Golden Machinery has introduced a new material processing method and provided ore Screening Equipment. Our ore screening equipment facilitates mining, quarrying and recycling operations. Different types of sensors and machines cover a large number of ore and mineral types, using ore dressing equipment to concentrate and reduce costs.
Ore classification relies on the use of some form of sensor to measure the different properties of valuable and waste components. The physical separation of particles is by changing the particle trajectory of the product or waste with precision air jets. In existing business with fixed equipment capabilities, the concentration can be created in small or remotely utilized beneficiation equipment due to the low cost of mining equipment that adds ore grade. Increase productivity after sorting. It can reduce the size of downstream processing equipment, reduce capital and operating costs, or increase productivity.
The entire production line can be planned in a semi-motorized form, including crushers, screens, belts and sorters. Due to the disposal of waste rock on site, transportation costs can be greatly reduced. In addition, due to the considerable ore content, concentrates can be used to obtain higher prices.
The ore sorting solution replenishes and relieves the burden of downstream stages of conventional processing. This greatly reduces the overall cost of process materials such as water leaching agents, while material recovery facilities can be made smaller because waste rock is no longer disposed of.
In addition, by improving grade control, bulk ore sorting can reduce lean and ore losses during mining. In some cases, mining costs may be reduced, while the selectivity offered by bulk ore sorters allows for less selective mining processes. In order to be used for enrichment, it should be applied to a large amount of ore, such as on a truck pallet or a full load conveyor.

Concentrate the ore with mineral processing equipment to reduce process costs. Vibrating screen equipment, like the automatic center vibrating screen, is widely used in mining, coal, petrochemical, water conservancy, electric power and other industries. The following Zhejiang Golden Machinery Factory introduced different Screening Equipment.
The spring is the support for the screen box and acts as a buffer and protector. According to the principle, the self-centering vibrating screen can be divided into two types: bearing eccentric type and pulley eccentric type. According to the classification of the support structure, it can be divided into suspension self-determination.
Each application is unique in its screening needs, although each application relies on its screening media to successfully separate materials. Popular screening media include woven wire cloth, polyurethane, rubber or polyurethane and steel wire cloth or a combination of polyurethane and rubber. Each screen media offers producers different options in terms of productivity and efficiency, and efficiency is the key to creating a fast return on investment.
A resonant screen is a shielding device that operates in a resonant state. The utility model has the advantages of large processing capacity, high screening efficiency, compact structure, simple transmission mechanism, stable operation, low energy consumption, easy adjustment of amplitude and frequency, and low noise. The disadvantage is high manufacturing precision, uniform ore and low price. Resonance screens are mainly used for screening, dewatering, desliming, and de-intermediation in coal preparation plants, and are also used in a few metal ore dressing plants.
Heavy-duty vibrating screen: This vibrating screen is relatively strong and can withstand large impact loads. Suitable for screening large or dense ores with a maximum mass of 400 mm. This machine can replace the bar screen which is easy to block as the screening device before the crushing. It can also be used as a cleaning device for large ore with a large amount of mud. In recent years, such vibrating screens have been widely used in many large foreign concentrators before being crushed. The sieving machine is multi-layered for screening the final product, which not only improves the crushing capacity, but also reduces the impact of the water-rich powder ore on the crushing operation.

Sludge concentration is an effective method to reduce sludge moisture content and reduce sludge volume. The sludge concentration mainly reduces the interstitial water of the sludge. Thickening Tank can be used to treat sludge, and gold machinery takes you through the process of sludge treatment.
Working principle of sludge concentration tank: According to the pressure of the dewatering zone, the whole dehydration process can be divided into three parts: pre-dewatering zone, pressure dewatering zone and pressure forced dewatering zone.
First, the slurry is evenly distributed through the pulper to the pre-dewatering zone on the web and then into the gravity dewatering zone. In this area, the sludge relies mainly on its own gravity to remove most of the water, which makes the slurry lose fluidity and the dewatering concentration is increased to 3-5%. Dewatering is then continued on the surface of the web, and the slurry enters a wedge-shaped intersection formed by the middle and lower webs, i.e., the pressure dewatering zone.
In this area, the slurry is gently squeezed by the middle and lower sieves, dewatered to about 15-20%, and then into the pressurized dewatering zone. The pressure dewatering zone consists of eight dewatering rolls of different diameters, allowing rapid dewatering on both sides of the screen during the extrusion process. The diameter of the dewatering roller is changed from a size change to a change in the angle of the filter to ensure that the dewatering pressure is continuously increased and a corresponding shear force is generated, which is finally scraped off by the doctor blade. The filter-removing filter is washed with high pressure water and then passed to the next working cycle.
High-efficiency concentrating tank: The function of the high-efficiency concentrating tank is no longer a simple material settling. It is a new solid-liquid separation device that integrates sedimentation and mud filtration. Before entering the high-efficiency concentrator, the slurry is removed by a gas removal device, then fed into the mixing device through the feed pipe, and the slurry is mixed with an appropriate amount of flocculant to form a good flocculation structure in the mixing device, The way to diffuse into the surrounding environment enters the pre-formed sludge layer from the bottom of the concentrating tank.

High-efficiency Thickening Tank are also called thickening tanks. Compared with traditional concentrating tanks, concentrating tanks have the characteristics of deep cones, and the height of equipment is significantly higher than other concentrating tanks. The machine is mainly composed of a deep cone, a feeding device, a stirring device, a control box, a drug delivery device and an automatic control system. So what is the difference between the principle of concentration and ordinary concentrating tanks? Zhejiang Jinji Factory will take you to understand.
Generally, in order to obtain a good compacting effect, it is necessary to go through three indispensable stages, namely, a coagulation destabilization stage, a coagulation granulation stage, and a filtration compression stage. If the flocculation is insufficient, the solid-liquid separation will not achieve the desired effect.
The same is true for effective concentrating tanks. The slurry is flocculated in a concentration tank. After the large flocs in the slurry are increased to a certain amount, the bottom of the thickener forms a desired dense phase layer. The slurry is subjected to the pressure of the squeegee, further concentrated, and then discharged through a discharge port. At this time, the pulp is already a high concentration concentrate, which can be further filtered, and at the same time, the tailings with higher concentration are discharged, which greatly improves the recovery rate and helps the enterprise to achieve an efficient production mode.
The bottom of the concentrating tank is usually designed to have a certain taper. Under the continuous scraping action of the squeegee, the deposit to the bottom of the concentrating tank moves to the center of the tank bottom and is finally discharged from the discharge hole at the center of the tank bottom.
