02-Jul-2012

 

How great would it be if tenants came to you pre-screened, so you only had to pick from a pool of the best renters? Unfortunately, you need to do the dirty work yourself, but there are ways to make the job easier. By letting renters know your requirements before they even contact you, you’ll help to naturally narrow down your pool of renters, leaving you only the most qualified. While this strategy isn’t fool-proof, it will raise red flags to renters who don’t reach your qualifications so they won’t waste their time working with you. Require the following items from renters early on to help you single out the best tenants:

Prescreening is to screen out the qualified grade material by the vibrating screen before the ore into the crushing section, which can be reduce the ore quantity entering the crusher and improve the production capacity of the crusher. At the same time, the prescreening can prevent powders by the rich ore. When dealing materials with high water content and powder, the wet powder can clog the crushing chamber of the crusher, which will significantly lower the production capacity of the crusher. The prescreening cam remove wet and fine slag in advance, which can offer a more normal working condition.

The application of the prescreening depends on the fine powder content in the ore. The higher the content, the better it is to adopt prescreening. When the specialty of the ore granularity is linear, the fine-grained content of which has exceeded the limit. No matter how big the crushing ratio of the crusher, the prescreening is always beneficial. In most cases, if the characteristic of the ore granularity is dished, it is economically worthwhile by prescreening. However, the height of the crusher plant will be lager by screening in advance, when the production capacity of coarse crusher is surplus, it should avoid the pre-screening. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like cement mill, Henan Hongxing is always doing the best in products and service.drum dryer:http://www.hxjqchina.com/product-list_35.html

The purpose of the check screening is to control the product granularity specification, which is good for improving the grinding efficiency. Because of the variety of crushing product there are a part of coarse particles larger than the discharging mouth width, such as when the short head cone crusher crushes the medium ore, the particle content of the discharging materials that the largest size is greater than the discharging mouth is 60%. It is different according to various crusher.

After the check screening, the unqualified products will sent for further crushing, which is good for improving the grinding efficiency. And the check screening can greatly improve the production capacity. However, although the check screening helps a lot it still add the investment and make the equipments of the crushing workshop complex, so it is generally only use the prescreening in the last crushing section and form a closed cycle check prescreening with the prescreening.
