Good quality ballast are clean and graded crushed stone aggregates with hard, dense, angular particle structure providing sharp corners and cubical fragments with a minimum of flat and elongated pieces . The sleepers lie on top of the ballast, most commonly used type of sleepers is reinforced concrete and is not structurally connected to the ballast, are smooth at the top, but have a very rough surface at the bottom where they come in contact with the ballast . The rough surface makes it possible for the ballast . interact together in restraining the external forces. Ballasts are broken pieces of hard rock having a range of 25mm - 60mm size, over which the railway tracks are laid.
Stone quarry use ballast crusher and ballast crushing plant to get ballast. Different type of crusher has different application. Ballast crushing and screening plant consists of jaw crusher, standard cone crusher, short head cone crusher, impact crusher, VSI crusher, mobile jaw crusher, portable cone crusher and mobile impact crusher.

The ballast that are unqualified returns to the crushing plant for crushing again.
Kenya is one of the countries with a sound economic foundation in sub-Saharan Africa and the most developed country in East Africa. In recent years, Kenya's infrastructure construction has developed rapidly. Ballast stone is an important raw material for road and railway construction as well as concrete, so many customers are investing in ballast production line equipment.
The Global Infrastructure Outlook Report released by the G20 in July 2017 stated that in order to achieve the UN Sustainable Development Goals (SDGs), Kenya would need $206 billion for infrastructure construction by 2040, which is 41% higher than current investment levels. Kenya's construction industry is driven by two main infrastructure sectors, transport and construction.
The Kenya railway upgrade plan has been launched as part of the Belt and Road initiative. The first phase of the project, Mombasa connecting to Nairobi, has been started in 2017; the second phase of the project, the railway connecting Nairobi and Naivasha, has been completed in 2019.
But the program is not over. Over the next few years, the railway project will connect six other East African countries. President Uhuru Kenyatta believes it is critical to the "Vision 2030" to transform Kenya into a middle-income country.
In the past decade, the Kenyan Government has spent 1 trillion shillings modernizing and building road networks in cities such as Nairobi, Mombasa, Eldoret and Kisumu. This has increased the country's road network from less than 60,000 kilometers a decade ago to more than 160,000 kilometers nowadays.
According to Kenya's 2016 economic report, the Kenyan construction industry is expected to grow at an average annual rate of 7.3% during 2015-2025, which sets a positive tone for Kenya's building materials boom.
The development of urbanization and the continuous expansion of the middle class have increased consumer demand in Kenya. The Kenyan people are also increasingly favoring shopping malls and other consumer places. The high demand has prompted Kenyan domestic and foreign investors to focus on the construction of large shopping malls.
Since 2012, Kenya Airways has opened several new routes to Central Africa and West Africa. With the help of transportation hubs, Kenya has attracted a large number of multinational companies including General Electric, Google, IBM and Nestle to settle in Nairobi. The office building project has gradually reached supply and demand balance from oversupply.
Ballast stone is a building material necessary for urban and rural construction as well as major infrastructure construction, and it is also an important source of concrete and gravel aggregates. Quarries supplying ballast and gravel play a decisive role.
Ballast refers to coarse gravels used to lay road or railway subgrade. The most widely used ballast is broken rocks, preferably igneous rocks and hard limestones. Ballast has the following characteristics:
Ballast can be used to build sidewalks and railway track beds, mainly for railway foundation beds. Its structure is to connect two steel rails with fasteners and fix them to sleepers through the rubber insulation pad, and ballast are placed under the sleepers.
In recent years, Kenya's infrastructure and personal repairs have been in full swing, and the demand for gravel has been high. These factors indicate that the price of gravel aggregates and even that of cement will continue to rise. Investing in the production of ballast stone in Kenya is a stable and profitable business.
In some areas of China, the demand for ballast stone is far greater than supply, and there is a skyrocketing situation. Thus, its price in these areas is much higher than that of other regions. The same situation has also occurred in Kenya, where the demand for ballast in the country has increased due to the surge in demand for aggregates.
The quality requirements of ballast stone are very strict, so you need to be very careful in the selection of ballast processing equipment. What is the equipment for producing ballast? Next, we will introduce in detail.
