Abstract
Abstract A high speed blending, weighing, and loading system is provided for handling and processing of materials having two or more ingredients. This system includes a primary weigh-blend hopper having a chute for receiving materials which, if necessary, are conditioned by breaking up of lumps of material in the chute and then passed on to the primary weigh-blend hopper for weighing and blending thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
146 words
A high sPeed blending and loading system, comprising, a primary weigh-blend hopper means having a hopper of substantially rectangular shape formed of two pivotally mounted gates defining the sides and bottom of said hopper where said gates are closed, said hopper being provided with spaced partitions running lengthwise thereof defining chambers therebetween for successively receiving materials, fulcrum means for supporting said weigh-blend hopper means, a weighing system mechanically coupled to said fulcrum means for continuously weighing the materials in said weigh-blend hopper means, a conveyor system having a hopper located below said weigh-blend hopper for receiving the materials from said weigh-blend hopper upon opening of said gates, with said materials being blended by gravity as they fall to said conveyor hopper, and blending hopper means positioned to receive the blended material conveyed by said conveyor means for further blending and holding thereof and for further processing.
Claim 2
Dependent Claim
146 words
A high sPeed blending and loading system, comprising, a primary weigh-blend hopper means having a hopper of substantially rectangular shape formed of two pivotally mounted gates defining the sides and bottom of said hopper where said gates are closed, said hopper being provided with spaced partitions running lengthwise thereof defining chambers therebetween for successively receiving materials, fulcrum means for supporting said weigh-blend hopper means, a weighing system mechanically coupled to said fulcrum means for continuously weighing the materials in said weigh-blend hopper means, a conveyor system having a hopper located below said weigh-blend hopper for receiving the materials from said weigh-blend hopper upon opening of said gates, with said materials being blended by gravity as they fall to said conveyor hopper, and blending hopper means positioned to receive the blended material conveyed by said conveyor means for further blending and holding thereof and for further processing.
Claim 3
Dependent Claim
33 words
A high speed blending and loading system as recited in claim 1, and additionally a chute positioned at the top of said primary weigh-blend hopper means for receiving the materials to be blended.
Claim 4
Dependent Claim
24 words
A high speed blending and loading system as recited in claim 2, and means positioned in said chute for conditioning of the received materials.
Claim 5
Dependent Claim
41 words
A high speed blending and loading system as recited in claim 2, wherein said means in said chute for conditioning of said received materials consists of a rotary crusher having spaced elements thereon for conditioning of received materials as it rotates.
Claim 6
Dependent Claim
25 words
A high speed blending and loading system as recited in claim 1, and additionally means for opening and closing said gates forming said weigh-blend hopper.
Claim 7
Dependent Claim
