Crusher for recycling of plasterboards and production waste for use in the production of new plasterboards. The crusher is particularly suited for the crushing of gypsum without creating paper contamination in the final gypsum product. This applies to plasterboards, production waste as well as offcuts from new plasterboards. The ACA crusher crushes the gypsum and separates it from the paper, which is later removed. Once the paper has been removed, the gypsum can be used in the production of new plasterboards. The ACA crusher is a slow-turning machine, which is both very strong and very economical. The size of the output can be adjusted as desired.
ACA crusher for recycling of faulty production of plasterboards from gypsum manufacturers in 24/7 operation.
The ACA crusher is fitted with a large hopper which is adjusted to the customer’s requirements. The waste can easily be loaded into the hopper with the help of a Digger or from a conveyor belt.
The ACA crusher is available in various versions. The crusher can be supplied in standard sizes with 2, 3, 4, 6, 8, or 10 screws depending on the size of the input material and the desired amount of output.
The crusher crushes the gypsum and separates it from cardboard and paper in order to use it in the production of new plasterboards.
The crusher produces an even flow of output. This makes it much easier to optimise the subsequent screening of the material to suit the rest of the production process.
The crusher is fitted with a large hopper which is adjusted to the customer’s requirements. The waste can easily be loaded into the hopper with the help of a Digger or from a conveyor belt.
The ACA crusher is a slow-turning machine operating at 15 RPM per minute with a torque of 13,000 newton metres per screw, even at this low number of revolutions. The amount of dust produced is therefore limited.
With a weight of between 5 and 20 tonnes, a torque of 13,000 newton metres and reverse operation in the event of excess current, breakdown of the crusher can be avoided, and many years of useful life and safe, reliable 24/7 operation in the company is assured.
As the machine is slow-turning, the noise level is as low as 75 DB when the machine is empty. The only thing you hear is the cooling of the machine.
The machine’s movable parts do not touch each other, which guarantees a long useful life of the parts, as the plasterboards are crushed against each other, thereby separating the gypsum and the paper for subsequent sorting.
The ACA crusher’s flexible design makes it easy for the user to regulate the size of the output material by adjusting the rotating knives. The knives are easy to replace.
The crusher is extremely well suited for the crushing of gypsum withoutcreating paper (fiber) contamination in the final gypsum product. This applies to plasterboards, production waste and offcuts from new plasterboards, which can subsequently be used in the production of new plasterboards.
The recycling of material plays an increasing role in modern society both from a financial point of view and out of concern for the climate and the environment, as it is uneconomical and unsustainable to only use virgin materials. The use of gypsum in the production of new plasterboards thus presents many advantages, and all types of gypsum can be recycled.
Modern plasterboards are a very broad-spectrum product. In some cases, different molecules and substances may be added to make the plasterboard actively absorb and release heat, which means that the plasterboard can play a role in regulating the indoor temperature in office environments. This type of gypsum can still be recycled, so the more gypsum waste and offcuts that can be collected for recycling, the better.
The crusher separates gypsum, paper and other materials, if any, producing a very pure fraction that is highly suitable for further recycling.
This separation of paper, fibre and pure gypsum determines the degree to which the gypsum output from the crusher can be recycled.
The paper can also be used in the production of new paper, but another option is to send it to an incineration plant, where it will contribute to the production of CO2-neutral electricity and heating.
Screened gypsum ready to be recycled as new plasterboards
After screening of the crushed material you are typically left with three fractions: gypsum, paper and metal.
Gypsum paper after screening
The screening of the gypsum leaves behind large pieces of paper with bits of gypsum attached, which can be recycled later.
