The utility model discloses a surface self-adaptive high-precision grinding device for a precision metal workpiece for a vibrating table, and relates to the technical field of precision metal workpiece grinding. The device comprises a base. A first transmission wheel, a transmission belt, a second transmission wheel, an adapter block and a grinding wheel are conveniently driven to rotate in a transmission mode through a second driving motor, the surface of a workpiece is conveniently ground through the grinding wheel, and limiting plates are conveniently driven to be connected to clamp and limit the workpiece through two second electric hydraulic cylinders; the first electric hydraulic cylinder is used for conveniently driving the workbench to ascend and descend so that the surface of the workpiece can be attached to the grinding wheel, the first driving motor is used for conveniently driving the half gear and the transmission gear to rotate, and the workbench, the silica gel pad and the workpiece can be conveniently driven to intermittently rotate through the shape characteristic of the half gear; and after the grinding wheel linearly grinds the surface of the workpiece, the position of the workpiece is rotationally adjusted, so that the grinding wheel continuously linearly grinds the surface of the workpiece.

This utility model discloses a crusher for agglomerated materials, including a frame, a crushing component, a grinding component, and a collecting box. The frame has a first working chamber, a second working chamber, and a third working chamber. The crushing component includes a crushing claw and a first screen. The crushing claw is rotatably installed in the first working chamber, and the first screen is disposed between the first working chamber and the second working chamber. The grinding component includes a grinding roller and a second screen. The grinding roller is rotatably installed in the second working chamber, and the second screen is disposed between the second working chamber and the third working chamber, with the grinding roller abutting against the second screen. The collecting box is slidably installed in the third working chamber, directly below the second screen. The agglomerated material to be crushed is fed into the first working chamber, which can crush the agglomerated material into fine powder. It has a simple structure, small footprint, convenient operation, and high crushing efficiency.

The utility model relates to the technical field of flour processing, in particular to a nutritional flour production device which comprises a box body, the interior of the box body is rotationally connected with the feeding pipe, one side of the feeding pipe is in pipeline connection with an air conveying pipe, the end, away from the feeding pipe, of the air conveying pipe is in pipeline connection with a refrigeration fan, the interior of the feeding pipe is uniformly and fixedly connected with a plurality of air dispersing pipes, one end of each air dispersing pipe is in pipeline connection with an air conveying pipe, and the end, away from the air conveying pipe, of each air dispersing pipe leads to the inner grinding disc; according to the utility model, through the cooperation of the refrigeration fan and the air dissipation pipe, cold air flow is conveyed to the inside, heat generated in the grinding process is absorbed, nutrient substance structures in grains are effectively prevented from being heated to be denatured or lost, and the produced flour is ensured to be high in nutritional value and good in quality, and the inner millstone, the middle millstone and the outer millstone are arranged, so that the production efficiency is improved. And multi-stage grinding from coarse to fine is realized, so that grains can be ground more uniformly and comprehensively, and the ground flour is finer and smoother.

The application discloses a vertical roller mill and a machine-made sand production system, and relates to grinding equipment technology. The roller mill comprises a grinding part, wherein a grinding disc and a grinding roller constitute part of the grinding part. The roller mill comprises a pre-milling part and an adaptive material blocking adjusting part. The pre-milling part is composed of a feeding center shaft and milling units, and the feeding center shaft is located above the grinding disc. The N milling units are uniformly distributed around the feeding center shaft, and the pre-milling part of the milling units is in contact with the grinding end face of the grinding disc. The adaptive material blocking adjusting part comprises a rocker seal frame, a material blocking device and a linkage assembly. The rocker seal frame serves as a grinding roller support and is installed on the roller mill rack. The material blocking device comprises a fixed material blocking device and a sliding material blocking device combined with the fixed material blocking device through vertical movement, and the two devices jointly form a surrounding blocking structure. The linkage assembly connects the rocker seal frame and the sliding material blocking device, so that the rocker seal frame drives the sliding material blocking device to move upwards through the linkage assembly. Through the technical innovations, the performance of the vertical roller mill is comprehensively improved.
