DS(customers mine name in short) copper concentrator has encountered problems such as easy plugging of screen surface and heavy screen funnel, low screening efficiency of vibrating screen, frequent maintenance of some equipment, coarse particle size of crushed products, etc. The technical transformation is needed to influence the smooth operation of the production.

In the concentrator, the hardness of the ore is 8 ~ 10, the grinding power index is 14 ~ 15 kWh/t, the moisture content is 3%, and the loose density is 1. 69t/m 3, Density 2. 7tm3. The rock crushing system is mainly equipped with a vibrating feeder, 16 sets of conveyor belts, and 6 sets of heavy-duty double-deck vibrating screens (pre-screening, heavy screening), 17 single-layer vibrating screens (check and screen, single screen), 4 medium crushing Simons cone crushers and 8 fine crushing Simons cone crushers.

The coarse crushing equipment is three 54 mm*74 mm cycle crushers. The coarse ore is transported to coarse ore heap by three Iron plate feeders. The stone crushing section is responsible for the medium and fine crushing operations of the ore. This process strengthens the pre-screening before the medium crushing and eliminates the adverse effects of the sticky wet powder ore on the ore crushing operations.

A new cone crusher is used to reduce the particle size of the crushed product, and the metal crushing efficiency is improved by automatically controlling the power of the crusher and filling the ore as much as possible, to ensure the particle size P80 of broken mineral products meet the requirements of grinding operation, then improve the grinding efficiency.

More water flow, easy plugging of screen surface and heavy screen hopper, low efficiency of vibrating sieving, serious aging of Simmons cone, insufficient production capacity, frequent overhauling, affecting production, high system operation rate and coarse grain size of the broken product.

The technical transformation of ore crushing technology includes the adjustment and optimization of technical parameters of existing crushing equipment, the improvement of screening equipment, the improvement of screening efficiency and the reduction of final crushing product granularity. During the transformation of the crushing system, the maximum and minimum feed and discharge parameters of each crushing equipment should be considered, and the transport capacity of the conveyor belt should be considered comprehensively to ensure the normal operation of crushing system.

Installation of connecting flume under the coarse ore heap and at the outlet of the vibrating bucket will lead the accumulated water out, and will lead the water from the high building to the sewage pipe, so that the flow water is greatly reduced, thus improving the screening efficiency and reducing the equipment failure rate.

3.2.1 Add Weight screen Adding the original 2 heavy sieves to 3 sieves, reducing the working load of medium crushing, appropriately enlarging the size of the sieve to 12 am *25 mm, and increasing the product yield efficiency 8% to about 13%; gradually replaced the original single screen with the advanced two-stage screen to improve the stability of the inspection screening operation and to provide the guarantee for balanced stable and efficient organization of production. 3.2.2 Screen surface upgrade Chang the rubber screen mesh into the rubber steel wire screen mesh, to extend the service life of the screen Mesh, the drop of large pieces of ore will be reduced, and the opening form of the screen Mesh be changed from the original straight tube type to the trumpet type, thus reducing the probability of ore blocking the Screen Mesh. The opening ratio of the screen was increased from 37% to 42%, thus increasing the effective use area of the vibrating screen and the screening efficiency from 71% to 75%. 3.2.3 Screen frame support spring upgrade The original screen frame supporting spring is a rubber spring with an amplitude of 2.0 am, which is easy to be sheared and compressed, poor in oil resistance and light resistance, and easy to be aged. After replacing the high-strength and large-diameter steel spring, the amplitude is increased to 6.5 mm, the service life is prolonged, the bearing capacity is strengthened, the screening speed is accelerated, and the screening efficiency is improved.

Before 2000 years ago, there were 4 middle-crushing Simons cone crushers, # ~ 4#, and 8 fine-crushing Simons cone crushers, 1# ~ 8#. From 2000 to 2004, four high-efficiency H8000 mm hydraulic cone crushers were introduced to replace 1 #, 2 # medium-crushing Simons cone crushers and 1#, 2 # fine-crushing Simons Cone Crushers. In 2009,2 Metso MP800 MM cone crushers were introduced to replace 1# and 2# Fine Simmons cone crushers to solve the problem of insufficient fine crushing capacity In 2012, 2 METSO MP800 mm cone crushers were introduced to replace 3 # and 4 # Medium Simons cone crushers, and in 2016,2 Metso MP800 MM cone crushers were introduced to replace 1 # and 2 # medium crushing H8000 hydraulic cone crushers solve the problem of hydraulic cone crusher can not automatically adjust the ore discharge size.

