Zhejiang Kaishan Compressor's large-scale production leads to cost leadership
Since its establishment, in less than ten years, Kaishan has achieved the largest air compressor scale in the country. In 2010, Zhejiang Kaishan Compressor achieved operating income of 1.625 billion yuan and net profit of 223 million yuan. The market share of screw air compressors was nearly 21%, ranking first in the industry. In addition to independent research and development to achieve import substitution, it is very important that Zhejiang Kaishan compressors have expanded their cost leadership by relying on large-scale production and ultimately achieved overall high-speed growth. Zhejiang Kaishan Compressor R&D team has both academic research and development background and advanced technology research and development background, and has realized the whole process of research and development from concept research and development to laboratory research and development to large-scale industrial production. Thereby, a full-spectrum, large-scale screw mainframe production is realized. With the expansion of market share and the increase in orders, the production capacity of the screw mainframe of Zhejiang Kaishan Compressor has been in a state of saturation. Zhejiang Kaishan Compressor has successively purchased special equipment to increase production lines in order to alleviate the tight production capacity. The advantageous production scale brings significant cost leadership to Kaishan. In recent years, Zhejiang Kaishan Compressor has continuously expanded its product production scale. In 2010, Zhejiang Kaishan Compressor screw air compressor production reached 24,000 units, and the domestic market share was nearly 21%. On the other hand, Zhejiang Kaishan Compressor also greatly reduced the production cost through the screw mainframe: Zhejiang Kaishan Compressor has the self-manufacturing capability of the screw mainframe, and the screw mainframe accounts for 20-30% of the screw air compressor. The self-made screw mainframe can save more than With 17% of production costs, Kaishan has a significant cost advantage compared to companies that do not have the self-manufacturing capabilities of screw mainframes.
A Concrete Plant, also known as a batch plant or batching plant or a Concrete Batching Plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. There are two main types of concrete plants: Dry mix plants and Wet mix plants, and also plants that contain both a transit mix side and a central mix side while utilizing common material storage points. A concrete plant can have a variety of parts and accessories, including: mixers (either tilt drum or horizontal or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.
The heart of the concrete batching plant is the mixer, and there are many types of mixers such as Tilt Drum, Pan, Planetary, Single Shaft and Twin shaft mixer. The twin shaft mixer can ensure an even mixture of concrete through the use of high horsepower motors, while the tilt mixer offers a comparatively large batch of concrete mix. In North America, the predominant central mixer type is a tilt drum style, while in Europe and other parts of the world, a Twin Shaft Mixer is more prevalent. A Pan or Planetary mixer is more common at a precast plant. Aggregate bins have 2 to 6 compartments for storage of various sand and aggregate (rocks, gravel, etc.) sizes, while cement silos are typically one or two compartments, but at times up to 4 compartments in a single silo. Conveyors are typically between 24-48 inches wide and carry aggregate from the ground hopper to the aggregate bin, as well as from the aggregate batcher to the charge chute.
Typical plants are used for ready mix, civil infrastructure, and precast applications.
