Economic Benefit of Investment in Pebble Sand Maker

The return of investment is the Construction Waste Crusher issues concerned by vast number of investors and business owners. After all, the great deal cost to implement the project is for better return. For this issue, Machinery makes an analysis on some issues in the investment of sand maker or sand making machine. How is the use condition of river and pebble sand maker? China carries a wealth of river gravel which is qualified raw materials for artificial sand making. Pebble is generally rolled through long-term weathering of other rocks, losing angular shape to be the egg-shaped, so it’s also known as river gravel. Currently, the stone resource of more than half of the construction of buildings, roads, bridges and culverts, water conservancy and hydropower are from highly processed pebble.

Sand stone is a hot investment Lead Zinc Ore Crushing Machine projects for investors. For environmental protection, the Government has banned River sand mining, while encouraged the building of quarries, and made sand by sand making machine. River gravel sand production line has short payback period, usually 3 months can recoup their investment, so the demand for large, medium and small sand stone plant equipment is increasing. River gravel production processes is similar with other mining and quarrying machinery. River gravel production line mainly composed of the vibration feeders, jaw crusher, sand making machine, vibrating screen and belt conveyor, sand washer, sand collector, precipitator equipment and other machinery, which can combine various types of equipment depending on the process requirements.

If you have a good understand on river sand investment, you must know that river sand and stone prices accounted for a large proportion, and production and distribution of the finished product of river sand is also very important. River sand gradation is determined by the performance, material hardness, moisture content and other decisions of the equipment. According to the market demand, our constantly improves our production technology to produce sand making machine for coarse, medium, fine and super fine sand making, for the diversified needs of the market. Machinery believes that election a good project is tantamount to selecting the wealth, and selecting the right equipment can speed up the success and close to the wealth.

Two types of grinding machines of our company

In materials processing a grinder is a Ultrafine Mill machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.

Ball mill

A typical type of fine grinder is the Artificial Sand Making Plant Design ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world’s power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.

Operation of a ball mill. The power predictions for ball mills typically use the following form of the Bond equation: Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. But note that the term ‘rod mill’ is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.

The new demand of construction waste crushing

When the sustainable Sand Making Plant Design development is becoming more and more important, piling up and landfills have gone against with life concept of creating low carbon, environmental protection and energy conservation and emission reduction. Hence, it is urgent to dispose of the trash during development. So it comes to us how to deal with it. In recent years, along with the crunchy building, collapse road and demolishing and building frequently, a great number of construction trash is inevitable to be generated. Therefore, the garbage is produced at the speed of hundreds of millions of tons every year. Nevertheless, it can be seen everywhere that these building rubbish is buried simply and piled up arbitrarily that make the garbage siege approach to us quickly.

As a matter of fact, the Mobile Crusher Machine Sale construction trash is chiefly composed of solid wastes, which can be reused through crushing and screening. In other words, the construction rubbish can be turned into building materials via professional disposition, such as brick, stone and concrete. They can replace the sand to apply in masonry mortar and front mortar after being crushed; after being crushed, the waste concrete block can be blended with the standard sand to plaster the wall and ground, in roof mortar leveling and masonry mortar, to make floor tile etc. that have greatly save the energy as well as the resources, achieving clean production and self-closing recycle economical industry chain. This also can protect the environment of the human beings to realize the sustainable development—a virtuous road to realize economic benefit and social benefit thus creating a maximal wealth.

According to the engineers in our company, job reluctance never happened in this series of crushers during refuse processing. Its advantages can be displayed fully in the process of work. Moreover, the disposed construction trash is counted as a real hero no matter in building aggregate or paving the road.

Three modern kilns for producting quicklime

The theoretical heat (the standard enthalpy) of Artificial Sand Making Plant Design reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns, similar in construction to blast furnaces. These are counter-current shaft kilns. Modern variants include regenerative and annular kilns. Output is usually in the range 100-500 tonnes per day.

Counter-current shaft kilns

The fuel is injected part-way up the shaft, producing Stone Crushing Equipment Sale maximum temperature at this point. The fresh feed fed in at the top is first dried then heated to 800C, where de-carbonation begins, and proceeds progressively faster as the temperature rises. Below the burner, the hot lime transfers heat to, and is cooled by, the combustion air. A mechanical grate withdraws the lime at the bottom. A fan draws the gases through the kiln, and the level in the kiln is kept constant by adding feed through an airlock. As with batch kilns, only large, graded stone can be used, in order to ensure uniform gas-flows through the charge. The degree of burning can be adjusted by changing the rate of withdrawal of lime. Heat consumption as low as 4 MJ/kg is possible, but 4,5 to 5 MJ/kg is more typical. Due to temperature peak at the burners up to 1200cin a shaft kiln conditions are ideal to produce medium and hard burned lime.

operation of regenerative shaft kilns

These typically consist of a pair of shafts, operated alternately. Fitst ,when shaft A is the primary and B the secondary shaft, the combustion air is added from the top of shaft A, while fuel somewhat below via burner lances. The flame is top-buttom. The hot gases pass downward, cross to shaft B via the so called channel and pass upward to exhaust of shaft B. At same time in both shafts cooling air is added from the buttom to cool the lime and to make exhaust of gases via the buttom of the kiln impossible via maintaining always a positive pressure. The combustion air and cooling air leave the kiln jointly via exhaust on top of shaft B, preheating the stone. The direction of flow is reversed periodically (typically 5-10 times per hour) shaft A and B changing the role of primary and secondary shaft. The kiln has three zones: preheating zone on the top, butning zone in the middle, and cooling zone close to the buttom. The cycling produces a long burning zone of constant, relatively low temperature (around 950C) that is ideal for the production of high quality soft burned reactive lime. With exhaust gas temperatures as low as 120c and lime temperature at kiln outlet in 80c range the heat loss of the regenerative kiln is minimal , fuel consumption is as low as 3,6 MJ/kg. Due to these features the regenerative kilns are today mainstream technology under conditions of substantial fuel costs. Regenerative kilns are built with 150 to 800 t/day output, 300 to 450 being typical.

Raymond mill plays a crucial role in milling production line

Raymond mill plays a crucial role in this set of production lines.

In the entire production line, Raymond mill could make the material into a finished part. After being crushed to the desired particle size, the materials are sent to the hoist storage hopper, and evenly fed into machine host byvibrating feeder; the shovel blade shovels the materials and sends them between the grinding roller and grinding ring, and the materials, in the role of the grinding pressure, are crushed into powder. Then the powders are blown up by the blower to the analysis machine. If the powders meet the fineness, they can go through the analyzer and be collected by the micro powder cyclone separator; otherwise, the powders have to return to the grinding chamber to continue grinding. Raymond mill to production line is what the engine to the car, and the heart to the human body; so careful consideration when selecting mill is critical.
