Two methods of construction waste

Construction waste to the city's urban environment causing serious pollution, construction waste processing is imminent. Shanghai Sanme Mining Machinery Co., Ltd. based on years of crushing sand production line equipment research and development, pioneered mobile crusher , based on the integration of units through integrated, convenient and efficient processing of construction waste crushing realization. After sorting through trash iron construction equipment to remove ferrous material contained therein, by the rough broken, broken, or even pulverized crushing equipment, processed into a certain size of regeneration Aggregates, finally applied to the stone embankment, free brick, cement admixtures and other aspects.

Sanme’s experts of construction waste say, now city building waste treatment methods based on different parts of the policy and the actual environment can be broadly divided into two types:
First, focus on
The so-called focus, focus refers to the construction waste to a specific location, unified sorting and treatment process. According to customers reflect market conditions, you can choose to focus on construction waste processing equipment, there are two, you can use either fixed sets of broken equipment, or you can choose easy transfer of mobile crusher  combination devices.
Fixed broken equipment combinations to the set of aggregates production line, including jaw crusher, impact crusher (or cone crusher), sand making machine, vibrating screen, conveyor. According to the production process for aggregate in concrete construction waste, waste bricks, stones and other processing process in order to achieve recycling. Sanme of years of research and aggregates production line equipment, quality assurance, according to the customer's actual situation, to provide the best design.
Mobile crushing plant is based on a combination of aggregate processing equipment subject process reasonably designed to achieve a variety of crushing, screening equipment, integrated portfolio, through the vehicle systems or track drive system to achieve the overall function of the mobile operations can be flexible Select the construction site, the material for timely processing, greatly reducing the cost of transportation and processing of materials, improve production efficiency. From the customer situation, the mobile crusher portfolio more in line with customer wishes, Shanghai Sanme of research and development in dozens of combinations of mobile crusher models, can maximize meet different customer needs.
Second, the dispersion treatment
For buildings littering less concentrated, or be divided into several regions handled the case, for reducing repeat purchase equipment, saving overall equipment cost considerations, the most suitable for the use of mobile crusher processing equipment.
With the development of mobile crusher technology continues to advance, at present, Shanghai Sanme has achieved the free combination of mobile crusher models of equipment, according to the actual needs of the customer, are standard, closed type, single and multistage type, and other combinations modes of mobile crusher products to choose from.
mobile crusher station provides tire type mobile crushing station and crawler mobile crusher carrying two kinds of ways of device type, you can easily turn the realization of multi-site construction, efficient and convenient.

Cone Crusher Parts Replacement

Cone crusher crushing ratio, low energy consumption, high efficiency, and a uniform particle size, suitable for crushing and fine crushing of various ores, rocks, often used as a two and three broken broken, widely use. So, various parts of the cone crusher if damaged, how to replace it? Shanghai Sanme will introduce six parts replacement method!

(1) wall replacement cone crusher, cone crusher wall is fixed on the head with a tapered conical body and zinc alloy, new installation or replacement of a new cone crusher working 6-8 hours casting wall between the two, you should check fastening, found loose to be tightened immediately.
(2) gear, due to friction and wear of the circular plate, the impact of changes in the gear gap, to ensure the normal gear must be covered with additional pads on the bottom, the thickness should be equal to the amount of wear pads circular plate.
(3) bearings and seals, bearings when installing bowl, taking care not to damage the wire rope slinger (physical support between the rope with hardwood, etc.). When assembled, the spherical bearing should be scraping the bowl to ensure the crushing cone and outer contact each other in the inner sphere should ensure that the annular gap 0.35-0.5mm. Nail bowl around the bush with Pakistan-based alloys perfusion fixed bowl bearing shelves to prevent what bowl bearing the circumferential direction of rotation.
Bowl bearing frame and body with the key (pin) fixed, if found in the work bowl bearing frame and body clearance must be treated immediately.
(4) conical bushings, air eccentric shaft sleeve and fit to be strict, in order to prevent the injection of zinc alloy rotating sleeve, zinc alloy to be filled with all the space, due to the reason of zinc alloy thermal injection may cause deformation of the sleeve, so the new set the size of the cone of inspection, found to be incorrect promptly corrected, manufacturing spare parts shall be the actual size of the inside diameter of the eccentric formulated to maintain the original tie.
(5) of the cylindrical body of the bush and the frame for the third transition fit, in order to prevent rotation of the bush, and in the upper part of the tank into the bush zinc alloy, should be replaced with new bushings when the actual size of the frame body preparation, because the crusher after a long work and will inevitably lead to changes in handling relations with. If the gap is too great cause rupture bush.
(6) of the spring, the spring is when the crusher into the not-broken when protecting the crusher is not damaged, so the crushing force of the spring pressure and adapt crusher, crusher spring during normal operation is not moving, just fall crusher iron overload lift support sleeve when the spring is compressed phenomenon occurs in the crushing chamber.

