The reform of the sand and gravel industry has brought these two types of equipment -- VU sand and gravel aggregate system and mobile crusher
The transformation of the sand and stone industry has brought these two types of equipment -- VU sand and stone aggregate system and mobile crusher. In recent years, domestic's infrastructure construction is at its peak. With the tightening of environmental protection policies and the depletion of natural sand resources, in the face of the annual demand of 20 billion tons of sand and gravel aggregates, the environmental protection mechanism sand equipment and construction waste recycling equipment have become the industry's new favorites, and also become the guarantee for the production and profitability of sand and gravel enterprises.
SMMVIK combines domestic and foreign technologies and research achievements, with rich powder selection technology and sand making technology, and after years of dedicated research and experiments, it has launched the VU series aggregate optimization system. The new dry sand making scheme is used to solve the production problem of high-quality machine-made sand, which also creates new opportunities for the development of the industrial chain of sand, cement, dry mix and commercial mix. This optimization system can greatly improve the grain type, grading and powder content of machine-made sand, so as to reduce the porosity and MB value of machine-made sand, thus significantly improving the workability and strength of concrete and reducing the consumption of cement and additives.
Technical advantages of SMMVIK VU sand aggregate optimization system:
Tower layout. It has tower type highly intensive layout, fully enclosed high environmental protection design, high intelligent automatic control, and the grading of finished products can be adjusted.
Air separation and screening technology. The combination of screening, vibrating distribution, linear screening and negative pressure powder removal are completed in one cavity, and the modulus can be controlled between 2.3 and 3.2.
Environmentally friendly powder collection technology. The production process is fully sealed, and the dust is concentrated in the powder ore bin through negative pressure powder removal, with zero dust discharge.
Flexible regulation. According to different requirements, the fineness modulus can be adjusted from 2.3 to 3.2 and the powder content can be adjusted from 5 to 13% without changing any hardware.
It is comparable to natural sand. The finished sand has excellent gradation, particle type, powder content and other process indicators, and stable performance, which can be comparable to the natural sand with good quality.
At present, the volume of construction waste in domestic is large, but the utilization rate is low. With the shortage of natural sand resources and the rise of sand prices, the resource utilization of construction waste has become a new investment hot spot, and various regions have promoted the recycling of construction waste. In the process of treatment, mobile crusher plays an important role because of its convenience and high efficiency.
The main crushing equipment of SMMVIK mobile crusher is a crusher (jaw crusher, impact crusher, cone crusher and impact crusher can be selected). Materials are uniformly transported to the crusher through the feeder. After being preliminarily crushed by the crusher, a closed system is formed by a circular vibrating screen to achieve the circular crushing of materials. Materials meeting the particle size requirements are output by the conveyor, so as to achieve the production purpose. The mobile crushing station can also remove the round vibrating screen according to the actual production needs, directly crush the materials, and then cooperate with other crushing equipment for specific operation, which is convenient and flexible.
The mobile crusher is flexible in combination. The process of "crushing before screening" can be formed according to different crushing process requirements, and the process of "screening before crushing" can also be formed. The crushing station can be combined into a two-stage crushing and screening system for coarse crushing and fine crushing according to actual needs, or a three-stage crushing and screening system for coarse crushing, medium crushing and fine crushing. It can also operate independently and has great flexibility.
The design philosophy of the mobile crusher is to stand on the customer's position and take the removal of obstacles to crushing operation caused by crushing site, environment, complex basic configuration and complex logistics as the primary solution. Based on the new concept principle of "close handling" of materials. Provide customers with simple and low-cost hardware facilities for project operation.
