The belt scraper is a thin metal or rubber plate, measuring the width of the conveyor belt, that is used to remove material that has attached to the belt. Belt Scrapers are used on top and/or bottom of a belt depending on the type of material being screened.
Sometimes referred to as a wear plate, is a wear-resistant sheet steel. It is manufactured and exported worldwide by the Swedish company SSAB, which developed the first modern wear-resistant sheet in 1974. This steel wears very slowly, even when under large mechanical load.
Luffing is the angle that the stacking conveyor is placed at, which then determines the dimensions of the stockpile that is being made. Depending on the type of material being screened, the pile may need to be at a lower angle. An example of this would be if you were stacking a very fine material like sand, its luffing angle will be smaller than a compost pile.
Polyurethane wear plates are used in areas of a machine, such as the inside of the hopper and conveyor side walls, where material passes and creates abrasion. These wear plates vary in thickness and slow the rate at which the machine parts wear.
A radial conveyor is a conveyor, that when set in place, can rotate 180°. This is very helpful for any size production to maximize uptime of machine and minimize the need for repositioning the machine once a stockpile gets to a certain height.
A side skirt helps prevent spillage of the product and reduce contamination under the conveyor belt. It consists of an aluminium enclosure with a strip of polyurethane wear plates to reduce the damage done to the machine.
A stacking conveyor is a type of machine that carries already processed material up a conveyor belt into a stockpile. There are different types, heights and angles for these conveyors, depending on what application it is being used for.
Tier II (Tier 2), is an engine emissions standard. There are several tiers of emissions standards that large diesel engines must adhere to by certain dates.
Tier II engines have more advanced technology than Tier I which reduces the amount of nitrogenous emissions from the engine. Tier II was implemented from 2001-2003 and was the current standard until 2005.
Tier III (Tier 3), is an engine emissions standard. There are several tiers of emissions standards that large diesel engines must adhere to by certain dates.
Tier III engines have more advanced technology than Tier II which reduces the amount of nitrogenous emissions from the engine. Tier III was implemented from 2005-2006 and was the standard until the interim Tier IV was implemented in 2011 and the final Tier IV requirement was implemented in 2014.
Tier IV (Tier 4), is an engine emissions standard. There are several tiers of emissions standards that large diesel engines must adhere to by certain dates.
Tier IV engines have exhaust after treatment systems to reduce emissions of particulate matter (soot) and nitrogenous compounds. This EPA mandate significantly reduces smog and other pollutants from diesel machinery.
