The invention relates to the technical field of sludge waste utilization, in particular to a method for preparing aluminum sludge ceramsite. , and then transported to the dryer, and then transported the ceramsite raw meal to the rotary kiln for roasting. After being classified and screened by the closed screening machine, the waste and the ceramsite smaller than the standard size were transported to the crushing device through the closed conveyor. , use the crushing device to crush and sieve and then transport it to the storage tank of the mixed raw materials, and then weigh and mix the mixed raw materials with the measuring instrument, and recycle the waste materials. The produced ceramsite can be used in roadbed materials, concrete aggregates, etc. It is widely used; the mixed materials are formed into agglomerates. After the sludge is processed, the ceramsite fragments are crushed, transported and recycled by the crushing device. Through further processing, the recycling rate of waste can be enhanced and the production efficiency can be further improved.

The invention provides a solid dispersion method of celecoxib and a preparation method of celecoxib capsules, and the solid dispersion method comprises the following steps: mixing the celecoxib with pharmaceutical adjuvants to obtain raw and auxiliary material mixed powder, and carrying out ultramicro jet milling and / or mechanical milling on the raw and auxiliary material mixed powder, wherein thepharmaceutical adjuvants at least comprise lactose monohydrate and lauryl sodium sulfate. The solid dispersion method disclosed by the invention not only overcomes the characteristic of poor preparation of a celecoxib preparation, but also solves the problem of slow dissolution of the celecoxib, and the preparation is good in stability, so that the preparation is consistent with an original developed preparation (Celebrex) in prescription and dissolution, and the quality consistency and bioequivalence of the celecoxib preparation and the original developed preparation (Celebrex) are ensured.

The invention belongs to the field of biomedical instruments and relates to a liquid nitrogen medium / low-temperature crusher for a biological sample. The liquid nitrogen medium / low-temperature crusher comprises a bottom plate, a limiting fork, a stand column, a lever, a sample cup, sample cup cover, a sample pressure head, a horseshoe-shaped cushion block and a pressurizing slider. A use method of the liquid nitrogen medium / low-temperature crusher comprises the steps of: placing the biological sample at the bottom of the sample cup, pouring liquid nitrogen, covering the sample cup cover, placing the sample pressure head into a hole in the center of the sample cup cover, meanwhile, placing the horseshoe-shaped cushion block so as to erect a circular disc shaped structure on the upper end of the sample pressure head on the horseshoe-shaped cushion block, suspending the sample pressure head in the liquid nitrogen to decrease the temperature of the sample pressure head, removing the horseshoe-shaped cushion block after the temperature of the sample pressure head is decreased, lowering the sample pressure head onto the biological sample, moving the sample cup, the sample cup cover and the sample pressure head to lean against the limiting fork on the bottom plate, and forcibly pressing the lever to transfer the pressure of the lever by the pressurizing slider on the lever to the biological sample in contact with the lower end of the sample pressure head via the sample pressure head, thereby crushing the low-temperature solid-state biological sample in the liquid nitrogen.

A high-speed interlayer-shearing pulverizator for preparing nanoparticles is composed of high-speed motor, supporting frame, movable and fixed sealing plates, gas or liquid circulating pump, main cylinder, multi-hole static plates, multi-hole moving plates, oil sealing, feeding tank, discharging valve, etc.

The invention discloses a technology of preparing a nanometer traditional Chinese medicine material by liquid-phase shear dispersion. According to the technology, a traditional Chinese medicine material is used as a raw material, and the nanometer traditional Chinese medicine material having a particle diameter of 50-300 nm is rapidly prepared by utilization of a high-shear dispersion smashing technology. The traditional Chinese medicine material can be prepared into solid nanoparticles and also can be prepared into nanometer traditional Chinese medicine suspension.
