Conveyers are designed for the continuous or intermittent conveyance of loosen or fine-piece material with granularity of 60 mm. The maximum granularity of 150 mm is allowed under the condition that its occasional occurrence does not exceed 5 % of the total content. Conveyers can be used individually or as part of a transport line. Conveyers serve for conveying hot materials up to maximum temperature 50°C. Aggressive materials shorten their service life.
