The good intake design layer is especially important with the hand-held concrete grinder angle grinder with diamond grinding wheels are provided, because their high-speed operation can cause a dangerous cloud of dust in a matter of seconds, leading the disease can silicosis.
To reduce the risk of silicosis, it is best to cement dust emissions at source, as it can rely on personal protective equipment should be avoided.
When used as a hand-grinderConcrete Grinder or a well-designed polished concrete dust collection shroud, productivity, eliminating the dust, as it is produced, clean up the costly will be to increase later.
With a suitable vacuum extraction of dust not only the entry of ambient air is prevented, it is also taken up and stored in a recording for easy disposal, sweep the floor or vacuuming save.
Tires are less flexible, efficient
The dust that surroundsHoles at the top to allow air to enter a rule to use less efficient and more difficult, because the holes are there to suck down or stick vacuum, which is common when the body flexible sheath touching the ground around the perimeter of. Without these holes to stop the size of the cover will pull down on the floor makes it impossible to move. The holes must find a balance between adequate air circulation around the perimeter to the ground without pulling too hard to continue to produce.This means that only the premature wear of the lining around the perimeter of the body and intake filter dust collection irregularly vary the flow of air, since their filters block over gradually.
The other problem is that the air in the top panel of nowhere, the removal of dust on the floor helps. All the air that comes immediately to cover holes in the top of the socket that is connected to the tube dust collector to transmit, with the support ofCollection of dust from the ground where it is produced.
Better than the shroud for hand grinders concrete have all the airflow shroud the walls near the floor with a constant distance so that the high speed air flow entering the bottom of cement dust accumulates in where it is produced in directing and maintaining the powder suspended because of the outflow. Nothing should touch the ground with the exception of the wheel, and this system will actually remove the dust withoutescape, with a very varied range of air flow through the filter dust gradually over the block. Drain down is never a problem, but a fixed height gap is not as good as a lack of adjustment required.
Stainless steel shroud with an adjustable seal is better
If a shroud is in close contact with the sander and the body is made rigid, long-wearing rubber seal adjustable steel can be used when the height may be selected for optimal performance. These covers are the mostThe gaskets are durable and efficient.
These shrouds are now collecting dust over smooth concrete is increasingly popular, and the edges of the walls of the ground by hand with each new step finer wheels diamond, which it uses to generate a dozen for the best result.
