so you'll have 380 tons or so of rebar to sell for scrap.

Goto Chunlei to know more.

380 tons @ $190 per ton = $74,100, so what your saying is I can make a profit

OK, I'll be honest with you guys, at this point I'm so screwed its not funny. I've been advertising on Craigslist for clean fill, and up till Monday its been good usable material that I've been using to level areas of the property. So I got a call Friday, 18 truckloads of broken concrete, nothing bigger than a basketball, just what I needed to fill in the front parking area and bring one end up 3 feet. I was expecting 12 yard dumptrucks, so I was a little surprised Monday morning when an 18 wheeler end dump arrived. The first 6 loads were well broken concrete, the next 4 loads had a few big boulders, the next 2 loads were nothing but massive boulders of concrete, so I said stop, driver said it was the last load, so I figured I could deal with it. Tuesday morning I was leaving and realized more big boulders had been dumped, at least 3 loads worth. Ran back to the house to get the and as I step out of the house another truck is pulling in the driveway *#@^!, by the time I got up there he was dumping. After that truck pulled out I jumped on the loader and scooped up a bunch of big boulders and blocked the driveway

I've decided to use the boulder sized stuff to build a retaining wall, this will let me fill in an unused area and get it ready to be covered in road base, gravel, crushed concrete something. Spent about 3 hours this evening moving boulders, got at least 300 feet of boulders lined up, I'll be at it all weekend, but there is still too much in the front parking area, almost too much to work in:shrug:

There are several different rock crusher options, and each is used for slightly different purposes. When choosing a rock crusher for your operations, it's important to first identify the stage of crushing you're using the machine for. This will determine the appropriate solution for your needs.

Rock Crushing Stages

There are three different stages of concrete crushing:

• Primary ' This stage involves crushing coarse materials in order to allow them to be transported on a conveyer belt. These machines need to be able to handle a large capacity and accept the raw materials without suffering a blockage.
• Secondary ' In this stage, the coarse materials produced during primary crushing are broken down even more in preparation for final crushing. The purpose of secondary crushing is to achieve the greatest possible reduction in particle size for the lowest possible cost.
• Tertiary ' This stage further refines particles to make them as fine as possible. The quality and quantity of fine products must be considered when determining the right concrete crusher for this phase of the process.

Additional Criteria for Choosing a Rock Crusher

In addition to identifying the proper stage being used with your rock crusher, you should consider the following criteria:

• Abrasiveness and hardness ' What type of material are you trying to crush? You must know the abrasiveness and hardness of the material in order to determine the maximum force or compressive strength the material can withstand before it breaks.
• Dimensions ' You need to identify the maximum length, width and thickness of the materials entering your rock crusher.
• Granulometric requirement ' What grain size are you trying to achieve after crushing is complete?
• Capacity ' You'll need to determine the processing capacity required for your needs.

 

Rock Crusher Options

Once you've evaluated the criteria discussed above, it's time to choose a rock crusher that will effectively address your specific applications. Each of the following options will deliver different results and are ideally suited to different stages of the process.

 

Jaw Crusher

A jaw crusher is a type of compression crusher that is most commonly used for primary crushing. The material being crushed is squeezed between a stationary piece of steel and a moving piece of steel. This produces the coarsest material since the rock is being crushed along its natural lines of weakness. Jaw crushers are effective the hard and abrasive materials such as granite, ores and recycled concrete.

Advantages of jaw crushers include:

• Reduces raw materials to a size of 150 mm
• Maintenance and operating costs are relatively low

Drawbacks to this option include:

• • Not able to produce grain sizes smaller than 150 mm
  • Cannot handle materials that have clay or metal mixed with rock

 

Cone Crushers

As with jaw crushers, these machines are compression crushers that use a stationary and moving piece of steel to break up the material. Cone crushers use a rotating head to crush the rock within a steel bowl. After initially being broken down in this manner, the material will travel through a narrow opening at the bottom of the bowl to achieve a finer grain size.

Cone crushers can be used with a variety of materials, ranging from medium to hard. They are typically used with secondary crushing, especially when the final shape of the crushed material is important.

Advantages of cone crushers include:

• Easy to adjust
• High productivity output
• Sturdy construction
• Affordable
• Low operating costs

Drawbacks to this option include:

• Inability to accommodate materials of all sizes (materials must be 200 mm or smaller before entering the concrete crusher)
• Inability to produce a homogeneous finished product
• Cannot handle clay or metal mixed with rock

 

Impact Crushers

Impact crushers break down material by leveraging mass and velocity. The material being crushed is hit by hammers. This material then travels towards a metal plate, where the rock breaks apart and bounces back up to be hit by the hammers again. This process continues until you've achieved your desired final size.

Impact crushers can be used with all three stages of crushing. While they can handle materials of all hardness, they are ideally suited for soft to medium rocks.

Advantages of impact crushers include:

• Greater ability to control the final size of the crushed materials
• Can accommodate clay, dirt or metal mixed with the rock
• Produce a more uniform grain size
• High production capacity

Drawbacks to this option include:

• Higher operating costs

 

Stationary vs Mobile Jaw Crushers

When purchasing a jaw crusher, you can choose between a stationary option and a portable jaw crusher. Stationary crushers are typically sturdier. However, you're limited by the fact that it must reside in one place all the time. Mobile jaw crushers, on the other hand, give you the ability to move the machine to the precise location where you need it at all times. For this reason, they often provide a more versatile solution.
