3 Terms and Definitions
GB/T 7186 defined by the following terms and definitions apply to this document.
3.1
Feed rate speedoffeed
In performance testing process, to assess the amount of coal equipment, the unit is t/h per unit time.
4 Evaluation indicators
4.1 Evaluation of equipment re-election process performance indicators
Evaluation of equipment re-election process performance indicators total of six detailed indicators are as follows.
a) feed rate;
b) possible bias or imperfect degree;
c) Number of efficiency;
d) ash error;
e) total mismatch of content;
f) near the density of content.
4.1.1 feed rate
Throughout the performance testing process, as far as possible to maintain a uniform feed rate and feed rate was measured using the conventional method of precise, its single
Bit t/h.
4.1.2 may bias or imperfect degree
Possible bias generally used for heavy media separation, only the aqueous medium of imperfect separation. Their formula shown in Equation (1) and (2).
