Frequently asked questions

Below is a list of our Frequently Asked Questions to date.

If you have something to ask that isn’t included on the list, please don’t hesitate to contact us.

Q: Does the screening unit crush?

A: Yes, The MISU screen will crush soft rock type material only, eg. lime, gypsum, salt, coal and breakdown materials such as manure and mudstone to a finer product. All new units have an adjustable side rake system to assist with this process, moving the rakes forward for screening and back for crushing.

Q:  How much material will the MISU unit screen?

A: We are unable to state specific productivity rates, due to the many variables such as:

  1. Plasticity of the material
  2. Moisture content of the material
  3. Operator skill
  4. Hydraulic horse power of the carrier
  5. Site layout & conditions

However, please refer to our performace page for conservative estimates under normal conditions for dry free flowing material.

Q: What is the wear rate of screening rotors?

A: Rotor blades are made of a heavy duty abrasive resistant plate, with wear rate dependant upon abrasiveness of the material screened.

From our experiences, material such as mudstone is very abrasive and can expect to require hard facing of rotor blades every 300 to 500 hours.

Topsoils and mulches are considerably less abrasive and may only require hard facing from 1500 hours.

Q: Will the MISU unit fit my machine?

A: MISU screening unit pick ups are fabricated to the carrier specifications. Details of pick up specifications are requested at the time of placing the order.

Q: Will the MISU screen finer than 20mm?

A: No, 20mm is the finest screening size available from the MISU product range, due to the intermeshing of rotor blades of 10mm thickness.

Q: Does the MISU screen handle wet materials?

A: Yes, the MISU screen can process material with high moisture content that conventional screening plants cannot normally handle.

Q: What are the unit maintenance requirements?

A: Maintenance requirements are all outlined in the MISU operators manual, however, the main maintenance procedures involve lubing chains every 50 hours and greasing of bearings each 8 hours of operation. We are always happy to help you with any maintenance requirements or questions that you have as well.
