Factory made hot-sale Har-821/802 Driving Machining – China Manufacturer

The Continuous Screen Grader offers a relatively inexpensive machine, alternative to the Lift Roller Grader. This system uses a traveling mesh screen to separate produce into different sizes. If the produce is small enough, it will pass through the screen. Larger produce will progress to the end of the machine. Oversize produce is fed to screen grader for next grading.The process can be repeated, and multiple sizing achieved, simply by adding additional Screen grader modules. Sizing efficiency is further aided by mechanical shakers that gently vibrate the produce on the screen.
Each grader module is provided with cross belt conveyors to carry sized produce away for further processing.

Salient Features:

Modules can cater for up to 20 tones per hour, depending on the produce variety
Main frame constructed from mild steel, galvanized or painted or stainless steel
G.I. Wire mesh or S.S. wire mesh of required size opening is supplied.
Screen hole size can be matched to your sizing requirements
Anti-cut rollers run underneath the screen to ensure produce does not become trapped in the mesh.
Cross belt conveyors supplied.-

We are proud to introduce a new type of production platform.
The BLACKBELT 3D Printer allows you to produce special and endless geometries in series production.

Changing paradigms in 3D printing

Print continuously / series production
Print specifically designed overhangs without additional support material
Print extraordinary long parts

Design Guidelines:

BlackBelt 3D offers the user new possibilities that standard XYZ printers cannot deliver. New shapes are possible, meaning new design guidelines for users of the BLACKBELT 3D Printer. Here’s the first designer’s guide to using this technology.

What we CAN do:

We can build up material on the conveyor belt or on previously printed layers. The 45° slanted layering allows printing horizontal overhangs that don’t require support material.

This example shows a txpe of overhang, which requires support material on regular 3D printers. With the BLACKELT, this is not nessecary anymore.

Still, we are not able to print into thin air. The BLACKBELT 3D Printer must start every new geometry on the conveyor belt or onto a previous layer of the workpiece.

If the model starts above the conveyor belt, a gap arises to the conveyor belt. That’s why some geometries require a starting geometry.

Technical specifications

We are using carefully selected components that have proven to be reliable and work with the best performance. Among these are a specially designed extruder and feeding system, high quality electronic boards, motors and actuation system. Using a full metal frame made from BOSCH aluminum beam Profiles and stainless steel sheet metal parts provide a rigid construction and also makes customization easy.

The entire design of the BLACKBELT 3D Printer has been engineered in SolidWorks CAD, allowing detailed construction and parametric design.

Customizable modular design

The BLACKBELT 3D Printer is designed to adapt different environments for example like production facilities or R&D departments. It can Produce large prints or many parts in series, using a variety of materials. We can customize the machine to meet your individual requirements: as desktop version or stand-alone.

The machine comes with easily interchangeable print heads to allow a flexible adaptation to different printing requirements.

We understand that different industries require different machine set-ups. This is why we also offer additional modules like a roller table for extra-long products, a stand-alone frame containing a spool storage rack or a variety of different print heads that are adaptable to the BLACKBELT 3D Printer. Get in touch with us to get an offer for those extras!

Belt technology

The carbon fiber composite conveyor belt has proven to be durable and provides necessary surface adhesion to print on. Its intrinsic stiffness and low thermal expansion coefficient allow precise positioning and great interfacing of the product that is being built, which makes it the perfect material for this application – plus, it looks great; which gave the BLACKBELT its name!
