The fine crusher is designed to reduce the particle size of meat and bone; this allows for a more efficient drying process. Conveyor Industries were engaged to incorporate the new fine crusher

to be installed with negligible modifications to the surrounding platforms and equipment, allowing the Conveyor Industries site team to complete the installation with minimal disruption to the plant’s processing schedule. “The ability to work through these layouts using our 3D modeling software and involve our client throughout the process aided in identifying issues that could have developed into problems during the

into their existing system. This involved modifying two shaftless screw conveyors that delivered product to a surge bin, replacing the surge bin and corroded support structure, and supplying the screw conveying system on the discharge side of the fine crusher. The planning required close attention to a range of existing plant, equipment and structures to ensure there were no compromises to access for maintenance personnel and plant operators. The project required detailed site surveying, creating 3D layouts to thoroughly explore various bin designs to maximize the capacity within the available space.

Aerobelt® Manufacture Following our recent announcement regarding the manufacturing license we have secured for the Aerobelt® conveyor, we are pleased to advise that we have successfully completed the manufacture of two Aerobelt® conveyors.

The installed power of the Aerobelt® is less than half of what the ‘en-mass’ conveyor absorbed, and as there are few moving parts maintenance costs are expected to be minimal. Since itsi nstallation and commissioning in February 2011 EFI are now considering replacing other high maintenance conveyors with the Aerobelt® conveyor.

The first has been installed and commissioned for Energy for Industry (EFI) at the Winstone Pulp International site in Karioi, New Zealand.

The second Aerobelt® has been exported to Vietnam.

This Aerobelt® conveyor has been designed to conveyor wood-waste and sludge at a combined rate of 21 TPH, the conveyor operates at a 25 degree inclination and is used on an almost continuous basis to supply fuel to the boilers multi screw surge bin.

It is to be used for the conveying of fine wood chip and sawdwust for a new particle board plant currently being constructed in the vicinty of Ho-Chi-Min City.

Due to the abrasive nature of the contaminants within the wood-waste, significant on-going maintenance of the existing conveyor - an ‘en-mass’ chain conveyor - resulted.

The Aerobelt® conveyor is part of a system we have designed and manufactured which includes a ‘live bottom’ (multi screw) storage hopper and collection screw which feeds a large rotary valve and pneumatic conveying system.

EFI were looking for a conveyor that would provide a very high level of availability and to significantly reduce their running & maintenance costs.

The conveyor system is scheduled to be installed mid 2011. Both the installation and commissioning will be under our supervision.

Expanding Our Manufacturing The installation of our second overhead gantry has not only provided greater efficiency in our workshop fabrication division, it has also allowed for the expansion of our manufacturing capability.

Demonstrating our increased capability and competitiveness, we have recently completed two projects which included the fabrication of two hoppers with integral conveying systems for the re-circulation and discharging of their respective products.

The second gantry enables us to manufacture larger items which previously proved difficult without the ability to manipulate the item from two points.

Being centrally located in the North Island (and close to the Port of Tauranga) enables us to fabricate, paint, assemble and test run prior to transporting to site anywhere in New Zealand, or overseas, and retain competitive pricing.

With both gantries being ‘remote’ control operated, the safety of our workshop team has been increased by having more control over these objects.

Sensor Installation Made Easy

Conveyor Industries now stock the revolutionary Whirligig rotation sensor. The sensor bolts to the whirligig base plate and the complete assembly then bolts to the rotating shaft. Shaft or machine vibration does not affect the performance of the sensor as the whole assembly moves with the shaft.

Easy installation choose one of two methods: Attach to a M12 tapped hole in the machines shaft or,

Graeme Lowe Waikato selected Conveyor Industries to design and manufacture new technology to better utilise their meat and bone meal processing in Tuakau, in the Auckland region.

They had purchased a new drier and hammermill, but needed a means of moving the dried product from the new drier to storage and then through a hammer mill and sieve. A new building had been erected so the new system was designed to utilize the interior space to maximum efficiency. The system design and the conveying equipment provided the quality, the competitive pricing (against asian manufacturers), and met a short delivery time. 3D modeling of the system and equipment allowed Conveyor industries to identify potential spatial inconsistencies within the building envelope, and to resolve them prior to design sign-off. This process identified that some machinery needed to be delivered in modules, and assembled on site and

within the building, to enable correct fitment. The new system design needed to maximise the available space inside the new building and some components were made in sections to fit through the existing door and assembled inside.

Use the magnetic connector - this device screws into the whirligig and magnetically couples to the shaft being monitored.

Blockage Sensors

Installation and assembly of this complex system was completed on time and on budget. Once again, the benefits of integrating design, manufacture and installation of complex systems proved economic and efficient for the customer. For decting dry bulk granular material in bins, silos, hoppers & chutes with adjustable sensitivity. The simple but robust point level indicator has no moving parts; its self contained with all potted electronics and can be used in areas of high vibration. Supplied with a polyethylene abrasion shield and ATEX approved these units are simple to install on the sides or tops of steel bins/hoppers and are small enough to be used as plug detectors in discharge chutes.

Experts in the Design & Manufacture of Screw Conveyor Systems

We are located in new purpose built premises in the new Papamoa Junction industrial zone, Bay of Plenty, New Zealand. The workshop is serviced by two five tonne remote control overhead gantries, and includes machine shop facilities, profile cutting, specialised auger manufacturing equipment and other general engineering equipment for the fabrication of both stainless and mild steel.

Auckland Meat Processors Auckland Meat Processors (AMP) approached Conveyor Industries to identify the most economical options for the removal of their renderable raw material and paunch from their new Offal Floor. The conveying system was designed to fill two skip bins with the raw material, and another bin with dewatered paunch. Due to the very limited space available the project required extensive use of 3D modeling and online meetings to develop the layout and ensure adequate access for future maintenance was addressed, along with functionality for the operators.

The products would then be conveyed to a series of incline screw conveyors before reaching the skip bins. Renderable raw material from existing mutton and beef slaughter rooms can also be added to the conveying system, minimising the skip bins and pick up points for the transport operators. To gain maximum efficiency in the processing rooms the system needed to operate without any delays. To achieve this an automated diverter chute was installed- which will switch between the two skip bins - allowing each bin to fill to its full capacity before being removed for rendering. The paunch line includes a screw press to dewater at a rate of one paunch every 30 seconds. The

Once all issues were addressed allowing the layout to be completed, the structural engineer was able to fine tune the building envelope to accommodate the new conveying system.

to the raw material bins to allow for maintenance work to be carried out on the conveyors while the system is still operating. The paunch bins can be wheeled out of the way allowing for easy change over.

The system utilizes two separate conveying lines, one for renderable raw material and one for paunch. Twin collector screw conveyors were set into the floor to allow for unrestricted access for the offal floor staff.

Cleaning of the system was of a high priority for AMP; all conveyors were constructed from a chrome plate (3cr12) which provides a high resistance against wear while still providing an acceptable sanitary finish.

The twin screws where designed to segragate the raw material and paunch to ensure cross contamination was not possible.

Stainless steel pipe lids were incorporated to create an operator friendly environment and allow for the daily clean down process without the need to remove lids.
