Ballast Stone Crushing Machine Price in Kenya

Author : Jordan | Last Updated :

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.

This article will start from the analysis of the Kenyan building and construction materials market, the introduction to ballast, ballast production equipment introduction and selection.

Analysis of infrastructure market in Kenya

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.

Kenya's building and construction materials market has a broad prospect, which can be analyzed from the following aspects:

Railway construction in Kenya has gradually stabilized

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.

Road construction in Kenya is growing vigorously

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.

In 2019, Kenyan President Uhuru Kenyatta signed the Kenya Road Commission (Amendment) Bill that is committed to fulfilling the government's commitment to build 10,000 kilometers of roads by 2022.

Large shopping malls and office buildings are sought after by investors

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 — an important source of infrastructure construction materials

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.

Characteristics of ballast stone

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:

Characteristics of ballast stone

Characteristics of ballast stone

  • Weather resistance and high hardness. For example, basalt, quartz stone, diabase and granite.
  • The particle size meets the standard. For example, basalt super ballast shall be no less than 28mm and no more than 58mm; and the standard for first-grade ballast is 25 - 70mm.
  • A sufficiently dense gradation to provide enough force to hold the sleepers in place.
  • Resistance to temperature changes and water erosion.

Uses of ballast stone

Road or railway subgrade

ballast stone use of road or railway subgrade

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.

The function of ballast in road or railway subgrade

  • Increase the stability of the rail and prevent the track from moving. By covering the sleepers with ballast, the movement of the track can be reduced.
  • Disperse the pressure of the sleepers on the roadbed. Ballast can distribute weight more evenly.
  • Reduce the vibration and noise caused by trains to increase passenger comfort. The ballast, which is relatively "soft" (as opposed to rails and sleepers), can absorb the impact of steel wheels running on steel tracks.
  • Enhance drainage capacity. The rain can be quickly drained through the gap between the stones. If the stones are not paved, the soil under the tracks will be soft and the tracks will sink in rainy days.
  • Easy to maintain. The line can be easily corrected by raising or reducing ballast.

Buildings

Another common use of ballast is to mix it with cement and water to make concrete for foundations, structural beams, heavy-duty flagstones, fence posts, curbs, etc.

Advantages of using ballast in buildings

  • The ballast is hard and durable. It has corresponding requirements of its hardness, anti-wear performance, anti-impact properties, crush resistance, atmospheric corrosion resistance, water seepage performance, stability performance, etc.
  • Strengthen the concrete. Filling ballast in concrete can enhance the adhesion of concrete and improve its performance.
  • Cost-effective. Ballast does not need to be replaced or repaired as frequently as other materials, so its maintenance costs are low.

Specifications of ballast stone

The density of the stone is 2g per cubic centimeter. Its specifications are as follows:

Classification and quality of the stone
Category Name Variety name Particle size
specification (mm)
Capacity(kg/m³)
Gravel Extra fine gravel 5--10 About 1400--1500

Note: Gravel is generally crushed with granite, sandstone, quartzite, basalt and so on; Pebble is the collective name for gravel, river light stone and river gravel.Gravel is generally crushed with granite, sandstone, quartzite, basalt and so on; Pebble is the collective name for gravel, river light stone and river gravel.

Analysis of ballast stone price

Generally speaking, the price of building stones in China is $8.5-$11.2 a ton. Due to geographical factors, the price of stone in different regions is different.

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.

Ballast stone production equipment

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.

Jaw crusher

The jaw crusher, widely used in construction materials, railway, water conservancy, chemical industry, etc., is suitable for the crushing of various large materials and ores.

How to select ballast production equipment?

How to choose suitable ballast processing equipment according to your own actual situation? Fote engineers give the following advice:

1 When the output is large and the production site is sufficient, the combination of jaw crusher, impact crusher and vibrating screen can be selected.

When the combination achieves mass production of ballast stone, the grain shape of the finished product is better and the output is larger.

2 When the output is average and the process requirements are simple, you can directly choose the hammer crusher and vibrating screen.

The hammer crusher has unique performance advantages that it has the advantages of beautiful grain shape, strong crushing ability, large crushing ratio and high cost-performance.

3 When the production site is small and the storage place for the ballast stone is relatively dispersed, a mobile crusher can be used to process the ballast.

The mobile crusher can be combined according to the actual situation of the user, with convenient and flexible mobile, advanced technology, and energy-saving and environmentally friendly production process. It is frequently used in many sites that require mobile crushing.
