Factors affecting emissions that are common to most operations include moisture content in the rock, type of rock processed, type of equipment, and operating practices employed. These factors apply to both process (primary) sources and fugitive (secondary) sources in quarry and plant operations.
Depending on geographic and climatic conditions, the inherent moisture content or wetness of quarried rock may range from nearly zero percent to several percent. The effect of moisture content is especially important during quarrying, material handling, and initial plant operations such as primary crushing.
Surface wetness causes fine particles to agglomerate or adhere to the faces of larger stones, resulting in a dust suppression effect. However, as new fine particles are created by crushing and attrition and since moisture content is reduced by evaporation, this suppressive effect diminishes in later stages.
The type of rock processed is also important. Soft rock produces a higher percentage of fines than do hard rocks because they are more friable. Therefore, processing of soft rocks has greater potential for emissions.
The type of equipment and operating practices employed also affect uncontrolled emissions. Equipment selection is based on a variety of parameters, including quarry characteristics, rock type processed, and desired end products. Emissions from process equipment such as crushers, screens and conveyors are generally a function of the size distribution of the material, and the amount of mechanically induced velocity imparted to it.

Gold mining is a hobby for many and a career for some. Whether you want to mine gold for fun or serious income you still need to invest in certain pieces of equipment particular to the mining business, and you should not hit the road for gold and glory before you have all the most important tools.
Before you can begin to process the gold you need to find the gold. Metal detecting machines in the 21st century, according to Steve Herschbach at akmining.com, “can detect gold as small as a half a grain with ease. The depth of detection grows with the size of the target,” and “only the largest nuggets will be found at depths over a foot.” Metal detectors range in price from hundreds to thousands of dollars, but you can find detectors at yard sales and auctions for much less, or you can learn to build the metal-finding devices.
Sluice boxes are narrow boxes used to filter the gold. Original sluice boxes, according to keenengineering.com, “were lined with raised obstructions that were placed in a vertical position to the flow of the current. The flow of water carried the material down the length of the box” and the heavier sediment (and hopefully gold) quickly sank to the bottom as the water and lighter material flowed through the box. Original sluices were made from lumber and logs, but modern sluices are made from light-weight metals and are very portable. You can buy a sluice box for under $100, or you can make your own.
Original gold miners could not penetrate deep waters, but over time they began to build machines to do what they could not. Dredging machines, old and new, perform similar functions, sucking the sediment from lake and river beds and then running the particles through a sluice. There are three types of gold dredge: the surface dredge, the submersible dredging tube and the underwater submersible dredge. Each type of dredge has a system to suck and filter underwater materials, but underwater dredges are more complicated, more expensive and require more maintenance. According to keenengineering.com, “A small portable backpack dredge of today can weigh as little as 40 pounds and cost around eight hundred dollars.”

