Stone processing machinery and equipment



Nearly 10 years of development Chinese stone machinery and equipment has made great progress, some single performance automation level has reached the international advanced level. But in the high-end technology equipment at present Chinese is no production. From the stone enterprise automation production line for the whole, compared with foreign countries there are still gaps, some production processes still rely on manual operation, not only affects the production efficiency, but also because of the quality of staff is not high resulting in product quality unstable factors. The world stone powers of Italy stone enterprise even if most of the use of a high degree of automation of production lines, but still need personnel with certain stone a wealth of knowledge and experience, to master the process of process parameters to produce the top stone products.

At present, many foreign stone mines, especially granite mines has been fully using diamond wire saw mining blocks, and cutting processing in granite Huangliao saw, also has the promotion of bridge saws. However, in many enterprises still use the old stone China saw frame. It's a significant advantage is the cutting cost is low, but there are many shortcomings:

The assembly cost is high, about four times of diamond wire saw;
 
The operating personnel, requires at least two people. When replacing the blade more co operations;

The sawing speed slow, old frame sawing sawing speed is only 2cm/h. The new framework of the sawing speed but also 3.5-3.8 cm/h. and diamond wire saw cutting speed up to 20cm/h, may increase to 30cm/h;

Effects of diamond saw blade for stone

The surface of the plate and frame sawing of the rough, flatness is also poor, and polishing speed is low, was 100cm/min, the surface of the plate and the diamond wire sawing is smooth, polishing speed can be as high as 160 cm/min, thus reducing polishing time;

The energy consumption and material consumption are high;

The disposal of scrap mortar and the work site dust causes serious environmental pollution.

Sports shoes for purchase



Nike Womens Air Max Buying Guide
The first one:
The best in the afternoon three points to six points or so to choose shoes, because of foot slightly expansion at this time, if the selected size does not feel small, the rest of the day was also no problem. Stand try, because standing than sitting at the foot a little bigger. When trying not only to wear in front of a mirror to look at buying, must walk a few steps back and forth, carefully feeling of stability and shoe size is appropriate.
Second strokes:
When I try on the shoes self clean socks, easy to wear a pair of shoes off, avoid perspiration stains appear tried shoes in embarrassment.
The third measure:
About 2/3 people do not like the two legs, which long remember which only short, a pair of shoes to try on two legs. In accordance with the feet slightly bigger choose shoes. Can not simply according to the shoe size to choose a shoe or buy on behalf of the trustee, must personally try, because to the last, style or brand models of the different standards, the specific size of shoes will be different.
Fourth strokes:
With feet Rezhanglengsuo season will be different, so in the winter to buy summer discount shoes, you try to fit the size of the summer may be slightly smaller than.
Fifth strokes:
The ideal size is at least: ten toes can freely move in the shoes, comfortable cushions and an appropriate degree of internal space; soles of the feet and the curvature depression is a foot, ankle and toe touch shoes; QIANJIAO a certain leeway, if can between the tiptoe withstand Xietou at heel shoes and help put a finger in the distance, the size is just right; heel of the shoe on the surface to be a good paste live heel, can not slide to slide to walk; their top-down view Jiaogong shoes and the Department of the central radian is consistent, confirm the appropriateness of elastic hem.
Sixth trick:
Don't because of the end of season discount temptation or really love as an excuse to make their own feet to accommodate a pair of different sizes of shoes, size too small shoes even wear longer, support degree is also very limited, temporary instep scenery may cause corns, blisters, foot pain, leg pain, back pain and a series of disease.
Seventh strokes:
If the front of the shoes have a design, you dream of almost perfect radian, exudes the most fashionable color light, reasonable price, you can fall in love at first sight of it. Unfortunately, the material is not good, or persuade you choose Cajianerguo.
Eighth strokes:
Check the quality of shoes cortex, not in the toe and on both sides of the side leather shoes, choose shoes better touch on both sides, have a look whether the uniform thickness.
Ninth strokes:
Choose soft and flexible soles, compared to the average spread impact.
Tenth strokes:
In general, people feel comfortable with is: the higher the heel, the width kujiao; the higher the heel, the narrower the trousers.
Eleventh strokes:
Select a color of skin dark tonal than some of the shoe, can appear long legged subof.
Twelfth strokes:
If you like, we recommend choosing close to skin color lacing shoes.
Thirteenth strokes:
Choose a sports shoes science arch design, reduce the ground reaction force from the human body, the foot force balance, make the arch force in the three neutral state, reduce foot fatigue, increase the body movement function.



Hard not broken glass cup



The early years of polycarbonate (PC) material cup ruled the outdoor market in 2005 due to water, detection of bisphenol A (BPA) on human health threat, especially in children, the material cup began to "decline".