In 2016, four Metso MP800 mm cone crushers were adopted, although the capacity and efficiency of the crushers were improved, the final crushing product particle size P80 still did not reduce. In order to solve this problem, a new type of XT750 liner board is developed, which increases the width of parallel band of liner board from 25 mm to 30 MM, prolongs the time of ore remaining in parallel band, increases the times of ore being broken and impacted in crushing zone, and increases the fine particle content in ore discharge Reducing the particle size of the final product of crushing. At the same time, the thickness of lining board is increased by 25%, and the manganese content of the material is increased from 14% to 16%, which can solve the problems of the lining board such as serious wear and tear in the later period, easy to plug up the bucket, increased energy consumption, uneven crushing and lower crushing efficiency, and prolong the service life of the lining board.

The feeding hopper can not feeding ore uniformly, the ore is scattered in the cone crushing chamber, the ore cannot be crowded, the crushing efficiency is low, and the size of the discharging ore is coarse. By adding an 80 mm*1000 mm central funnel to the ore feeder and setting a 900 mm concave ore separator above the moving cone, the ore feeder is lowered through the central funnel and dropped vertically to the Ore Feeder Evenly distributed in the cone crushing cavity, crushing cavity feeding uniform, smooth running current, reduce loop jump, to achieve full ore.

(1) Increase crushing capacity. The cone crusher has been reformed several times, and the capacity of the ore crushing system has been improved remarkably. The problem of the insufficient capacity of the crushing system has been solved. The annual capacity of the crushing system has increased from 24.237 million tons in 2013 to 24.499 million tons in 2016. (2) Through the technical transformation of the drainage device, the pre-screening and screening vibrating screen, the type of the medium-fine cone crusher is changed, and the production management is strengthened, so the production capacity of the crushing process is improved to a certain extent The potential of the rock ore crushing equipment is brought into full play, the running rate of the equipment is reduced, the equipment is convenient for maintenance, and the particle size of the final crushing product is reduced to P808.5 mm, thus creating favorable conditions for the efficient production of the grinding operation The utility model has the advantages of energy saving, consumption reduction and labor intensity reduction.

rock crushers

rock crushers

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.

iron ore crusher price, crushing machine for iron ore beneficiation

iron ore crusher price, crushing machine for iron ore beneficiation

Iron ore beneficiation begins with the milling of extracted ore in preparation for further operations to recoveriron values. Milling operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high.

Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches. Oversize material is passed through additional secondary crushers and classifiers to achieve the desired particlesize.

In iron ore beneficiation operation, the raw iron ore materials will be first reduced to small particle size. It may require crushing the material tomaximize the production of minus 2mm. According to SBMs experience in crushing technology, we recommended the installation of acone crusher to reduce the minus 100mm pebblesand a VSI crusher machine to fine crush the cone crusherproduct.

The iron ore crushers with low price are also used in the industrial minerals, mining, recycling and general quarrying industries. A widerange of materials are processed through SBM iron crushers worldwide. SBM experts can customize crushing solution in iron ore beneficiation according to your requirements. Here are some popular iron ore crusher machine types. Please contact us for more information.

According to different final products applications, varioustypes of crusher equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing. Iron ore crusher prices are different according to crusher types and production capacities.

The VSI crusher for iron ore beneficiation uses a unique rock-on-rockcrushing action whereby the feed materialgrinds and impacts against itself, minimizingwear costs and maintenance down-time. Thisis especially important in applications such asiron ore processing where the feed material istypically hard and abrasive and wear costs arepotentially very high.

Jaw Crusher Jaw crusher is available with stationary, mobile and portable applications. The jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials. This is achieved through several unique features such as higher crushing speed, optimized kinematics, a longer stroke and easy adjustment.
