Mine processing equipment includes all kinds of crushing equipment and screening equipment. The crushing equipment is divided into jaw crusher, impact crusher, cone crusher, sand making machine, etc. It is mainly used to process the mined ore like limestone, bluestone, granite, iron ore into stones of different specifications. The screening equipment includes vibrating screen, sand washing machine, feeder, etc., which are used to separate various minerals from other impurities and materials. Choosing the right mine crushing equipment can effectively improve production efficiency and bring more benefits, but in fact, some users usually choose second-hand equipment as one of the options when purchasing mine crushing equipment. Is it possible to buy second-hand equipment? There are advantages and disadvantages of second-hand mine crushing equipment for your reference.
Second-hand mine crushing equipment is not recommended to buy. The reasons are follow：
Reason 1: The market is not yet mature.
At present, due to the influence of the national economic system and relevant guiding policies, the domestic second-hand market has not yet matured and is still in the developing stage.
Reason 2: Circulation is mostly personal transactions.
Most of the circulation of second-hand equipment is for personal transactions, and there are only a few trading institutions and venues, lacking necessary market supervision and management guidance.
Reason 3: Equipment is difficult to evaluate.
The quality of second-hand equipment is mixed, and it is impossible to judge its quality. Therefore, there may be a situation where a small number of obsolete equipment is simply refurbished and replaced, and then it enters the market for trading.
Reason 4: after-sales problems
Second-hand equipment dealers do not necessarily have after-sales service conditions for the equipment.
1. The consumption of wearing parts
Mining crushing equipment is a kind of high-loss equipment, and the wearing parts of the equipment need to be replaced frequently, such as the main wearing parts such as the stationary jaw plate and the concave. The sizes produced by different manufacturers are different, and it is difficult to completely match if there is a slight difference. In addition, some non-standard wearing parts in mine crushing equipment may be difficult to find, which will cause shutdowns, delay production progress, and greatly reduce production efficiency.
2. The source of the device is unknown
Signage may be mislabeled, and the source of its equipment cannot be guaranteed.
3. The use of the equipment has not yet been explained
Usually, after choosing mine crushing equipment, you need to understand how to operate, maintain and deal with common faults, etc. These require operators to undergo professional training before they can get started. Second-hand equipment usually has no equipment usage specifications and no professional engineer training and guidance, there is no equipment manufacturer after-sales maintenance, so some problems are prone to occur.
4. Other situations
Users who choose second-hand equipment cannot know its usage. There may be many hidden factors inside the equipment, which will greatly reduce its service life and increase the risk of damage.
The disadvantage of second-hand mine crushing equipment is that it has certain advantages in price, but it is a big expenditure in terms of post-maintenance alone. Therefore, in the long run, the new type of mine crushing equipment is more ideal. It is recommended that users conduct on-site inspections when purchasing mine crushing equipment, and choose regular manufacturers with strong strength and perfect after-sales service.
