Two theories are currently being investigated by local police over last night’s Dortmund bus bombing which injured Marc Bartra.

Several German media outlets have reported that a letter was found at the scene with the words: “in the name of Allah, the merciful, the merciful,” written on it, which has provoked these organisations to speculate about potential Islamic extremism links to the incident.

The Süddeutsche Zeitung however indicates that the authorities are remaining very cautious: “It is possible that those who committed the act wanted to put the blame on someone else.”

The German police’s second theory involves the idea that the act was committed by a German anti-fascist group. A claim was posted on a blog last night, Die Welt reveals, reading as follows: “Today we attacked the BVB bus with explosives.”

The blog post has since been removed. The author of the post explained the reasons for the attack: that it was a show of force against the club because it is not doing enough to fight fascism in the club nor the detestable attitude within the stadium, allegedly the reasons for this anti-fascist group committing this act, if they did so at all.

The letter found at the crime scene has yet to be verified.

Grinding Media Feature Common Equipment Common Equipment Natural grinding ball Low density grinding medium, low price, but large wear, low grinding efficiency.  —– It is easy to increase the free quartz in the porcelain, thus reducing the thermal properties and strength of the porcelain body, especially for magnesium and aluminum reinforced porcelain. SiO2 Grinding Media  Small density, high abrasion, low grinding efficiency, brittle.  Mixing ball mill, sandmill, planetary ball mill. Only for experiments and some special industries, the amount is very small.In addition to the grinding of quartz powder and some special powder grinding other ceramic powder grinding are not using quartz glass ball. Al2O3 Grinding Media  With wear resistance, corrosion resistance, high temperature resistance, impact resistance and other excellent performance.  Small and medium high speed horizontal, narrow slot type vertical mixing mill and other grinding machines. Widely used in white cement, mineral processing, ceramics, electronic materials, magnetic materials, as well as coatings, paint and other industries of raw materials powder grinding processing. ZrSiO4 Grinding Media  Compared with ZrO2 medium, it has high wear and low strength, so it lacks good market promotion prospects. Sander.  It is mainly used for ultrafine grinding of ZrSiO4 raw materials. It is the preferred grinding medium for ultrafine grinding of ZrSiO4, with a certain cost performance. ZrO2 Grinding Media High density, large impact force, high grinding efficiency;The surface is smooth and hard, the wear is small, so as to avoid the product pollution;Can reduce the required grinding time, suitable for wet grinding. Suitable for all kinds of ball milling, grinding and polishing equipment. Used for "zero pollution" and high viscosity, high hardness material ultra-fine grinding and dispersion, such as: electronic ceramics, magnetic materials, zirconia, silica, zirconium silicate, titanium dioxide, medicine and food, pigment, dye, ink, special chemical industry. Silicon carbide grinding media  It has the advantages of high strength, high hardness, oxidation resistance and corrosion resistance at high temperature. Sand mill, strong pressure micro powder mill, silicon carbide mill. Can be used for all kinds of powder material ultrafine grinding, such as silicon carbide ultrafine powder, and all kinds of precision bearings. Silicon nitride grinding media  High oxidation resistance;The hardness, compressive strength and elastic modulus of zirconia ceramics are much higher than those of zirconia ceramics.  Sand mill, vibration mill, planetary mill agitation mill. It is an indispensable grinding medium in the production of silicon nitride powder and is widely used.At the same time, more suitable for sand mill, vibration mill and other high-energy ball mill equipment.

 

The selection of grinding media is a very important problem in the process of ultrafine grinding, different grinding media have different chemical elements.In the actual production process of grinding, we should first pay attention to whether the chemical composition of the grinding medium will react with the grinding material, so as not to cause material pollution.For example, in the field of grinding pesticides, medicine and biochemistry, heavy metals are considered as elements, and medium containing heavy metals cannot be selected.Secondly, in the grinding of superhard materials such as: silicon nitride, silicon carbide, etc., as far as possible to consider the use of the same medium grinding ball.

Therefore, according to some physical properties (hardness, density, wear resistance) determined by the chemical composition of the grinding medium and the pollution of its own wear to the slurry, the selection of suitable grinding medium is helpful to improve the crushing efficiency, product quality and reduce the comprehensive cost in the process of ultra-fine grinding.

To our valued customers:

Happy New Year to all as we bring on 2023! Each year as the calendar turns, we like to utilize this season as a time of reflection and communication with our customer base. This is a moment for us to offer commentary on the events and accomplishments of the preceding year and to say “Thank You” for the trust and confidence that you, our customers, place in us each and every day.

A look back:

In looking back over the events of the previous year, 2022 will be remembered as a year of “inflation gone wild”. Although many inflationary characteristics were already materializing in 2021, I do not think anyone, at the onset of 2022, expected the continued inflationary burdens that we have seen. This pressure is being felt as a country as well as around the entire world by companies, municipalities, and individual families trying to navigate this new and challenging landscape. Not since the early eighties, have we seen inflationary complications of this magnitude which represent some of the worst of our lifetime. As always, Astro will make logical business decisions and will capitalize on opportunities as they manifest themselves throughout the year. Just like the great recession of 2008, many companies pulled back and let opportunities pass them by while Astro intensified its efforts, navigated the challenges of that time, and took market share in the process. We will always approach challenge and uncertainty aggressively and with sound and practical strategies. Having said that, we are happy to report that our continuous improvement initiatives over the last year, including our ERP implementation, and All-Fab acquisition are going well and have been contributing nicely to our overall success throughout 2022.

