VERTICAL SHAFT IMPACT CRUSHER IN THE MIDDLE OF THE WORLD

Rock on Rock Vertical Shaft Impact Crusher MVI 90 started operation in the middle of the World for limestone crushing plant.

Meka MVI90 crusher has a tested and proven rotor that functions like a high-speed dry stone pump that launches rocks at a continuous pace.

The material fed into the machine accelerates in the rotor, and is continuously launched inside the crushing chamber at speeds of 50–75 m/sec. . This process forms a stone lining and causes the MVI90 to instigate a crushing and grinding chain reaction.

This, along with other variables, including rotor diameter, rotor speed and crushing chamber profile, can increase power efficiency, reduce abrasion, provide efficient control of the grinding and crushing process, and adjust the fineness of the produced material from minimum to maximum.

Vertical Shaft Impact (VSI) crushers are designed to be used in secondary, tertiary or quaternary stage crushing. The crushers are suitable for a wide range of applications including the production of high quality manufactured sand, well formed aggregates and industrial minerals. Crushers can also be used for shaping or removal of soft stone from aggregate. Advanced alternatives with open table designs, multi-port rotor and larger bearings than many other VSI crushers are the main reasons for our crushers to provide high value solutions and deliver high performance. We provide static, wheel mounted VSI plants and components. VSI Impact Crushers are suitable for manufactured sand, re-crush of slow selling stocks, cubical products fractured gravel, material beneficiation, crushing of cement clinker before mills and glass recycling applications.

Safety features includes; open lid safety lock, low oil flow rate and high oil temperature shut off switches.

Excessive vibration alarm system that includes a maintenance alarm to alert you to potential problems. If excess vibration occurs, the vibration switch will shut down the crusher to protect it from possible damage.

Dual drive design reduces the radial and thrust loading on the electric motors, resulting in an extra-long service life for the motors

ROR configurations are recommended when crushing the most abrasive materials, in tertiary and quaternary applications where additional fines production is desired.

Autogenous crushing occurs inside crusher chamber between material thrown from rotor and material resting on rock shelf or material springing back from rock shelf.

Production of cubical high quality aggregates and sand from highly abrasive input materials, such as gravel, granite, quartzite etc

Crushing of highly abrasives materials, such as aluminum oxide, ferrosilicon, abrasives, glass etc

Selective crushing of slags from steel mills, waste incineration plants etc.

Concrete Batching Plants

Concrete Batching Plants are used for manufacturing of high-quality concrete in a variety of construction applications, like buildings, roads, bridges, airports and many others. Wide range of Ready Mix Concrete Batching Plants along with Concrete Mixers. Mobile, Compact and Stationary rmc plants can be configured as special solutions for different kinds of concrete types, like Roller Compacted Concrete, Road Concrete, Extra Heavy Concrete, Fiber Reinforced Concrete and others, according to the customers’ specific requests. Single Shaft, Twin Shaft and Planetary Concrete Mixers will cover a wide range of needs and add flexibility to manufacturing process. also offers different components and options for concrete industry that increase performance, add flexibility, improve accountability and operational characteristics.

When draining aggregates at the batch plant site, provide provisions for disposal of drainage water and for clear-cut separation of drained from undrained materials. Keep materials of different sources/classes or gradations separated. Sometimes, timber bulkheads are erected to save space in the Producer’s storage yard. These are satisfactory if built properly.

Erect the weighing bins and hoppers on firm foundations to avoid settlement, which might affect the accuracy of the equipment.

Check the general layout of the plant before the equipment is erected to ensure efficient operation and adequate space for stockpiling and handling materials in compliance with specification requirements. Whenever possible, avoid the arrangement and erection of batching plants in congested locations which are not conducive to proper handling of materials. Small stockpiles result in segregation and non-uniformity of materials and very poor control of the concrete. Concrete Batching Plants Once a batching plant is erected in such a location, it is difficult to improve conditions. Experience has demonstrated that the most uniform concrete is produced when the batching plant is favored by adequate space for the maintenance of large stockpiles of materials.

Ready Mix Concrete Plants

Ready Mix Concrete Batching Plants are used for mass production of high-quality concrete for all construction purposes. Mobile, Compact and Stationary models are available and can be chosen according to the application, project, site condition and customer preferences. Complex solutions can be designed upon request.

Few things are more aggravating to produce on a worksite thanconcrete. Bags of cement, sand, aggregate (gravel) and possibly otheradditives must be delivered to the construction area. A supply of clean wateris also necessary, along with a rented concrete mixing hopper. Even after allthe dusty and heavy ingredients have been loaded into the hopper, one smallerror in the wet/dry ratio can render an entire batch of concrete unusable.One common solution to this messy and time-consuming problem is ready mixconcrete

Concrete Plants

Do you have a design in mind for your blog? Whether you prefer a trendy postcard look or you’re going for a more editorial style blog - there’s a stunning layout for everyone.

Today, Ready mix concrete comprises a mix of aggregates, cement, waterand a variety of admixtures. Understanding these individual ingredients in alittle more detail provides an insight into ways of obtaining the best results fordifferent types of project

The main difference between the concrete found in these classicalcivilizations and modern ready mixed concrete is the binding agent. TheEgyptians used crushed gypsum, the Romans knew how to make lime byburning crushed limestone and they even discovered that adding volcanic ashor old bricks and tiles improved the setting characteristics of their cement.

Rmc is a specialized material in which the cement aggregates and otheringredients are weigh-batched at a plant in a central mixer or truck mixer,before delivery to the construction site in a condition ready for placing by thebuilder.

Ready mix concrete manufacturers use the same cement, aggregate,additives and water, but the product is created off-site and usually deliveredin bulk to the construction zone. Large trucks with revolving hoppers replacethe smaller rented versions used directly on the site. Ready mix concrete is

ordered directly from a local supplier who can create custom blends or bulkorders. Some contractors may need more aggregate in their concrete, forexample, or special curatives added for faster drying times.

Ready Mix Concrete Plants

It is not unusual to find ready mix concrete companies in the industrialsections of cities or in rural areas. Massive piles of sand, gravel and otheraggregates are usually stockpiled on the grounds, along with earthmovingequipment and delivery trucks. Companies which specialize in ready mixconcrete may also provide gravel for roadway construction and cement forother construction projects.

Ready mix concrete companies often belong to professionalorganizations which oversee all of their members. Any innovation in the readymix concrete industry can be quickly implemented or discussed duringregular meetings. Other issues which can affect the ready mix concrete industry are maintaining professional standards, environmental concerns andlocal laws concerning heavy transportation.
