High-efficiency and environmental crushers can improve the efficiency of the whole crushing line and the performance of the finished products, bring more profits to enterprises and save more operating costs. But do you know how to choose the suitable crushing equipment?
High-efficiency crushing site
This article will share with you four important factors about purchasing crushing machines and give you some references from all levels, hoping you can get some ideas here.
Economic indicators
Upfront expenditure
The upfront expenditure mainly refers to the necessary investment in the previous stage for the normal operation of crushing machines, such as the costs in the employment of technical personals, the treatment of workers, the package of crushing machines and authentication for projects.
Crusher price and payment methods
The prices of machines and the payment methods are the main considerations that enterprises with tight funds paid much attention to. It directly influences the continuity of projects.
Factors affecting the price of crushing equipment
In general, the prices of crushing machines are affected by many factors, including:
The invested costs
The manufacturing costs directly influence the prices of products. The research, development, design, and production of crushers need many labors and materials. Therefore, the higher the manufacturing cost, the higher the price.
The nature of manufacturer
There are a lot of manufacturers in the current market, and the nature of different manufacturers is different. Some of them are manufacturing-type enterprises, some of them are middlemen, and others are distributors.
The prices in different types of enterprises are totally different. Relatively speaking, the products in self-marketing enterprises are more reasonable.
The quality and performance of machines
Equipment with high quality, stable performance, and low failure rate can bring more profits to enterprises, but it has high producing costs which makes itself a high price. Correspondingly, the equipment with low quality has less investment and low prices.
Therefore, more comparisons are required so that to choose a reasonable crushing machine.
The regional differences
Prices in different regions are definitely different because the economic levels in different areas are different.
In developed countries, people have the ability to afford expensive equipment, and the price of the crushing machine is much higher; on the contrary, the price of machine in developing countries is cheaper.
Therefore, compared with Europe and other regions, the crushing machine in Asia is much cheaper.
In terms of payment methods, the companies generally accept the T/T(Telegraphic Transfer), L/C(Letter of Credit), and other payment terms also can be negotiated.
The expense of installation and removal
The installation and removal in the crushing site
The expense includes the costs of installation, removal, cleaning, etc. Among which the installation expense consists of the costs of purchasing steel, cement and other building expense, labor costs, etc.
If the project has a long working period and the work site is relatively concentrated, the fixed crushing equipment is recommended; while the project with a short construction period and scattered work site, especially road construction should be better to choose the mobile crushing plant.
Mobile crusher can move flexibly no matter for the transferring project or the working site removing, which is a cost-effective crushing machine.
Operational expense
The working-shift cost, holding-shift costs, maintenance costs and the running costs should be included in the operational expense.
When choosing crushers, the crushing equipment with oil and electricity engines should be the first choice. The crushing machines can usually work relying on the power generated by electric energy.
Mobile crushing plant with oil and electricity engines
In the case of no electricity, power failure or voltage instability, the diesel power generation system can be used to ensure continuous operation, so that the crusher can work high-efficient and bring more profits.
Technical indicators
Reliable operation
The reliable operation is one of the important factors evaluating the performance of crushing machines. In general, the crusher is required to continue working 1500 to 2000 hours without any fault.
If the working environment is terrible, the reliability is more necessary.
Manufacturing techniques
HXJQ possesses more than 600 digital processing equipment
Excellent techniques are the prerequisite of guaranteeing reliable operation, which reflects and measures the technologies and management of the manufacturer.
When choosing crushing equipment, its manufacturing techniques should be fully considered, so that to ensure the stable operation.
Working efficiency
The working efficiency is one of the important parameters when choosing crushing machines, which determines the crusher of positive capacity or negative capacity.
There is a certain difference between actual capacity and theoretical capacity, and the actual capacity is changed when the materials' nature, strength, hardness, specification and others change.
Therefore, the theoretical capacity of machine should be higher than the required average capacity to guarantee sufficient capacity.
Automatic degree
Automatic degree is the basic indicator reflecting the technical level of crushers. Meanwhile, the automatic degree reflects the developing level of the whole manufacturing enterprises.
Automatic degree of crushers
A crushing machine with a high automatic degree can save a lot of labor costs and bring more profits to the enterprises.
Product indicators
Nature of stone materials
Stone types: the representative material is selected to analysis the lithofacies and chemical components and identify species of stones. Stone types are such as limestone, granite, basalt, andesite, quartz gypsum, river pebble, gold ore, copper ore, iron ore, etc.
Strength: it usually refers to the compressive strength, which is divided into super-hard ore (160 to 250 MPa), hard ore (100 to 160 MPa), inferior-hard ore (100 to 140 MPa) and soft ore (less than 40 MPa).
For the super-hard and hard stones, it is better to use jaw crusher as the primary crushing machine, cone crusher as the second crushing machine; while for the inferior-hard and soft stones, it is recommended to use the impact crusher or hammer crusher as the secondary crushing machine.
Hardness: it usually refers to Mohs' hardness, indicating the mineral's resistance to foreign mechanical action.
Water content: it is usually required no less than 2% and no more than 5%.
Silt content: it is usually required no less than 1% and no more than 2%.
Stone size: in general, the size of the material should be less than the feeding size of the crushing machine, so that to prevent the wearing parts from abrasion.
If the size of materials is too large, jaw crusher is recommended to be the first crushing machine; if the discharging size is required strictly, a crushing line consisting of several crushing machines is needed.
For example, jaw crusher can combine with cone crusher, impact crusher, or hammer crushing to building a complete crushing line, so that to improve the grade of finished products.
Feeding method: it should be considered so that to choose the supporting feeding equipment.
Required finished product
Whole output
In general, it is evaluated by the standard of capacity within an hour. If it is calculated by the annual output or the monthly output, the working days per year and daily working time should be confirmed to ensure the workload per hour.
Grade requirement
There are several specifications such as 0 to 5mm，5 to 15mm，15 to 25mm，25 to 40mm. According to the requirements of construction, the grade of sand and gravel should be determined to choose suitable crushers and screens.
Different specifications of finished products
Particle requirement
The content of needle-like particles should be considered to choose the suitable crushing equipment.
Manufacturer
Source and supply channel
If the product is rented, the source refers to the renting channel, and if the product is purchased, the source means the agency or the manufacturer of crushing equipment.
When choosing the crushers, it should be compared to the regional differences (such as Asia and Europe), the development of the market, the maintenance of crushing machines and the supply channel of products to get a better choice.
Delivery period
In principle, the supply and delivery period should be as soon as possible. But for the customized crushing equipment, the manufacturer should have sufficient time to produce under the premise of not affecting the progress of the whole project.
