ACA crusher for recycling of gypsum waste from demolition and recycling stations
Crushing of gypsum waste and residue for recycling. The machine crushes recyclable gypsum, gypsum residue, gypsum waste from demolition and gypsum collected from recycling centres and renovation sites. The crusher crushes the gypsum and separates it from paper, insulation materials, steel rods, plastic, wood, cables, nails and screws for subsequent removal. After removing paper, insulation materials, steel rods, wood, nails, screws, cables, etc., the gypsum can be reused to produce new plasterboards. The ACA crusher manages crushing the gypsum without creating paper contamination in the final gypsum product. The ACA crusher is very cheap in operation, is suitable for continuous 24/7 operation and has a large capacity.
Input: gypsum waste
Recycling of gypsum from recycling centres
ACA crusher for recycling of gypsum waste and gypsum residue from recycling stations and collection points for improved recycling.
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.
Recycling of gypsum waste
The crusher crushes the gypsum and separates it from foreign bodies such as paper, insulation materials, steel rails, plastic, wood, nails and screws, which will subsequently be removed.
Slow-turning crusher for gypsum recycling
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.

Effective crusher for gypsum recycling
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.
Safe and reliable crusher for crushing of gypsum
With a substantial weight of up to 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 operation in the company is assured.
Cheap in operation
The machine’s movable parts do not touch each other, which guarantees a long useful life of the parts, as the plasterboard / gypsum residue is crushed against itself, thereby separating the gypsum from the paper and metal components, which will be sorted later.
ACA crusher in operation
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.
Unpolluted crushed gypsum
The ACA crusher manages crushing the gypsum without creating paper contamination in the final gypsum product, so it can later be reused to make new plasterboards.
Adjustment to requirements
An ACA crusher can be adapted to the customer’s requirements, so that the machine is supplied in the size that is most economical for the customer and best suited for the task at hand. The crusher is designed to operate around the clock, so it is an advantage to choose a machine that will allow you to maximise use of the capacity for as many hours as possible. In other words, there is no reason to choose the biggest model with 12 screws if you can use a smaller model. Conversely, a small model can be extended if the need for capacity increases.
Recycling is in keeping with the times
It is in keeping with the times to maximise the recycling of gypsum waste. In its guiding opinion from autumn 2015, the Danish Environmental Protection Agency recommends, among other things, that gypsum be recycled or reused. The difference is whether the gypsum is crushed before being reused or whether the plasterboard can be used as is for a different purpose.
In addition to being used for new plasterboards, the crushed gypsum can also be used in the production of cement. It can also be used in compost or for screening purposes. Studies performed by the Danish Environmental Protection Agency show, however, that the best environmental profile is obtained by using the crushed gypsum for new plasterboards or in the production of cement.
Gypsum is a natural material that is mined in in countries in its original form. A large part of the gypsum used for plasterboards in the industrial sector nevertheless comes from cogeneration plants.
These plants produce gypsum when using lime to clean and neutralise the smoke. This gypsum can then be used in the production of plasterboards at the factories.
Another feature of gypsum is that used plasterboards, cut-offs and other gypsum waste, for example from demolition work, can be crushed and used again in the production of new plasterboards. Plasterboard is thus a natural product which, in addition to forming part of the life cycle of new gypsum products, can also help reduce the environmental impact from cogeneration plants.
ACA crushers for gypsum products play an active role in this recycling process. The crusher is relevant both at recycling centres, where plasterboards are collected and the raw material can be supplied to plasterboard factories, and at demolition companies that sell various fractions.
Crushers are also used at various plasterboard factories to crush faulty products or unsaleable gypsum residue without having to transport the plasterboard to an external demolition company.
Gypsum after screening
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.
Metal eliminated from recyclable gypsum
Efter sigtning af gipsen har man en jernfraktion bestående af frasorteret jern, skruer, stålskinner, metalrammer, jern beslag og søm. Disse dele ødelægger ikke maskinen og kan sendes til senere genanvendelse
