productivity calculation of aggregate crushers jaw crusher and impact crusher

Introduction

The following article is based on a study done to find out the most productive crushers – jaw crusher and impact crusher. The article explains in detail how the research was conducted and what factors they took into account while calculating productivity.

Types of aggregate crushers

There are two basic types of aggregate crushers: jaw crushers and impact crushers. Jaw crushers are typically used for primary crushing, while impact crushers are used for secondary crushing or tertiary crushing. Each type of crusher has its own unique advantages and disadvantages, so it’s important to select the right crusher for your specific needs.

Jaw Crushers

Jaw crushers are typically used for primary crushing. They use compressive force to break up material into smaller pieces. The main advantage of jaw crushers is that they are relatively simple to operate and maintain. Additionally, jaw crushers often have a smaller footprint than other types of aggregate crushers.

Impact Crushers

Impact crushers are typically used for secondary or tertiary crushing. They utilize counterblow bars to crush material into smaller pieces. Impact crushers provide a more efficient method of crushing than jaw crushers because they generate more consistent sizes and produce less fines. Additionally, impact crushers often have a lower purchase price than other types of aggregate crushers.

Comparison between jaw crusher and impact crusher

When it comes to choosing the right crusher for your operations, you need to first understand the difference between these two types of crushing equipment. Jaws crushers work by compressing materials between two plates, one of which is movable and the other stationary. Impact crushers work by striking materials with blow bars that are mounted on a rotor.

So, which type of crusher is best for your application?

If you are looking for a crusher that can handle tough materials like granite or quartzite, then a jaw crusher would be a good choice. If you are crushing softer materials like limestone or coal, then an impact crusher might be a better option.

It all comes down to your specific needs and what you are hoping to achieve with your crushing operation. Talk to your crushing equipment dealer about which type of crusher is right for you.

How to calculate the aggregate crushing productivity

There are various types of crushers available for crushing aggregate. However, the most commonly used crushers are jaw crusher and impact crusher. While both these crushers are designed for crushing aggregates, they have different methods of working.

The jaw crusher works by compressing the aggregate against a fixed jaw. This results in a reduction in the size of the aggregate. The impact crusher works by impacting the aggregate with high speed rotating hammers. This results in a reduction in the size of the aggregate as well as shaping it.

To calculate the aggregate crushing productivity, we need to know the following parameters:
– The feed material size
– The crushed product size
– The rotational speed of the crusher
– The number of hammers on the rotor

With these parameters, we can calculate the crushing productivity using the following formula:
Productivity = (1/2) x Rotational Speed x Number of Hammers x Feed Material Size x Crushed Product Size

The factors that affect the jaw crusher productivity

Theoretically, jaw crusher productivity depends on the size of the feed opening and the crushing cavity, as well as the strength, hardness and composition of the material to be crushed. All these factors affect not only the capacity of the crusher, but also its power consumption. The following are some specific examples.

A. The feed opening width: If the feed opening width is increased, all other conditions being equal, the productivity of jaw crusher increases as well. But at the same time, power consumption will increase accordingly because more material will be crushed in a given unit of time thus requiring more power.

B. The feed opening depth: If all other conditions are equal except that the feeding depth is increased by 1 cm, the productivity of jaw crusher will be reduced by 5-10%. This is because when the feeding depth is increased, the cross-sectional area of ​​material to be crushed in unit time decreases which reduces productivity.

C. Material hardness: The harder the material to be crushed is, the lower is its productive capacity but at the same time power consumption will be higher than for softer materials.

The factors that affect the impact crusher productivity

The first thing you need to understand is that the term productivity is relative. When we say that an impact crusher is productive, we compare its output with the output of other similar machines. For example, if we want to know how productive a jaw crusher is, we compare its output with the output of other jaw crushers.

There are several factors that can affect the productivity of an impact crusher:

The size of the feed material: If the material is too large, it will not be crushed by the impact crusher. The smaller the material, the more productive the impact crusher will be.

The hardness of the feed material: If the material is too hard, it will not be broken by the impact crusher. The softer the material, the more productive the impact crusher will be.

The moisture content of the feed material: If the material is too wet, it will not be crushed by the impact crusher. The drier the material, the more productive the impact crusher will be.

How to improve the productivity of crushers

There are a number of ways to improve the productivity of crushers, and here are some tips that may help you achieve this goal:

1. Make sure that the feed material is properly sized.
2. Adjust the settings of the crusher to match the material and desired output.
3. Inspect the crusher regularly to ensure that it is in good working condition.
4. Train operators on how to properly use and maintain the crusher.

Conclusion

The article has discussed the productivity calculation of aggregate crushers jaw crusher and impact crusher. It is important to note that the productivity of any crushing plant depends on several factors, including the type of crusher used, the feed material, the size of the feed material, and the operating conditions of the plant. However, by following the tips outlined in this article, you can maximize your plant’s productivity.
