Currently a Jaw Crusher is widely used in the country and hammer crusher for ore fragmentation pattern, after passing through the broken hammer crusher, go straight to the selected job. In fact, such practices caused enormous costs and waste of resources, we have analyzed and explained:

Existing problems:

1. dry separation efficiency is low, despite unusually severe, resulting in production cost and a huge waste of resources;

2. Hammer Crusher crushing capacity is limited, unable to provide good feeding for dry separator, hammer wear for very serious 3 days for a hammer;

3. function of Jaw Crusher is not deserved, wasting energy and does not form an effective shredder;

4. broken process layout is not reasonable, there are a number of material handling, construction machinery consume large amounts of production costs;

Problem analysis:

1. dry separation efficiency is low, despite unusually severe, resulting in cost and a huge waste of resources;

Seasoned in general have adopted open-loop design (no set return broken), into dry coal separator of granularity is not brought under control, lots of after blasting, transit, rough and fine break material (already has a huge cost), not magnetic in the dry, so it is waste thrown away in vain. Magnet is merely weathering of fines and a few pieces of fine material. Reasons leading to this consequence is that broken system is not able to provide enough fine, dry particle size has not been under control for the selected item, in jettisoning the waste actually contains a lot of iron.

If broken system can provide -10MM materials, then dry separation efficiency will be a substantial increase, would not have caused such a massive waste. Therefore, the ore must be broken up into -10MM, and then make the selected job. To achieve such a crushing effect, it must be made from the crushing technology and equipment research and configuration. Present a thick broken jaw (PE400*600, and PE500*750, and PE600*900) and hammer Crusher models fall short of such a finely requirements at all.

At present were thrown out in the mining area of the so-called “waste” is in essence a stacks of bills, which has been blasting and crushing to a certain size of iron ore contains a lot of iron, to crushing these materials selected job, would be a very convenient and low-cost, knowing that such information processing enterprises should pay attention to the.

2. the traditional hammer Crusher crushing capacity is limited, unable to provide good feeding for dry separator, hammer wear for very serious 3 days for a hammer;

Now commonly used traditional hammer-hammer crusher is a pose, which is unable to provide high speed impact crushing the required impact velocity, therefore crushing capacity is limited. Coupled with, currently General of broken line configuration not reasonable, no will jaw type broken machine of low power and low wear performance played out, and blindly of rely on chronology machine of chronology job, makes originally on not has powerful chronology capacity of hammer type broken machine worse, caused serious hammerhead wear, is no obtained needs of chronology grain degrees, caused has dry selected efficiency of low and serious throwing material phenomenon.

3. the Jaw Crusher (laminated broken) doesn’t play a proper function, wasting energy and does not form an effective shredder;

Jaw Crusher (laminating equipment, including cone Crusher) is the smallest power consumption and wear broken model, step by step in breaking process of fine ore, sure the Jaw Crusher (laminating equipment, including cone Crusher) breaking skills to the maximum. Currently Jaw Crusher fineness of the materials can be broken up into -30mm, and many processing companies tend to use only after the broken ore to -80mm Jaw Crusher, ore into the crushing cost of hammer Crusher of relatively much more expensive. Hammer Crusher not only do not form good crushing effect, but consumes a lot of power and wear costs.

From a cost perspective, using two-stage iron ore crushing Jaw Crusher is the 30mm levels of the lowest-cost breaking patterns. Level jaw broken a lot of enterprise process model plus a crusher, feels the investment cost of some, do not like to set, instead of taking a low investment cost of the broken Jaw Crusher model. However, this configuration and may pay a greater cost.

Therefore, we strongly appeal to all miners, understand the cost of broken equipment and principles of selecting the correct technology mode. Can generally be used a thick jaw broken fine Jaw Crusher, or thick jaw broken cone Crusher crushing production line of iron-ore processing mode is set.

4. broken process layout is not reasonable, there are a number of material handling, construction machinery consume large amounts of production costs;

Proper design can maximize the reduction of the production costs of the production line, so that each output of electricity consumption, wear wear-resistant parts, construction machinery, manual play the greatest economic benefit. Must try to reduce the crushing process of material handling and warehousing of materials should ideally be coherent after breaking into the, as far as possible using the natural terrain or belt conveyor connects the broken equipment, material handling to avoid large-scale phenomena.

Iron ore crushing and drying process design should follow the principle of least cost, in between new projects requiring process and cost accounting, the necessary equipment should not be omitted, key equipment to advanced performance. In fact, the long-term cost of investments in equipment and production lines operating cost is much smaller than, hoping to draw attention from dressing plant owners.
