Since the birth of cone crusher in the early 20th century, it has experienced successive stages of historical development such as Simmons cone crusher, bottom single-cylinder hydraulic cone crusher, high-energy hydraulic cone crusher, and ultra-fine crushing cone crusher.
In these stages of development, cone crushers are widely used in mining ores crushing, metallurgical industry, chemical industry, construction industry, cement industry and sand and gravel manufacturing industries to handle medium and fine crushing of hard rock materials.
Cone crusher has become the mainstream crushing equipment in the mining industry because of its good equipment performance and low cost of use. Today, Bellian mining machinery manufacturer will take you to understand the relevant knowledge of cone crusher and how to use cone crusher to improve production capacity.
1. Classification and advantages of cone crusher
At present, cone crushers are mainly divided into single-cylinder cone crusher, multi-cylinder cone crusher, full hydraulic cone crusher and Simmons cone crusher.
Before the reform and opening up, Simmons cone crusher was widely used due to its low price due to technical, capital and other reasons. In recent years, with the advancement of science and technology, economic development and policy guidance, efficiency, safety and environmental protection have become mainstream trends, and single-cylinder and multi-cylinder hydraulic cone crushers are gradually welcomed by users.
The SC single-cylinder cone crusher produced by Bellian Machinery adopts the design concept of constant cavity type, which makes the lining plate have a long service life. As a "hard rock nemesis", it has the advantages of large production capacity, high crushing efficiency and low energy consumption; while HPM has more Cylinder hydraulic cone crusher adopts laminated crushing cavity design, hydraulic motor adjusts the discharge port, precise control, so that the product size is uniform and the quality is excellent.
2. How to use cone crusher to maximize production capacity?
After you choose the cone crusher, how to use the cone crusher to maximize the production capacity is the concern of many sand and gravel manufacturers. After all, how much sand and gravel is produced means how much wealth is produced. The following will tell you how to improve the production capacity of cone crusher from 5 aspects.
1) Keep the parameters of the discharge port on the tight side unchanged
In order to stabilize the output, quality and production line load of sand and gravel products, the first thing to ensure is that the parameters of the discharge port on the tight side of the cone crusher remain unchanged. Otherwise, it is easy to cause an unexpected increase in the particle size of the product, which in turn affects the entire production line system and the final output.
It is recommended to check the parameters of the discharge port on the tight side every shift to ensure production capacity.
2) Try to ensure "full cavity" operation
If a cone crusher is "starved" and "full" due to factors such as unstable feeding, then its product particle shape and product rate will also fluctuate. For the cone crusher operating in half cavity, its products are not ideal in terms of gradation and needle-flake shape.
It is recommended that sand and gravel manufacturers try to ensure that the cone crusher runs in full cavity to obtain better throughput and grain shape.
3) Feed evenly, not too little
Uniform feeding is an important factor to ensure stable production capacity in production. If only a small amount of raw materials are given, it will not reduce the burden of the cone crusher. On the contrary, too little raw material will not only damage the output of the product, the grain shape will be poor, but also have an adverse effect on the bearing of the cone crusher.
In order to obtain proper "load bearing positioning" and maximize productivity, the actual power of the cone crusher should be kept between 40%-100% of the rated power, and 75%-95% of the rated power in operation is the best choice.
4) The feed drop point is aligned with the center point of the feed port
It is recommended to use a vertical deflector to guide the feed drop point at the center of the cone crusher feed port. Once the drop point is eccentric, one side of the crushing cavity is full of material and the other side is empty or less material, which will cause adverse effects such as lower crusher throughput, increased needle-like products, and oversized product particle size.
5) Accurately grasp the three design upper limits
There are three design upper limits for cone crushers: upper limit of throughput (capacity), upper limit of power, and upper limit of crushing force.
When the crusher is operating at maximum throughput, the actual power and crushing rate are still slightly below the upper limit. Operation beyond the upper limit of rated power and crushing force will cause overload and permanent fatigue damage to the cone crusher. This damage is irreversible and will continue to accumulate, ultimately shortening the service life of the cone crusher.
In fact, in the long run, in addition to the above five skills, the life span of the cone crusher is also an important aspect that affects the production capacity.
3. Factors affecting the service life of cone crusher
Enough to buy equipment costs, we all hope to extend the service life of machinery and equipment, so as to increase production capacity and maximize economic benefits. So what factors will affect the service life of the cone crusher?
1) Stone powder content and stone moisture
When the cone crusher is working, if the stone powder content and humidity of the material are relatively high, it will easily adhere to the crushing wall and the rolling mortar wall during crushing. Over time, it will not only reduce the production efficiency, but also affect the crushing wall and rolling mortar. Walls corrode, reducing their service life.
2) The hardness and particle size of the stone
The higher the hardness of the material, the more difficult it is to break, the greater the impact load on the crushing wall and the rolling mortar wall in production, and the correspondingly shortened service life; when the particle size of the material is larger, the more serious the wear of the lining plate, the service life of the crusher. will also be shortened.
3) Quality of broken wall and rolled mortar wall
A high-quality wear-resistant fitting has high requirements on the surface of the casting. The casting is not allowed to have cracks and casting defects such as slag inclusion, sand inclusion, cold insulation, pores, shrinkage cavities, shrinkage porosity that affect the performance. . As the core components of the cone crusher - the crushing wall and the rolling mortar wall, their quality directly affects the capacity and life of the crusher.
