ABSTRACT:
Methods and apparatus for loading particulate materials, in particular calcined coke, into a transport vehicle are disclosed, wherein the loading operation under steady state conditions is carried out in a "plugged chute" mode, so that a major portion of the loading chute is maintained in a filled condition with the particulate material being loaded. In this manner, the product drop height is maintained at an acceptably low level so as to reduce the velocity of the particulate material throughout the loading process below a damaging rate and thereby prevent significant degradation of the material. In a preferred embodiment, the major portion of the loading chute comprises a telescoping chute arrangement and level control means located above the major portion of the loading chute is employed to maintain the chute in the plugged or full condition by regulation of the discharge valve when the telescoping chute arrangement is fully extended. Conventional level control means located near the discharge end of the major portion of the chute may be employed during particular phases of the loading operation (in particular, when the telescoping chute arrangement is retracted). Switching means is suitably provided to permit instantaneous change from the plugged chute loading mode to conventional loading.
