4. Advanced electrical control system makes sure stable operation

Applicable scope

For the hard limestone, granite, basalt, river gravel, slag and other materials over the rule of the aggregate and the operation of artificial sand making for hydroelectric power, building material, highway, city construction industry applications

Principle structure of sand production process
Building stone is even transited to crusher to take coarse crushing by librating feeding machine. The crushed materials are transited into fine crusher for further crushing by rubber belt conveyer. The crushed materials are transited into vibration sieve to separate. After satisfying the requirement of finished product particle size, the materials are transited into sand washer to clean and become finished product by outputting by finished product conveyer belt; the unqualified materials are transited back to vibration sieve for reproduction and form multi-circle in completed circuit. The particle size of finished product can be integrated and leveled based on the requirement from user. If selecting dry production technique, pulverized-coal collector and dust separating equipment should be prepared.

Brief Introduction of Sand Production Line

Large stone is transported to jaw crusher via vibrating feeder for primary crushing. Then crushed material is transported to sand making machine.  Then the stones are screened out into several different types with a vibrating screen. Stone with satisfied size is transported to sand washing machine, then it will be final  product, while overlarge stone is returned back to sand making machine for recrushing. 

Process of Sand Production Line:

The raw material is transferred to jaw crusher for primary crushing by vibrating feeder, then the crushed materials are transferred to sand-making machine through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen. The materials with suitable size will be transferred to sand washing machine, after being washed, then clean final products will be discharged. The others with unsuitable size will be screened from vibrating screen, then will be transferred to the sand-making machine, this forms a closed circuit manifold cycles.
Sizes of final products will be according to our customers' requirements. If it is the dry process, the classifier and deduster will be attached according to you requirement.

Characteristics of Sand production line: 
It is highly automatic. The efficiency is high, operation cost is low, crushing ratio is high, capacity is high, and pollution is very low. Size of final product is even, and with good shape, which complies with requirement for highway. 
In order to minimum occupation area, we try to make full use of space. Advanced electric control system makes the full line very smooth, reliable, and easy to maintenance.

Stone crushing plant, which can also be called rock crushing plant, includes vibrating feeder, jaw crusher, impact crusher or cone crusher, vibrating screen, belt conveyor and centrally electric controlling system, etc. The designed capacity is from 40t/h to 600t/h. To meet customer’s specific requirement for stone crushing, we can also add other equipment such as cone crusher, dust catcher in the crushing plant.

Production Process of Stone Crushing Plant

The big stones in the stone production line are coarsely crushed in the jaw crusher sent by the vibrating feeders through the bunker evenly. The coarsely crushed stones are sent to the impact crusher by the belt conveyor for further crushing. After tertiary crushing, the materials are screened in the vibrating screen through the belt conveyor to classify several sizes of stones.The stones which can meet the requirements will be sent to the finished product material piles by the belt conveyor, while the left stones will be sent to the impact crusher for another further crushing to form a closed circuit cycle. The finished product can be classified and combined according to the customers' needs. The dust removal equipment can be added in order to protect the environment.

Advantages of Rock Crushing Plant

It is widely used in mine, metallurgy, building material, highway, railway, water irrigation and chemical industry. It has many features such as big crushing ratio, even granularity, simple structure, reliable working condition, convenient repair and economical operation..

    1  this line is widely used in the world  nowadays and  has the features of high reduction ratio,uniform granularities,simple structure and easy maintenance.   It has two types: primary Jaw Crusher and secondary  jaw Crusher.  The compressive strength of the final products is up to  320MPa.The Jaw crusher of Iarge and medium-size are the key products of our company. And our company takes the leading place in designing and producing large Jaw Crushers in China.

   2   Impact crusher can deaI with any large,middle ,and small materials(granite,Iimestone,concrete,etc.) With length no longer  than 500mm,and compressive strength less than 350Mpa.It is widely used in mining,highway, uailway, and construction industries to produce artificial sandstone materials.At present,the comprehensive capacity of lmpact crusher is prior to Cone Crusher and Hammer Crusher. 

    3   The Circular Vibrating Screen has the advantages of even and reilation operation, low energy consumption ,low noise,long life,even vibration and high efficiency of sieving. Being high efficient sieving equipment,it is wildly used in mining,coal,metallurgy,building materials,refractory materials,light industry and chemisry industries.

     4 Workina Principle.

 The vibrating exciter is installed in the side plate of sieving box. Together with motor,the exciter rotates through coupling or belt,which produces centrifugal inertia  force.The sieving screen is the main easy-wear part.The perforated sieving plate and rubber sieving plate can be knitted by austenitic manganese steel,according to different raw materials and customers requirements.The sieving plate has the types of single layer and double-layers.The sieve obliquity can be adjusted by the height of the supporting seat of spring.