Problems in operation of cone crusher

The reason for the above is that the cone crusher problems that may arise introduction, I hope for your help.

Development History of Impact Crusher

The background of your dates back to the 1850s, The world "initial impact crusher was born in America. Before long, because of the development from the productive forces cannot meet the need of crushing the sugar cane crusher from India; therefore, individuals developed counterattack crusher on the basis of jaw crusher.

In 1924, the German initial developed the single and double rotor two varieties of impact crusher. At that time the crusher of structure is similar to the modern squirrel cage crusher. Simply because no matter from the structure or the work principle evaluation, it has the characteristics in the impact crusher.
For the reason that the material desires repeat impact, the broken might be cost-free or shine inside the process of discharging. But due to the limit of your feeding strength and impact breaker ability, the model progressively transferred into the squirrel cage crusher, applied inside the fining of medium hard.
In 1942, the German Anderson in summarized the squirrel cage crusher’s on the characteristics and working principle foundation and invented the AP series impact crusher, whose structure is comparable towards the present day impact crusher.

Advantage in the larger production effectiveness of this impact crusher and its basic in form structure, convenient to move, so, this impact crusher has created swiftly. In China, the impact crusher development began later. Only within the 1950s, our nation seriously had impact crusher. So, our crushing screening gear was mainly launched in the 50s. started early amongst the domestic impact crusher manufacturer and therefore enjoyed highly reputation in the impact crusher sector.

Routine Maintenance Of the Cone Crusher

Any equipment will be wear and tear occurs with used for a long time, cone crusher is no exception. Because of non-stop work , cone crusher wear time and the material accumulated to a certain extent , there will be some equipment wear, may result in lower yields , or the material is not an ideal situation, then you need to replace the cone crusher accessories.

Therefore , when we use the cone crusher , to regularly carry out regular inspections of equipment, accessories , case can not be used due to cone crusher wear parts , resulting in a greater degree of damage to the machine .

Sanme remind you , cone crusher parts maintenance work is very important , can cause damage to some parts of the machine further damage , and may even unusable. For example, SMS multi-cylinder hydraulic cone crusher, hydraulic system damage if one component is not replaced in time , it may cause the entire hydraulic system is not working properly, it will affect production, but will also bring the loss of interest. In addition , such type of spring cone crusher and so on , but also do inspection, maintenance , especially after a period of time to look at the spring there is no need to replace the gasket .

Cone crusher crushing wall using new composite materials forged a cost-effective , super wear-resistant, wide applications and so on. After a new installation or a new replacement cone crusher wall work six to eight hours , you should check their retention , should be immediately found loose fastening , cone crusher to avoid unnecessary damage .

Cone crusher machine using the machine lies maintenance, so the machine will work for you longer , but your interest is to get the corresponding reward.

best options for processing minerals

There are significant opportunities for the mining and processing of banded magnetite deposits on the African continent. A natural iron-ore deposit is a single deposit with little waste rock mixed into it. With massive iron-ore deposits, the head grade can be 60% to 70%, which means fewer impurities need to be removed before processing the ore into pig iron. The most massive ore bodies consist of hematite, which are the principal and the most stable of the iron oxides. The first step in the comminuting process and liberating a mineral from the ore body begins at the mining stage, with drilling or blasting and excavation used to generate materials that are easily transportable.

Crushers are then used to produce coarse size reduction and grinding mills are used to produce finer particles. As for the crushing process, Sanme crusher is a great option!

The ore mined from massive ore bodies is suitable for use in blast furnaces, they simply need to be crushed into pieces of between 10 mm and 25 mm, and then transported as lumpy ore to iron and steel plants worldwide. The ore is first crushed to size and then passed through a dense media separation process. The dense medium, with a specific gravity of around 3.6 t/m3, is created by mixing water with finely ground ferrosilicon powder. Anything with a specific gravity of less than 3.6 t/m3, for example silica-based rock, which has a density of 2.8 t/m3, will float, while the lumps of hematite iron-ore with a density of around 5.0 t/m3 will sink. What you see coming out of this process are big rocks floating in what looks like black water.

There are several kinds of comminution. In-pit comminution includes blasting, rock breaking and continuous mining; scrubbing, which is used as a polishing agent and not primarily for size reduction; crushing, which includes gyrators, jaw crushers, impactors and mineral screening; and grinding mills, which include the most commonly used semiautogenous grinding (SAG) mills, autogenously grinding (AG) mills, ball mills and rod mills..
