The process of construction, mining or quarry workers breaking down huge stones can be detailed. Many of these efforts rely on the presence of jaw crushers , machines whose design specifications allow for such a laborious and essential feat.
Identification
jaw crushers are a powerful tool for crushing stone or rock. The specifications will differ depending on what type of crusher you are using. One of the primary considerations in the construction of jaw crushers is the metal used for the crushing mechanism. It has to possess a breaking point that is considerably higher than the stone or rock it is attempting to break down.
Basic Design Specs
In order for a jaw crusher to work correctly, the crusher must have two primary metal pieces. One of these does’t move or is “stationary.” The other progresses inward against that piece in order to crush the stone. This allows the jaw crusher to use both “attrition and compression” to achieve its goal. Two common varieties of crusher include deep and shallow bodied types, the former being designed for greater “rock on rock” crushing.
Reduction Ratio
The jaw crusher operates on the principle located in a reduction ratio. In other words, there needs to be a specific balance between the space of the crushing area and the load or amount of material introduced into it. Jaw crushers demand a general specification of a 6 to 1 reduction ratio.
Jaw crushers are used in quarries, construction sites and other similar applications to break down large pieces of rock. They are commonly the first step in the reduction process, breaking large rocks into smaller pieces that will be transported or further reduced. Rocks are poured into an opening and funneled between two rigid pieces of metal that are repeatedly compressed to crush the material to bits. Common jaw crusher specifications describe size and capacity.
feeder Opening
Feeder opening specifications on a jaw crusher describe the dimensions of the slot into which materials for crushing are fed. This measurement is usually expressed in millimeters. Feeder opening specifications vary from company to company. Some manufacturers produce jaw crushers with feeder opening measurements contingent on the size of the individual unit. Other manufacturers endow every crusher with the same size opening. Such companies differentiate units rather than differentiating by capacity and overall size. American and British companies generally express feeder opening measurements in both inches and millimeters.
Maximum Feeding Size
Maximum feeding size specifications describe the largest object a jaw crusher is capable of reducing. This specification is important particularly for companies that produce a host of crushers with varying capabilities that have the same feeder opening measurements. You can easily assume that a unit can duly crush any material that will fit through the feeder opening. However, this is not the case. Rather, maximum feeding size specifications are based on the starting distance between the two rigid pieces of metal that do the crushing and the compression power a unit is capable of generating. Maximum feeding size is commonly expressed in millimeters.
Capacity
Jaw crusher capacity specifications express how many tons of material a unit is capable of processing per hour. Companies based in countries that use the metric system automatically list this specification in metric tons per hour. Companies based in countries such as the U.S. or Australia that do not use the metric system express this specification in both short and metric tons. A short ton is the common American ton, or 2000 lbs. The metric ton is the equivalent of approximately 1.1 short tons, or 2200 lbs.
Engine Power
Engine power describes exactly that. This measurement is expressed either in horsepower — in countries employing the British system, or in kilowatts — in countries employing the metric system. The capacity of a jaw crusher is contingent upon the power of the engine as it is the engine that provides the energy requisite for continued crushing. Maximum feeding size is also directly related to engine power specifications, as a crusher’s ability to reduce material is contingent upon the power an engine is capable of producing.
