M Z H H a m m e r m i l lThe Dual Rotation Multi-Zone Hammermill consistof a double radius cutting plate with staggered slot-ted rows and offset rotor with 3/16” hammer tocutting plate clearance. The cutting plates offer sig-nificant size reduction prior to the products contactto the screen making size reduction more effective. The MZH is an excellent pre-grinder in demanding appli-cations and the standard for primary grinding in traditionaloperations.

Offering complete grinding solutions to the aquafeed industry for over 50 years, Jacobson currently supplies the topaquafeed manufacturers of the world with complete size reduction solutions.

C o m m a n d e rThe fine grinding Commander Hammermill is well suited to theaquafeed industry’s move toward finer ground ingredients.This mill has proven itself in the fine grinding of higher fat for-mulations on 2.0 mm or smaller screen sizes.

The 2.5 mm tip to screen clearance is maintained around theentire grinding chamber. The staggered head plate rotor pro-vides complete hammer coverage of the screen while the man-ganese hardfaced cutting plate breaks up harder materials con-tained in most aquafeed diets. These features, along with aproperly designed removal system will produce fine, clean, andsteady outputs in Aquafeed applications.

The industries move toward this increasing complex diets andfine particle sizes include the need to maintain water quality andimproved digestibility. The ASP mill is the worldwide standardfor eel, shrimp, and fin fish applications. This screenless finegrinder works well on the most demanding aquafeed applica-tions.

B e n e f i t s o f J a c o b s o n A i rS w e p t P u l v e r i z e rParticle Size - Optimum reduction in the medium to microfinerange, producing powders from -20 to -325 mesh.

Product Yield - Continuous three-way milling and recycle grindingplus pneumatic conveyance assure steady output. Mill specificationsvary to fit characteristics of materials.

Easy of Maintenance - The Jacobson ASP is undoubtedly the easiestfine grinder on the market to clean, to change out wear parts, or toservice the drive and bearings.

Contamination - Machines are designed for sanitary operation andcleanliness from feed inlet to discharge.

Temperature Controlled Grinding - The use of an air streamnormally cools the grinding material. When required, refrigeratedair or other gases can be used for temperature control.

Product Uniformity - Internal self-classification and regrindinginsures narrow distribution of particle size and uniformity of output.

Economy of Operation - The basic efficiency of the Air Swept designguarantees an exceptionally favorable ratio of product yield topower consumption, processing time and related production costs.

Flexibility in Grinds - To meet varying grind sizes or millingrequirements for different materials, the Air Swept design allowsfast changeover of grinding and classifying elements.

Dust-Free Operation - Negative air pressure design keeps dust outof the air to eliminate health and plant hazards while resulting inclean conditions around the machine.

Quick Clean-Up - Hinged discharge housing allows easy accessto mill interior and unexcelled simplicity for change of grindingelements or clean-up.

Since producing its first machine in 1910,

Jacobson has become the most complete

single source of size reduction systems in the

world. Offering a broad range of size reduction

equipment to handle such materials as chemicals,

minerals, feeds, pharmaceuticals, frozen prod-

ucts, foods, etc., Jacobson has built a reputa-

tion as a leader by providing top quality equip-

ment while employing the most efficient meth-

ods of product sizing.

Jacobson’s fine grinding is performed in the

screenless Air Swept Pulverizer (ASP) which

uses internal air flow and the largest surface

grinding area of any competitive mill. Since

every material has its own distinct properties,

the Jacobson approach to machinery selection

involves not only a close examination of the

product to be reduced, but also a systems

oriented look at the entire process involved.

The fully equipped Jacobson Test Lab, with its

team of experienced engineers, can thorough-

ly test a product to determine the most effi-

cient machine or system to handle a particular

application.

The world’s leading ASP with internal classification, ourinternal classification system uses practical design principalswhich offer important cost advantages over externalclassifiers. These advantages are as follows:

• Easy to operate• No skilled technician required• No additional power consumption• No costly wear components

In addition, recent design modifications now give betterparticle-size control, allowing you to produce a finer rangeof particles in your final product.

The Jacobson Air Swept Pulverizer featuresa straightforward, efficient design. Itsoperation is as follows: The hammers (4)connected to the beater plates (2) impactand reduce the largest particles (1), anddistribute the material to the periphery ofthe grinding zone. The hammers, which aremounted on the edges of the beater platesrotate between 1,600 and 7,000 rpm with tipspeed velocity ranging from 19,500 (100-175m/sec) to 34,000 feet per minute to grind thematerial against the liner (3). The classifierplate (5) separates the finely ground productfor exit through the discharge outlet (6),while returning oversize material (7) to themill for further processing.

The Jacobson ASP is often the last step insize reduction for spices, aqua feeds, chemi-cals, foods and more—materials which needto be reduced in size from 500 micronsdown to fine particulates below 37 micron.

SYSTEM DESIGNS

GRIND & DRY (OR COOL) SYSTEMSGrind and dry systems are well suited tofinish drying a material while at the sametime reducing material size.

STANDARD SYSTEMSStandard systems use air stream tomove product through the mill in asimple, reliable dust-free operation.

Our belt drive design of our 16H, 22H, 28H and 48H is an extremelylow vibration. Our rigid base is constructed of thick wall tubing provid-ing minimal vibration and twisting.

On both of our drive designs we use a sealed keyed bearinghousing design and protected shaft to seal contact areas pro-vide a highly durable system.

Our shaft seal to case design offers a terrific seal and we can provideadditional shaft seal to case options for special applications.

B e l t D r i v e D e s i g n s

Our Beater plates are laser cut-out to give usthe most precision circle and then laser cutblades are welded on. The plate is thenmachined for tight tolerance.

When carbide is used the tungsten car-bide is silver soldered to the tips and tested withdie penetrant. The beater plate is then re-checked for tight tolerance. We also spin testeach carbide tipped beater plate to test carbidewelds.

When also can provide hard faced beatertips when carbide will not meet your applicationcircumstances.

All of our beater plates are balanced perthe set for minimal vibration. All plates are thenloaded in the machine and test run to insuredynamic balance.

Our liners are made of either hardened steel orstainless steel depending on the application.Each liners outside and inside dimension ismachined for tight fit to the beater plates andhousing. Our wedge design for securing the lin-ers and installation is proven to be the best inthe industry.The liner to beater plate clearances are of thetightest tolerances possible to insure propergrind and operation. We also offer different linertooth styles depending on the application.
