Summary: Kenya is rich in basalt resources and has unlimited development potential. Basalt crushing machine recommended in Kenya including jaw crusher, cone crusher, impact crusher and sand making machine....
What kind of stone crusher is better for basalt crushing?
Basalt, also called black stone or phonolite, a volcanic rock known for its durability and strength, is primarily found in the Eastern Kenya. The region's abundant basalt reserves have prompted the establishment of basalt crushing production lines, which play a crucial role in various construction projects.
Basalt, as a common non-metallic ore in the sand aggregate industry, has a very high application value in the construction, bridge, road construction and other industries. However, due to the hard nature of basalt, the crushing of basalt needs to go through multiple links such as coarse crushing, fine crushing, and sand making. Different types of equipment have different effects on basalt crushing. So what kind of crushing machine is better for basalt crushing?
Because black stone has a strong hardness and rich silicon content, which leads to serious wear of materials on jaw plate, blow bar, impact plate and other wear-resistant parts during black stone crushing operation, it will greatly increases the crushing cost of basalt. Therefore, according to the material properties of basalt, the crushing equipment with the laminated crushing principle shall be selected as far as possible in the design of the crushing process to reduce wear of wear-resistant parts.
Jaw crusher + cone crusher for basalt crushing
For customers with relatively low requirements on the particle shape of finished basalt aggregates, we recommend adopting jaw and cone crushers to build the production line. This is because the jaw crusher and cone crusher both belong to the crushing equipment using the lamination principle. As mentioned above, the production cost is relatively low because such equipment has less wear on wear-resistant parts.
However, due to the laminated crushing principle, crushed basalt particles produce severe internal cracks, with poor particle shape and a high content of needle‑like and flaky grains. Thus, they cannot deliver the superior mechanical performance of natural polygonal cubic aggregates, limiting their application in construction projects.
jaw crusher + hydraulic cone crusher + impact crusher (vertical shaft impact crusher)
In order to solve this problem, we recommend jaw crusher + hydraulic cone crusher + impact crusher (vertical shaft impact crusher), which can process the basalt with high efficiency and low abrasion of the crushing machine, making up for the shortcomings of jaw crusher + cone crusher crushing process, and get better particle shape of the crushed basalt stones.
Basalt crushing machine recommended in Kenya
1. Coarse crushing: jaw crusher
Jaw crusher is commonly used coarse crushing equipment for basalt processing. The main advantages of jaw crushers are simple structure, high crushing efficiency, wide application range, strong production capacity, and a single-unit output of up to 2000 t/h.
At present, we provide various types of basalt crushing machines in Kenya for customers to choose from, such as PE, PEW and C6X series, which can meet the diverse production needs of Kenyan customers.
2. Medium crushing: cone crusher
The cone crusher is often used for crushing materials with high hardness, mainly to achieve the effect of medium crushing. The materials after jaw crusher processing are subject to medium and fine crushing, which is convenient for the subsequent processing of impact crusher.
The remarkable advantages of cone crushers include excellent wear resistance and fewer wearing parts.
3. Fine crushing: impact crusher
Impact crusher has excellent crushing performance and combines unique characteristics such as unique crushing cavity shape, heavy rotor and excellent wear-resistant materials. Equipped with intelligent control system, fully automatic hydraulic regulator, automatic cover opening, visual touch screen operation interface, real-time display of working status, fault warning, etc., the operation is simple, convenient, efficient and reliable, which can significantly improve the output and quality of products and reduce the cost of maintenance and vulnerable parts.
4. Sand making or shaping: vertical shaft impact crusher
For basalt sand making or shaping, vertical shaft impact crusher is the commonly used crushing machine. It has the following advantages:
a. good quality of finished products
The impact crusher operates on the typical working principle of "rock on rock" and "rock on iron". The operating principle of "rock on iron" can realize rapid impact and crushing of materials and high sand production rate. The working principle of the rock-on-rock crushing mode can reshape basalt particles to make them more rounded and better suited for the sand and aggregate industry.
b. high crushing efficiency
The vertical shaft impact crusher adopts deep cavity impeller design, and the throughput can be increased by more than 30%. The basalt can be fully collided and crushed in the crushing chamber, and the material crushing treatment effect is higher.
c. good wear resistance
The vertical shaft impact crusher is generally made of wear-resistant and impact resistant materials. The specific performance is as follows: the combined hammer head design is adopted, and only the worn parts need to be replaced in daily work, reducing the use cost by more than 30%.
Basalt crushing process design Kenya
Generally, the crushing process of basalt can adopt three-stage crushing process or four-stage crushing process.
Three-stage crushing process:
Basalt is an excellent aggregate of sand and gravel, and three-stage crushing process can reduce production cost.
For small and medium-scaled basalt crushing production line, the crushing process usually adopts the process configuration of two-stage jaw crusher + impact crusher. Two stage jaw crusher can reduce the particle size of basalt to 60mm, and the third stage impact crusher will conduct shaping and crushing, so as to achieve the crushing effect of excellent particle size and low wear cost.
For large-scaled basalt crushing production line, the crushing process can adopt the process configuration of jaw crusher +cone crusher+impact crusher. The cone crusher can control the particle size of basalt to 50mm, and the third level impact crusher can conduct shaping and crushing. The power consumption and wear cost of cone crusher are relatively low, but the investment cost is relatively high
Four-stage crushing process:
- The black stone crushing equipment adopted in the four-stage crushing process includes jaw crushers, cone crushers and vertical shaft impact crushers. The detailed process is as follows:
- (1) Feeding: vibrating feeder.
- (2) Coarse crushing: jaw crusher, feeding particle size is 1500-500mm, crushing to 400-125mm.
- (3) Medium crushing: cone crusher or fine crushing jaw crusher, with feeding particle size of 400-125mm, crushing to 100-50mm.
- (4) Fine crushing: impact crusher (or vertical shaft impact crusher), with feed particle size of 100-50mm, crushing to 32-5mm.
- (5) Screening and dust removal: vibrating screens and dry-type dust collectors
- (6) Shaping: impact crusher or vertical shaft impact crusher (after screening the fine crushed basalt, the qualified basalt particles will be sent to the storage bin through the belt conveyor. If the particle size and shape fail to meet requirements, the returned materials will be sent back to impact crushers or vertical shaft impact crushers via belt conveyors for further crushing and reshaping.).
- (7) Basalt transportation: belt conveyor.
- (8) Control system: in order to reduce dust and soil, the coarse crushed stone is conveyed to the medium crushing cone crusher by the vibrating feeder, and the subsequent conveying between the stones is completed by the belt conveyor.
