1. Site construction
Selection of a crusher, crushing preferably rectangular space (40m × 60m). If there are more than two broken airport sites, it must be larger. The site is first hardened, and various mechanical equipment is used to cast the concrete foundation. The location, size and height of the foundation are determined by the equipment and installation drawings.
2, crushing processing management
After the equipment is installed, a full-time staff will be set up to operate the crusher. When the equipment is first crushed, mechanical running-in and commissioning work should be carried out. Especially the debugging work of the discharge particle size. The aggregates of various specifications produced by the screening test shall be mixed in a certain proportion after the single-stage matching of the screening test. If the specified requirements are met, the production may continue; if the requirements are not met or the ratio is out of balance It is necessary to adjust the crusher hammer and vibrating screen holes until it is suitable.
3. Control during production
After the crushed aggregate has reached the requirements through the screening test, the visual density, water absorption, needle-like content, soft stone content and mud content of the aggregate are tested. After all the test results meet the requirements, the scale can be large. Production of gravel aggregates. In the production, there must be a loader for the stone, and the qualified aggregates produced must be transported to the designated site. The tester tests the produced aggregate according to the test frequency required by the specification. The test contents include screening, crushing value, apparent density, needle-like content, soft stone content and mud content, etc., and problems are solved in time. Screening tests (including particle size differences and dust content standards) should be timely and accurate. If problems occur, check the shaker and dust collector.
On-site staff includes general responsibility for crushing, mechanical operators, quality inspectors, mechanical repair and maintenance personnel, upper stone and transport personnel. On-site personnel have more observations, more movements, and more connections. Find problems and resolve them in time.
The opener is the core working component of the planter. The working principle of the double disc opener is two grooved discs, which are inclined to each other and intersect at one point. Working under the action of soil reaction, the grooved disk is supported by the opener bearing. With the continuous improvement of agricultural production efficiency, more and more farmers are using high-speed planters, and the speed of sowing is getting faster and faster. Due to the smaller diameter of the grooved disc, the relative rotational speed of the bearings of the planter is higher. Bearing failure and shaking will directly affect the effect of seed metering, and seeder bearings are generally closer to the ground, and are more susceptible to debris and weeds, so the reliability of the opener bearing is particularly important.