When formulating air pollution control regulation, it was considered a must to consider the aspect of enforcing that regulation. A regulation may be set for a specific operation, a combination of operations, or the entire processing or manufacturing facility.
From a compliance evaluation point of view, USEPA has separate standards for each affected operation in the industry. In practice however, it often may be difficult to do so. The enforcement aspects of regulations for alternative air pollution control methods are discussed below.
The stone crusher industry is characterised by a number of separate processing operations and emission sources, a variety of equipment types and configurations, and feed rate and composition variations. Some of the particulate emission sources such as quarrying, dumping and storage are open sources.
Other operations such as conveying and loading are frequently only partially enclosed, while crushing and screening are more completely enclosed. In addition, the moisture content of the stone has a great effect on the particulate emissions. Process feed rates are not generally measured and some of the individual processes may operate on a very intermittent basis.
The process parameters that should be monitored to ensure that facilities are operated normally during enforcement tests or inspections include, the process production rate, the moisture content of the feed material and the approximate size distribution of the raw material and product but generally stone crushers are not equipped with devices for measuring process weight rates.
An analysis of moisture content is important to ensure that dust control at the time of the test is effected by the control system and not the result of unusually high moisture levels that are not normal for the plant. When the addition of moisture is part of the control system (wet dust suppression), a record should be kept of the amount of added moisture required to effectively control emissions under the worst operating and climatic conditions. Moisture would have to be determined by taking samples of the feed streams for subsequent analysis.
Air pollution regulations for the stone crusher industry can be expressed in terms of
(1) Quantitative particulate emission limits in terms of concentration, mass rate or process weight type units,
(2) Limits on visible emissions,
(3) Ambient air concentrations at the plant property line,
(4) Equipment standards that include specifications on process and/or control equipments, operating conditions and monitoring requirements, and
(5) Compatible combinations of such measures.
The quantitative emission limits based on measured concentrations could be applied to the enclosed sources such as crusher or screen. Determination of particulate emission concentrations where control devices are used requires a source test on the exhaust of each control device as per USEPA methods.
At times more than one process may be vented to a common control device and only the total emissions from the connected processes need to be determined. For open sources such as drilling, open conveying and storage, quantitative emission limits are not applicable since there is no accurate method of measurement.
The enforcement of visible emission limits in terms of opacity or as a percent of time when emissions are visible is a feasible approach and is especially useful for fugitive sources of particulates and open processes that are controlled by wet dust suppression. Visible emission limits can also be applied to enclosed sources and used in conjunction with a quantitative emission limits or as a single limit.
The visible emission determinations can be made with established procedures as per EPA method 9 by a single trained and certified observer. The readings can be taken in one or two days and usually not during night time or during very inclement weather conditions.

In some crushers the crushing equipment’s (primary or secondary) are enclosed inside a big shed. The shed is closed from 3 sides and top but leaving the front end completely open. This type of shed cannot stop wind currents carry the emission away from the crusher and therefore such enclosure does not serve any useful purpose unless enclosed from all sides.
The constraints were reported in completely enclosing the shed such as during maintenance it is required to take out large components using cranes, loaders etc and this becomes difficult if the front access is closed. The general practice is to remove some sheets from the enclosure to create an opening to take out material during repairs. These removed sheets never get replaced again anticipating the occurrence of the similar problem again. This ultimately results into partial enclosures
At the discharge of screen and crushers some stones spill over from the belt conveyor and get accumulated on the floor. This spilled over material needs to be periodically removed or else the piled up material beyond the height of the system drive component may hamper the operation of the belt conveyors etc.
Such spillages are so frequent and large in quantity that almost once in a day it needs to be cleaned. This spilled material also contains large quantity of stone dust. It is due to this reason, in order to provide easy access for removal of material, one side of the enclosure is generally left open or even if a door is installed it always remains in open condition.
Such spillages happen due to systems faults or design lacunae such as misalignment and improper angles of discharge and belt conveyors, use of locally available material like used truck tyre tread pieces joined together to form the belt conveyor, lack of provision of rubber skirting etc. The possible solution to overcome this problem could be to provide well designed layout, proper/standard belt conveyor material, rubber skirting on the side of the belts, proper alignment and angle of the crusher discharge chute and belt conveyor etc.
The product spillages also occur due to holes formed in the discharge chute of crushers and screens at the point of free fall of stones as the steel plate gets punctured due to wear and tear and eventually gives way for spillages. This could be minimized by adopting a step wise design of the chutes to reduce free fall height or by strengthening the steel at the point of impact. In the step design, a layer of stones always remains above the steps and the free fall impact is taken by these accumulated stones which saves the steel from direct wear and tear and increases its life.
Some crushers use Jute Cloth in place of GI steel sheets as material of construction for enclosures to reduce the cost. But wind current can pass through jute cloth enclosure thereby reducing the usefulness of the enclosure in terms of containment of dust. At times plastic/PVC sheets are used for enclosure especially for the belt conveyors and vibratory screens but it gets torned frequently due to high velocity wind currents and therefore not effective enclosures.
Many units provide an enclosed hopper for collection and storage of less than 6mm size dust product, but a large opening is kept at the point of discharge from belt conveyor in to the hopper and fine dust escapes through this opening. To achieve effective containment the belt discharge opening should be kept closed as much as possible by providing rubber flab type flexible materials in contact with the moving belt conveyor.
• Partial enclosures with GI sheets provided for Primary and Secondary Screens. However, large gaps/window opening etc is provided through which dust escapes outside the enclosure. Some smaller units have enclosures made of Gunny Bag Cloths or Plastic Sheet etc.
• G.I. Sheet/Polythene Sheet provided over the belt conveyors in some large stone crushers. Small and medium size SCUs generally do not have such enclosures.
• Hardly any Crushers have enclosures for crusher discharge area, from where substantial dust emission occur.
In the State of Andhra Pradesh, all the products of various sizes are prominently stored in fully enclosed elevated hoppers made of steel and the material is directly loaded from the hoppers into the trucks. This arrangement eliminates secondary dust emissions from open stock piles which generally is quite predominant in most states. However, the dust suppression arrangements for controlling the emissions from the crusher area is generally not satisfactory.

