Crushed Stone Grade 1-10. Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2
Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes that are suitable for the intended end use.
/ CRUSHING . In order to make use of the rocks or ores obtained through quarrying/explosion in the Mining and Construction sectors, the materials need to be crushed to reduce them to a smaller size. We call this process SIZE REDUCTION or CRUSHING. The goals of the size reduction are as follows: 1.) Obtaining the size or surface area required
A crusher is a machine designed to reduce larg e rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more

11.19.2 Crushed Stone Processing 11.19.2.1 Process Description1-2 Major rock types processed by the rock and crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Minor types include calcareous marl, marble, shell, and slate.
2. The coarsely crushed granite is sent to the second crusher (impact crusher or cone crusher) by belt conveyor for further crushing; 3. The finely crushed granite is sent to the vibrating screen by a belt conveyor for screening. Several granites of different sizes and specifications are screened out. The granite that meets the particle size
The energy in a single ton of granite is equal to 50 tons of coal. The same rock holds immense quantities of valuable metals. Consider this: 100 tons of granite, a chunk somewhat larger than an automobile, contains eight tons of aluminum and five tons of iron. Other ingredients include two tons of magnesium, 180 pounds of manganese, 70 pounds

crushed rock industry is a major contributor to and an indicator of the economic well being of the nation. Forms Of Crushed Rock About three-quarters of the crushed stone production is limestone and dolomite, followed by, in descending order of tonnage: granite, traprock, sandstone and quartzite,
As we already discussed, crushed stone is simply natural rock that is crushed by machinery and then sorted and screened into different groups depending on size and components. This crushing and screening process is typically done at quarries.
1. The jaw rock crusher has simple structure, convenient operation, stable working condition and low operation cost. 2. The quarry crushing machine’s crushing ratio is large and the crushing strength is uniform. 3. The discharge port can be adjusted, so it can meet the needs of different customers. PE1500 1800jaw crusher.
The jaw crusher is used in the first crushing process of the crushing line, which can crush large particles with a compressive strength not exceeding 320MPa to a size of 100mm ~ 300mm. The impact crusher can generally process ore or rock with a compressive strength of up to 350 MPa and less than 500 mm.
1 ½” – This is commonly used as a base for roads, slabs, driveways, walkways, crushed stone patios, interlocking walls and is also used for drainage stone projects, septic systems and dry wells. 2 ½” – This is commonly used for larger construction jobs, such as for road base, tracking pads on job sites, and for use with drainage
In practical applications, granite needs to be crushed into stones of different sizes, so it is necessary to use machines to process and crush them. The selection of the aggregate production line is an important link in the production of modern aggregate mines.

Crushed stone is made from a suitable rock formation during the mining process. A crusher breaks down the rock into various sizes. Crushed stone varies in size. The number “57” is a number that refers to the size sieve that was used to screen and sort the stone.
The sand making machine is the common equipment for making granite sand, and it can process granite into three kinds of aggregate products of 0-5mm, 5-8mm, 8-12mm and 12-15mm. The granite aggregate processed by the sand making machine has a solid shape, strong adhesion and long durability, and is widely used in highways, railways, bridges
The unit can be set up depending availability of raw material and major commercial centre. 5. MANUFACTURING PROCESS The granite stones of various sizes are fed into the jaw crushers for size reduction. Depending on the desired output size of the crushed stone, the raw material may be fed to one or two jaw crushers in a sequence.
The process of rock fragmentation can be divided into three stages in this indentation tests. The failure patterns showed that the granite rock samples all have an obvious crushed rock core and a chiseled pit. The rocks under stress-free conditions can be easily split.
