Stone Crushing and Stone Shaping Machine

Stone Crushing and Shaping Machine can be widely used in highway, railway, hydropower station, bridges, tunnels, concrete mixing plant, construction and other industries that related to the gravel shaping and gravel processing field. Especially for concrete whose strength grade is greater than C60, and for anti-freezing, impermeable or concrete aggregates with other requirements, as well as shaping for gravel with continuous size fraction used in highway road.

Stone Shaping Machine

Stone Crushing and Shaping Machine

It can be directly used as secondary crusher for jaw crusher and cone crusher, also can be used independently for shaping purpose. It is the substitution of impact crusher among fine crushing equipments. Its main performance indexes are much better than impact crusher.

Special Technology:

Integrated with crushing and shaping function or single shaping function. According to different stones, different purposes, changing the crushing cavity feeding method and the ore structure can both ensure the gravel shape to meet the standard, and can greatly improve production, reduce operating costs. It enables one machine two uses at any time as per different applications without expanding investment.

Superior performance and long service life.

1. Special lubrication circulation system ensures the temperature rise at 25℃ or less;
2. Brand new automatic protection device provides vibration, oil filter, and alarm warning system, eliminating hidden troubles in advance;
3. New oil filter system ensures bearings and other transmission devices free from accidental abrasion, increases service life;
4. Optimized arrangement design of wear resistant materials improve service life by more than 40%, therefore reduce cost by more than 40%.
5. Main materials have adopted configuration from international famous factories, when producing normal materials, the machine can run continuously for over 1 month without shutdown.

Upgraded quality and high crushing efficiency

1. Excellent impeller design greatly reduces the resistance of passing material, improves material throughput and crushing ratio, its efficiency is higher than traditional impact crusher by over 30% ~ 60%;
2. Hydraulic device, automatic lift cap, reduces manual labor intensity, maintenance is extremely convenient, and fundamentally improves the efficiency;
3. New technique of hot riveting is adopted to frame, which enhances equipment structural strength and toughness, ensures operation stability, upgrades the quality to a new level;
4. Adopted world advanced light oil anti-leakage device, removed the trouble to replace the oil seal;
5. Increases feed size, maximum feed size can be 80mm(traditional equipment can only takes maximum feed size 50mm).

Stone shaping line

Stone shaping machine is used after the final crushing process In the complete stone crushing plant, so the crushed stones can be done reshape to meet high demand on shape of highway and railway track ballast.

General, we add a vsi crusher, it unite crushing and shaping function. After that, the shaped stone materials go through screening process for eligible building materials.

VSI series crusher is the new generation stone shaping equipment designed by our companys technicians adopting Bamako theory. It dramatically decreases the use cost of the wearing parts. This equipment has the feature of low operation cost, easy maintenance, and low noise.

With the cover opening installation of hydraulic pressure, VSI series stone shaping Machine is very convenient to change the wearing parts and decreases the machine halt time. The light oil lubrication system extremely enlarges the life of the bearing and reduces the consumption of the power.

Features of stone shaping machine

1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity.
3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
4. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.
6. Special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. In addition, this equipment can not only crush stone, but also iron.
7. Shape of material-through device is better designed, which improve the utilization ratio.

Working Principle of Stone Shaping Machine

Feed at center: After materials are fed into the hopper, they enter through central feeding hole to the impellers, which are rotating at a high speed. Then, the materials are accelerated and thrown out of impellers to firstly hit with part of materials rebounded from crushing cavity. And then, they impact onto swirl material liner of swirl cavity together (stone by stone), firstly be rebounded to the top of crushing cavity, change direction and fall down, hit with the materials shot from impellers again, forming a continous material layer, finally the materials are discharged from the discharge opening at the bottom.

Feed both at center and at sides: After materials are fed into hopper, they fall down through circular hole and are divided into two parts by the distributing mantle. One part enters the impellers, which are rotating at high speed; the other part fall down along the mantle. The first part is accelerated at the impeller area and are thrown out and to strike on the falling materials at sides. Then, they together strike on the material layers in whirlpool cavity and again be shot back to strike on another part of materials which are shot from the impeller flow and form a continuous material curtain. The final products will be discharged from the discharge open at the bottom.
