In a concentrator that does not use a pendulum feeder or a belt scale, the amount of raw ore fed to the ball mill is usually measured by belt scraping. Specifically: a blade prepared in advance (wood, metals do), fixed length, typically 400 ~ 600mL, a certain time interval, such as 20min or 30min, scraped off with a scraper in the belt, the The scraped ore is packed in a container (strictly splashed), weighed, and the number is recorded. When scraping, care must be taken that all materials (including mud and water) within the length of the scraper are scraped off in the cross section of the belt. For slow belts with a slow speed (with a width of 650mm or less), scraping can be carried out without stopping the machine under the condition of ensuring scraping quality and safety; for wide belts with fast speed, it is necessary to stop for wide scraping quality and personal safety. Scrape. In order to ensure that the measurement is nearly accurate, when conditions permit, it is possible to scrape 2 to 3 segments at different points at a time, and perform weighing to obtain an arithmetic mean. The ore amount is calculated as follows:

Where Q is the amount of ore delivered per hour, t/h;

Q——the amount of scrape scraped once on average, kg;

L——the length of the scraper, m;

V——speed of belt conveyor, m/s;

f——The ore water content coefficient (usually 0.98, if there is more water, it needs to be measured).
