Prepare construction organization design or special construction plan Prepare equipment entry plans, plan for the use of resources such as labor, materials, and equipment, and organize them in an orderly manner. On-site facilities should have starting conditions Unpacking the device When the machinery and equipment are unpacked, the construction company, construction unit, supervision unit, and supplier Box number, box number and packaging Equipment names, specifications and models, important parts and components also need to be checked and accepted according to quality standards Random technical documents (such as instructions for use, certificates of compliance, packing lists, etc.) and special tools Whether there is a defect, whether the surface is damaged or rusted Other matters that need to be recorded Basic measurement line Set baselines and benchmarks The construction unit that undertakes the civil engineering works shall hand over the measurement network points, including the crucial main axis, together with the transfer of the factory building and the basic conditions. in principle Easy to install and test Helps to maintain without being destroyed Sculpted clearly and easily Claim Prior to the placement of machinery and equipment, according to the layout of the process and according to the measurement control network or related building axis, edge line, elevation line, delineate the installation of the baseline and reference point For mechanical equipment that has mechanical connection with other equipment, a common installation reference line and reference point should be designated For mechanical devices that have no mechanical connection with other devices, the allowable deviation of the mounting base line for locating the base surface, line or point is ±20mm, and the allowable deviation from the mounting reference point is -10～+20mm. For mechanical equipment that has mechanical connection with other equipment, the allowable deviation of the positioning base surface, line or point from the installation reference line is ±2mm, and the allowable deviation from the installation reference point is ±1mm. Permanent baseline and benchmark Longer installation periods and production inspections require long-term retention of baselines and benchmarks, permanent centered targets and permanent reference points Roll Crusher Applications Roll Crusher,Double Roll Crusher,Jaw Roll Crusher,Lab Roll Crusher Shenyang Sanland Mining Equipment Manufacture Co., Ltd. , https://www.sanlandcrusher.com
Roll Crushers are simple in design and construction, long-lasting, economical, and versatile. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or Cone Crusher. Product size is much more consistent. Both oversized pieces and fined are minimized. Wet, sticky materials are more easily handled.
The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple. Internal parts are readily accessible.
Typical feed materials for Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.
