Product Description

Mineral Processing Plant Solid-Liquid Separation Equipment Thickening Rake Clarifier



Working Principle
The thickener is a machine that separates liquid from solids. It is defined as a method of continuous dewatering of a dilute pulp, wherein a regular discharge of a thick pulp takes place which is of uniform density, concurrently with an overflow of clarified solution. The solids particle size range in thickeners is generally from 0.5 mm to a few microns. Thickeners are often rated on kg of solids per square meter of surface area.
Briefly, its functioning can be explained with the rake that is driven in a thickener, which rotates slowly over the bottom of the tank, and slopes down towards the centre and moves the materials settled on the bottom to a central discharge.
The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well. The clarified liquid overflows a weir, while the solids which settle at the bottom of the tank are withdrawn as a thickened pulp from an outlet at the centre. Several rotating radial arms are assembled on the rake frame in the tank, from each of which are suspended a series of blades, shaped so as to rake the settled solids towards the central outlet.


Features
The degassing box is equipped to avoid the solid particles attaching to the bubbles remained in the feeding pulp which settle as the parachutes.
The outlet end of the feeding pipe is installed below the solution level to avoid air mixing the pulp during the feeding.
The stop baffle disc is amounted under the bottom of the feeding well and it is more than 1 meter under the solution level in order to ensure the uniform feeding and avoid the pulp flow destabilize the clarification layer.
The inner overflow weir is equipped to cause the clarified solution flows along the designed route to prevent the short circuit so that the sedimentation area is enlarged much.
The circular overflow weir in saw tooth shape causes the overflow uniformly flows out of every position.



Application
The thickeners are generally used in metallurgical field with the purpose of thickening prior to agitation, filtration, in the countercurrent washing of cyanide slime, and more thickening ahead of floatation, for dewatering tailing to recover the water for reuse in the mill and for thickening concentrates.
The thickeners are widely used in various industries including mining, coal, chemical, industrial, environmental (wastewater management), municipal and paper industry.

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?

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
