Sandvik Commando

Modern sand crusher experience trails and errors This new type impact crusher is widely used all over the world in recent 20 years. It has been proved that this series of crushers can effectively increase productivity and final product quality. And they can also greatly reduces the investment costs and operation costs. Incomparable excellent performance is shown in the secondary crushing, tertiary crushing and material recovery. Impact crusher is widely used in stone crushing plant and sand making production line for construction building materials.

It can crush big stones or rocks such as quartz, basalt, shaly, kaolin, limestone, marble etc into small size for building aggregates or manufactured sand. With economic development, the state strong support infrastructure such as railways, highways, bridges, hydroelectric project construction, the construction of the project can not be separated from the sand and gravel aggregate, general infrastructure projects, if with less material can be directly from the sand quarry procurement. The vast majority of large-scale projects such as railways, highways, bridges, hydropower project, located in the mountains or deep valleys, construction sites, narrow, tight construction period, large amount of concrete works, the high strength of concrete construction, strict requirements on the quality of the sand aggregate mechanism. Excellent mechanism sand equipment with modern levels of technology and dynamic economic indicators and mechanisms of sand production line design to ensure that the project will require grading mechanism sand aggregate, in the regulation of the whole project during the construction period dynamic balance of production and supply is the fundamental purpose of the mechanism of Sharjah plant design. The trials also established that a cheaper and more effective drilling method had to be adopted.

It was decided to develop a horizontal method to drill through the centre of each concrete layer, which allowed the heavy rebar at the top and bottom of each layer to be avoided. In the end, Safedem decided to use Sandvik Commando rock drill machine that was adapted to allow it to horizontal drill holes to a depth of up to 4 m (13 ft). This created another challenge how to load the holes with explosives. As a result, the charges were pre-assembled in a heavy duty 38 mm (15 in) diameter, 1 m (3.3 ft) long polythene tube. Each charge consiste perunit and amoblast with a charge per hole weight of 1.2 kg (2.6 lb). However Safedem developed an in series 300 millisecond delay detonator connection between up to 10 20 hole sections, allowing up to 250 kg (550 lb) of weight to be detonated over a 3 second charge time period. A series of mill10 ball blast sections produces upwards of 1,500 m3 (53,000 ft3) of concrete debris.

Sand Production Line

The role of sand maker in sand production line Carborundum can use as combing hard alloy cutter in machining. Processed silicon carbide plate can be used as Jose board in Pottery firing. Finish machining micro powder can use as painting in the high-tech electronic component and far infrared radiation materials, high purity micro powder can use as the coating of vessels in Aerospace defense industry, it has been widely used in all economic field at home and abroad. Hongxing sand production with a full set of equipment has a high degree of automation. All links of the the whole production line are finished by production except the boot, shutdown and routine maintenance of the equipment by manual operation. The sand production line meets various needs of national high-speed pipes because its high production efficiency and handling intensity, low power consumption and noise, which makes finished stones in uniform particle size and shape of good grain.In the operation of the equipment, there will be a variety of simple or complex faults.

How to deal with problems? Remember not to feed much in the operation of the sand maker. The crushing cavity will be blocked If the sand maker is fed too much. When the crushing cavity is blocked, you should immediately stop feeding and not start again the feeder until the material in the cavity is completely crushed. It is noteworthy that the machine cannot stoped in this process. In order to maximize the effectiveness of the sand maker, we should make an tour inspection in the operation of the machine, observe the working conditions of the various components and pay much attention to the temperature of the bearings. For large plain bearings, high temperature will prone to cause bush-burning accidents.

Another thing you should note is that reducing the temperature of the bearings immediately when the temperature is too high but you must not immediately stop the operation of the machine. Without endurable quality, the development of any enterprises will become fantasy. An enterprise or an industry will always come cross the cold market situation, under this situation; enterprises should enhance Internal Strength, and depend on their first class products and first class brand to open and stabilize market. As for the develop prospect ofsand washing equipment, we should see farther. Quality is the basic of enterprise, under the bad background, the enterprise should pay more attention on the quality. Hongxing brand sand maker does well in this aspect, except for the guaranteed quality, the company pays more attention on the new technology development and application of sand washer.

Take Scientific Method

The limestone crushing system in domestic cement plant often uses the two-stage crushing or one-stage crushing. The one-stage crushing system includes a dual-rotor impact breaker or a single-stage hammer crusher. With the emergence of the large-sized vertical shaft hammer crusher with excellent performance, many new and expanded enterprises chose the vertical impact breaker with good tightness, large crushing ratio and small particle size to improve the yield of the raw materials of the mill. In recent years, Henan Hongxing Mining Machinery has developed a new crushing equipment, namely cone crusher. The extrusion crushing is produced when the liner closes to the backplate. This kind of crusher has high crushing ratio. It has many advantages.

It has been widely used in many projects. In addition, many manufactures try to transform the crusher so that it can better adapt the production. In recent years, the power is sent to the vibrating exciter. The Inertial eccentric force produced by the vibrating exciter so that the crushing cone can be used as the secondary crushing equipment of the limestone. The materials enter the backplate and the crushing chamber with the frequent vibration and rotation. Learned from a cement plant in Hebei Province, at present, the concrete mixing plant has an immeasurable development prospect, so this plant is ready to take the cement concrete mixing plant as a new sales channel. We know that the cement and sand is very important for the concrete mixing plant. Therefore, in order to obtain greater profits, many cement plants began to cooperate in cement and sand.

They crush the abandoned limestone and basalt crusher sand maker or by, and then sell the final products with the cement, which will get more benefits.As the professional manufacturer of complete sets of mining machinery, such as cement production line, Henan Hongxing is always doing the best in products and service. It is reported that the river pebble, limestone and granite can be used as the main raw material of the gravel cogeneration. Especially for the river pebble, it is widely distributed in various regions of our country. Therefore, there are a lot of river pebbles production lines in our country. In April of this year, Hongxing Company provides a river pebble crushing system and a production line for a small gravel gravel enterprise in Urumqi, Xinjiang Province. This production line is mainly composed of the fine Jaw Crusher, Symons Cone Crusher, high efficiency Sand Making Machine, Sand Washing Machine, Vibrating Screen, and all the equipments are working in the centralized control.