There are three mid-range sizes of AP Impact crushers available for primary, secondary or recycling units.
Factory equipped with four bar rotors, these Impact Crushers can be converted to two bar machines with the addition of a specialized counterweight system. These crushers are medium duty, and are ideally suited for installation on stationary or portable crushing systems.
These impact crusher units are designed for high production primary, secondary, and recycling applications. The standard open rotor design provides sufficient force to handle large feed material. The even heavier SR (solid rotor) units provide all the mass and strength necessary to crush feed material up to 36″.
Whichever unit is ultimately selected, these units are each manufactured with heavy duty, high speed spherical bearings and oversized shafts. Those critical components help to ensure a long lasting operating life for the Impact Crushers.
All machines use greased bearings. They are also all equipped with hydraulically operated hoods, manually adjusted primary curtains, and hydraulically adjusted secondary curtains. Blow bars are available in manganese, and low, medium, and high chrome steels. We also work with foundries to supply the best wear parts for each particular application.
Diamond equipment‘s line of Horizontal Shaft Impact Crushers comprises a versatile selection of Crushers ranging from small secondary units, to large primary units.
With rotor options that include open and solid rotor construction, and 2, 3, and 4 row configurations, the various models can be equipped to satisfy most applications and operator preferences.
The Crushers come complete with hydraulic adjustment mechanisms for primary ans secondary curtains. This provides outstanding operational ease as liners and blow bars wear. Rather than burdensome mechanical adjustments, these machines can be adjusted with a simple to use hydraulic cylinder.
The Impact Crushers are routinely installed in stationary and portable crushing systems. All of the rotors utilize an operator friendly centrifugal wedge system. The rotor is also designed in a manner to minimize the likelihood of catastrophic damage cause by blow bar breakage.

Diamond equipment‘s Log Washers are ideal for scrubbing difficult materials. Tough insoluble clays, conglomerates and soft stone, and certain cemented aggregates are too difficult to clean properly in normal screw machines. The log washer thoroughly scours, breaks down, and cleans the toughest materials.
Trio brand log washers use the same outstanding features found in our fine and coarse washers – features such as heavy duty conveying paddles, a rising column of water, and construction features such as heavy duty tubs, oversize bearings and gears. Heavy duty, replaceable shoes provide a long operating life and protect the shaft and tips from long term wear and tear.
Each cast shoe has a corrugated surface to promote the most severe scrubbing action. Tubular log shafts are also designed to be considerably stronger than competing rectangular shafts used by other vendors. The lower end of the log washer is bolted to a fully machined stub shaft, while the upper end is mounted through a flexible coupling to the output shaft of the heavy duty gearbox. The Trio compound drive divides the operating load over an optimal combination of helical and spur gears, each oversized to ensure maximum operating life.
