Ballast Stone Crushing Machine Price in Kenya

Author : Jordan Last Updated : Sep 24, 2019

Kenya is one of the countries with a good economic base in sub-Saharan Africa, the most developed country in the East African region, and one of the important fulcrums of the “The Belt and Road Initiative” in Africa and one of the first pilot countries for capacity cooperation established by the Chinese government.

Note: “The Belt and Road Initiative” is an acronym for “The Silk Road Economic Belt and the 21st-century Maritime Silk Road”, which is a transnational economic belt initiated by the Government of the People’s Republic of China in 2013.

The main mining products in Kenya are barite, diatomaceous earth, feldspar, gypsum, lime, silicate, fluorite, salt, vermiculite. The building materials produced include cement, coral, granite, limestone, marble, and shale.

Kenya building and construction materials market analysis

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 demand for building materials can be analyzed from the following aspects:

1. Large shopping malls are sought after by investors

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.

2. Office building demand is gradually stabilizing

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.

3. The “The Belt and Road Initiative” brings prosperity to infrastructure materials

The Kenyan construction industry is driven primarily by the two main infrastructure sectors, transportation and construction/housing. 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.

According to Kenya’s “Vision 2030” plan, Kenya will make major improvements to roads, railways, seaports and airport facilities over the next 20 years, and infrastructure development has been established by the “Vision 2030” program as a key growth factor to attract investment and reduce operating costs.

From this point of view, Kenya’s building materials market has broad prospects, and the demand for ballast, sand and gravel aggregates is only increased without decreasing.

Ballast stone - an important source of building materials

Ballast stone is an important source of sand and gravel aggregates which is necessary for urban and rural construction and major infrastructure construction. With the strengthening of ecological environment protection, the supply of natural sand and ballast stone is becoming less and less. At this time, the quarry supplying ballast, sand and gravel has played a pivotal role.

1. Ballast stone specifications

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
Fine gravel 10--20
Middle gravel 20--40
Coarse gravel 40--150
Pebble Extra fine pebble 5--10 About 1600--1800
Fine pebble 10--20
Middle Pebble 20--40
Coarse pebble 40--510
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.

2. Sand specifications

Refer to China’s construction sand standard: sand refers to a particle size of less than 5 mm, or it can be a construction particle processed by stone crushers with a particle size of less than 4.75 mm. The thickness of the sand is divided into 4 levels according to the fineness modulus:

Coarse sand: Fineness modulus is 3.7-3.1, the average particle diameter is 0.5 mm or above;

Medium sand: Fineness modulus is 3.0-2.3, the average particle diameter is 0.5-0.35 mm;

Fine sand: Fineness modulus is 2.2-1.6, the average particle diameter is 0.35-0.25 mm;

Extra fine sand: Fineness modulus is 1.5-0.7, and average particle diameter is 0.25 mm or below.

3. Ballast stone and sand price analysis

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 sand and gravel has been high. These factors indicate that the price of gravel aggregates and even cement continues to rise. Investing in the production of sand and gravel in Kenya is a stable and profitable business.

In addition to Kenya’s strict environmental supervision, it is also affected by the significant reduction in the total amount of natural river sand. The sand price in the new year is still at a higher price.

In some areas of China, the demand for sand and gravel is far greater than supply, and there is a skyrocketing situation. Thus, the prices in these areas are much higher than in other regions. The same situation has also occurred in Kenya, where the demand for ballast, sand and gravel in the country has only increased due to the surge in demand for aggregates.

So what are the equipment for producing sandstone? Next, we will give a detailed introduction.

Ballast, sand and gravel production - stone crushing machine plant

Stone crushing machine plant

Stone crushing machine plant

The stone crushing production line is a combination of special equipment used in the manufacture of sandstone, gravel and other building materials or industrial materials, mainly includes vibrating feeders, jaw crushers, impact crushers, vibrating screens, belt conveyors, concentrated electronic control and other equipment.

The design capacity is generally 50-800T/H. In order to meet the different processing needs of customers, it can be equipped with cone crusher, dust removal equipment. So how should we configure the stone crushing production line?

Common stone crushing machine plant: feeding equipment (vibrating feeder), crushing equipment ( jaw crusher, cone crusher, impact crusher and other main crushing equipment), screening equipment (vibrating screen), etc. Between the conveyors to form a complete stone crushing production line, the following describes the specific equipment for several crushing production lines.

Crushing medium and hard large stone materials

Crushing medium and hard large stone materials

  • 1 Crushing medium and hard large stone materials: Vibrating feeder + jaw crusher + cone crusher or impact crusher + vibrating screen.
  • 2 Crushing soft stone material: In order to save user cost and improve work efficiency, generally, one molding equipment can be used. Vibrating feeder + hammer crusher + vibrating screen.
  • 3 Equipment for environmental protection and control equipment: In order to reduce dust and noise pollution, and improve environmental performance, dust collection, humidification and noise reduction devices are required, and the conveyor belt can also be set in a closed-form.
  • In the crushing stage, the ballast stone can usually be processed to stones below 50 mm.
  • 4 Sand making machine: In addition to the production of various specifications of stones, the customer can also carry out the next step of sand making, directly equipped with a sand making machine behind the crushing equipment, usually processing the material to 0-2 mm, 2 -5 mm, 5-10 mm and other specifications.
