Mineral Wool Shredding Solution: How to Choose the Right Shredder for Floor-Level Feeding and Blow-In Insulation

A customer contacted PROSINO team looking for a compact and practical solution to shred mineral wool near an existing cut center.

The customer was particularly interested in a double shaft shredder, but the available installation space was limited. Another important requirement was easy operator feeding. The customer wanted to avoid stairs or an elevated feeding platform and preferred a solution where the operator could throw mineral wool material directly into the machine from a standing position.

After shredding, the processed mineral wool would be bagged for use as blow-in insulation.

This case study explains the customer's requirements, the technical factors considered by PROSINO, and three possible equipment solutions: a single shaft shredder, double shaft shredder, or granulator.

Customer Requirements for Mineral Wool Shredding

The customer's main requirements were:

Material: Mineral wool
Installation location: Near an existing cut center
Available space: Limited
Preferred machine: Double shaft shredder
Feeding requirement: Floor-level manual feeding without stairs
Operator preference: Throw material into the machine while standing
Final application: Bagging processed material for blow-in insulation

These requirements created an important equipment-selection challenge.

The shredder needed to provide sufficient processing capacity while maintaining a practical feed height. In many industrial shredding applications, a large hopper can make material loading easier from above but may require operators to use stairs or a feeding platform.

For this project, operator accessibility and installation height were as important as shredding capacity.

Information Required Before Selecting the Machine

Mineral wool can vary significantly in size, density, condition, and form. It may be supplied as boards, blocks, offcuts, rolls, or production waste.

To recommend the most suitable PROSINO machine and prepare an accurate quotation, the following information is required:

1. Photos of the Mineral Wool Material

Actual photos allow our engineers to evaluate:

Approximate material dimensions
Thickness
Density and structure
Material condition
Whether the material consists of boards, blocks, offcuts, or other forms

Material photos are particularly important when selecting the appropriate hopper size, cutting chamber configuration, and feeding method.

2. Required Production Capacity

The required throughput should be specified in:

lbs/hr or kg/hr

The required capacity directly influences the recommended machine size and motor configuration.

3. Required Output Size

The customer should also specify whether the final material size must meet a particular requirement.

For example:

Is a relatively coarse shredded output acceptable?
Is a more uniform particle size required?
Will the processed mineral wool be used directly for bagging?
Is the material required to pass through a specific screen size?

The answer to these questions helps determine whether a shredder or granulator is the better solution.

Comparison: Which Mineral Wool Processing Machine Is Suitable?

Machine	Suitable Application	Approx. Capacity	Output Control	Standard Feed Height
PS-S-2260 Single Shaft Shredder	Mineral wool boards and offcuts	400–600 lbs/hr	Good	Approx. 5.3 ft
PS-D-2160 Double Shaft Shredder	Mineral wool blocks and bulky material	500–700 lbs/hr	Coarser primary shredding	Approx. 6.0 ft
PS-C-M-3261 Granulator	Lower-capacity applications requiring more uniform and smaller output	Depends on material and screen	High	Application-dependent

Important: Actual machine selection should be based on material testing or detailed information about the customer's mineral wool, capacity requirement, output size, available space, and preferred feeding method.

How to Choose the Right Mineral Wool Shredder

For customers with requirements similar to this project, PROSINO generally recommends considering the following factors.

Choose a Single Shaft Shredder If:

You need approximately 400–600 lbs/hr capacity
You process mineral wool boards or offcuts
You want better control over size reduction
Lower manual feeding height is important

Choose a Double Shaft Shredder If:

You process bulky mineral wool blocks
You require approximately 500–700 lbs/hr capacity
You prefer robust primary shredding
You want to avoid stairs where possible
A customized low hopper can be incorporated into the installation

Choose a Granulator If:

Your capacity requirement is relatively low
You require a more uniform and smaller output size
A specific screen size is required
The shredded mineral wool will be bagged after controlled size reduction

Important Consideration: Feeding Height Can Be Customized

One of the key lessons from this project is that machine capacity alone should not determine equipment selection.

For installations near cut centers, operator accessibility can have a significant impact on daily production efficiency.

A machine with a large hopper may provide more loading volume but may also create an inconvenient feed height. For manual loading applications, the customer should specify:

Maximum acceptable feed height
Whether stairs are acceptable
Whether an operator will feed material manually
Typical dimensions of the material being loaded
Available floor space around the machine

PROSINO can evaluate customized options such as a lower hopper and shortened machine support legs to help achieve a more practical feeding position.

From Mineral Wool Waste to Bagged Blow-In Insulation

The proposed processing concept can be summarized as:

Mineral Wool Offcuts / Blocks → Shredding or Granulating → Sized Material → Collection → Bagging

Depending on the required final product, additional equipment may also be considered, such as:

Discharge conveyors
Material collection systems
Air conveying systems
Dust control equipment
Bagging equipment

The complete system configuration should be determined according to the customer's production process, final material requirements, and available installation space.

Request a Mineral Wool Shredding Solution

Are you processing mineral wool, glass wool, mineral fiber, insulation offcuts, or similar production waste?

To receive a suitable machine recommendation and quotation, please send PROSINO:

Photos or videos of your material
Material dimensions
Required production capacity in lbs/hr or kg/hr
Required output size
Maximum acceptable feeding height
Available installation space
Whether the processed material will be bagged or further processed

With this information, PROSINO can recommend a suitable single shaft shredder, double shaft shredder, or granulator and evaluate whether a customized low-feed design is required.

Mineral Wool Shredder

2023/03/24

A mineral wool shredder is a machine that is designed to shred or crush mineral wool, which is a type of insulation material made from natural or synthetic minerals such as basalt or slag. The machine is typically used in industrial settings where large quantities of mineral wool waste are generated, such as construction sites or manufacturing facilities.

Stone Wool Shredder

Shredding stone wool is an essential step for recycling and volume reduction. A stone wool shredder can break down bulky stone wool waste into smaller, more manageable particles. This offers several benefits.

Glass Wool Shredding Machine

2023/07/03

Glass wool, also known as fiberglass insulation, is a widely used thermal and acoustic insulation material in various industries such as in buildings, industrial applications, and appliances. While glass wool offers excellent insulation properties, its disposal and recycling present unique challenges due to its fibrous and delicate nature. To address these challenges, the development of glass wool shredding machines has revolutionized the recycling and waste management process. These machines efficiently shred glass wool insulation, enabling volume reduction, improved handling, and promoting recycling efforts.
