Main types of stone crusher

  • 1. Jaw Crusher
  • The jaw crusher is an early crushing device. Because of its simple structure, firmness, reliable work, easy maintenance and overhaul, and relatively low production and construction costs, it is still widely used in metallurgy, chemical industry, building materials, electricity, Industrial sectors such as transportation are used to crush coarse, medium and fine crushed various ores and rocks with compressive strengths ranging from 147 to 245 MPa. In recent years, our factory has specially developed a powerful jaw crusher to meet the needs of crushing high-strength and high-hardness micro-carbon ferrochrome in metallurgy, mining, construction and other industrial sectors. The jaw crusher is mainly used for medium-size crushing of various ores and bulk materials, and is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The higher compressive strength of the crushed material is 320 MPa.

  • 2, impact crusher
  • The impact crusher (reverse blow) is a new generation of impact crusher developed by our company based on the absorption of advanced technology at home and abroad, combined with the specific industrial and mining conditions of the domestic sand and gravel industry. It adopts newer manufacturing technology and unique structural design. The finished product is cubic, no tension and crack, and the granular shape is quite good. It can crush all kinds of coarse, medium and small, and the compressive strength does not exceed 350MPa. Fine materials (granite, limestone, concrete, etc.) are widely used in various ore crushing, railway, highway, energy, cement, chemical, construction and other industries. The size of the discharge material can be adjusted, and the crushing specifications are diversified. The impact crusher can process materials with a side length of 100-500 mm, and its compressive strength is up to 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. It is suitable for crushing medium and hard materials, such as cement plants. The limestone is broken, which has the advantages of large production capacity and small discharge particle size.

  • 3, cone crusher
  • Cone crusher is widely used in mines, cement plants and sand and gravel industries. It is used for various mine rocks with medium and fine crushing pressure below 350 MPa, such as iron ore, non-ferrous metal ore, basalt, granite, limestone. , sandstone, pebbles, etc. The combination of high-performance crushing chamber type and high crushing frequency makes HPC high-efficiency hydraulic cone breaking (HPC high-efficiency hydraulic cone crusher) greatly improved in processing capacity, and because of the principle of laminating crushing, the broken products are mostly cubic structures. The needle-like material is greatly reduced. HPC high-efficiency hydraulic cone crusher (HPC high-efficiency hydraulic cone crusher) is simple in structure, easy to operate and maintain, and the discharge port is easy and quick to adjust. It saves time and labor during maintenance, especially the lining plate is easy to replace quickly, reducing downtime.

  • 4, hammer crusher
  • Hammer crusher is one of the main equipments for crushing limestone, coal or other brittle materials with medium hardness below the metallurgical, building materials, chemical and hydropower industries. It has special characteristics such as large crushing ratio, high production capacity and uniform product size. Our company has more than 30 years of history in designing and manufacturing hammer crushers with advanced product structure, reliable performance, stable operation and low energy consumption. The hammer crusher produced by our company is reasonable in price and has formed a series, which is very popular among users at home and abroad.

  • 5, impact crusher
  • The impact crusher is widely used in various kinds of hard and brittle materials such as rock, abrasive, refractory, cement clinker, quartz stone, iron ore, concrete aggregate, etc. It is suitable for sand for construction and gravel for road construction. The impact crusher has simple structure, low price, stable operation, high efficiency and energy saving. The material self-lining in the impeller and vortex crushing chamber greatly reduces the wear parts cost and maintenance workload. The impact crusher effectively solves the raw materials such as glass. The problem of “iron pollution” in the crushing process and the “calendar steel” problem in the process of steel slag crushing, the ingenious internal airflow self-circulation eliminates the dust dispersion.

  • 6, mobile crusher
  • The introduction of the mobile crusher eliminates the cumbersome steel frame structure and the construction of the foundation, which saves a lot of time. The mobile crushing station can directly select the site and directly drive to the site without direct transportation to directly reach the finished product granularity. It is especially suitable for small crushing sites, suitable for construction waste disposal and construction waste. The mobile crushing station also greatly reduced the investment cost, but increased the investment income.

Use of stone crusher

  • 1. Preparation of industrial gravel
  • After crushing and sifting large pieces of stone, various crushed stones of different required sizes can be obtained. These gravel can be prepared into concrete. They are widely used in construction, hydropower and other industries. A large amount of gravel is also required in the construction of railway subgrades.

  • 2. Separating useful minerals from ore
  • The ore is monometallic and polymetallic, and the ore is mostly a lower grade ore. After the ore is crushed, the useful metal can be separated from the gangue and harmful impurities in the ore, and as a raw material for beneficiation, impurities are removed to obtain a high-grade concentrate.

  • 3, grinding to provide raw materials
  • The raw materials required for the grinding process to have a certain particle size are provided by the crushed product. For example, in coking plants, sintering plants, pellet plants, powder metallurgy, cement and other departments, the raw materials are supplied by the crushing process, and then the products are brought to the required particle size and powder state by grinding.

Factors affecting the production capacity of stone crushers

  • 1. The wear resistance of the crushing parts of the crushing equipment is better. The crushing ability is larger. If it is not wear-resistant, it will affect the crushing capacity. Therefore, the main factor affecting the crusher's production capacity is whether the crusher hammer is wear-resistant.
  • 2. The hardness of the material. The harder the material is, the more difficult it is to break, and the more severe the wear on the equipment. The speed of breaking is slow, of course, the crushing ability is small.
  • 3. The humidity of the material. When the moisture contained in the material is large, the material is easy to adhere in the crusher, and is also easily blocked during the feeding process, resulting in a reduction in crushing capacity.
  • 4. The fineness of the material after crushing. The fineness requirement is high, that is, the finer the material required to be broken, the smaller the crushing ability.
  • 5. The composition of the materials. The more fine powder contained in the material before crushing, the more it affects the crushing, because these fine powders easily adhere to affect the transport. For the content of fine powder, it should be sieved once in advance.
  • 6, the viscosity of the material. That is, the greater the viscosity of the material, the easier it is to adhere.
