Inspection batch unit for quality inspection and acceptance of mine engineering

(1) The concept of the inspection lot and its significance in the quality control of the project According to the "Consolidated Standard for the Acceptance of Construction Engineering Quality") GB 50300-2013, the inspection lot is put together for inspection according to the same production conditions or according to the prescribed method. a test body consisting of a certain number of samples. Because its quality requirements are basically uniform, it can be used as the basis for inspection. The inspection lot is the smallest unit of engineering acceptance, and is the basis for larger inspection lots and sub-projects, and even the entire construction project quality acceptance. The establishment of inspection batch unit embodies the principle of quality control and timely control. It can detect and deal with quality problems at an early stage and avoid losses caused by quality.
(II) Division of inspection batches “Unified standard for construction quality acceptance of construction projects”) GB 50300→2013 stipulates that each sub-project can be based on the principle of consistent with the construction method and easy to control construction quality, according to work class, structural relationship or construction section It is divided into several inspection lots; or it is divided according to the principles of construction cycle, quality control or professional acceptance in the sub-project.
Construction and acceptance of open-air coal mine ore, nonferrous metals and other provisions of sub-projects can be tested by one or several process batches of components. The regulations stipulate that the inspection lot can be divided according to the actual needs of construction and quality control and acceptance. For example, the grouting reinforcement sub-project in open-pit mine slope treatment can take the construction quality of each grouting hole as the inspection content of an inspection lot.
The inspection and acceptance of coal mine roadway engineering does not have the content of inspection batch, and the smallest acceptance unit is a sub-project.

Fat Press Machine

Connect oil express lead you to remove the fat from meal which the fat contains of final meal is about 8%. It help customers get high quality and good appearance of products.
Working Principle

When the cooked meal feed in to express, as the two screw pitch is gradually reduced along the discharge end, the bottom diameter is gradually increasing, so the raw material in second screw slot is gradually compressed, the pressure is up to 1.5Mpa. The oil and water outflow from stainless steel filter mesh with the continuous compression of raw material. Filter pore size is from φ4.5mm to φ1mm descending arranged, oil and water are collected by bucket, squeezed bread fall from the discharge port , and dry in the dryer which transport by screw conveyor.
