Jaws and Primary Gyratory Crushers:
The primary crusher's purpose is to reduce the stone to a manageable size. Jaw and primary gyratory crushers achieve this. For a big feed volume, primary gyratory crushers have an immense size and radial bearing system. Stone gyratory crushers crush and mix up the materials to achieve a 1st completion goal. Jaw crushers have moving jaws and fixed jaws that crush the stone and decrease its size.
Impactors and Secondary Cone Crushers:
The impactor's job is to further reduce the stone's size. Impactors have an open design that allows for the easy and quick exchange of wear components. The impaction of the growing stone through horizontal shafts is its unique way of crushing. Secondary cone crushers also reduce the size of the stone. They have features like a high stroke, a larger head diameter, a constant performance, and the ability to use inter-parts. Impactors and secondary cone crushers help to further achieve the end goal.
Sand Makers:
Sand makers' job is to produce sand. Sand makers have a wet system that allows water to be added to the dry process and a protection system for the motor. The vertical shaft and the striking force of the anvil are two techniques they use to create sand and improve the stone's shape.
Screens and Dewatering Units:
Screens separate the different grades of crushed stone, while dewatering units drain the excess water from the sand to allow it to dry and become ready for sale. Screens have several decks to separate more stone with greater efficiency. Screens are either circular or linear. Circular screens give a circular motion, while linear ones move in a straight line. The secondary crusher's output is now screened to grade. The sand with water is put through a dewatering unit. The sand then goes into a washing plant.
Washing Plant:
Washing plants clean the stone. In the case of sand, impurities are removed to achieve the required standards and qualities. A washing plant's features are an eco-friendly design, a high dirt-removal rate, a user-amenable feature, and multi-grade products. In the end, there will be crushed stone of several sizes and grades and sand.
Details regarding each component and their capacity are as follows:
Crushers
A large diversity of stone crushers are used in the stone crusher plant.
Each jaw stone crushes different kinds of stones. Usually, its size makes massive and rough materials squeeze and break smaller. Other types, known as impact crushers use a rotating rotor that carries hammers and bars to smash the stones that collide with the device or among themselves, to crush them.
Conveyors
The raw material is launched into the jaw crusher by a feeder or a conveyor belt. The jaw crusher inverts and breaks the larger stone fragments, which are further moved through another conveyor belt to an impact or secondary crusher, where the remaining pieces are further crushed.
Finally, the processed material is placed over a stockpile or loaded into a truck, railcar, or ship by another conveyor belt.
Vibrating screens
The particles are screened according to their size, which will determine where they are usually stopped and how they will be used. In this way, the vibrating screens will separate the small processed material from the larger ones to be sent back to the crushers.
Other components that may appear in a stone crusher plant are:
Washings
Usually a double decks screen where smaller materials go to the stockpile and the larger ones are usually treated by a sand recovery unit, which consists of a screw that separates the water from the sand.
Mills
Usually impact and/or disintegrators that break and crush the material to produce sand. The disintegrators use a rotating drum that has hammers attached to it.
Dust control
Usually water is sprayed on the processing area by a sprinkler system. Other methods are extraction by a vacuum system or disposal by a simultaneous segregation method.
Maintenance
Some pointers for optimal crushers' maintenance tips:
Stone crushing plants are essential equipment for various industries that require crushed stones and aggregates. The following are the typical usage scenarios for stone crushing plants:
When looking for stone crushing prices, it is also very important to focus on what each price represents. This means studying the type of stone crusher that is being offered at a particular price.
Q1: What are the factors that make the price of a stone crusher plant to fluctuate?
A1: The prices of stone crusher plants are very dynamic. It has been noted that local factors such as demand and supply economics play a big role in the pricing of these plants. The legal and regulatory factors and tax policies of a country also affect the pricing of stone crusher plants. Facilities such as infrastructure and connectivity of the locality where the machinery will be installed can impact the transportation costs, thereby influencing the final price of the plant. Exchange rates will also impact the import prices of the stone crusher plant, which will eventually affect the local retail price.
Q2: Is there a reason to worry about the stone crusher plant's pricing if one is investing in the industry?
A2: The stone crushing industry is very lucrative and directly impacts the construction business. Therefore, even a fluctuation in the price of the stone crusher plant should not hinder investment in the industry.
Q3: What type of stone crusher plant should one invest in based on its pricing?
A3: If the intention of investing in the stone crusher plant is to cater only to local demands, then a medium-sized plant should be ideal. However, if a large-scale stone crusher plant is to be set up to meet high-demand requirements that reach beyond national borders, then it would be prudent to invest in large-scale plants even though the price may be steep.
Q4: Are stone crusher plant prices the same worldwide?
A4: Prices are not the same worldwide because they depend on several factors, including demand and supply, regulatory policies, transportation costs, taxation, and exchange rates. However, upon doing a market survey, one can find out the prices of different stone crusher plants worldwide and the reasons for the differences.
