Regulators are used on the compressor itself  Air compressors are used in industrial, commercial, and home workshop environments to perform an assortment of jobs including blowing things clean; running air powered tools; and inflating things like tires, balls, etc. Regulators are used on the compressor itself to ensure that the tank pressure gauge manufacturers never reaches unsafe levels and to allow the user to adjust the pressure coming out of the tank to match what is needed for the task. Often, when one large compressor is used to supply compressed air for multiple uses (often referred to as "shop air" if built as a permanent installation of pipes throughout a building), numerous additional regulators will be used to ensure that each separate tool or function receives the appropriate pressure it needs. This is important because some air tools, or uses for compressed air, require pressures that may cause damage to tools or materials in other cases. Water pressure reduction Often, water enters water-using appliances at fluctuating pressures, especially in remote locations, and industrial settings. This pressure often needs to be kept within a range to avoid damage to appliances, or accidents involving burst pipes/conduits. A single-stage regulator is sufficient in accuracy due to the high error tolerance of most such appliances. Oxy-fuel welding and cutting Oxy-fuel welding and cutting processes require gases at specific pressures, and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding. Oxy-gas regulators usually have two stages: The first stage of the regulator releases the gas at a constant rate from the cylinder despite the pressure in the cylinder becoming less as the gas is released. The second stage of the regulator controls the pressure reduction from the intermediate pressure to low pressure. It is constant flow. The valve assembly has two pressure gauges, one indicating cylinder pressure, the other indicating hose pressure. Propane/LP Gas All propane and LP Gas applications require the use of a regulator. Because pressure gauge suppliers in propane tanks can fluctuate significantly, regulators must be present to deliver a steady flow pressure to downstream appliances. These regulators normally compensate for tank pressures between 30 - 200psig and commonly deliver 11 inches water column (0.4 psig) for residential applications and 35 inches of water column (1.3 psig) for industrial applications. Propane regulators differ in size and shape, delivery pressure and adjust-ability but are uniform in their purpose to deliver a constant outlet pressure for downstream requirements. As is the case in all regulators, outlet pressure is lower than inlet pressure. Recreational vehicles For recreational vehicles with plumbing, a pressure regulator is a necessity. When camping, a source of water may have an enormous pressure level, particularly if it comes from a tank that is at a much higher elevation than the campground. Water pressure is dependent on how far the water must fall. Without a pressure regulator, the intense pressure encountered at some campgrounds in mountainous areas may be enough to burst the camper's water pipes or unseat the plumbing joints, causing flooding. Pressure regulators for this purpose are typically sold as small screw-on accessories that fit inline with the hoses used to connect an RV to the water supply, which are almost always screw-thread-compatible with the common garden hose. Breathable air supply Main article: Diving regulator Pressure regulators are used with air tanks for SCUBA diving. The tank may contain pressures well in excess of 2,000psig, which could cause a fatal barotrauma injury to a person breathing it directly. A regulator allows only a sustained flow of air at the ambient pressure (which varies by depth in the water). Mining Industry As the capsule pressure gauge builds rapidly in relation to depth, underground mining operations require a fairly complex water system with pressure reducing valves. These devices must be installed at a certain distance interval, usually 600 feet (180 m).[citation needed] Without such valves, pipes would easily burst and pressure would be too great for equipment operation. Oil and Gas Industry

The Problem: The Challenges of Having to use Hydraulic Fluid in a gas pipeline
Todd has to pressure calibration equipment multiple chart recorders on a gas pipeline but he has several concerns. Since it is a natural gas pipeline and it is the middle of winter, he is concerned about using hydraulic fluid to do the calibration. His concerns include:
?Contamination: Because Todd has to use a liquid to calibrate a gas pipeline, there may be some residual fluid left over that that could create a false differential pressure
?Damage to the chart recorder: Because is winter, this residual fluid in the sensing element could freeze and damage the chart recorder
?Pressure Stability: Hydraulic fluid is less stable because it is incompressible and cannot expand to accommodate any fluctuations in volume
The Solution: A Ralston Instruments Calibration Manifold
A colleague told Todd about Ralston Instruments calibration manifolds. He is interested in this option because the manifolds use compressed nitrogen gas instead of hydraulic fluid. This feature helps to remedy Todd's concerns because compressed nitrogen eliminates the risk of residual fluid contamination and will not freeze causing damage to the chart recorder. Moreover, unlike hydraulic fluid, compressed nitrogen is very stable because of its ability to expand to fill the test volume. Todd also likes that the Ralston pressure calibrator manifolds come complete with low volume hoses and quick-connect adapters that help to make setup easy and limits the amount of gas that is used with each calibration.
The New Configuration
Todd connects a quick-connect to the pressure calibrator manufacturer on his nitrogen bottle, one to the high side of the chart recorders and one on his pressure reference gauge. He uses the valves and fine adjustment control piston on the calibration manifold to dial in each of the test pressure points quickly and accurately. He is especially pleased that the calibration did not waste very much nitrogen since he was using the Ralston micro-bore hoses. He decides to use this calibration manifold from now on when doing static calibration of chart recorders and pressure transmitters.

Crushed aggregate is a combination of stone, gravel, sand, and slag, used in the construction of homes, infrastructure, spring cone crusher manufacturer businesses, and roads. Crushed aggregate is made from natural raw materials and making it involves the use of several heavy machines. Once the process is finished, the result is crushed aggregate, a material the construction industry can't do without.
The Jaw Crusher
Large rocks are mined from gravel pits or quarries and transported to the surface, where they are usually placed in dump trucks. Once on top, the rocks are sifted for smaller pieces and debris with the aid of a powerful vibrating conveyor belt. The conveyor belt transports the materials to the jaw crusher, which is really the first step in aggregate crushing. The jaw crusher is made of two plates, rather like a human mouth. It crushes the rock between the two plates and then "swallows" it, pouring it out onto another conveyor belt, which takes it to an impact crusher.
The Impact Crusher
An spring cone crusher flings the rocks against hard plates, causing them to split and break into much smaller pieces. They're then put on a vibrating screen, which acts as a large filter through which the crushed aggregate is sorted by size. The finer the aggregate needed, the more it gets filtered; this allows quarries to sell different types of crushed aggregate to customers, based on the project at hand.
Dump Trucks
Crushed aggregate is then transported to the work site by dump trucks. Most crushed aggregate is produced within forty miles of where it's used, though longer distances are not unheard of, and about ninety percent of it is transported by dump trucks.
Other Machines
Of course, there are many other machines involved in aggregate crushing. The hydraulic cone crusher is good for crushing rocks into medium, fine, or super-fine grade aggregate, and can be adjusted according to what the customer needs. A spring cone crusher is used for rocks of medium-to-hard hardness levels, and has a variable-sized crushing chamber. A sand-maker crushes rock, including metal ores, into extremely fine aggregates, while a drying hammer crusher is a floor-to-ceiling machine that specializes in soft or moist raw materials. Finally, a ring hammer crusher specializes in both moist and dry aggregates, and pounds them down to size with a series of hammers.
Aggregate crushing is a long, laborious process, involving a number of stages and several pieces of heavy machinery. Regardless, crushed aggregate is a necessary component of almost any Mobile VSI Crusher project.
