Abstract
The invention relates to the technical field of non-metallic material production, in particular to a bentonite production process. In order to overcome the defects in the prior art, the bentonite production process achieving classified filtration is provided. According to the bentonite production process achieving classified filtration, ore is fed into a dryer to be dried through an auger conveyor and is fed into a raw material warehouse to be homogenized through an elevator; and the ore and sodium carbonate are discharged into a Raymond mill feeding auger through an electronic scale according to the proportion in the formula, fed into a Raymond mill to be mixed and levigated and then fed into a finished product warehouse to be subjected to a homogenization reaction through a finished product elevator, and bentonite or alkaline bentonite is produced and is packed and warehoused through a packaging machine. A classified filtration process is also involved before the ore enters the dryer. According to the classified filtration process, preliminary filtering is firstly carried out through a filtering screen, small particles directly pass through the filtering screen, enter the dryer through a discharging port and are dried, and large particles enter the dryer and are dried after entering a smashing paddle and being smashed.

In order to solve the deficiency that prior art exists, the invention provides a kind of bentonite production technology of sizing screening.
The bentonite production technology of a kind of sizing screening in the present invention, ore deposit soil is sent in dryer by screw conveyor and is dried, homogenizing in raw material storage sent into by elevator, by electronic scale by ore deposit soil and sodium carbonate in fill a prescription in ratio under expect in Raymond mill feeding auger, feeding Raymond mill is mixed and finely ground, send into homogenizing in warehouse for finished product by finished product elevator to react, produce bentonite or alkaline bentonites soil, warehouse-in is packed by packing machine, sizing screening technique is also comprised before entering dryer, described sizing screening technique is for first tentatively to filter through filter screen, granule directly to be entered dryer from discharging opening by filter screen and dries, bulky grain enters to be pulverized oar and carries out entering dryer and drying after pulverizings is processed.Eliminate large particle after being filtered by filter screen, improve drying efficiency.
As preferably, also comprise filter screen and remove technique, described filter screen removing technique is that sliding bar moves back and forth along filter screen.Sliding bar slides up and down the bentonite can removed and shine online accumulation, prevents screen cloth from blocking.
As preferably, rotational speed regulation technique is dried in weigh technique and revolution of the bentonite also comprised before entering dryer, described rotational speed regulation be according to sizing screening technique after bentonite weight regulate, being high rotating speed during bentonite Heavy Weight, is the slow-speed of revolution when bentonite is lightweight.After guaranteeing bentonite oven dry by rotational speed regulation, aridity is even.
As preferably, described rotational speed regulation formula is:
As m<=m0, r=0.5*r_max;
As m>m0, r=0.8*r_max;
Wherein: m is bentonite weight, mo is pivot weight, and r_max is maximum (top) speed.
Beneficial effect of the present invention, is eliminated large particle after being filtered, improve drying efficiency by filter screen.
