Mobile crushing station as material crushing and conveying equipment in mine, building materials, construction and other projects abroad has been widely used in domestic and foreign manufacturers and product specifications and more.
For large equipment, must address the following questions:
1. The yard layout
As a kind of large equipment, mobile crushing equipment have higher demand to the venue and location.
2. Mobile
As construction equipment, the programming of the flexible mobile requirements must be fully reflected, improper use can cause in mining and broken and in the process of mining drop period, production time and can not get effective guarantee.
3. The security
During the equipment work and drill blasting operations effectively cohesion, solve the equipment safety and process design of the relationship between continuous production equipment normal use.
4. The field plan and loading equipments
Early in material field due to the relatively small, the broken equipment and dig the difficulties faced by the early stage of the loading equipment can play advantage is, but when the field is open, the subsequent transport equipments is directly related to whether the programming of the key to smoothly.
Main technical measures of mobile crushing plant:
1. The set of mobile crushing station in the yard
Mobile crushing station in yard arrangement is the key in application, mobile crushing station is play efficiency, improve the production efficiency, reduce operating costs, the key to demonstrate its superiority. Mobile crushing station by stope in stope layout of the terrain, mining area, the blasting technology, digging equipment, follow-up transporting conditions, can have a variety of arrangement. According to the mobile crushing station in some engineering application examples, can be roughly divided into the following arrangement:
A, mobile crushing station layout in slip wellhead, dump truck haul discharging into the crushing station, stone after crushing directly discharged into the chute.
B, mobile crushing station layout in the yard, dump truck transport feeding, stone after crushing by subsequent semi mobile belt machine transportation.
C, mobile crushing station layout in the field of mining face, excavators loading it directly to the material, after the broken stone by mobile belt machine and the subsequent half mobile belt machine, stationary tape to semi-finished products storage area.
For A, B two kinds of arrangement, in the implementation of the transport stone, still need to dump truck can’t exert better the advantage of mobile crushing station. But under certain conditions, the use of these two kinds of arrangement, is necessary and feasible.
2. Mobile crushing station and dig with the device
Combination of two kinds of equipment for the feeding of dump truck has a certain advantage, and able to feed, transportation of broken stone also has a very good effect. When feeding dump cars, because of the limitation of discharge position need wait a car after unloading the material out, next car registration discharge. In this way, there is a discharge intermittent time of operation. And because the car can only be stone relief in the crusher into the hopper of the machine, and by the bar feeder crusher feed, and the length of the bar feeder is 5000 mm so stone after feeder to crusher is also a time. These factors caused the auto feed, mobile crushing station of the production capacity of relative decline. Using excavator directly to the crushing plant feed, mobile crushing plant production capacity is increased.
3. The mobile crushing station blasting safety protection
This way of application in the field of mining blasting design and the commonly used open yard before blasting design requirements are basically the same. There are two related but ask body needs special attention. The first is to avoid blasting slungshot for crushing plant and tape machine damage. The second is a generous amount of blasting as far as possible, to reduce the mobile crushing station and mobile belt machine blaster frequency shift. Mobile crushing station is applicable to decorate in the yard and broken equipment, so in the design of the whole machine, in the field of planning, equipment of mobile and blasting technology, has a blaster protection problem.
Has the function of the equipment design, the design of the crawler walking mechanism, to make the mobile crushing station can easily shift, can to blasting safety zone. Between two tape machine, tape machine and crushing plant with connection is the connection between rotary splicing mechanism, between the two tape machine in the horizontal direction can be folded down to 300 °, and the tail end of the discharge hopper can roll shift in orbit. The mobile mechanism design, making mobile crushing station can better meet the needs of the shift of the blaster.
Conclusion:
After above steps, in the actual construction constantly adjust and perfect, the mobile crushing plant from the technology has been resolved. But considering the equipment must be imported, the investment is bigger, and used as the first time, inadequate understanding of the reliability of the equipment operation. So the equipment efficiency and operation is one of the biggest factors restricting equipment applications.
