Abstract
Abstract An apparatus for pelletizing powderous materials, such as iron ore and alumina, the apparatus including rows of vibrating trough-like members, each row being spaced below the preceding row so that primary pellets fed into the apparatus pass from the top row to the bottom row of trough-like members and are formed into hard pellets.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
Apparatus for pelletizing powderous materials including: a. means for heating primary pellets formed from said powderous material and a binder and a feeding them to vibratile means comprising a plurality of troughlike members forming a path for movement of said primary pellets therealong; and b. vibrator means capable of causing said troughlike members to vibrate at approximately 20* to the horizontal, the plane of vibration being at an angle of approximately 30* with the longitudinal axis of each troughlike member to cause said primary pellets to move down said path; said path being sloped downwardly and the trailing edge of each troughlike member in said path being located at a lower level than the leading edge of the immediately preceding troughlike member; and the vibration in operation forming said primary pellets into hard pellets.
Claim 2
Dependent Claim
32 words
Apparatus according to claim 2 wherein said vibrator means is electromagnetic and the force acting on the armature thereof makes an apparent relative phase-angle with its direction of motion of substantially 90*.
Claim 3
Dependent Claim
53 words
Apparatus according to claim 2 including a first stage including: a. a first plurality of said troughlike members; b. a second stage comprising a second plurality of said troughlike members; c. first vibrator means for causing vibration of said first stage; and d. second vibrator means for causing vibration of said second stage.
Claim 4
Dependent Claim
37 words
Apparatus according to claim 4 wherein the vibration of each troughlike member is at 20* to the horizontal and the plane of vibration is at an angle of 30* with the longitudinal axis of each troughlike member.
Claim 5
Dependent Claim
49 words
Apparatus according to claim 2 wherein each troughlike member is caused to vibrate at 60 cycles per second, the vibration of each troughlike member is at 20* to the horizontal and the plane of vibration is at an angle of 30 with the longitudinal axis of each troughlike member.
Claim 6
Dependent Claim
50 words
Apparatus according to claim 3 wherein each troughlike member is caused to vibrate at 60 cycles per second, the vibration of each troughlike member is at 20 * to the horizontal and the plane of vibration is at an angle of 30* with the longitudinal axis of each troughlike member.
Claim 7
Dependent Claim
50 words
Apparatus according to claim 4 wherein each troughlike member is caused to vibrate at 60 cycles per second, the vibration of each troughlike member is at 20 * to the horizontal and the plane of vibration is at an angle of 30* with the longitudinal axis of each troughlike member.
Claim 8
Dependent Claim
14 words
Apparatus according to claim 2 wherein each troughlike member is of semicircular cross section.
Claim 9
Dependent Claim
55 words
Apparatus according to claim 2 wherein said means for feeding primary pellets includes a vibratory conveyor for a bed of said powderous material, a plurality of nozzles positioned above said vibratory conveyor for supplying a liquid binder therethrough to form said primary pellets, and screen means to separate said primary pellets from surplus powderous material.
Claim 10
Dependent Claim
55 words