Next, the metal material Vacuum flask began to be favored, water producers also come in great numbers, more and more travelers Backpackers, carry them out of the house, even in everyday use, although the "guy" and some are not heat preservation, heat insulation is poor.

This year, like baby bottles, glass mainstream market started on the outdoor set, strong and durable Yi Qingjie silica material popular, professional water producers like CAMELbak have launched such products.

Reusable glass - not that it is a waste recycling machinery manufacturing, it looks clean, long time for water preservation, high temperature sterilization in the dishwasher, hand washing is also very convenient. But in many people the impression, glass products, there is a fatal weakness: fragile, can not help but fall, but in these new outdoor glass all do different improvement, such as the PURE brand glasses outside plating a layer of special membrane, can not see the eyes, a touch of hands, and even broken this layer is will remain intact, can't hurt.

Mixer note 8 essence



In order to reduce the occurrence of safety accidents, small make up to give all the concrete mixer concrete mixer parts driver a lesson, it is not only of the people responsible for the safety of life and property, is more of the concrete mixer truck driver of yourself and your family is responsible for. The essence of this is our professional technical staff summary notes, must be good to keep in mind, don't wait until not only to secure safety!

1, concrete delivery capacity, quality and the slump shall comply with the standards and requirements of concrete industry.

2, in the concrete in the process of transportation tank banned stops, to prevent condensation caused by concrete, stop restart will be caused by the hydraulic system, the speed reducer impact, resulting in damage to hydraulic pump and motor.

3, driving on the highway, lengthened the chute must be placed in the discharge chute bracket and hang up with hook, is not allowed to run in the main discharge chute; the main material discharging chute to rotate to a fixed position location, pull handle, locking handle will spring luffing mechanism locking, prevent the not fixed swing, possible injury accidents and the influence of other vehicle operation.

4, the working device of continuous running time should not exceed 8h.

5, discharge, such as the discovery of water evaporation, the slump is low can not meet the requirements of users, can be appropriate to a cylinder filled with water, and then to rotate the 30 after the turn speed of 10 14r/min discharge, make the concrete stir.

6, mixer in no-load operation process, the mixing drum shall not stop to avoid bumping of raceway and roller caused by local bump, abnormal damage cause the roller and raceway.

7, the water tank water often to fill, for a rainy day. Water front, the bleeder valve must be opened to release the air in the box; flushing valve is opened, flushing is completed or discontinued when the tank air. Winter Park, a water tank and a water supply system, there shall be no residual water, prevent the cracking. Note: the tank pressure only in the water, not with a pressurized water tank on the road.

8, filled with concrete is transferred, such as to reverse, must control lever so that the positive rotation stops, then the handle inversion. Strictly positive rotation process handle the inversion.

The maximum of the thermos bottle



At this point, a frequently asked question is: "if the thermos flask is so good insulation, so how to cool the spacecraft?" Spaceship accumulation of heat from its electronic equipment, fuel cell, the rocket engine and the received solar radiation, etc.. All of these heat must have a place to go, otherwise the spacecraft will overheat. However, the spacecraft is a hot water bottle floating in the world's largest (in the vacuum of outer space). Then the space ship how to deal with it extra calories?

The original heat dissipation is a very important part of the space ship design process. For example, if you look at this page, you will see Skylab (Space Experiment Station) with a gold plated coating, used to reflect the infrared radiation from the sun, there is also a large radiator to dissipate the heat. Space radiator can only use infrared radiation to dissipate heat, so it must be a radiator on earth than similar large many. In the face of the earth, convection plays a main role in the cooling process, so almost all radiator use a fan to enhance convection effect. Similarly, the medial space ship cargo port door is also provided with a radiator. Once the spacecraft into orbit, one of the things the staff the first thing to do is to open the door of the radiation.

Some research institutions for the chemical analysis of Sheng 98 days five pounds in boiling water hot water flask wall furring, heavy metals contained amount of cadmium were 0.034 mg, Pb 0.12 mg, iron 24 mg, 0.21 mg and 0.44 micrograms arsenic, mercury. The scales have the possibility to increase the concentration of heavy metals in drinking water. When using a thermos flask scale change containing other liquid, especially plum juice, beer and other acidic liquid, some heavy metal elements in the scale of the precipitates due to chemical reaction, dissolved in water or other liquid to. When people long-term small put these heavy metals intake, it may cause the human digestive, respiratory and nervous system, hematopoietic lesion and dysfunction. So, on this scale must not look down upon! Therefore suggested that people should regularly to eliminate this kind of scale.
