Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

Answer: Jaw crusher is mainly used for primary stage crushing. Cone crusher is installed at secondary stage. It gives more or less uniform size aggregate. However, for aggregate with rounded edges (better for load bearing), Horizontal Shaft Impactor or Vertical Shaft Impactor.

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

First of all, break the big stone boulders to smaller size manually. Then it is fed to the stone crusher. The crusher can accept the stone size of 175mm. Stone crushing is the two-stage process. In the first. stage, crush the 175mm stone to about 50mm. Thereafter, fit the crusher with a conversion kit to enable granulation of 5 to 20mm.

The procedure of crushing the stone has three stages. The first stage is breaking down the stone to small sizes. The second stage is crushing down the sizable stones to suit a specific purpose. On the third stage, the stones are screened for finished products. Sand and gravel are the most common minerals used in creating concrete.

Cost and Availability of Different Stone In considering the cost of crusher run vs. washed stone, realize that 25% to 45% of the weight of crusher run gravel is composed of particles smaller than 2 mm. Although quarries price gravel on a per-ton basis, its simpler to calculate gravel needs and compare costs based on cubic yards.

So, one of the first projects for the R1100D impact crusher was to process 10,000 m³ of gravel that comes from a pit under a water storage reservoir in Mohammedia near Casablanca. Gravel is a rather abrasive stone that includes pure iron ore with a high specific gravity weighing up to 2.8kg/m³. The size of the loaded material was up to 1000

Crushed gravel is an aggregate frequently used in construction. The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry and then transported to the rock crusher, which begins the process of crushing the larger stones into more manageable pieces.

After initial crushing and screening, industrial sand and gravel are washed to remove unwanted dust and debris and are then screened and classified again. The sand (now containing 25 to 30 percent moisture) or gravel then goes to an attrition scrubbing system that removes surface stains from the material by rubbing in an agitated, high-density

School children work only at weekends or after class, crushing stones into gravel that is then used to construct roads and buildings. But those children not enrolled in school can work more than eight hours a day, six or even seven days a week. Between 150 and 200 children labour at the quarry, Otchoun said.

Aggregate is typically divided into two components:! Fine aggregate including sand – material passing a 3/8-inch screen sieve, essentially all passing a # 4 sieve (i.e., a 0.187-inch square opening). ! Coarse aggregate including gravel – generally considered being crushed stone or gravel, almost all of which is retained on a No. 4 sieve.

Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water.
