Technological innovation is the key to the development of mining industry. As far as sand making industry is concerned, technological innovation of sand making machine and its related supporting equipment can not only improve the productivity of the whole sand making production line, but also increase the income of users. Therefore, technological innovation is the key to promote the development of sand making machine.

Science and Technology Make Sand Making Machine Innovation

1. The crushing mode of sand making machine is diversified. Traditional sand-making machines mostly adopt single stone-breaking principle, while sand-making machines incorporating more new technologies adopt two kinds of breaking methods, namely stone-breaking and stone-breaking iron-breaking principle, which can meet the production needs of different users.

2. The feeding mode of sand machine can be selected. In the past sand production line, the way of ore material feeding is relatively single. After technological innovation, the sand machine can adjust the angle according to the installation position of the feeding belt, so that the material is evenly scattered in the feeding chamber of the equipment. It can be divided into waterfall feeding mode and the whole-center feeding mode.

With the improvement of technology level of sand making machine, the automation of sand making machine with high technology content is higher, and the sand making process is more convenient and fast. For the common living environment, the unique sealing device of sand making machine can effectively reduce environmental pollution and conform to the trend of green production.

Raymond mill is a kind of equipment widely used in mine development and grinding. Raymond Mill plays an important role in practical application. Raymond mill is mainly composed of main engine, analyzer, fan, finished cyclone separator, fine powder cyclone separator and air duct. Among them, Raymond grinding machine is composed of frame, intake volute, shovel cutter, grinding roll, grinding ring and cover.

Raymond mill is a new type of mill developed to process powder instead of ball mill. All kinds of technical indicators have reached the advanced level in China and are highly praised by users in various industries. Raymond mill adopts the advanced structure of similar products abroad and is updated and improved on the basis of large Raymond mill. Raymond mill is a new type of energy-saving large, medium and small-sized Raymond mill developed independently. It is guided by modern design means and advanced grinding theory. The grinding roll is designed at both ends of the center line of the plum blossom rack, so that the grinding roll device is in a natural equilibrium state. The main machine works fairly smoothly and the vibration is very small.

The main reason why the output of the new energy-saving Raymond mill is higher than that of the ordinary three-roll Raymond mill is that the space occupied by the grinding roll in the working chamber of the main machine of Raymond mill is small and the working space reserved is larger, and the high-pressure wind energy of the blower can enter more working area, so that the grinded fine powder has more opportunities to be quickly taken out of the main machine and entered the cyclone collector, thus avoiding repeated and invalid grinding of the superfine powder. That's it. The new type of energy-saving Raymond mill has only two rollers, and its working load is lower. It saves 25% electricity than the ordinary three-roll Raymond mill with the same specifications, and its output is 20% higher than that of the three-roll Raymond mill with the same specifications.

The new portable crusher plant is an environmentally friendly and high performance mobile crushing station. It can be divided into crawler type portable crusher plant and tyre type portable crusher plant according to two driving modes. The body of portable crusher plant is integrated and has strong maneuverability. The traditional piling, capital construction and complex installation procedures are not required. It can be directly opened to the stone yard for operation without site restriction and large production capacity. The work here can be completed. Move to the other side at any time, and your efficiency is beyond your imagination.

Regarding the efficiency of Raymond Mill, both the manufacturer and the customer are constantly exploring. The manufacturer hopes to produce more output equipment. The customer hopes to make the equipment play a better productivity through operation. First, regardless of the design process of the manufacturer, the machine will be affected a lot in the use stage. Here is to introduce the factors affecting it.

1. Material hardness, generally speaking, the harder the material added to Raymond mill is, the longer it takes to produce finished products of the same particle size, which means that the grinding difficulty of the equipment will increase, at this time its efficiency will decrease, and this phenomenon will also lead to the increase of equipment wear.

2. If the materials added to Raymond mill contain more fine powder, they will easily adhere to the inside of the equipment and affect the conveying process, which is also an aspect of the efficiency. The solution is to screen the materials with more fine powder in advance.

3. Material humidity, if the material added to Raymond mill contains a large amount of moisture, it will adhere to the inside of the equipment, which will cause blockage in the feeding process, and then affect the production efficiency, so it is also important for the treatment and selection of humidity.

4. In production, the better the wear resistance of Raymond grinding fittings, the better their performance at work. In this way, the greater their ability at work, the better the grinding of materials and the better efficiency can be achieved. The realization of this need to ensure that the selected equipment has good wear resistance at the time of selection.

5. Reasonable maintenance and maintenance of Raymond mill can effectively reduce the wear and tear of parts and prolong their service life, which is also an important scheme to help equipment get better working efficiency.

