket is 1 meter, has guaranteed that 350~0 millimeter material is taken up, both can according to need in length Dots can be distributed in the direction of the thickness, and can be dug in the thickness direction as needed until the bottom of the material is dug; the samples are taken out and put into the car containing the ore samples.

[0118]The sampling sample broken ...
