ABSTRACT:
A rotary batch-type grinding mill for processing powder is provided with an improved system for discharging material under seal from the atmosphere. The discharge system comprises a sealable collection chute having a banana-like configuration secured on the mill shell at an outlet port in the shell and extending substantially parallel to the circumference of the shell, a grate which prevents discharge of the grinding media from the mill during unloading of material from the mill and an elastomeric faced sealing plate which covers the grate during operation of the mill. The sealing plate is operated from outside the sealed system so that discharge from the mill can be effected without breaking the seal and the sealing plate is so disposed that in the open position it does not interfere with the flow of powder out of the mill.