This article mainly introduces the analysis of Raymond mill efficiency, because the efficiency is related to the income of production, so customers pay more attention to Raymond mill efficiency and its influencing factors. Here is to introduce the influencing factors of Raymond mill efficiency, mainly in five aspects. The analysis above is more detailed.

Sand making machine is an irreplaceable equipment in mining and construction industries. Its use expands the scope of ore use and protects the exploitation of natural sand. The machine-made sand produced by sand making machine has become a better substitute for natural sand. It has many superior properties than natural sand, such as: larger surface area ratio than natural sand; higher strength of concrete prepared with machine-made sand; machine-made sand particle size can be selected according to demand, and the particle size is uniform. In addition, manufactured sand is also conducive to the comprehensive utilization of mineral resources, which not only solves environmental problems but also improves the utilization rate of natural resources.

Sand making machine gradually opens up the market with the following advantages, and the investment prospects become broad.

1. Large throughput

The design of deep cavity rotor used in sand making machine has a large throughput, which can ensure the output.

2. Easy maintenance

Hydraulic capping device used in sand making machine is easy to maintain and repair.

3. High crushing rate

The stone breaking chamber used in sand making machine makes the breaking efficiency higher.

4. Strong controllability

The thin oil lubrication used in sand making machine can provide a larger speed range.

5. Complementarity of Double Oil Pumps

Sand making machine uses double oil pumps to supply oil, and stops automatically when there is no oil flow and no oil pressure.

100t/h environmentally friendly high-pressure Raymond mill is an equipment with a capacity of 100 tons per hour for grinding materials. It is the key equipment for crushing materials after they are crushed. Raymond mill is suitable for more than 100 kinds of materials, such as quartz sand, fluorite ore, coal slime, etc. It can adapt to many kinds of materials, and can adapt to wet, dry and mixed grinding of various mines and rocks. At present, it is widely used in transportation. In industrial construction such as mines, the use effect is good and the economic benefit is high, which has been approved by users.

How does the 100t/h Raymond mill work?

Material is evenly fed into the mill silo by feeding device. The mill silo is equipped with steel balls of different specifications. When the cylinder rotates under centrifugal force, the steel ball is brought to a certain height and falls down, which has a heavy impact and grinding effect on the material. After the material is roughly grinded in one silo, it enters the second silo through a single-layer partition board. The silo is inlaid with a flat lining board and steel balls, which further grinds the material and grinds it after grinding. The powder is discharged and the grinding operation is completed.

Why is the output of 100 t/h Raymond mill high?

1. Advanced technology, high wear resistance: environmental protection high-pressure Raymond mill uses quenching technology, so that liner can withstand tremendous impact in production, reduce liner deformation and wear.

2. Reliable operation and long service life: The environment-friendly high-pressure Raymond mill uses modified gears, which improves the power performance and lubrication state of gear transmission, improves the reliability of operation of high-pressure Raymond mill, and enlarges the rolling bearing part of the environment-friendly high-pressure Raymond mill, enlarges the distance between the rolling bearing and the screw drum in and out, and prolongs the service life of the equipment.

3. Energy-saving and environmental protection, low energy consumption: environmental protection high-pressure Raymond mill uses thin oil lubrication instead of grease lubrication, to prevent poor lubrication due to oil shortage, energy-saving and environmental protection, greatly reducing the loss rate of components, low energy consumption.

Whether Raymond mill can achieve ideal grinding effect depends on the grinding medium and lining plate. Lining board is a very important part of Raymond mill, which directly affects the grinding effect. So how to choose lining board correctly and how to choose suitable lining board is a very important problem. When it comes to the choice of liner, the key is to see the thickness of liner. Does it affect the grinding effect of equipment?

We know that the thicker the liner of the Raymond mill, the better the wear resistance of the Raymond mill. Does that mean that the thicker the liner, the better the wear resistance, the thicker the liner of the Raymond mill will increase its wear resistance properly, but the life of the liner is closely related to the material of the liner, so the good choice of wear resistant material with high hardness is the good policy to improve the life of the liner?

Our company's mineral processing Raymond mill uses high chromium steel balls, bearing steel forging, lining plate using high manganese steel. At the same time, Raymond mill of our company adopts modified high manganese steel, ultra-high manganese steel and ultra-high chromium cast iron. By controlling solidification mode and optimizing heat treatment process, it can make lining plate have high hardness, good toughness, impact resistance and wear resistance. However, the thicker the lining plate is, the better, the thicker the lining plate is. Otherwise, the thickness of the lining plate of the Raymond mill will cause the weight of the whole Raymond mill to increase and the power of the motor to increase. Therefore, the lining plate of Raymond mill should be increased appropriately and the wear resistance is good.
