New Centrifugal Impact Mill Grinds & De-Lumps

UTICA, NY -- A new 24-inch (610 mm) sanitary stainless steel Centrifugal Impact Mill Model CIM-24-SS from Munson Machinery provides coarse to fine grinding (325 mesh) of friable materials into controlled particle sizes, as well as lump breaking and conditioning of fibrous materials.

High speed rotation of the inner disc creates centrifugal force that accelerates bulk material entering the central inlet of the opposing stationary disc. As material travels from the center to the periphery of the discs at high speed, it passes through a "treacherous path" of five intermeshing rows of rotating and stationary pins, with the desired tight particle size distribution obtained by controlling the rotor speed.

Setting the infinitely variable rotor speed between several hundred rpm and 5400 rpm provides the flexibility to use the machine for coarse grinding and de-agglomerating as well as for fine grinding.

Also called a “Pin Mill”, the unit is said to handle wet or dry materials, to produce tight particle size distribution at any given rotor speed setting, and to sanitize rapidly.

According to the manufacturer, the unit provides high throughput rates per horsepower relative to machines employing screens, hammers, knives or rolls, depending on application.

Other size reduction equipment offered by the company includes screen classifying cutters, rotary de-clumpers, attrition mills, hammer mills and shredders. Blending equipment also produced by the company includes ribbon, paddle and plow blenders, rotary batch mixers, rotary continuous mixers, high intensity blenders and Forberg mixers.

Buhler Group : Loading Follows Unloading

Uzwil, Switzerland -- Economic progress is yielding results: The Buhler Grain Handling business unit is now also installing ship loading systems in China beside the ship unloaders supplied up to now.

The port of Beiliang is located near the international sea port city of Dalian in the northeast of China. It is strategically located, boasting excellent road, rail, and air links. At present, the port has ten berths for ocean-going vessels, including docks for grain, petrochemicals, and vegetables plus one multipurpose berth each for containers and general commodities. The port of Beiliang handles 28 million metric tons of goods every year.

A number of world-class grain terminals for storing and handling grain are situated just next to the berths for grain ships. This entire “grain complex” consists of three large docks for grain handling, a grain terminal elevator with a holding capacity of 870,000 metric tons, and a national grain warehouse that holds 600,000 tons.

For overland transportation, a total of 2400 hopper cars are available in four marshaling yards, in addition to over 40 trucks for road shipments. The facility is also equipped with control and test systems, proportioning installations, a complete automatic control system, an information management system, and other installations for handling and weighing bulk materials.

The maximum capacity of the grain transshipping facility for unloading rail vehicles and loading ships is 4000 metric tons an hour. That for unloading ships amounts to 2000 tons per hour, and for loading rail vehicles 1000 tons per hour. The annual grain handling volume amounts to 12 million metric tons.

First Loader from Buhler

In early 2005, the Beiliang port authority decided to increase loading capacity by adding two more ship loaders. The goal was to optimize operations and to create a possibility to simultaneously load ships with different materials at two different piers. As part of this expansion project, the port authority decided to install two Buhler ship loaders provided with advanced equipment and reflecting the state of the art – the first such units to be supplied to a customer in China. These mechanical loaders operate continuously with a throughput of 1000 metric tons per hour each.

The two new ship loaders are equipped with loading head dust suppressors. Throughout the loading operation, these units effectively suppress dust emissions, keeping the surroundings clean and ensuring compliance with environmental protection regulations. The effectiveness of this dust control system has proved to be higher than that of systems applied on other ship loaders.

In addition, the two facilities also have a state-of-the-art automatic system for the remote control of all operations. Other features include various installations for ensuring safe and reliable operation. The entire installation is provided with a dependable quality assurance system from design features to main components.

Parts of the loaders were manufactured in China under the Buhler quality assurance system. The two new loaders from Buhler have definitely improved the efficiency and quality of ship loading in the port of Beiliang.

Buhler is a global Technology Group and a system partner for the supply of plant, equipment, and process know-how in the fields of Food Processing, Chemical Engineering, and Die Casting, with some 6,000 employees worldwide.

Mr. Lacy wants info on a "static" screw conveyor:

I am looking for a piece of equipment to elevate a mixture of dry products about 20 feet. We have tried several different technologies with varying degrees of success, but have not found the "ideal" solution.

We have tried the bucket elevator, "Z" belt conveyor, standard screw conveyor, vertical screw, and shaftless screw. Does anyone have experience with the static screw? How does it work? The material is a mixture of cement, plaster, perlite, vermiculite, limestone, and similar materials.

It is critical to the operation that the powders do not segregate.

Mr. Falcioni needs help with conveying vent valve:

I have a question on pneumatic conveying. We have a very abrasive material (many times more abrasive than cement) that is pneumatically conveyed into a transport vessel or pot. These pots pressurize and send the material to bins downstream. I am sure that this system is pretty standard in the pneumatic conveying world.

My question deals with the vent line on the pot, which opens at the beginning of this cycle to vent the system. The present valve in place is a butterfly valve which see extremes wear and fails every 2.5 months. It appears that the valve fails in the areas which will see the highest velocity on both the disc and the seat when the valve opens.

Is there any other type of valve that would be more appropriate for this application?  (to post reply, click here)

Thanks very much,
