五.The four big feeder how to choose
When selecting a feeder, a number of factors need to be considered to ensure that you select the best equipment for a particular application scenario. Here are some considerations for selecting one of the four major feeders:
1.Selection according to application scenario
For large-scale jigger, priority can be given to Lg type chain feeder. It can feed the material evenly along the full width of the jigger, which is especially suitable for large and medium-sized jigger to improve the washing effect of the jigger.
For the scene that requires large feeding capacity and can withstand the impact of large materials, reciprocating feeder or heavy vibrating feeder can be chosen. Reciprocating feeder has large feeding capacity and can meet the demand of large-scale production. Can deal with particle size up to 2m of material, can withstand a lot of pressure warehouse and withstand a certain impact of large pieces of material, but also can transport hot materials and even up to 500 – 1000 ℃ baked lump ore, can be arranged in an oblique position, low noise.
Heavy-duty vibrating feeder is mainly used in coal mine washing, lime processing, ore processing, dock loading and unloading, aggregates, glass, cement, wood products and iron and steel industry and other fields. They are characterised by high productivity, strong environmental adaptation, high load carrying capacity, vibration and noise isolation, and long service life.
For different mining operations, according to the nature of materials, site conditions, etc. to choose the right type of mining feeder.
Heavy plate feeder can be adjusted according to the speed of the chain plate, strong impact resistance, large ore feeding capacity, long service life, mainly used for large mines, coarse broken ore feeding. Light plate feeder is mostly used for rough breaking feeding in small and medium-sized mines.
Belt feeder to adapt to the large feeding volume of work, the application of a wide range of scenarios, is efficient, fast, smooth and vibration-free feeding equipment. For example, the belt feeder produced by Henan Shenggong Heavy Mining Machinery & Equipment Co., Ltd. has the features of small operating power, light weight, large feeding capacity, stable feeding capacity, convenient adjustment, low noise, small maintenance, and strong generality of parts.
2.Consider the material characteristics
If the material is sticky, for LG type chain feeder, it is necessary to pay attention to the prevention of material balling phenomenon, and it can make use of its function of pre-wetting the raw coal. For reciprocating feeder, the chain speed should not be too fast, so as not to cause material accumulation and clogging; if the material is viscous but the moisture content is very low, ordinary mining plate feeder can be. For heavy vibrating feeder, according to the viscosity and humidity of the material and other characteristics, choose the appropriate model to ensure smooth and stable feeding.
If the material particle size is large, reciprocating feeder and heavy vibrating feeder can deal with larger particles of material, which reciprocating feeder is generally used in the raw material silo, the particle size of up to 2m; Heavy vibrating feeder can be used in the field of ore processing, adapting to different particle size of the ore. For mining feeder, heavy plate feeder impact resistance, suitable for processing large particle size materials, while light plate feeder is suitable for small and medium-sized mines coarse crushing feed, processing relatively small particle size materials.
3.Consider the production requirements
Feeding capacity requirements: if the production needs a large feeding capacity, reciprocating feeder feeding capacity, foreign countries have reached 12000t / h, the domestic has reached 5000t / h; heavy vibrating feeder also has a high capacity for mining feeder, different types of feeder feeding capacity is also different, such as heavy-duty plate feeder feeding ore, suitable for large-scale mines coarse crushing ore; belt feeder to adapt to the large amount of feed The belt feeder is suitable for large feeding capacity.
Feeding stability requirements: if you need stable feeding, for LG-type chain feeder, the use of frequency conversion speed control technology can be infinitely adjustable feeding volume, but the maintenance is relatively large. Reciprocating feeder feeding discontinuous, low productivity. Pendulum feeder in the mining feeder to feed a stable amount of ore, but the adjustment of the amount of feed trouble; heavy vibrating feeder to a certain extent can provide a more stable feeding.
In summary, the selection of the four major feeders need to take into account the application scenarios, material characteristics, production requirements, equipment costs and other factors, in order to achieve efficient and stable feeding operations.
