Vibrating Feeder Operating Principle:

Vibrating feeder is composed of vibrating body, spring, spring chassis, vibrating motor, and screen bar, vibration exciter which is formed by two eccentric shafts (driving shaft and driven shaft) and gear wheels.

Through the motors driving force carried by the triangle wheel, the upper gears of the driving shaft joggle and propel the driven shaft. At this time, the two shafts rotate in reverse at the same time leading to the vibrating of the machines funnel. Under the funnels vibrating, the materials will continuously move forward and some smaller ones will directly fall down the belt conveyor while passing the screening bar (there are some fixed spaces between those bars). Finally, the materials can be transported to the aiming place.

1.General Introduction of Flotation Machine:

Floatation machine is applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed.

2.Working Principle and Main Features of Flotation Machine:

Floatation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. There is self-control device on the surface of mineral slurry, so it is easy to adjust it. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurrry respectively.

Raymond mill is a common industrial powder equipment,and it's used to grind barite, limestone, ceramics, etc, such non-inflammable and non-explosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjustable in the range of 60-1250 mesh(It can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.
According to Raymond mill operating principle and working practice, we found that the main influence factors of Raymond mill's output mainly include:
1. One of the factors that affect the raymond mill's output:The hardness of the materials.The more hard the material,the more difficult to grind for the Raymond mill,and the more serious to wear for the equipment.The speed of the Raymond mill slow, of course,,the capacity of the Raymond mill is small.We recommend that customers use the equipment in daily process,should be strictly in accordance with the use of the Raymond mill's operating rules,don't use the equipment to crush the mateials that exceed the Raymond mill's ability.It's also the basic point of Raymond mill's use and maintenance daily.
2.The second factor that affect the raymond mill's output:The humidity of the materials,that is, if the raw materials contain water higher,the materials will easily adhere onto the Raymond mill, easily plug when the course of the materials being conveyed,so that causing the output of Raymond mill reduce.
3.The third factor that affect the raymond mill's output:The output size.The required size is high,that is the output size is smaller,the capacity is lower.If the customers have a high required of the materials’size,can according to their own production capacity and economic strength for other devices,such as YGM series High pressure micronizer.This machine have a wide range of product size,the smallest can reach to 2500 mesh.
4.The fourth factor that affect the raymond mill's output:the composition of material. If there is much powder in the raw material, it may reduce down the capacity. Because the powder will be easily to adhere.For this materials should be screened once in advance. For this situation, we recommend that customers should sieve the materials with the vibrating screen before the milling process.
5.The fifth factor that affect the raymond mill's output:The viscosity of materials.That is, the larger viscosity, it is easier to be adhesion.
6.The sixth factor that affect the raymond mill's output: The quality of quick wear parts (such as hammer,jaw plate). If the quick wear parts has no good wearlessness, it will reduce down capacity.
In short, there are many factors that effect the Raymond mill's outputand some are for the use of customer,for these factors,we have to continuously summarize,and timely evade,of course,there are some technical factors of the equipment itself.For these,it should be judged by themselves to make a right choice.

The types of rocks you are working with will have an impact on the type of equipment you need to get the job done.
Before buying equipment you need to take a long look at your rocks or ores and ask the following questions:
How hard is the material?
How abrasive is the stone?
How compressed is the material?
What size is the material you are crushing?
Before selecting any machinery, you need to find out if you are working with a hard and abrasive , material used to grind, smooth, cut, or polish another substance. Natural abrasives include sand, pumice, corundum, and ground quartz. Carborundum (silicon carbide) and alumina (aluminum oxide) are important synthetically produced abrasives. substance, like copper ores Copper ores may refer to:
Bornite
Chalcocite
Cuprite
Tennantite
Tetrahedrite
Malachite
, or a softer stone, like a limestone-type material.
While limestone, sedimentary rock wholly or in large part composed of calcium carbonate. It is ordinarily white but may be colored by impurities, iron oxide making it brown, yellow, or red and carbon making it blue, black, or gray. The texture varies from coarse to fine.
..... Click the link for more information. can be crushed by the same machine that is capable of crushing harder ores, it may be difficult for your crusher to deal with tougher material if it is designed for softer substances.
You need to ensure the crusher will be used so it reflects the type of material you are crushing. To do this, you should learn if you need a single or double toggle To alternate back and forth between two states.
toggle - To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from "toggle switches", such as standard light switches, though the word "toggle" actually refers to crusher.
Even though the majority of single toggle crushers are well built, due to the motion of the machine they should be reserved for use with soft and nonabrasive materials. Hard rocks and ores, those with 18,000 to 20,000 PSI, are more economically crushed in double toggle crushers.
This is because the wear factor with a double toggle machine is less than with a single crusher, which will work harder to crush stronger material. The double toggle is robust enough to deal with hard ores, and because of this, the life span of the machine is significantly greater than with the single.
You should also give consideration to how many tonnes of rock a day you expect to crush in the machine, and whether there will be a secondary, or even a third step in the process before the rock reaches its final size.
A decision will also need to be made as to whether you plan to filter out smaller material before or after the crushing process. Prior to entering the crusher, finger-like accessories can be installed to separate the smaller pieces of stone to prevent it from being crushed along with the larger pieces.
If you don't have these fingers, you may need a larger crusher because more material will be going through the machine.
When you purchase you will also want to decide whether to buy a portable or stationary plant to work with. Portables are more useful if you are a contractor going site to site, compared to a stationary plant, which is heavy duty, and is better if ore and rocks are being brought to a single site.
