Almac Ltd - FAQ

So what is special about Vecoplan Shredders?

Okay, consider these facts
The rotor design with special concave cutting crowns is protected by patent. This means that our crowns are mounted in specially machined pockets incorporated in the V shaped rotor profile instead of being simply welded into the grooves of the profile. The gap between the rotor surface and the counter knife is small.

RESULT:- Material which hasn't been cut cannot penetrate into the screen area. The machine can cope easily with difficult materials such as veneer, foil and paper as well as thin sheet material of various sorts.

Energy saving of up to 30% is achieved with our rotor and cutting crown combination.Competitors usually supply a lower cost basic rotor in which the cutting tools are simply welded into grooves in the rotor with concave cutters only available at extra price These cutters are a free option with Vecoplan.

Vecoplan deliver a rotor system which prevents oversize penetration, eliminates pressure on the screen and prevents friction generated heat. This reduces power requirement thus reducing operating costs.

The Vecoplan VAZ machine has a kinetic trigger installed to protect the motor gear box and reducing system against damage in case oversize stones or iron pieces get into the hopper. Without a safety system like ours you would have to be extra careful about how you filled the hopper.

Vecoplan rotor bearings are mounted in solid steel housings with a specially designed two-stage dust seal. There is a form-lock flanged joint to the machine housing. It is not just some simple bought in cast iron bearing as others use.

What about the Ram system?

Since Vecoplan are an engineering company and manufacture in their own factory, the design team have refined our process system to the top level available and even on our smaller machines the client gets the benefit of the best technology. The Ram travels in specially shaped wear resistant plastics rails with lateral guidance from ball bearing rollers. The technique is designed to give maximum benefit for each individual model and is of increasing strength according to machine capacity.

Ram travel is by two speed hydraulic drive with an independent motor, the feed rate is controlled by continuously monitoring power consumption on the main motor. This means every material is specifically fed at a rate conducive to maximum efficiency.

Is the motor voltage suitable for my supply if you are scanning continuously to get this level of efficiency?

It is: we have the motors wound to your voltage for the very reason that constant scanning requires accurate voltage assessment. It takes a little longer for us to prepare the motors but it pays you back in efficiency, lower running costs and reliability.

So how do you use this information from the motor scan?

The Vecoplan VAZ models 800 and larger are all equipped with a PLC controller with self learning features. The real time monitoring of the motor load and other parameters ensure the automatic adaption of the ram motion with different materials and different conditions.

Screen size changes, for example, require no further adjustments because the PLC ensures that the ram functions with the new parameters automatically compensated for.

You seem to have smaller motors than those fitted by your competitors.

This can be true, we don't need to have oversize motors as the PLC ensures we get best efficiency with the motor fitted as standard. We put motors up to 200 kW on our biggest machines working in the Waste Transfer stations and they will produce up to 20 tonnes an hour from demolition timber! We know the best size motors for the materials screen size and throughput - this comes from experience and design techniques.

Is that everything?

Well, not quite. The Vecoplan is laden with features such as Spring Loaded Ram Seals that prevent material slipping beneath the ram during operation. The machine is made from very heavy and thick plate to withstand constant load and the shaft diameters are massive for the same reason. Spares Service and Customer Liaison are always at the forefront of our sales program.

You see, we build our own machines from our own designs and have literally thousands of machines and systems working around the world. Our reputation is built on the quality of the machinery and the ability of our equipment to deliver a reliable and regular performance in all conditions.

You will find Vecoplan chippers and shredders in Sawmills, Joinery Works, Furniture Factories, Plastics and Waste

Paper Recyclers as well as in Waste Transfer stations, Spoil and Landfill Sites and in Security Shredding Units.

We build full Systems with screening and handling in our own factory and support each installation with Integrity and Efficiency.
