ball mill - retsch - powerful grinding and homogenization

Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry. Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery. Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding to analytical fineness. They are used for the most demanding tasks in the laboratory, from routine sample processing to colloidal grinding and advanced materials development. The drum mill is a type of ball mill suitable for the fine grinding of large feed sizes and large sample volumes.

coach bruno invites kids to his new b-ball court | news, sports, jobs - the express

Although he claims he built the court for himself, theres little doubt that younger hoopsters will be frequent occupants and of course the cement court, although not full-sized, leaves plenty of room for drills of all sorts, not just shooting.

Ive preached for my 35-year teaching and coaching career that in order to give kids the opportunity to make healthy choices and stay away from drugs, you have to give them something to do, Bruno said recently just after the court was built. I had three or four kids out there the day after the concrete was poured. I plan on shooting around myself quite often and Ill always welcome company, he added.

Although the coach does like having the ability to have his players from his Bucktail team always having a place to go on his court, its actually ballers that are a little younger that he feels he can assist, not just with basketball but with life choices they will make down the road.

With so much of his coaching philosophy being adamant that in order for basketball players to build winning programs, having a basketball in their hands year round is a must, Coach Bruno just gave current and future players alike no chance to make any excuses not to do just that.

We are not seeing a problem with the drivers delivering at the plant, the problem is with the residents and bulk trucks, added Lobosky. It would just be safer lowering the speed limit with the movement in and out of the seven entrances to the quarry and the heavy traffic for the expansion project.

The consulting firm will help the county navigate federal and state laws for claiming child support reimbursements. They work with HUD, the Indiana FSSA Department of Child Services and county auditor, clerk, prosecutor and the courts to review claims for accuracy and seek any overlooked allowed reimbursements which can then be used locally.

Butler, Fairman & Seufert, Inc. completed the bridge design for Bridge 138 on Oolitic Road. Holmes will be submitting it for the second round of the Community Crossing funds. The total cost to replace the deck of the bridge is estimated at $750,000.

We are hoping to receive the funding and begin construction in the fall, Holmes added. We used drones and found the bearing pads have shifted to the east. Thankfully they cant move anymore. The plan is to start construction in the fall if we receive funding, if we dont get the award I honestly dont think we will have the money to replace the bridge.

The drones will be used on crime scenes, accident reconstruction and search and rescue, he added. They have speakers so we can talk to those who are lost and direct them out of a location or to communicate with a suspect. They also have heat sensors to locate a missing or lost person or a suspect.

The department is also placing stationary license plate readers throughout the county. The readers will read a license plate and then send an alert to officers in-car computers if that vehicle has been stolen or alert officers of a possible wanted person connected to that license plate. These readers will not address motorist speeding.

Sheriff Branham said once emergency management is finished using the sign trailers, they will then be placed in locations known for motorists exceeding the speed limit. They are equipped with radar and camera imaging to help address speeding motorists.

Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

If time permits and the user wishes, grinding circuits are set up and continuous tests are run to simulate plant operation. These tests require two or three days for each ore type and approximately 1,000 pounds of material for each day of testing. Variations in ore hardness or circuit design may require larger samples.
