Mining Equipment Wet Grinding and Classifying Plant for Mineral Processing
Crushing Circuit and Equipment
The crushed ores must to be grinded to meet the liberation condition to meet the next operation stage.
Wet grinding is often used in the mineral processing plants to improve efficiency, reduce consumption of energy and steel materials, and avoid over-comminution. According to the plan of grinding product size and capacity, grinding flowchart should be designed reasonably, and grinding machine is properly selected according to the size of ore and other properties.
Common grinding process may be one stage, two- stage or three stage. There are open circuit or closed circuit in grinding circuit. Closed circuit process is generally used to control grinding product size.
The common first stage grinding machines are AG mill, SAG mill, rod mill or ball mill and so on. The second and third stage grinding machines often use ball mill and others.
The common equipment which combine with grinding system to be closed circuit aretrommel, vibrating screen, spiral classifier or hydrocyclone.
Grinding Circuit Examples
Many kinds of the designed grinding circuit are suitable for different processing plants. Three circuit examples of crushing plants are following.
SAG mill - ball mill closed grinding circuit
Two stages of ball mill closed grinding circuit
One stage of ball mill closed grinding circuit
Supplied Equipment and Services
HZE supply a complete set of solution for the grinding plants with small scale, medium scale or large scale, which included engineering design, equipment manufacturing and supply, logistics, installation, commissioning, training, trial production and so on to ensure advanced technology, perfect processing, efficient plant construction, reduced investment, environmental protection and maximum benefits.
1. What is the main business scope of your company?
HZE is a company with R&D center, design institute, manufacturing factories, installation and commissioning teams. Our customers are in the mining and mineral processing fields. Our major businesses include mineral processing EPC (engineering, procurement and construction), project consultation, engineering design, mineral processing equipment manufacturing, on-site installation, commissioning, staff training, customer project operation management, spare parts supply and technical support. Customers are free to choose any one or any combination of our services.
2. What are the outstanding advantages of your company?
The one-stop service of mineral processing engineering project and equipment is our core competitiveness.
The most important feature that HZE distinguishes itself from other engineering companies, design companies or consulting companies is that we are also an equipment manufacturer with a production plant of 50,000 square meters, and we have complete manufacturing rout and the related equipment.
HZE distinguishes itself from other equipment manufacturers by owning its own R&D center and engineering design institute.
HZE distinguishes itself from many mining machinery enterprises by possessing an expert team with members including not only senior engineers of the company, but also top Chinese technical experts, university professors and researchers.
3. What are the characteristics of your company's 3D design?
HZE not only uses 3D software to design equipment, but also uses 3D software to design process flow, pipeline, steel structure, auxiliary facilities, etc. of the whole mineral processing project. We even use 3D design for equipment packaging, container packing and equipment instructions manual. This greatly improves the quality of equipment and engineering, shortens the construction period, facilitates technical discussion and evaluation, facilitates project management, improves construction safety and reduces project cost.
4. What are the service features of your company?
- Customers who whether buy our equipment, or entrust us with EPC, or require us to provide a certain service, cooperate closely with us to carry out specific operations and supervise our implementation throughout the process.
- HZE will try to understand the basic situation and needs of customers as detailed as possible before the sale, formulate a preliminary plan according to the specific situation of customers, and get unanimous opinions after communications and discussions with customers to determine the plan.
- We set up customer files for every customer who signed the contract with us and upload them to the Cloud where customers can also get an account and password. Customers can have all the documents, videos and pictures, technology, services, execution, operation, management and control, maintenance and so on related to the business.
- Whether it is in the process of general contracting, equipment manufacturing or providing some kind of service, we welcome customers to know about our implementation on the spot or through the network, and put forward requirements and opinions.
- We assist users who have used our products to formulate operation specifications and make suggestions on maintenance plans and spare parts inventories. In addition to routine on-site installation, commissioning and training, during the production period after we handing over equipment to customers for use, we often understand the equipment using situations through the network and provide guidance and training to customer management and operators.
- For the clients who have just start the mining business, we provide the opportunity of training and practice in China's mines for the clients' employees, until they are skilled in operation and maintenance.