A look ahead: 

As we look ahead to 2023, we are opting for calculated growth once again as we look to increase our capital expenditure budget specifically for the purpose of adding a second Gantry Mill to our arsenal of large machine tools. As we continue to gain momentum in the large machining marketplace, we are installing a Parpas Diamond Linear 30, 5-axis machining center to provide added capacity. With travels of 118” x 102” x 47” respectively in the X, Y, & Z axis, this will be a perfect complement to our existing Gantry Mill, Bridge Mill and Large Five Axis Multitasking Equipment. In addition, our normal yearly commitments to employee recruitment, retention, development, and training will continue uninterrupted along with a very solid continuous improvement mindset. This, along with the firm foundation provided by our quality management system and our continued commitment to company culture assures that all is well at Astro Machine in 2023 and beyond!

So, bring on the New Year! Our focus is, was, and always will be, continuous improvement and growth to serve our growing customer base and to manage the ever-increasing levels of sophistication our customer’s demand. As a 100% employee-owned company, our commitment to customer satisfaction has never been greater!

In conclusion, we say from our team to yours; “We look very forward to providing continued support to our growing customer base in the upcoming year”. We at Astro thank you, our customer, for the confidence you have shown in us and your continued business throughout 2022!

We wish continued growth and prosperity to you and your organization and look forward to working with you again in 2023!

Ⅰ. Reasons for damage to the extruder screw

1. The temperature of raw materials is low when plasticizing.

2. The raw material is mixed with metal foreign matter or there are many impurities in the raw material.

3. The extruder screw is running for too long.

4. Unreasonable selection of screw materials.

5. The screw manufacturing precision is low, and the heat treatment hardness of the thread working surface is low.

Ⅱ. The disassembly sequence of the extruder screw

Special tools should be used when the screw is disassembled, and no heavy hammer is allowed. The specific disassembly steps are as follows:

1. Remove the nozzle and the connection between the nozzle and the extruder barrel.

2. Separate the key connection at the rear of the extruder screw elements from the drive shaft.

3. Remove the connecting flange and move the screw of the extruder forward.

4. When the screw head of the extruder is exposed to the barrel, immediately remove the screw head connecting thread (note: the threads here are generally left-handed).

5. Remove the check ring and sealing ring on the screw.

6. The disassembled nozzle, check ring, sealing ring and screw should be cleaned immediately with copper brushes and shovel tools while it is still hot. The special hard-to-clean sticky material should be heated in an oven at the lowest temperature that can soften the material, and then remove the residual material.

7. Assemble the parts on the screw of the extruder together, and apply molybdenum disulfide heat-resistant grease to each threaded connection part to facilitate the next disassembly.

8. After cleaning the surface of the screw that is not in use, apply protective oil, wrap it well, and hang it in a ventilated and safe place.

Ⅲ. Repair and replacement of extruder screw

1. If there is slight wear or scratches on the working surface of the extruder screw, you can use oil stone or fine emery cloth to grind and polish the damaged parts.

2. When the working surface of the screw is seriously worn and the scar groove is deep, the cause of the screw wear should be checked and analyzed, and the fault should be eliminated to avoid similar phenomena again, and then repair the deep scar groove.

If the thread of the entire extruder screw is severely worn, the matching gap between the screw and the barrel increases, the melt leakage increases during operation, and the injection volume is unstable, the outer circle of the screw thread should be thermally sprayed with wear-resistant alloy, and then According to the actual size of the inner diameter of the barrel, the screw grinding is carried out according to the requirements of the fitting clearance of the parts.

If the barrel of the extruder is seriously worn, the diameter of the inner hole increases after repair, and the grinding of the screw after spraying can no longer meet the requirements of the matching gap between the barrel and the screw, the screw should be remanufactured. The thread outer diameter of the screw should be processed according to the matching clearance requirements of the two parts and the actual inner hole diameter of the barrel.

LESUN is a leading extruder spare parts manufacturer in China, providing screws element and screw barrels. The extruder screw types include conveying screw element, kneading screw element, mixing screw element, etc;  Screw barrels include extruder closed screw barrel, extruder closed screw barrel, extruder feed barrel, extruder side-feed barrels, etc. Custom service is available. Meanwhile, we also provide surveying and mapping business as well as processing business for accessories made by major extruding machine companies. Feel free to contact us.

St Étienne co-President Roland Romeyer told Canal + last night that he does not want to sign soon to be free agent Mario Balotelli.

“Could we sign him? Of course. But would we do it? I do not think so. When you take into account the values of the club, our work with Christophe (Galtier) and his entire team, he is not the type of player that we want.”
