    Abstract: A hybrid incline/horizontal screen for separating particulate material into predetermined size fractions, the screen having multiple screen decks mounted on a frame, at least one uppermost screen deck having an inclined receiving end and a horizontal discharge end. Each screen deck has a screening medium with predetermined sized openings that screens the particulate material. The screen decks are in stacked relationship, the upper screen deck having the largest screen medium openings, the openings becoming progressively smaller the lower the screen deck is mounted on the frame. The inclined receiving portion of the one or more uppermost screen decks provides for rapid material separation and conveyance through the upper screen decks to the lower screen decks while the horizontal discharge end reduces the tendency for the material to pile up (snowball) and maintaining a more uniform material bed, while providing for a shorter, more transportable screen. The screen incorporates perforated and non-perforated feed boxes at the screen deck receiving end to protect the screen decks from dropping material impact loads, to provide for an extended screening surface, and to pre-distribute the material as it falls into the feed box.

    Abstract translation: 一种混合倾斜/水平屏幕，用于将颗粒材料分离成预定尺寸的分数，所述屏幕具有安装在框架上的多个屏幕甲板，至少一个最上面的屏幕甲板，其具有倾斜的接收端和水平排放端。 每个筛板具有筛分介质，其具有预定尺寸的开口，筛分颗粒材料。 屏幕甲板处于堆叠关系中，上屏幕甲板具有最大的屏幕介质开口，开口逐渐变小，屏幕底板安装在框架上。 一个或多个最上面的筛板的倾斜接收部分提供快速的材料分离和通过上筛板甲板输送到下筛板，而水平排放端减少材料堆积（雪球）的趋势并保持更多 均匀的材料床，同时提供更短，更易于运输的屏幕。 屏幕在屏幕甲板接收端处包含穿孔和非穿孔进料盒，以保护筛网甲板不会掉落材料冲击载荷，提供延长的筛分表面，并在材料落入进料箱时预分配材料。

    Abstract: A method of manufacturing a large stationary, aggregate processing screening tower by fabricating weldment modules and preassembling them with aggregate processing equipment internal within the weldment modules, transporting the preassembled weldment modules to a field work site where the tower is to be erected on a foundation, aligning the modules and stacking the modules in layers and then bolting adjacent modules together. A large stationary, aggregate processing screening tower has weldment modules preassembled with aggregate processing equipment internal within the modules. The preassembled modules are stacked up on one another and secured together and can receive aggregate product at the top module and the product is processed by screening and sizing as it moves downwardly by gravity through the modules and their processing equipment for final clarification and collection of the product.

    Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff (a mixture of grain kernels, chaff, weed seeds, and other organic matter) from straw (plant stalks), and returning the straw to the field. This is preferably carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and preferably the harvesting unit and vehicle, are designed to make this possible. This avoids difficulties caused by the poor material flow of graff. Various details of the equipment are also novel.

    Abstract: A screen is disclosed which, in certain aspects, has screening material between opposed frame sides and one or more lower strips beneath the screen. In one aspect these strips are only inteconnected via their ends and not along their lengths. In certain aspects, a plurality of lower strips are bonded to the screen and extend across the screen from one frame side to the other. In one aspect one or more of the strips has one, two, or more humps or ridges corresponding to one or more corrugations in a corrugated perforated plate and/or corrugated screen assembly which is on the plate or, with no plate present, on the strips. In another aspect instead of the strips a solid corrugated perforated plate is used. In one aspect openings or perforations through the plate are triangular. In one aspect the screen is undulating screening material and lower portions of the screening material are bonded to a plate or to strips. Optionally screen mounting hooks or frame edges or screen edges may be used with such screens. A screening apparatus or shale shaker is disclosed which uses such plates and screens.
